Description

Technical Field

[0001] This invention relates to the field of medical devices, and more specifically, to a feedback shockwave therapy handpiece. Background Technology

[0002] Extracorporeal shock wave therapy (ESWB), a non-invasive treatment method, has been widely used in orthopedics, rehabilitation medicine, and sports medicine in recent years. Its core principle is to utilize high-energy sound waves generated by electrohydraulic, piezoelectric, or electromagnetic effects, which are transmitted to human tissues through a treatment handpiece. This releases adhesions, promotes angiogenesis, and blocks pain signal transmission, and is commonly used to treat chronic soft tissue injuries such as plantar fasciitis, calcific tendinitis, and tennis elbow.

[0003] A typical shockwave therapy handpiece usually consists of a handpiece body, an energy transmission mechanism, and a replaceable treatment head. During treatment, the operator holds the handpiece and places the treatment head against the skin surface of the patient's pain point. Using a coupling agent as a medium, the shockwave energy is precisely delivered to the deep lesion tissue.

[0004] However, when using existing shockwave therapy handpieces, the treatment head of the handpiece is in continuous close contact with the patient's treatment area, and the high-frequency vibration causes continuous friction between the treatment head and the skin. This can easily raise the skin temperature at the treatment site, causing discomfort such as burning and stinging, which affects the patient's treatment experience and reduces the practicality of the treatment handpiece.

[0005] Therefore, we made improvements and proposed a feedback shockwave therapy handpiece. Summary of the Invention

[0006] The purpose of this invention is to address the problem that existing shockwave therapy handpieces, when in use, suffer from continuous close contact between the treatment head and the patient's treatment area, and the high-frequency vibration causes continuous friction between the treatment head and the skin, which easily leads to increased skin temperature at the treatment site, causing discomfort such as burning and stinging, affecting the patient's treatment experience and reducing the practicality of the treatment handpiece.

[0007] To achieve the above-mentioned objectives, the present invention provides a feedback shockwave therapy handpiece to improve the aforementioned problems.

[0008] The application is as follows:

[0009] A feedback shockwave therapy handpiece includes a control unit, a shockwave generating and conducting unit, and a treatment unit, assembled sequentially from top to bottom.

The two electromagnetic coils are electrically connected to a controller in the control unit. The treatment unit has a transmission block and a treatment block in its middle, with the opposite ends of the transmission block and treatment block in contact. The transmission block is opposite to the opening of the conduit.

[0010] The conduit has a protrusion in the middle, and a movable cavity is adapted to be opened in the protrusion. The two electromagnetic coils are respectively located at the upper and lower ends of the protrusion. The cone has a circular plate in the middle. A set of vertical air guide grooves are opened in an annular shape at equal intervals on the side of the conduit at the bottom of the protrusion. A set of first air guide holes opposite to the air guide grooves are opened in an annular shape at equal intervals in the middle of the transfer block. A second air guide hole connected to the first air guide hole is opened in an annular shape at equal intervals on the treatment block.

[0011] As a preferred technical solution of this application, the electromagnetic coil includes a coil support, and a top ring and a bottom ring are respectively installed at the upper and lower ends of the conduit. One electromagnetic coil is installed between the top ring and the protrusion, and the other electromagnetic coil is installed between the bottom ring and the protrusion. The top ring is provided with a second through groove for the electromagnetic coil wire to pass through and a set of second ventilation grooves.

[0012] As a preferred technical solution of this application, the top of the cone is located inside the conduit above the protrusion and is opposite to the electromagnetic coil located above it.

[0013] As a preferred technical solution of this application, the treatment unit further includes a connecting seat, which is threadedly connected to the bottom of the housing, and an annular transition groove is provided in the middle of the transmission block, with the top opening of the first air guide hole located in the annular transition groove.

[0014] As a preferred technical solution of this application, a first adjustment port is provided on the side of the protrusion along its circumferential direction, a sealing tube is rotatably sleeved on the outside of the protrusion, a second adjustment port corresponding to the first adjustment port is provided on the side of the sealing tube, an operating tube is rotatably sleeved on the outer wall of the housing, a connecting rod fixed on the operating tube and fixed to the sealing tube, and a trajectory groove for the connecting rod to move is provided on the housing.

[0015] As a preferred technical solution of this application, the bottom of the protrusion has a convex ring, the top of the protrusion has a limiting ring, the sealing tube is rotatably installed between the convex ring and the limiting ring, and sealing rings are installed at both ends of the sealing tube between the limiting ring and the convex ring respectively.

[0016] As a preferred technical solution of this application, the top of the housing has a limiting protrusion, the operating tube is installed between the connecting seat and the limiting protrusion, and a rubber pad is installed between the top end of the operating tube and the limiting protrusion.

[0017] As a preferred technical solution of this application, the side of the operating tube is provided with an installation hole for installing the connecting rod, and the side of the sealing tube is fixed with an installation groove corresponding to the installation hole.

[0018] As a preferred technical solution of this application, the upper coil bracket has a first through groove on its side for the bottom electromagnetic coil wire to pass through, and both coil brackets have a set of first ventilation grooves equidistantly arranged in a ring on their sides.

