Medical control system and medical sterile room with control system

description

Background of the invention

The invention relates to a medical control system for a medical sterile room, such as an operating room, with which a user, for example a medical staff, such as a surgeon, an operating room nurse or a

Nurse, in particular medical devices, such as a suction device or a projector, but also, for example, control components of a hall equipment. The medical control system detects a (control) input of a user and processes it to perform a control. In addition, the invention relates to a medical sterile room with a control system according to the independent claim.

State of the art

From the prior art, different control systems are known which find application in medicine. A common basic problem of this

medical control systems is that used in medicine technical devices are usually non-sterile (not sterile) and therefore, during an operation, for example, the unsterile devices must be operated from a sterile area or remotely controlled. For this purpose, a sterile barrier between the user and a control unit of the control system must be established and maintained or the control unit itself must be sterile.

Currently, for a control of a non-sterile device in particular a

Voice control is used or via an input device, a transparent sterile coating for a physical training of a sterile barrier. However, these opportunities entail considerable risks. The voice control harbors in particular, the risk of a potential error by unrecognized

Speech segments or by a falsification of voice commands due to a necessary in the sterile field mask. In addition, voice commands can be misinterpreted by speech recognition due to a high level of noise during surgery, such as operation of a surgical suction device or by talking medical personnel in the room.

On the other hand, if input devices with a transparent sterile coating are used for the control, this requires an increased space requirement in an already very narrow sterile operating environment and also involves the risk that the transparent coating will be damaged, for example, during an input. Destruction of the sterile barrier can result in particular in contamination of the user and thus of the patient. In addition, the sterile coating falsifies a

Presentation of the input device and makes it difficult for the user to enter.

US 2017/0228104 A1 discloses a system and a method which enable a doctor to undergo a medical procedure during a medical procedure

Control unit to interact. The system uses a projector to turn on

To project menu surface image onto a screen. An optical one

Detection system detects gestures of a user and forwards the detected gesture to a control unit, which interprets the gesture and performs an appropriate control. The controller is connected to an external display to display images and other information on the display. The display is arranged close to the patient on one side. However, this side on which the display is arranged must be kept free by operating theater operators in order not to obstruct a field of view on the display. In order to see the information on the display, the operators must also be on the opposite side of the display and a viewing angle on the display must not exceed a certain angle of reflection. The display takes up a lot of space in small operating theaters and, in addition, poses noticeably impairing requirements and restrictions to the operating theater operators, who have to be guided by the position of the display. Also, the information is not available to all surgical stakeholders but only those who have a good view of the display. The system is also designed so that its important components, such as the projector, Detecting device, control unit and display, are arranged in the sterile area.

Summary of the invention

It is therefore the object of the invention to avoid or at least mitigate the disadvantages of the prior art and, in particular, to provide a medical control system which allows safe, simple and reliable control out of, in particular, a sterile area and offers the possibility to provide as far as possible to all (OP) participants an as yet unattained assistance function.

This object and the objects of the invention are achieved in a generic medical control system according to the invention in that the medical control system projects a projector, which projects a projection, preferably in the form of a graphical user interface, onto a projection surface

Detecting device, which in the region of the projection surface a,

Preferably, manual, input or movement or a residence of an interaction component detected by a user, and an (electronic) control unit (ECU), which controls the projector and by the

Acquisition device detected input processed and interpreted or in control commands for controlling the projector and / or other technical

Components / devices converts. It was recognized that the

Control system according to the invention offers the opportunity to represent relevant medical information and that in the projection itself, whereby a display can be omitted and each (OP) parties regardless of its standing position attained a previously unattainable overview of the operation happening.

In principle, the invention thus provides for a projection / imaging, in particular a graphical user interface, on a sterile surface in which

Input / Operation The sterile user himself remains sterile. Thereby, no further measure to create a sterile barrier, such as by a

Sterile cover, necessary. By visual representation is, in contrast to one Voice control, the projection and thus the input possibility for the

Users visualize what further reduces a faulty operation. For example, with the medical control system according to the invention, the user can control only the projection, for example, in order to display an OR instruction or data on the patient and, in particular, move on to a next step in the OR guide, or a next one Page of the patient's data. In particular, the user can also display live data of an oxygen saturation or a heart rate. On the other hand, the user can also control other technical devices, in particular of a medical nature, or components by means of his input. For example, it is possible by the control system according to the invention to control an inflow of a medicament in a syringe pump (as an external medical device), so that the user, in addition to a possible visual projection of the current data on the drug, via a graphically projected user interface an absolute value can enter or over projected buttons "+" and a supply value of the drug increase or decrease. The control system according to the invention accordingly performs a conversion of an input of a user into a

(technical / machine-readable) control command and can be used for different tasks.

