Description

Ultrasonic therapeutic head and ultrasonic therapeutic apparatus

Technical Field

The utility model relates to the technical field of medical equipment, in particular to an ultrasonic treatment head and an ultrasonic treatment instrument.

Background

Ultrasonic therapeutic equipment is a therapeutic equipment which can generate high heat by focusing ultrasonic waves on subcutaneous fat layer, destroy subcutaneous fat cells and play a role in reducing fat. The ultrasonic therapeutic apparatus converts the electric energy into acoustic energy through the transducer; in order for the acoustic energy emitted by the transducer to be accurately focused, the transducer needs to be immersed in the liquid, and therefore a sealed housing is required in which the transducer and the liquid are sealed; the shell is provided with an acoustic port through which ultrasonic waves emitted by the transducer are emitted. When in use, the sound-transmitting opening is clung to the skin, so that the ultrasonic waves are focused on the subcutaneous fat layer; on the other hand, in order to realize sealing, an acoustic membrane needs to be arranged to cover the acoustic port, and the acoustic membrane is directly adhered to the skin when in use. If the sound-transmitting membrane is not adhered to the skin, focusing failure is caused, the focusing point may be too shallow, so that skin cells of a dermis layer are damaged, and normal tissues of a human body are damaged. In order to ensure that the sound-transmitting membrane is tightly attached to the skin, a pressure sensor is usually required to sense whether the sound-transmitting membrane is tightly attached to the skin; because the acoustically transparent film needs to remain flat to conform to the skin surface, a sensor is typically disposed between the acoustically transparent film and the housing; the strength of the bond of the acoustically transparent film to the housing is reduced by the arrangement of the sensor. In general, the sound-transmitting membrane is fixed to the housing by adhesion, and if the sensor is located at the adhesion surface, the adhesion strength may be low, so that the sound-transmitting membrane falls off in use and the liquid leaks, thereby damaging the ultrasonic treatment head. The ultrasound therapy head, which places the transducer between the acoustically transparent membrane and the housing, is therefore generally of a short life.

The utility model provides an ultrasonic treatment head.

In an embodiment of the present utility model, referring to fig. 1 and 2, the ultrasonic treatment head includes: a housing 10, the housing 10 including a main portion 11 and a movable portion 12, the movable portion 12 being movably connected with the main portion 11;

an inner shell 20, wherein the inner shell 20 is arranged in the outer shell 10, the inner shell 20 is connected with the movable part 12, the inner shell 20 is provided with a sound-transmitting opening 21, the movable part 12 is provided with an opening for exposing the sound-transmitting opening 21 outside the outer shell 10;

a sensor 70, the sensor 70 being disposed within the outer housing 10 and on a side of the inner housing 20 facing away from the sound-transmitting opening 21;

when the movable part 12 moves axially inwards towards the outer shell 10, the inner shell 20 is driven to move, and the inner shell 20 and the outer shell 10 are made to approach each other, so that the inner shell 20 or the outer shell 10 presses against the sensor 70.

The movable link may be a socket, for example, the main portion 11 is sleeved on the outer side of the movable portion 12, so that the main portion 11 and the movable portion 12 can slide relatively, meanwhile, a hook is disposed on the main portion 11, a clamping groove is disposed on the movable portion 12, and the movable range of the hook in the clamping groove is limited, so that the movable range of the movable portion 12 relative to the main portion 11 can be limited. A spring may be provided between the main portion 11 and the movable portion 12, the spring being in a compressed state and pressing the main portion 11 and the movable portion 12 so that the main portion 11 and the movable portion 12 have a tendency to separate from each other, so that the shape of the housing 10 is kept stable at this time. The interior of the inner housing 20 may be configured as a liquid containing chamber in which the transducer 60 is mounted, the liquid containing chamber being filled with a liquid that is impedance matched to the transducer 60 to ensure proper operation of the transducer 60. The sound-transmitting port 21 is used for transmitting ultrasonic waves generated by the transducer 60 out of the inner housing 20 and eventually focusing on the subcutaneous fat layer. The sound-transmitting opening 21 is covered with a sound-transmitting film, and the sound-transmitting film is made of a material favorable for transmitting ultrasonic waves, so that the inner shell 20 can form a closed cavity to prevent liquid from leaking while transmitting the acoustic waves. Conventional ultrasound therapy heads typically mount the transducer 70 between the acoustically transparent membrane and the inner housing 20 such that pressure generated when the acoustically transparent membrane is in close proximity to the skin triggers the transducer 70 so that the user knows that the acoustically transparent membrane has been in close proximity to the skin and can begin generating ultrasound for therapy. However, such a structure results in a lower strength of connection of the sound-transmitting membrane to the inner housing 20, and thus easily causes the sound-transmitting membrane to fall off in use, resulting in damage to the ultrasonic treatment head. In the scheme of the utility model, the sensor 70 is arranged in the outer shell 10 at one side of the inner shell 20 away from the sound transmission port 21, so that the influence of the installation of the sensor 70 on the installation of the sound transmission membrane is avoided, the installation of the sound transmission membrane is firmer, and the service life of the ultrasonic treatment head is prolonged. The sensor 70 may be a pressure sensor 70 that indicates that the acoustically transparent film is in close proximity to the skin when the pressure is above a predetermined value. The sensor 70 can be fixed on the inner shell 20 and moves together with the inner shell 20, so that the inner wall of the outer shell 10 is finally pressed against the sensor 70; the sensor 70 may also be fixed to the outer housing 10, with the inner housing 20 moving and eventually abutting the sensor 70.

