The following describes the implementation of the embodiment of the present application with reference to the drawings.

FIG. 1 is a schematic illustration of an X-ray imaging system according to an embodiment of the application; as shown in FIG. 1, an X-ray imaging system 100 may be an example of a medical imaging system that includes a floor assembly 110 disposed in a scanning room 101, a column (WALL STAND) assembly 120, and a couch assembly 130, and a control assembly 150 disposed within a control room 102. The floor stand 110 comprises a column 111, a support arm structure 112, and an x-ray source assembly 113. The support arm structure 112 is for carrying an X-ray source assembly 113, and the support arm structure 112 is mounted on the column 111.

Although some embodiments of the present application are described based on a floor standing X-ray imaging system, embodiments of the present application are not so limited. For example, the medical imaging system may also be other types of X-ray imaging systems, such as a mobile X-ray imaging system, or the medical imaging system may also be other types of imaging systems, such as an electronic Computer Tomography (CT) system, a Positron Emission Tomography (PET) system, a Magnetic Resonance Imaging (MRI) system, or the like.

For convenience of description, in the present application, the x-axis, the y-axis, and the z-axis are defined as the x-axis and the y-axis being located in a horizontal plane and being perpendicular to each other, and the z-axis is perpendicular to the horizontal plane, specifically, the extending direction of the support arm structure 112 or the width direction of the test bed device is defined as the x-axis, the direction perpendicular to the extending direction of the support arm in the horizontal plane or the length direction of the test bed device is defined as the y-axis direction, the extending direction of the upright post 111 is defined as the z-axis direction, and the z-axis direction is the vertical direction.

The landing gear 110 further includes a guide rail mounted on the floor, the guide rail being disposed along the y-axis direction, and the column 111 being moved along the guide rail, i.e., along the y-axis direction. Furthermore, the support arm structure 112 is also capable of moving in a vertical direction (i.e. the z-axis direction) with respect to the upright 111. In addition, a driving device may be disposed between the X-ray source assembly 113 and the column 111, and the driving device may drive the X-ray source 113 to rotate about the X-axis, and a specific structure of the driving device will be described below.

The X-ray source assembly 113 includes a bulb assembly, a beam limiter 114, and a bulb control device 115. An X-ray tube is disposed within the bulb assembly and is operable to generate X-rays and project the X-rays toward a desired region of interest ROI of a patient.

The beam limiter 114 is typically mounted below the X-ray tube, and X-rays emitted from the X-ray tube are irradiated onto the subject to be detected through an opening of the beam limiter 114. The size of the opening of the beam limiter 114 determines the irradiation range of the X-rays, that is, the area size of the exposure Field of View (FOV). It is well known that X-rays are harmful to the human body, and thus it is necessary to control the X-rays to irradiate only the region to be examined, i.e., the region of interest (Region of Interest, ROI), of the object to be examined.

The bulb control device 115 is mounted on the bulb assembly, and the bulb control device 115 includes a display screen and a user interface such as control buttons for performing preparation work before photographing, such as patient selection, protocol selection, and positioning.

Column assembly 120 includes a first detector assembly 121, column 122, and a connection (not shown). The connecting portion comprises a support arm vertically connected with the height direction of the upright 122 and a rotating bracket mounted on the support arm, the first detector assembly 121 is mounted on the rotating bracket, the upright device 120 further comprises a detector driving device arranged between the rotating bracket and the first detector assembly 121, and the first detector assembly 121 can further rotate relative to the support arm and form a certain angle with the upright under the driving of the detector driving device and along the direction parallel to the height direction of the upright 122 on the plane lifted by the rotating bracket. The first detector assembly 121 has a plate-like structure whose direction is changeable so as to make the X-ray incident surface vertical or horizontal according to the incident direction of the X-rays.