Advantageous embodiments are claimed in the subclaims and are explained below.

In a preferred embodiment, the control system may comprise a sterile and an unsterile region, wherein the projector and the detection device are arranged in the non-sterile area and the projection surface is arranged in the sterile area, and a sterile barrier is provided between the sterile area and the non-sterile area is that which the projector and the detection device, in particular exclusively, can penetrate by electromagnetic radiation. The sterile barrier causes a separation between the sterile area and the non-sterile area through a sterile barrier, wherein in particular only

electromagnetic radiation of the projector to one in the sterile field

arranged projection surface projected / sent and also a detection by the detection device by electromagnetic particular Radiation takes place. The sterile barrier may be merely a virtual sterile barrier with a designated distance between the sterile and non-sterile area, as well as a physical sterile barrier such as a glass pane or other in the visible light (electromagnetic radiation) permeable (sterile) barrier, such as For example, plastic or Plexiglas be.

In a further preferred embodiment, the projector can

Laser module / have a laser with which the projector projects a laser projection on the projection surface. Lasers with their focused, coherent and very straight-line electromagnetic radiation in the visible range are particularly well suited for a visual representation. The laser module is universal and versatile, with the radiation naturally moving in the low power range to avoid any eye damage to the user.

As an alternative to the laser module, the projector for projection may also preferably have a light source in the form of a non-thermal radiator, preferably an LCD or an OLED, and an adaptable optical system. Similar to a beamer can thus a particular multi-colored image directly on the

Projection surface are projected.

Advantageously, the projection surface, preferably in the sterile field, a surgical cover or a surgical drape. These

Thus, the embodiment provides that the sterile room does not need to be supplemented with an additional separate projection surface, but rather that a

existing / existing sterile surface, such as the one

Operation cover or a surgical drape, is used by the control system as a projection screen. This allows the user to display the projection directly on a sterile (projection) surface using the projector and to make a (control) input via the control system at or in the area of this projection. It would also be possible, for example, to provide a graphic representation, in particular a multicolored graphic representation, onto which, in particular, single-colored surgical cover is projected. Patient data, images or measured values can thus be displayed in a clearly visible manner for the user (surgeon), preferably in direct view of the procedure. By an immediate proximity of the projection surface to the user (Surgeons), this does not have to move, turn or run, but can perform an input in its immediate vicinity. Likewise, a

Be provided with a sterile cover (surgical cover or surgical drape) on the side table and projected on this sterile cover, the projection using the projector.

Preferably, the projection surface may be a matte glass plate in the sterile room. A glass plate can be relatively well through the flat surface

disinfect. Due to the matt / milky design, the projection is easily recognizable and can be seen from both sides of the glass plate. In particular, the glass plate can be arranged vertically in the sterile room, so that the matte glass plate is a kind of blackboard. In particular, the glass plate itself forms the sterile barrier. Thus, one side of the glass plate is in the sterile area whereas the other side is in the non-sterile area.

In a preferred embodiment, the detection device may be adapted / configured for the three-dimensional surface contour of

Projection surface, in particular those of the operation cover or the

Surgical cloth, to capture, and further the electronic control unit be adapted to control the projector so that the projection on the

Projection surface on the detected by the detection device

Surface contour is adjusted. By detecting the surface contour of the projection surface, there are several advantages. On the one hand, a projection is not distorted by this, or a projection distorted onto the uneven projection surface is corrected by the control unit and projected with the projector, and on the other hand by this detection / recognition a region suitable as a projection surface, for example the area of an OP cover , be recognized and projected onto this area the projection projected. This is to serve that

for example, when moving a side table on which a

Operational cover is placed, the projection screen of the control system accordingly "mitwandert".

In particular, the detection device in a preferred

Embodiment, a camera system and / or an ultrasonic device (with Ultrasonic transmitter / ultrasonic receiver). In particular, when using a camera or a camera system for the detection device, this is a stereo camera with which the interaction component can be detected in three dimensions and subsequently processed and interpreted in the control unit. By means of an ultrasound device with ultrasound transmitter and ultrasound receiver, a distance and position of the interaction component can be determined.