Referring to fig. 1 and 2, further, the ultrasonic treatment head further includes an elastic member 30, and the main portion 11 and the movable portion 12 are connected by the elastic member 30. The elastic member 30 connects the main portion 11 and the movable portion 12 to have a capability of moving the main portion 11 and the movable portion 12 with each other, that is, to enable the movable portion 12 to be movably connected to the main portion 11. The elastic member 30 may have a ring shape, and both sides in the axial direction of the housing 10 are connected to the movable portion 12 and the main portion 11, respectively, such that when the movable portion 12 and the main portion 11 have a relative movement tendency in the axial direction of the housing 10, the elastic member 30 is compressed or stretched to allow the movement to occur. In addition, when the movable portion 12 is not subjected to a force, the initial positional relationship between the movable portion 12 and the main portion 11 can be restored by the elastic force of the elastic member 30 itself, even if the movable portion 12 is restored.

Referring to fig. 1 and 2, the elastic member 30 is optionally configured as a silicone material. The silica gel has good ageing resistance and elasticity, and can prolong the service life of the ultrasonic treatment head. The elastic member 30 may be made of rubber, which is inexpensive and contributes to cost reduction.

Referring to fig. 1 and 2, alternatively, where the main portion 11 is connected to the movable portion 12, the main portion 11 surrounds the movable portion 12, and the elastic member 30 is connected to the main portion 11 at a radially outward side of the housing 10; the elastic member 30 is connected to the movable portion 12 at a radially inward side of the housing 10. Thus, when the movable portion 12 and the main portion 11 move in the axial direction of the housing 10, the elastic member 30 is subjected to shearing force, thereby allowing a relative movement tendency between the movable portion 12 and the main portion 11. This allows the choice of an elastic material with a greater young's modulus to limit the movement of the mobile part 12 in the radial direction of the casing 10; to ensure the movement of the movable portion 12 in the axial direction of the housing 10, the width of the elastic member 30 in the radial direction of the housing 10 may be increased.

Referring to fig. 1 and 2, alternatively, the elastic member 30 is configured as a light-transmitting material, and the ultrasound therapy head further includes an annular lamp 40, where the annular lamp 40 is disposed around the inner housing 20, and the annular lamp 40 is used to irradiate the direction of the sound-transmitting opening 21 through the elastic material. The ring light 40 is provided to illuminate the patient's skin to allow the user to see the patient's skin surface to confirm the treatment location, and to emit light of a specific wavelength to stimulate the patient's skin to recover. The light-transmitting material can be transparent silica gel or transparent polyurethane.

Referring to fig. 1 and 2, alternatively, an abutment ring 50 is provided between the main portion 11 and the movable portion 12, the abutment ring 50 abutting against the movable portion 12 on the radially inward side of the housing 10, and the abutment ring 50 abutting against the main portion 11 on the radially outward side of the housing 10. The abutment ring 50 may be made of a non-elastic material, such as a hard plastic or wood. Since the abutment ring 50 abuts the movable portion 12 and the main portion 11 on both sides in the radial direction of the housing 10, respectively, the movement of the interaction portion in the radial direction of the housing 10 can be restricted. To trigger the sensor 70, the movable portion 12 is required to have the ability to move in the axial direction of the housing 10, and the less the movement in the other direction, the more advantageous the stability of the movement of the movable portion 12, so restricting the movement of the movable portion 12 in the radial direction of the housing 10 can improve the stability of the movable portion 12. When the interaction has a movement in the radial direction of the housing 10, friction may also be generated to the sensor 70, damaging the sensor 70. When the abutment ring 50 is used in combination with the annular lamp 40, the abutment ring 50 may be made of a light-transmitting material, such as glass or transparent plastic, or a light-homogenizing material, which is a conventional hard material and is not described herein.