The detection bed device 130 includes a second detector assembly (not shown), and the selection or use of the first detector assembly 121 and the second detector assembly may be determined based on a photographing position and/or a photographing protocol of a patient, or may be determined based on a position of a detected object obtained by photographing with a camera, so as to perform a photographing inspection of a lying position or a standing position. Fig. 1 shows only one example of a column and a test bed, and it should be understood by those skilled in the art that any form or arrangement of columns and/or test beds may be selected and installed, and that the columns and/or test beds are not limiting to the overall solution of the present application.

In some embodiments, the control device 150 may include a source controller and a detector controller. The source controller is used for commanding the X-ray source to emit X-rays for image exposure. The detector controller is used to select an appropriate detector among a plurality of detectors and coordinate control of various detector functions, for example, to automatically select a corresponding detector according to the position or posture of a detected object, or to perform various signal processing and filtering functions, in particular, initial adjustment of a dynamic range, interleaving of digital image data, and the like. In some embodiments, the control device 150 may provide power and timing signals for controlling the operation of the X-ray source and detector.

In some embodiments, the control device 150 may also be configured to reconstruct one or more desired images and/or determine useful diagnostic information corresponding to the patient using the digitized signals, wherein the control device 150 may include one or more special purpose processors, graphics processing units, digital signal processors, microcomputers, microcontrollers, application Specific Integrated Circuits (ASICs), field Programmable Gate Arrays (FPGAs), or other suitable processing devices.

Of course, the medical imaging system may also include other numbers or configurations or forms of control devices, e.g., the control devices may be local (e.g., co-located with one or more X-ray imaging systems 100, e.g., within the same facility and/or the same local network); in other implementations, the control device may be remote and therefore only accessible via a remote connection (e.g., via the internet or other available remote access technology). In particular implementations, the control device may also be configured in a cloud-like manner and may be accessed and/or used in a manner substantially similar to the manner in which other cloud-based systems are accessed and used.

The system 100 also includes a memory device (not shown) in which the processor can store the digitized signals. For example, the memory may include a hard disk drive, a floppy disk drive, an optical disk read/write drive, a digital versatile disk drive, a flash memory drive, and/or solid state memory. The memory may also be integrated with the processor to efficiently use the footprint and/or to meet desired imaging requirements.

The system 100 further comprises an input device 160, which input device 160 may comprise some form of operator interface such as a keyboard, a mouse, a voice activated control device, a touch screen (which may also be referred to as a display device as described below), a trackball or any other suitable input device, through which an operator may input operating/control signals to the control device.

The system 100 further comprises a display device 151 (e.g. a touch screen or display screen), which display device 151 may be used to display a list of detected objects, a positioning or exposure setting of detected objects, an image of detected objects, etc. an operation interface.

In the X-ray imaging system shown in fig. 1, the floor standing device 110 includes the following motions: the upright post moves along the length direction (X-axis) of the detection bed, the support arm drives the X-ray source component to move along the vertical direction (z-axis), the X-ray source component rotates around the axis where the support arm is located, and the like.

For example, for the movement of the X-ray source assembly 113 about the axis of the support arm 111, a driving device is generally disposed between the X-ray source assembly and the column, and the original driving device is generally disposed separately from the support arm 111, that is, in the original support arm structure, it is generally required to install the driving device at another position parallel to the support arm for driving the rotation of the X-ray source assembly, or it is required to dispose the driving device between the end of the support arm and the X-ray source assembly, so that the total volume of the whole support arm structure and the driving device is larger, the structure is complex, the distance between the column and the X-ray source assembly is increased, and the rigidity requirement for the cantilever is further increased, which results in the overall cost and the maintenance difficulty being larger.

To solve the above-mentioned problems, or at least similar problems, embodiments of the present application provide a support arm structure and a medical device.

The following describes embodiments of the present application in detail.