Alternatively or additionally, the detection device in a

Embodiment have a laser. With a laser (and a corresponding detector) can be effectively determined a distance and a position of the interaction component. Preferably, in the embodiment in which the

If the projector has a laser module, this laser module can also be used directly (in combination with a detector such as a photodiode) as a detection device. Thus, with a single laser module both the projection and a

Capture of the input of the user can be realized.

It is preferred if the medical control system can have an interface and with at least one other, in particular

medical-technical / medical, device, such as a suction device, via the interface (in particular data technology) is connected, so that the user with the medical control system via the interface (on) controls the device. In addition to providing a visual representation on a projection surface by the projector, the equally important task of the control system is to allow interaction with the user and to capture his (control) input for other devices. This (control) input allows the user to control the medical device (s). For example, the user can thus control a suction device. The control system has for this purpose the interface, for example, a wireless

Interface via Bluetooth® or WLAN, or a wired, for example via a plug / adapter, for connecting the control system to other devices or components. This interface can be a variety of different devices or components connect to the control system. In particular, the interface is directly to or with the electronic control unit (ECU)

connected / coupled. In a preferred embodiment, the medical control system may include a saloon equipment, such as a surgical light or a height-adjustable operating table, and the user through the medical control system

Control room equipment of the sterile room. Here you can meet needs

Project different projections onto the projection surface depending on the application. Multiple input devices, such as a keyboard or control panel for

Hall lighting, surgical lighting, operating table (height adjustment), eliminated and the control system of this embodiment allows for only a single

customizable and controllable projection the control of various hall features. This eliminates mechanical components (no wear and tear of the

Sterility problem) and less space is needed.

Particularly preferably, the projector, the detection device and the control unit can be combined in a single, preferably portable, control module. A portable control module may advantageously be used at different locations as needed and in the vicinity of different ones

Projection surfaces are positioned. Preferably, this control module has its own energy source, such as a (lithium-ion) battery, so that the

Control module is self-sufficient.

In a preferred embodiment, the projector and the

Detection device to be arranged on a ceiling and / or on a wall of the sterile room. By this arrangement are in a sterile room the

Detection device and the projector off and trouble-free against the sterile area and the user arranged.

In particular, the control system may control an imaging source, such as a monitor, via the interface. Preferably, the projection has a

Menu navigation for a picture loop through to different monitors.

In accordance with an optionally independent aspect of the invention, the medical control system may include a computer-aided navigation system / computer-aided 3D navigation using anatomical data of the patient. Preferably, the computer-assisted navigation system is provided by GPS or another equivalent positioning system. The computer-assisted navigation system assists the operating theater operator by connecting captured 3D data or position data with anatomical data of the patient.

In particular, the computer-aided navigation system based on anatomical data of the patient, in particular on the basis of data of a

Computed tomography or a magnetic resonance tomography of the patient, and project based on a position and position of the patient by means of the projector, a projection on an area of the patient in which an operative procedure is performed to visually assist the user with the help of augmented reality / augmented reality. For example, regions to be treated can be marked or colored, or an incision to be made can be drawn. The computer-aided navigation system can in particular by means of

Detecting device or a stereo camera capture the (real) position and the position of the patient in space, connect this data with (stored) anatomical data of the patient, such as a 3D computed tomography image of the patient, and projected or visualized, preferably in accordance with a

predetermined operation, via the projector a surgical target and / or

surrounding tissue structures on a predetermined area of the patient. Thus, a spatial orientation during the procedure is facilitated. Thus, relevant medical information is not displayed on an external display, but also projected directly to the appropriate location or area. The computer-assisted navigation system preferably superimposes the patient's real data with the anatomical data of the patient. In particular, the computerized navigation system is adapted to constantly acquire a current position and location of the patient for seamless updating of the image data.

The user is familiar with the medical control system and the

Computer-aided navigation system provided an augmented reality for high-precision surgical navigation. Optionally, anatomical landmarks may also be arranged on the patient to determine a position and location of the patient

To capture patients even better. Additionally or alternatively, an instrument may also be provided with landmarks in order to detect the position and position of the instrument in space and to integrate it into the computer-assisted navigation system.