Referring to fig. 1 and 2, the sensor 70 is optionally configured as a micro switch. The specific structure of the micro switch belongs to the prior art and is not described in detail here. The trigger stroke of the micro switch is small, so that the movable part 12 can trigger the micro switch only by a small stroke. The ultrasound therapy head may be configured such that the transducer 70, once triggered, begins to generate ultrasound waves to enhance the efficiency of the therapy; the sensor 70 may also be configured to prompt the user that the sound-transmitting membrane is pressed against the skin by means of a change in color or intensity of light or other prompt means after being triggered, and generate ultrasonic waves after the user confirms the sound-transmitting membrane so as to facilitate the control of the user.

Referring to fig. 1 and 2, alternatively, the micro switch is configured as a micro switch having self-resetting capability. Thus, when the user stops moving the ultrasonic treatment head away from the skin surface, the movable part 12 is reset, the micro switch is reset, that is, the micro switch is stopped to be triggered, the ultrasonic treatment head can be set to stop releasing ultrasonic waves once the micro switch is stopped to be triggered, so that energy is saved, and meanwhile, the working time of the ultrasonic treatment head can be shortened, so that the service life of the ultrasonic treatment head is prolonged. The micro switch can also be configured as a micro switch without automatic resetting capability, and only the two sides of the micro switch are respectively fixed with the outer shell 10 and the inner shell 20, so that when the outer shell 10 and the inner shell 20 are separated, the micro switch can be stretched to stop triggering the micro switch; when the outer case 10 and the inner case 20 are brought close together, the micro switch is compressed to trigger the micro switch.

Referring to fig. 1 and 2, optionally, a limit post 22 is provided on the inner housing 20, the limit post 22 being configured to abut the outer housing 10 when the inner housing 20 abuts and triggers the sensor 70 to block further approaching of the inner housing 20 to the outer housing 10. To avoid excessive compression of the skin by the user, which may result in excessive pressure on the movable portion 12, such that the sensor 70 may be damaged by the excessive pressure, the stopper 22 may be provided to ensure that the sensor 70 is not subjected to excessive pressure. The stopper post 22 may be fixed to the inner case 20 and extend toward the outer case 10 in the axial direction of the outer case 10. When the movable portion 12 is reset, the distance between the end of the limit post 22 away from the inner housing 20 and the outer housing 10 may be set to be equal to the stroke required to trigger the sensor 70, so as to avoid the excessive stroke of the movable portion 12 and crush the sensor 70. The stop post 22 may also be disposed on the outer shell 10, where the stop post 22 extends axially along the outer shell 10 toward the inner shell 20.

Referring to fig. 1, optionally, a spring is provided between the side of the inner housing 20 facing away from the sound-transmitting opening 21 and the outer housing 10, the spring being in a compressed state. Thus, the spring can push the inner shell 20 and drive the movable part 12, so that the movable part 12 can reset by itself to stop squeezing the micro switch, and the micro switch is stopped to be triggered. Thus, when the user stops pressing the skin, the movable portion 12 is automatically reset, and the micro switch stops being triggered, so that the transducer 60 can be controlled to stop emitting ultrasound, thereby saving power. In addition, the spring can be independently fixed between the inner shell and the outer shell, and also can be sleeved on the limit post.

The utility model also provides an ultrasonic therapeutic apparatus, which comprises an ultrasonic therapeutic head, and the specific structure of the ultrasonic therapeutic head refers to the above embodiments, and because the ultrasonic therapeutic apparatus adopts all the technical schemes of all the embodiments, the ultrasonic therapeutic apparatus at least has all the beneficial effects brought by the technical schemes of the embodiments, and the description is omitted herein. The ultrasonic therapeutic apparatus can be connected with the ultrasonic therapeutic head through the interface of the ultrasonic therapeutic head so as to supply power to the ultrasonic therapeutic head and control the ultrasonic therapeutic head to complete the treatment.

The foregoing description is only of the preferred embodiments of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structural changes made by the description of the present utility model and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the utility model.
