Description

Technical Field

[0001] This utility model relates to the technical field, specifically to an ultrasonic cannon treatment handpiece with adjustable ultrasonic focusing depth. Background Technology

[0002] Focused ultrasound is a commonly used non-invasive cosmetic technique. The ultrasound cannon uses micro-point focusing and focal zone methods, and utilizes the principle of precise focusing of ultrasonic energy to precisely target the SMAS fascia layer, deep dermis layer and dermis layer, inducing thermal damage areas and promoting collagen regeneration, achieving non-invasive lifting and wrinkle improvement effects.

[0003] However, existing ultrasonic beam devices typically have a fixed focal depth during treatment, requiring operators to change treatment heads to alter the focal depth. This process is time-consuming, cumbersome, and costly. Furthermore, some commercially available ultrasonic devices with adjustable focal depths have complex structures and high manufacturing costs. Utility Model Content

[0004] Technical Objective: To address the shortcomings of existing ultrasound therapy handpieces with adjustable focusing depth, this utility model discloses an ultrasound cannon therapy handpiece with adjustable focusing depth. It achieves axial position adjustment of the cannon head transducer through magnetic drive, enabling precise adjustment of the focusing depth. Simultaneously, it employs a quick-assembly / disassembly structure to simplify the operation process and improve the practicality of the equipment.

[0005] Technical solution: To achieve the above technical objectives, the present invention adopts the following technical solution:

[0006] An ultrasonic cannon therapy handpiece with adjustable ultrasonic focusing depth includes consumables and a handle. The consumables include a cannon head transducer for emitting focused ultrasonic waves. The cannon head transducer is fixedly installed at the front end of a cannon head transducer sealing bracket. The rear end of the cannon head transducer sealing bracket has a cylindrical cavity, and a first strong magnet is installed inside the cylindrical cavity. The cannon head transducer sealing bracket is connected to the consumable housing through a sealing component, which is used to prevent impurities from entering the consumable. The front end of the consumable housing has a consumable outer sealing plate with several hooks. A consumable PCBA is also installed at the front end of the consumable outer sealing plate for electrical connection with the handle.

[0007] The handle includes a linear drive assembly for driving the gun head transducer to move axially. The linear drive assembly is installed inside the handle housing. The front end of the linear drive assembly has a cavity, and a second strong magnet is installed in the cavity. The second strong magnet drives the first strong magnet and the gun head transducer to move axially through magnetic coupling to adjust the focusing depth. The front end of the handle housing has a hand tool outer sealing plate. The hand tool outer sealing plate is provided with a hook groove that cooperates with the hook, which is used to realize the quick connection and disassembly of the consumable part and the handle part. The hand tool outer sealing plate is also provided with a locking structure for controlling the quick assembly and disassembly between the hook and the hook groove.

[0008] The handle also has a control component inside, which includes a main control board installed inside the handle housing and a power button set on the handle housing. The main control board is connected to the drive component and external power supply through wiring to transmit control signals and drive the transducer to work. The main control board is connected to the consumable PCBA through a plug-in interface, which facilitates quick circuit disconnection and reconnection when the consumable is disconnected from the handle.

[0009] Preferably, the linear drive assembly includes an electric cylinder and a gun head rod. The electric cylinder is fixedly installed in a mounting groove inside the handle housing, and the extension rod of the electric cylinder is connected to the rear end of the gun head rod by a thread. The front end of the gun head rod is provided with a cavity for fixing the second strong magnet and ensuring its stable position.

[0010] Preferably, the locking structure includes a locking slider, a return spring, a locking pressure plate, and a locking button. The locking slider is installed at the rear end of the outer cover plate of the hand tool and has a hook groove that mates with the outer cover plate of the consumables. The locking slider is connected to the locking pressure plate through the return spring, which is located between the locking slider and the locking pressure plate to provide a return force. The locking button is located on the upper part of the handle shell. When the locking button is pressed, it pushes the locking slider to squeeze the return spring, thereby separating the hook groove from the hook.

[0011] Preferably, both the outer surface of the hook and the inner surface of the hook groove are provided with a ramp structure to achieve smooth sliding and locking during quick assembly and disassembly.

[0012] Preferably, the cylindrical cavity of the gun head transducer sealing bracket is covered with a gun head bellows cover to protect the first strong magnet and prevent impurities from entering.