For example, a function of a surgical instrument may only be activated be when the surgical instrument is placed or inserted exactly at the predetermined location of the patient to provide another safety mechanism.

According to a further preferred embodiment, relevant

medical data / information is projected onto the projection surface, in particular a dynamic graphic, preferably multi-colored, representation, such as in the form of an image, a recording, a 3D representation, an OR guide, current data of the patient, in particular current data of oxygen saturation and / or a heart rate, and / or a patient's datasheet. In addition to the control, the medical control system also serves to display relevant (medical) information. Thus, no additional display device is needed, but pictures, recordings instructions, etc. are directly on the

Projection surface projected. Thus, in a small operating theater space can be saved by the elimination of the display space, it will be free standing room for other surgical participants / assistants and regardless of location, all surgical parties have a good view of the information.

With regard to a generic medical sterile room, such as an operating room, the objects and objectives of the invention are achieved according to the invention in that the medical sterile room has a control system according to the invention. The fact that the sterile room according to the invention has the control system according to the invention, this allows the user a safe, simple and reliable control, especially from a sterile area out.

The invention will be explained below with reference to preferred embodiments with the aid of the accompanying figures. The figures are schematic in nature and are intended only to aid understanding of the invention. Identical elements are provided with the same reference numerals. The features of the various embodiments can be interchanged. Show it:

Detailed description of preferred embodiments

FIG. 1 shows a schematic representation of a device according to the invention

Control system 1 of a first preferred embodiment. The control system 1 comes in a medical sterile room 2 according to the invention of a first

preferred embodiment in the form of an operating room for use. The operating room 2 has peripherally walls delimiting the space 3 as well as a ceiling 4 and a floor 5. The operating room 2 has two more

(Different) areas 6, 7 in space, namely a central sterile area 6, in which the surgery or surgery on a patient 9 (shown here only schematically) is made or in which another medical

Action is performed, which requires a sterile environment, and a non-sterile area 7 (on both sides of the sterile area 6), in which also non-sterile devices can be arranged. Between the sterile area 6 and the non-sterile area 7, a sterile barrier 8, whether in the form of a predefined defined distance or a glass pane, is provided between the sterile area 6 and the non-sterile area 7. At this point it should be pointed out again that no patient 9 is needed for the invention, but that only one action, which requires a sterile area 6, is crucial. The sterile area 6 may, for example, also be a laboratory area of a (medical) laboratory in which sterile experiments are carried out. In the operating room 2, not the entire operating room 2 is sterilized, since this time, technically and financially difficult to perform, but only an operating table 10. On this operating table 10, the patient 9 is stored. The patient 9 is thereby around the surgical site of the operation by means of a one-way - surgical cover / operation cover 11, usually kept in a bright plain green, turquoise or light blue shade, sterile shielded. The surgical cover 11 forms a boundary of the sterile area 6. The medical staff (not shown here) wears a non-sterile turquoise or light blue surgical area clothing with pants, top, surgical shoes, surgical hood and surgical mask, on which a sterile Surgical gowns and sterile gloves are drawn. This allows the medical personnel to approach the sterile area 6 and the surgical site without running the risk of contaminating the sterile area and consequently the patient 9.

In FIG. 1, in the right non-sterile area 7 on the wall 3, in an upper area of the operating room 2, a projector 12 and a projector 12 are shown schematically

Detecting device 13 attached or arranged. In this embodiment, the projector 12 has a laser module 14 which projects a visual projection / presentation 16 onto a projection surface / projection surface 15. The projection surface 15 is arranged in the sterile area 6. More specifically, this is in this

Embodiment a defined portion of the bright plain turquoise surgical cover 11 of the patient 9, the projection surface 15. Due to the laser projection of the projector 12, which falls at an oblique angle to the sterile surgical cover 11, this projection 16 does not change sterility of the sterile area. 6 ,

The medical staff (not shown here) can use the visual / graphical projection 16 in the form of a graphical user interface (also a

User interface of any device which is projected for visualization) or an operating instructions or a data sheet to the patient 9 on the monochrome projection surface 15 clearly recognize. For example, buttons (buttons), similar to a computer program, can be imaged on the screen 15 or other visual representations (monochrome or multicolor), such as an image, a shot or a 3D representation. For example, a region of the patient may be marked by the projection 16 in which, for example, the procedure is performed. Or it could mark a point in the patient's body through which a surgeon can introduce a minimally invasive device. The user, in this case a medical staff, uses the

Projection surface 15 consciously an input by the medical staff in particular a certain gesture / movement or a stay with one

Interaction component 17 (see Fig. 2) performs. It can the

Interaction component 17 may be a hand or a finger or a defined instrument. The instrument may be both a medical instrument (e.g., needle holder) and a specially adapted input instrument such as a special pointer. In the present embodiment, the input is made by a finger, which taps a projected key similar to a touch display.