The embodiment of the application provides a support arm structure with more compact structural design. FIG. 2 is a schematic view of an X-ray imaging system with a support arm structure mounted thereon in accordance with an embodiment of the present application; as shown in fig. 2, the X-ray imaging system has a column 111, a support arm structure 112, an X-ray source assembly 113, and a couch apparatus 130. One end of the support arm structure 112 is mounted on the upright 111, the other end is connected to the X-ray source assembly 113, and the support arm structure 112 and the X-ray source assembly 113 are suspended above the couch device 130. Further, as shown in fig. 2, the X-ray source assembly 113 can be rotated about the X-axis, thereby enabling a wider range of examinations.

FIG. 3 is a schematic diagram of a support arm structure 112 according to an embodiment of the present application; as shown in fig. 3, the support arm structure 112 provided in the embodiment of the present application includes: the first support arm 10 and the drive device 20.

As shown in fig. 2 and 3, one end of the first support arm 10, i.e., the a end as shown in fig. 3, is connected to the X-ray source assembly 113, the other end of the first support arm 10, i.e., the B end as shown in fig. 3, is fixedly mounted on the column 111, and the first support arm 10 extends in a direction perpendicular to the column 111, i.e., in the X-axis direction as shown in fig. 2. A drive device 20 is mounted within the first support arm 10, and the drive device 20 is capable of driving the X-ray source assembly 113 in motion. In the above embodiment, as shown in fig. 3, the inside of the first support arm 10 has a hollow structure, and a driving device capable of driving the X-ray source assembly 113 to move is installed in the hollow structure of the first support arm 10, so that the driving device 20 can be completely hidden inside the first support arm 10.

The structure of the driving device accommodated in the first support arm 10 will be described below.

Fig. 4 is a schematic view of the driving device 20 of the support arm structure 112 according to the embodiment of the present application; as shown in fig. 3 and 4, the drive device 20 has a tube shaft holder 21 and a drive assembly, wherein the drive assembly includes a brake 22, a clutch 23, and a motor 24.

The tube shaft holder 21 has a rotation shaft 211, the rotation shaft 211 having a first axis x. One end (i.e., the a-end) of the tube shaft support 21 is connected to the X-ray source assembly 113, and the other end is connected to the brake 22.

The brake 22 is connected to the clutch 23 and the motor 24, the clutch 23 and the motor 24 are used for driving the rotation of the X-ray source unit 113, and the brake 22 is used for braking the rotation of the X-ray source unit 113.

The X-ray source assembly 113 is rotatable about the first axis X by the driving device 20.

By the structure of the driving device 20, the rotation motion of the X-ray source assembly 113 can be controlled by a simple structure, and the volume and weight of the support arm structure 112 can be further reduced.

In some embodiments, as shown in fig. 4, the driving assembly of the driving device 20 may further include: a coupler 25 that is provided between the brake 22 and the clutch 23 and couples both; an encoder 26 that encodes the rotation angle of the X-ray source assembly 113.

In the above embodiment, the coupler 25 couples the rotation shaft 211 of the tube shaft holder 21 with the rotation shafts of the clutch 23 and the motor 24 so as to rotate together about the first axis x, and the stopper 22 mounted at the other end of the tube shaft holder 21 can brake the rotation movement, by which the total length of the driving device 20 can be shortened, and thus the problem that the structural size of the support arm needs to be enlarged to accommodate a longer driving device can be avoided.

However, the above-described configuration is merely an example, and the same effect can be obtained by attaching a hollow encoder to the main shaft of the driving device 20, and the present application is not limited thereto.

In the above embodiment, the tube shaft bracket 21 is mounted and fixed to the end of the first support arm 10, and is held relatively stationary with respect to the first support arm 10. One end of the tube shaft support 21 is connected to the X-ray source assembly 113, and the X-ray source assembly 113 can rotate about the first axis X under the driving of the driving device 20, and the brake 22 of the driving device 20 can brake the rotation.