[0013] Preferably, the sealing assembly includes a sealing gasket and a gun head sealing cap installed between the gun head transducer sealing bracket and the consumable housing. The sealing gasket is located at the front end of the gun head sealing cap and is axially arranged to form an airtight protection.

[0014] Preferably, the outer shell of the consumable is made of plastic, and an inner shell of the consumable is fixedly installed inside it. The inner shell of the consumable is used to support the sealing bracket of the gun head transducer.

[0015] Preferably, the consumable is also provided with a consumable protective cover, which is a detachable structure used to cover the consumable shell and provide protection during transportation and storage, and can be removed when in use.

[0016] Preferably, the handle housing includes an upper shell and a lower shell, which are connected by screws or snaps to form a closed cavity.

[0017] Preferably, the focusing depth range of the gun head transducer is 2mm~4.5mm, and the adjustment step length is 0.1mm.

[0018] Beneficial effects:

[0019] This invention achieves axial movement of the transducer head through a magnetic component, combined with high-precision displacement control of the linear drive component including an electric cylinder and a head rod. This allows for flexible adjustment of the focusing depth to meet the treatment needs of different skin layers (such as the fascia layer and dermis layer). Compared with existing fixed-depth devices, the adjustment method of this invention is more efficient and precise, improving the treatment effect. Furthermore, the use of magnetic drive instead of the traditional complex mechanical transmission structure reduces the number of mechanical parts and lowers the difficulty of equipment processing and assembly.

[0020] This utility model employs a mechanical design of hooks and hook grooves for the consumable part and the handle part. Combined with the operation of the locking slider, return spring, and locking button, it enables quick connection and disassembly of the consumable part. Users can replace the consumable simply by pressing the locking button, and the connection can be completed without additional tools. This reduces the complexity of operation, significantly reduces installation time, and facilitates maintenance and consumable replacement, greatly improving the efficiency of equipment use and further reducing the overall manufacturing and maintenance costs of the equipment.

[0021] The consumable PCBA of this invention is connected to the main control board of the handle via a plug-in interface, ensuring the stability and reliability of signal transmission and avoiding the contact problems or signal interference that may be caused by traditional cable connections. The plug-in interface design simplifies the circuit connection process and allows users to quickly disconnect and reconnect the circuit when replacing consumables, thus improving the maintainability of the equipment.

[0029] The present invention will be described more clearly and completely below by way of a preferred embodiment in conjunction with the accompanying drawings, but this does not limit the present invention to the scope of the described embodiment.

[0030] like Figure 1 and Figure 2 As shown, an ultrasonic cannon therapy handpiece with adjustable ultrasonic focusing depth includes consumables and a handle. The consumables include a cannon head transducer 3 for emitting focused ultrasonic waves. Figure 1 The diagram shows the shape and path of the focused ultrasonic beam 27 emitted by the cannon head transducer 3. The cannon head transducer 3 is fixedly installed at the front end of the cannon head transducer sealing bracket 4. The rear end of the cannon head transducer sealing bracket 4 is provided with a cylindrical cavity, and a first strong magnet 7 is installed in the cylindrical cavity. The cannon head transducer sealing bracket 4 is connected to the consumable housing 1 through a sealing assembly. The cylindrical cavity of the cannon head transducer sealing bracket 4 is covered with a cannon head bellows cover 8. The sealing assembly and the cannon head bellows cover 8 are used to protect the first strong magnet 7 and prevent impurities from entering.

[0031] The front end of the consumable casing 1 is provided with a consumable outer sealing plate 10, such as Figure 4 As shown, the consumable outer cover plate 10 is provided with several hooks 13, and the front end of the consumable outer cover plate 10 is also equipped with a consumable PCBA9 for electrical connection with the handle.

[0032] The sealing assembly includes a sealing gasket 5 and a gun head sealing cover 6 installed between the gun head transducer sealing bracket 4 and the consumable housing. The sealing gasket 5 is located at the front end of the gun head sealing cover 6 and is axially arranged to form an airtight protection.