The detection device 13 is adapted to the input of the

To capture interaction component 17. In particular, the detection device 13 may include a photodiode that measures the reflected electromagnetic radiation and a stereo camera to detect three-dimensional structures. The detected input is then forwarded to an electronic control unit (ECU) 18. The detection takes place in the detection device 13 in that

Electromagnetic radiation / radiation, here in the visible range, are radiated from the sterile area 6 back to the detection device 13 in the non-sterile area 7, so that the sterile barrier 8 is once again penetrated only by electromagnetic radiation. Accordingly, the sterile barrier 8 is not physically penetrated nor must it be in physical form, such as a sterile one

Cover can be formed, but can form in the simplest form only as a virtual sterile barrier 8 a defined distance between the sterile area 6 and the non-sterile area 7. Of course, the sterile barrier 8 may also be in the form of a transparent glass pane. In summary, therefore, in this preferred embodiment, only electromagnetic radiation penetrates the sterile barrier 8 and the sterility state of the sterile area 6 is maintained.

The ECU 18 is adapted to process and interpret the captured input to control commands to control the projector 12 or other devices or components. For interpretation, the ECU 18 has predefined and stored pattern templates that inform them about the input rated. The control system 1 also has at least one further interface 19 for the connection to further technical devices to the ECU 18 in order to serve as a central (remote) control element or central link and control commands

forward or accept data. Technologies such as wired interfaces 19 (adapter / plug) as well as wireless interfaces 19 via Bluetooth® or WLAN are possible. For this, the ECU 18 in a simplest form has a memory unit, a processing unit (CPU), and an input-output unit.

FIG. 2 shows a further preferred embodiment of a medical control system 1 according to the invention for a medical sterile room 2 in a schematic perspective illustration. Likewise, Figure 2 shows a partial section of a medical sterile room according to the invention 2 another preferred embodiment in the form of an operating room 2. The inventive

Control system 1 of this embodiment is shown in more detail with respect to the figure 1 and uses for a projection surface 15 a side table 20, on which an OP cover 11 is placed, so that again a sterile surface as

Projection surface 15 is formed. On this sterile projection surface 15 of the

Side table 20 projects the projector 12 with the laser module 14, which is arranged on the ceiling 4 of the operating room 2, the projection 16 in the form of a graphical user interface. A sterile area 6 is shown schematically as a three-dimensional block-like dashed volume within the operating room 2.

Outside this very roughly shown sterile area 6 is the non-sterile area 7. A user 21 or in the present case a medical

Operating personnel 21, for example an operating nurse or a surgeon, can use an outstretched index finger as an interaction component 17 for the graphical user interface

User interface 16 by making a predefined gesture on the

illustrated graphical user interface 16 performs. The side table 20 is arranged in the immediate vicinity of the user 21 for this purpose.

A detection device 13 in the form of a stereo camera and a photodiode arranged vertically above the projection surface 15 in the non-sterile region 7 of the sterile room 2 detects the input of the medical personnel 21. The projector 12 and the detection device 13 are in this embodiment at two different areas in the operating room 2 arranged. The

Detection device 13 forwards the detected input to the ECU 18, which evaluates and interprets the input of the medical personnel 21. About the

Interface 19 of the control system 1 is finally issued an input of the corresponding control command or it is controlled according to the input directly the projector 12.

In the operating room 2 more medical devices 22, such as a suction device, arranged. The over the interface 19

issued control command is wirelessly, here via Bluetooth®, forwarded to the suction device 22, which is controlled by this control command accordingly. For example, the suction device 22 can thus be switched on, a suction stage can be set or the suction device 22 can be switched off.

The operating room 2 further has a hall equipment 23, such as a surgical light / surgical lamp. The surgical light 23 can also be controlled via the control system 1. For this purpose, a control command of the control system 1, wired from the interface 19 to a light control of the operating light 23 is forwarded. The medical operating personnel 21 can thus make a change in luminous intensity, light cone shape or other change with the aid of the control system 1 in a simple and sterile manner.