Through the above structure, the driving device 20 is completely accommodated in the first support arm 10, and the hidden design can avoid the complex design of parallel arrangement of the support arm and the driving device between the upright 111 and the X-ray source assembly 113, so that the whole support arm structure 112 is more compact and miniaturized, which is more convenient for the operation of medical staff and is more beneficial for later maintenance and repair.

In some embodiments, the support arm structure 112 is also designed as a telescopic structure, i.e. a linear movement of the support arm structure 112 in the direction of the first axis x. Fig. 5 is a schematic view of the telescopic arm of the support arm structure 112 according to an embodiment of the present application, and fig. 6 is a side sectional view of the telescopic arm of the support arm structure 112 according to an embodiment of the present application.

As shown in fig. 5 and 6, the support arm structure 112 provided in the embodiment of the present application further has a second support arm 30, the second support arm 30 has a hollow structure, and a track 31 is provided in the hollow structure, and the first support 10 is sleeved in the hollow structure of the second support arm 30 and mounted on the track 31, whereby the first support arm 10 can be extended and retracted with respect to the second support arm 30.

Fig. 7 is a schematic view of an X-ray imaging system of a telescopic arm mounted with a support arm structure 112 according to an embodiment of the present application, as shown in fig. 7, unlike in the above-described embodiment, in the telescopic support arm structure 112, one end of the second support arm 30 is fixedly mounted on the column 111 and is held perpendicular to the column 111, by which the support arm structure 112 can be telescopic in the extending direction of the first axis X-axis and further drive the X-ray source assembly 113 to be telescopic.

The structure between the first support arm 10, the driving device 20 and the X-ray source assembly 113 is the same as that of the previous embodiment, and a description thereof will not be repeated here.

In the above described embodiments, the drive means 20 may also be arranged to provide a driving force for a lateral movement of the support arm structure 112 and/or a rotational movement of the X-ray source assembly 113. In an embodiment of the present application, the driving device 20 may drive one of the above motions. For example, the driving device 20 drives the X-ray source assembly 113 to rotate along the first axis X, and the lateral telescopic movement of the support arm structure 112 can be in a manual mode. In practice, the lateral movement of the support arm structure 112, i.e., telescoping, is primarily suitable for emergency or patients who are not prone to operating tables, but this occurs in a relatively low proportion, and therefore, manual mode is typically employed to control the lateral movement of the support arm. In contrast, rotation of the X-ray source assembly 113 is an operation requiring high frequency use, and thus requires a motorized mode to ensure accuracy of its angular position and to provide advanced functions such as automatic positioning, image stitching, etc.

In addition, according to different usage frequencies and usage scenarios, different motions of the X-ray imaging system may switch different modes, in the above embodiment, the driving device 20 may provide driving force for the extension and retraction of the support arm structure 112 and the rotation of the X-ray source assembly 113, and may also switch the extension and retraction motion of the support arm structure 112 to a manual mode as required, for example, the application is not limited thereto, and by switching the flashlight mode as required, energy consumption of the extension and retraction arm structure may be saved and applied to a plurality of different medical scenarios.

According to the configuration described in the above embodiment, after the X-ray source unit 113 is connected, the entire driving device 20 is hidden in the first support arm 10, and only the cable (not shown) of the X-ray source unit 113 can be seen from the outside.

In addition, in the existing X-ray imaging system, since the mechanical structure of the support arm is too complex, the arm is large in size, and interference is easily generated between the support arm and the cable of the X-ray source assembly 113, according to the compact and miniaturized telescopic arm structure provided by the embodiment of the application, interference with the cable of the X-ray source assembly 113 can be avoided, and further, cable regulation of the X-ray imaging system in a use process is facilitated.

In the above embodiment, according to the support arm structure provided by the embodiment of the application, through the unique hidden design of the driving device, all components can be ensured to be kept in a compact size, so that the support arm can be light and miniaturized, thereby improving the safety of the telescopic arm structure when the telescopic arm structure is hung above a patient, and simultaneously, the operation of medical staff is simpler and more convenient.