[0033] like Figure 3 As shown, the consumable material is structurally composed of the following components from front to back: consumable outer shell 1, consumable inner shell 2, gun head transducer 3, gun head transducer sealing bracket 4, sealing gasket 5, first strong magnet 7, gun head sealing cover 6, gun head bellows cover 8, consumable PCBA 9, and consumable outer sealing plate 10. The cylindrical cavity of the gun head transducer sealing bracket 4 passes through the sealing gasket 5, gun head sealing cover 6, gun head bellows cover 8, consumable PCBA 9, and consumable outer sealing plate 10 in sequence. The gun head transducer 3 emits a focused ultrasonic beam 27 to the consumable inner shell 2 and the consumable outer shell 1.

[0034] The handle includes a linear drive assembly for driving the gun head transducer 3 to move axially. The linear drive assembly is installed inside the handle housing. The handle housing includes an upper shell 23 and a lower shell 24. The upper shell 23 and the lower shell 24 are connected by screws or clips to form a closed cavity. The linear drive assembly, locking structure and control assembly are installed inside the closed cavity.

[0035] The linear drive assembly is disposed in the mounting slot of the lower housing 24. The front end of the linear drive assembly has a cavity, in which a second strong magnet 19 is installed. The second strong magnet 19 drives the first strong magnet 7 and the gun head transducer 3 to move axially through magnetic coupling to adjust the focusing depth. The first strong magnet 7 and the second strong magnet 19 can be strong neodymium magnets. The linear drive assembly includes an electric cylinder 22 and a gun head pull rod 20. The electric cylinder 22 is fixedly installed in the mounting slot inside the lower housing 24 of the handle. The front end of the extension rod 21 of the electric cylinder 22 is provided with a threaded hole, and the rear end of the gun head pull rod 20 is provided with a thread. The extension rod 21 of the electric cylinder 22 is connected to the rear end of the gun head pull rod 20 through the thread. Alternatively, the two can be connected by direct welding. The front end of the gun head pull rod 20 is provided with a cavity for fixing the second strong magnet 19 and ensuring its stable position.

[0036] The handle also has a control component inside, which includes a main control board 25 installed inside the handle housing and a power button 26 set on the handle housing. The main control board 25 is connected to the drive component and external power supply through wiring to transmit control signals and drive the gun head transducer to work. The main control board 25 is connected to the consumable PCBA9 through a plug-in interface, which facilitates quick circuit disconnection and reconnection when the consumable is disconnected from the handle.

[0037] The focusing depth range of the transducer 3 is 2mm to 4.5mm, with an adjustment step length of 0.1mm. The control component controls the extension and retraction of the electric cylinder 22 through a preset program, with each adjustment step length being 0.1mm, thereby precisely adjusting the focusing depth of the transducer 3. The focusing depth is continuously adjustable within the range of 2mm to 4.5mm through the axial movement of the transducer 3. By adjusting the focusing depth of the transducer 3, the focusing depth range of the ultrasonic cannon therapy handpiece is achieved to be 2mm to 4.5mm, with an adjustment step length of 0.1mm.

[0038] This focused depth range covers the needs of multiple treatment areas such as the face and neck. The 2mm depth mainly targets the superficial dermis for skin tightening and wrinkle improvement, while the 4.5mm depth acts on the fascia layer to enhance tissue tightening, especially suitable for facial lifting. At the same time, the 0.1mm step length design allows for precise adjustment of the ultrasound focus according to the needs of different areas and tissue layers, improving the effect while reducing damage to non-tissues.

[0039] The front end of the handle housing is provided with a hand tool outer sealing plate 12. The hand tool outer sealing plate 12 is provided with a hook groove 14 that cooperates with the hook 13, which is used to realize the quick connection and disassembly of the consumable part and the handle part. The hand tool outer sealing plate 12 is also provided with a locking structure, which is used to control the quick assembly and disassembly between the hook 13 and the hook groove 14. The gun head pull rod 20 passes through the hand tool outer sealing plate 12 and can contact the first strong magnet 7 in the consumable.