Via a correspondingly projected menu navigation, a desired image can be controlled on a monitor (not shown here) and, in particular, it is possible, for example, to switch to a previous or a subsequent image by tapping on projected arrow keys between the images. Alternatively, an image can also be projected onto the projection surface 15.

The control system 1 is also adapted so that the stereo camera 13 can detect the position and position of the side table 20 and thus the projection surface 15. In this way, the side table 20 at different locations, depending on the needs of the respective operation and other medical devices 22 or number and level of medical personnel 21 within a predetermined range, which the stereo camera 13 can detect positioned. The ECU 18 processes this position data and controls the projector 12 so that the projection 16 of the projector 12 is adapted to / at the selected position of the projection surface 15. In particular, the projection surface 15 is fitted in the border of the side table and also shown so that a distortion is corrected.

Between the projector 12 and the detection device 13 is vertically from the ceiling 4 of the operating room 2 hanging a transparent plate-shaped

Glass pane / glass plate 24 is arranged. This glass plate 24 with its flat and smooth surface is well suited for sterilization. In the variant described above, the projector 12 radiates through the transparent glass pane 24. In this embodiment, however, by applying an electrical

Tension on the glass, a transparency of the glass pane 24 in matt and slightly milky change. This has the effect that the projector 12 throws in a second variant instead of a projection 16 on the side table 20, a projection 16 on one side of the matt and slightly milky glass plate 24. The medical

Operators 21, standing on the other side of the glass 24, can see the graphical user interface very well. A corresponding input by the medical staff 21 is again detected by the detection device 13 and forwarded the detected input to the ECU 18. The ECU 18 thereafter, as described above, a corresponding control command to the interface 19 or to the projector 12 from.

FIG. 3 shows a control system 1 according to the invention of a further preferred embodiment in a perspective view. Here, the control system 1 has a separate control module 25 in which the projector 12, the detection device 13 and the electronic control unit (ECU) 18 are combined with each other. This creates a portable control module 25, which can be positioned or set up at different areas of the medical sterile room. The control module also has a battery. The control module 25 in the geometric shape of a box is attached to a fastener 26 in the form of a metal bar above and spaced from the operating table 10. Alternatively, it is also conceivable to attach the control module 25 to the ceiling 4 of the sterile room 2 (detachable) or, for example, to an already installed ceiling lamp or operating light. The Projector 12 of the control module again has the laser module 14, which on the surgical cover 11 (not shown here) or directly on the patient 9 in the region of the abdomen of the patient 9, the visual projection 16 in the form of a graphic

User interface projected.

The detection device 13 of the control module 25 is again a stereo camera and a photodiode in this embodiment, which also covers an infrared range in addition to the visible region of the light and can detect this. The

Stereo camera 13 can also detect a surface contour 27, here the surgical cover 11 in the abdominal region of the patient 9, which processes the ECU 18. The ECU 18 controls the projector 12 accordingly so that an aligned projection on the surgical cover 11 in the region of the abdomen of the patient 9 arises. The user 21 (not shown here), which can stand to one side of the patient 9, can by means of a hand-held surgical instrument, such as a

Needle holder, which serves as an interaction component 17, make a manual input in the region of the projection 16. Likewise, he can perform an input with his bare hand.

The ECU 18 processes the input of the user 21 detected by the detection device 13, and outputs the detected and interpreted input to the interface 19 as a control command. The interface ^, which is directly connected to the ECU 18, sends via Bluetooth® the interpreted input of the user 21 to other medical devices (not shown) or to the operating table 10, which has a corresponding Bluetooth receiver. Likewise, the ECU 18 is adapted to receive data from the medical equipment 22 or the hall equipment 23 via the interface 19 and display it by means of the projector 12 to the user 21 as a visual projection 16 on the projection surface 15.

Thus, the control module 25 is able to wirelessly interact with different medical devices 22 and / or hall equipment 23. Contamination of the sterile area is effectively prevented by means of the control system 1 according to the invention, since a virtual sterile barrier with a distance between the

Control module 25 and the projection surface 15 is created, which only by is penetrated by electromagnetic radiation. There is no need to provide an additional physical sterile barrier to the unsterile control module 25.