In addition, since the telescopic arm structure provided by the embodiment of the application provides switching between the manual mode and the electric mode, the flexibility of operation is improved, and since the total weight of the support arm structure is lighter and the arm size is smaller, the operation can be very convenient even in the manual mode.

Next, the inside of the telescopic structure of the support arm structure 112 according to the embodiment of the present application will be described in detail.

Returning to fig. 5 and 6, as shown in fig. 5 and 6, in the hollow structure of the second support arm 30, that is, in the inner wall of the second support arm 30, a rail 31 is provided, and the first support arm 10 is mounted on the rail 31, whereby the first support arm 10 can slidably expand and contract in the extending direction of the first axis x with respect to the second support arm 30.

In order to ensure the safety of the support arm structure 112, the first support arm 10 slides within the range of the safety distance, and the second support arm 30 is further provided with a braking device 32 and a limiting device 33 inside.

FIG. 8 is another schematic view of a telescoping arm of the support arm structure 112 of an embodiment of the present application; as shown in fig. 8, the braking device 32 of the support arm structure 112 has a protrusion 32-1 that expands and contracts with the first support arm 10 and a blocking plate 32-2 that is fixed inside the second support arm 30 to remain relatively stationary with the second support arm 30, and the protrusion 32-1 comes into contact with the blocking plate 32-2 during the extension of the first support arm 10 in a direction away from the second support arm 30, thereby braking the first support arm 10.

The detent 32 also limits the position in which the first support arm 10 extends when it slides relative to the second support arm 30.

As shown in fig. 6 and 8, a limiting device 33 is further disposed beside the track 31, and is mainly used for limiting the sliding range of the first support arm 10 retracted into the second support arm 30, and during the retraction of the first support arm 10 toward the direction approaching the second support arm 30, the edge of the first support arm 10 contacts with the limiting device 103, thereby limiting the first support arm 10.

In the above embodiment, the structure and the arrangement position of the braking device 32 are only examples, and other braking structures may be used to brake the first support arm 10 in the embodiment of the present application, and specific reference may be made to related art in the field, which is not repeated herein.

In the above embodiment, the position of the limiting device 33 can be adjusted as required, so as to expand or reduce the telescopic position range of the first support arm 10, which is not specifically shown in the present application.

It should be noted that, as shown in fig. 6 and 8, at the bottom end of the second support arm 30, a circuit board 40 is further provided, and since the rail 31 has the maximum telescopic range, the telescopic range of the first support arm 10 should be at least between a position not exceeding the maximum stroke of the rail 31 and a position not interfering with the circuit 40 and its components, the specific position depending on the rigidity of the second support arm 30, which can be adjusted as needed, which is not limited by the present application.

In some embodiments, as shown in fig. 6, the support arm structure 112 further includes a position feedback structure 50 that is capable of defining and feeding back the relative positions of the first support arm 10 and the second support arm 30.

FIG. 9 is a schematic illustration of a position feedback structure 50 of a telescoping arm structure according to an embodiment of the present application; for example, as shown in fig. 9, the position feedback structure 50 includes: a ball plunger 51 provided on an outer wall of the first support arm 10; and a groove 52 provided on an inner wall of the second support arm 30.

The ball plunger 51 and the socket 52 can cooperate to maintain the relative positions of the first support arm 10 and the second support arm 30.

Specifically, the ball plunger 51 is mounted on one outer side surface of the first support arm 10, a stopper plate having a groove 52 is mounted on an inner side surface of the second support arm 30 facing the outer side surface, a rotatable ball is provided on the ball plunger 51, and the ball plunger 51 is fitted to a position where the groove 52 is provided, that is, the ball plunger 51 can be extended and contracted together with the first support arm 10 when the first support arm 10 is extended and contracted, and is engaged with the groove 52 at a position where the groove 52 is provided.
