Abstract

The utility model discloses a handheld impact gun of an impact wave therapeutic instrument, relates to medical instruments, and provides the scheme aiming at the problem that the impact wave output power depends on program adjustment in the prior art. A sealing plate is arranged on the side, away from the piston, of the high-pressure cavity. A push-pull rod which transversely penetrates through the sealing plate is arranged on the sealing plate; one end of the push-pull rod in the high-pressure cavity is fixedly connected with one end of a reset spring; the other end of the reset spring is fixedly connected with the side wall of the piston far away from the compression cavity; the side wall of the push-pull rod is in sliding airtight connection with the sealing plate; a bolt seat is arranged at the tail end of the gun body; and one end of the screw rod is relatively rotatably connected with the free end of the push-pull rod, and the other end of the screw rod extends out of the gun body and then is fixedly connected with a knob. The device has the advantage that the relative position of the piston in the air cavity is indirectly adjusted by rotating the knob outside the gun. Therefore, when the control host outputs the same power to the handheld impact gun, impact waves output by compressed air of the compression cavity can obtain different output powers.

Description

Technical Field

[0001] This utility model relates to medical devices, and more particularly to a handheld shock gun for a shockwave therapy device. Background Technology

[0002] Shockwave therapy devices use a control unit to output high-power compressed gas to a handheld shock gun, which then uses a piston and other mechanisms to convert the energy into shock waves that are delivered to the body from the gun head. The required output power for different individuals or different parts of the same body will not be exactly the same. Changing the output power requires readjusting the control unit's program, which is very time-consuming and inconvenient for medical staff, especially in departments with multiple patients or patients requiring treatment of multiple areas. Utility Model Content

[0003] The purpose of this invention is to provide a handheld shock gun for a shockwave therapy device to solve the problems existing in the prior art.

[0004] The handheld shock gun of the shockwave therapy device described in this utility model includes a gun body and a handle fixedly connected to the end of the gun body; the gun body is provided with an air chamber, which is divided into a high-pressure chamber and a compression chamber by a built-in piston; the compression chamber is close to the gun head and communicates with the muzzle, and is used to output shockwaves to the patient; the high-pressure chamber is away from the gun head and is communicated with the control host through an air tube; a return spring for resetting the piston is provided in the high-pressure chamber;

[0005] The high-pressure chamber is provided with a sealing plate on the side away from the piston; the sealing plate is provided with a horizontally penetrating push-pull rod; one end of the push-pull rod located inside the high-pressure chamber is fixedly connected to one end of a return spring, and the other end of the return spring is fixedly connected to the side wall of the piston away from the compression chamber; the side wall of the push-pull rod is slidably and airtightly connected to the sealing plate.

[0006] The gun body has a bolt seat at its end; the bolt seat is arranged coaxially with the push-pull rod; a screw is provided and threadedly connected to the bolt seat, one end of the screw is rotatably connected to the free end of the push-pull rod, and the other end of the screw extends out of the gun body and is fixedly connected to a knob.

[0007] The compression chamber is connected to the control host via a medicine tube.

[0008] Inside the gun body, a support plate is provided between the sealing plate and the bolt seat to support the screw; the support plate is fixedly connected to the inner wall of the gun body.

[0009] The handheld shock gun of the shockwave therapy device described in this utility model has the advantage that the relative position of the piston in the air chamber can be indirectly adjusted by rotating a knob outside the gun. This allows the shockwave output from the compressed air in the compression chamber to achieve different output powers when the control host outputs the same power to the handheld shock gun, avoiding frequent adjustments to the control host's program and simplifying the medical operation process.

[0016] like Figures 1 to 2 As shown, the handheld shock gun of the shockwave therapy device of this utility model includes a gun body 11 and a handle 12 fixedly connected to the end of the gun body 11; the gun body 11 is provided with an air chamber, which is divided into a high-pressure chamber 14 and a compression chamber 13 by a built-in piston 21; the compression chamber 13 is close to the gun head of the gun body 11 and communicates with the muzzle, and is used to output shockwaves to the patient; the high-pressure chamber 14 is away from the gun head and is communicated with the control host through an air pipe 18; the high-pressure chamber 14 is provided with a return spring 23 for resetting the piston 21.

[0017] The high-pressure chamber 14 is provided with a sealing plate 15 on the side away from the piston 21; the sealing plate 15 is provided with a horizontally penetrating push-pull rod 22; one end of the push-pull rod 22 located in the high-pressure chamber 14 is fixedly connected to one end of a return spring 23, and the other end of the return spring 23 is fixedly connected to the side wall of the piston 21 away from the compression chamber 13; the side wall of the push-pull rod 22 is slidably and airtightly connected to the sealing plate 15.

[0018] The gun body 11 has a bolt seat 17 at its end; the bolt seat 17 is coaxially arranged with the push-pull rod 22; a screw 32 is threadedly connected to the bolt seat 17, one end of the screw 32 is rotatably connected to the free end of the push-pull rod 22, and the other end of the screw 32 extends out of the gun body 11 and is fixedly connected to a knob 31.

[0019] The working principle of the handheld shock gun of the shockwave therapy device described in this utility model is as follows: When medical staff need to adjust the shockwave output power, they do not need to adjust the program of the control host; they only need to rotate the knob 31. With the cooperation of the bolt seat 17 and the screw 32, the push-pull rod 22 is pushed forward or pulled out horizontally, thereby adjusting the relative position of the piston 21 in the natural state of the return spring 23. Specifically, when the push-pull rod 22 is pulled out of the high-pressure chamber 14, the compression chamber 13 gains more space, and the output shockwave power relatively increases. Conversely, when the push-pull rod 22 is pushed forward of the high-pressure chamber 14, the initial space of the compression chamber 13 is compressed, and the output shockwave power relatively decreases. After the control host compresses the gas with a constant output power to the high-pressure chamber 14, the piston 21 will push different volumes of gas outward, thereby achieving the final adjustment of the shockwave output power.

[0020] The compression chamber 13 is connected to the control unit via the drug tube 19. The purpose is to provide a specific drug delivery method that allows sprayed or other drugs to be delivered to the human body via shock waves.

[0021] Inside the gun body 11, a support plate 16 is provided between the sealing plate 15 and the bolt seat 17 to support the screw 32; the support plate 16 is fixedly connected to the inner wall of the gun body 11. The purpose is to improve overall rigidity and durability.

[0022] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this utility model.