[0040] like Figure 5 As shown, the locking structure includes a locking slider 15, a return spring 16, a locking pressure plate 17, and a locking button 18. The locking slider 15 is installed at the rear end of the outer cover plate 12 of the hand tool, and has a hook groove 14 that cooperates with the consumable outer cover plate 10. The locking slider 15 is connected to the locking pressure plate 17 through the return spring 16. The return spring 16 is located between the locking slider 15 and the locking pressure plate 17 to provide a reset force. Specifically, the locking pressure plate 17 has a groove corresponding to the shape of the return spring 16. One end of the return spring 16 contacts the bottom end of the groove, and the other end contacts the locking slider 15, thereby achieving compression or reset. The locking button 18 is located on the upper shell 23 of the handle housing, and has a mounting post at its lower end. The mounting post passes through the upper shell 23 of the handle and is connected to the locking slider 15. When the locking button 18 is pressed, it pushes the locking slider 15 to squeeze the return spring 16, thereby separating the hook groove 14 from the hook 13.

[0041] In one embodiment, the outer surface of the hook 13 and the inner surface of the hook groove 14 are both provided with a ramp structure. The angle of the ramp structure can be set to 30° to 45° to achieve smooth sliding and locking during quick assembly and disassembly. The part of the hook 13 that contacts the hook groove 14 is also provided with a groove, which allows the hook 13 to be more securely engaged in the hook groove 14.

[0042] In one embodiment, the consumable outer shell 1 is made of plastic, and a consumable inner shell 2 is fixedly installed inside it. The consumable inner shell 2 is used to support the gun head transducer sealing bracket 4.

[0043] In one embodiment, the consumable is further provided with a consumable protective cover 11, which is a detachable structure used to cover the consumable shell 1 and provide protection during transportation and storage. When in use, the consumable protective cover 11 is removed to connect the consumable to the handle.

[0044] The working principle of this utility model is as follows: The linear drive assembly of the handle part includes an electric cylinder 22 installed inside the lower shell 24 of the handle and a cannon head pull rod 20 threadedly connected to it. When the control assembly of the handle part, including the main control board 25 and the power button 26, receives the user input signal, the main control board 25 controls the extension and retraction of the electric cylinder 22. The extension and retraction of the electric cylinder 22 drives the axial movement of the cannon head pull rod 20. The second strong magnet 19 at the front end of the cannon head pull rod 20 drives the first strong magnet 7 in the cannon head transducer sealing bracket of the consumable part and the cannon head transducer 3 at its front end to move synchronously along the axis through magnetic coupling. The axial change of the position of the cannon head transducer 3 realizes the precise adjustment of the focusing depth to meet the treatment needs of different levels.

[0045] The principle of quick assembly / disassembly and electrical connection:

[0046] The consumable part is mechanically connected to the hook groove 14 of the handle part through the hook 13. After the hook 13 is inserted into the hook groove 14, the locking structure of the handle part, including the locking slider 15, the return spring 16, the locking pressure plate 17 and the locking button 18, securely locks the hook 13 in the hook groove 14.

[0047] When the locking button 18 is pressed, the locking slider 15 slides downward under the action of the locking pressure plate 17, releasing the connection between the hook 13 and the hook groove 14, enabling quick disassembly and replacement of consumable parts. When the locking button 18 is released, the reset spring 16 automatically resets the locking slider 15, ensuring that the normal locking function is restored during subsequent assembly.

[0048] Electrical connection is achieved through the consumable PCBA9 in the consumables section and the main control board 25 in the handle section. The consumable PCBA9 and the main control board 25 are connected through a plug-in interface. Insertion provides power and removal disconnects the signal, ensuring the stability of signal transmission and simplifying the circuit operation for consumable replacement.

[0049] Equipment operation process: The consumable part is inserted into the hook slot 14 of the handle part through the hook 13; the locking structure of the handle part automatically locks the consumable part, and at the same time, the consumable PCBA9 and the main control board 25 are electrically connected through the plug-in interface.

[0050] The user presses the power button 26 on the handle to start the device; the main control board 25 adjusts the extension distance of the electric push cylinder 22 according to the user's needs, and drives the transducer 3 of the cannon head to move axially through the magnetic coupling of the first strong magnet 7 and the second strong magnet 19, thereby adjusting the focusing depth of the ultrasound; after receiving the electrical signal, the transducer of the cannon head emits focused ultrasound waves, which act on the target skin tissue to complete the treatment operation.

[0051] When the user presses the locking button, the locking slider 15 slides down to release the connection between the hook 13 and the hook slot 14; the consumable part is safely disassembled, and the plug-in interface between the consumable PCBA9 and the main control board 25 is automatically disconnected.

[0052] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