[0019] As a preferred technical solution of this application, a clamping ring is also installed at the top opening of the conduit. The bottom of the clamping ring has a cylindrical part opposite to the top opening of the conduit, and a set of connecting slots are equidistantly opened on the side of the clamping ring in an annular shape.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] In the scheme of this application:

[0022] 1. Through the movable cavity set on the catheter and the circular plate on the cone, as the cone moves from top to bottom, the circular plate moves synchronously downward with the cone within the movable cavity, thereby compressing and driving the air at the bottom of the movable cavity (below the circular plate). This air flows sequentially through multiple air guide channels, the first air guide hole, and the second air guide hole, and is finally directed towards the patient's treatment site. As the cone drives the circular plate to return to its original position, a negative pressure is formed within the movable cavity due to the increased volume. Through the air guide channels, the first air guide hole, and the second air guide hole, the airflow is drawn back into the cavity from the patient's treatment site. Through this periodic airflow circulation mechanism, the burning and stabbing pain experienced by the patient during treatment is significantly reduced.

[0023] 2. A sealing tube is rotatably installed on the protrusion, and a first adjustment port is opened on the protrusion. A second adjustment port corresponding to the first adjustment port is opened on the sealing tube. By controlling the rotation of the sealing tube, the overlapping area of ​​the first and second adjustment ports can be controlled, thereby adjusting the airflow discharge. When the circular plate reciprocates with the cone in the movable cavity, part of the airflow can be discharged into the housing through the overlapping first and second adjustment ports, thereby reducing the airflow from the air guide groove, the first air guide hole and the second air guide hole, reducing the airflow impact force blown from the second air guide hole to the patient's treatment site, reducing the irritation caused by the airflow, and the airflow discharged into the housing from the first and second adjustment ports can be used for heat dissipation of the two electromagnetic coils, improving energy utilization efficiency.

[0042] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0043] The present invention will be further described below with reference to embodiments.

[0044] Example: Please refer to Figures 1 to 7As shown, a feedback shockwave therapy handpiece includes a control unit 100, a shockwave generating and conducting unit 200, and a treatment unit 300, assembled sequentially from top to bottom. The shockwave generating and conducting unit 200 includes a cylindrical housing 201. A conduit 202 is fixedly installed in the middle of the inner cavity of the housing 201. A cone 203 is slidably installed inside the conduit 202. Electromagnetic coils 204 are respectively installed at the upper and lower ends of the inner cavity of the housing 201. The two electromagnetic coils 204 are electrically connected to the controller in the control unit 100. The treatment unit 300 has a transmission block 301 and a treatment block 302 in the middle. The transmission block 301 and the treatment block 302 are positioned relative to each other. The two ends are in contact, with the transmission block 301 facing the opening of the catheter 202. During operation, the two electromagnetic coils 204 are alternately energized. The top electromagnetic coil 204 generates electromagnetic force through pulsed current to drive the cone 203 to move upward and return to the upper position of the catheter 202. The bottom electromagnetic coil 204 generates electromagnetic force through pulsed current to drive the cone 203 to move downward at high speed to strike the treatment part 300. This achieves the electromagnetic force to push the cone 203 to reciprocate along the inner lumen of the catheter 202. When the cone 203 reciprocates vertically, it strikes the transmission block 301 and the treatment block 302 to transfer energy, thereby generating a divergent shock wave source.

[0045] In order to solve the problem that in the prior art, when the treatment head of the shockwave therapy handpiece is in continuous close contact with the patient's treatment position, and the high-frequency vibration characteristics cause continuous friction between the treatment head and the skin, which easily leads to an increase in the skin temperature at the treatment site and causes discomfort such as burning and stinging, the catheter 202 and the cone 203 are improved in this embodiment.

[0046] Specifically, the conduit 202 has a protrusion 2021 in the middle, and a movable cavity 2022 is adapted to be opened in the protrusion 2021. Two electromagnetic coils 204 are respectively located at the upper and lower ends of the protrusion 2021. The cone 203 has a circular plate 2031 in the middle. The side of the conduit 202 located at the bottom of the protrusion 2021 has a set of vertical air guide grooves 2023 in an annular shape at equal intervals. The middle of the transmission block 301 has a set of first air guide holes 3011 in an annular shape at equal intervals, which are opposite to the air guide grooves 2023. The treatment block 302 has a second air guide hole 3021 in an annular shape at equal intervals, which is connected to the first air guide hole 3011.

[0047] Through the movable cavity 2022 set on the conduit 202 and the circular plate 2031 on the cone 203, as the cone 203 moves from top to bottom, the circular plate 2031 moves synchronously downward with the cone 203 within the movable cavity 2022, thereby compressing and driving the air at the bottom of the movable cavity 2022 (below the circular plate 2031), causing it to flow sequentially through multiple air guide channels 2023, the first air guide hole 3011, and the second air guide hole 3021, and finally directed towards the patient's treatment position 300. During the process of the cone 203 driving the circular plate 2031 to return to its original position upward, the movable cavity 2022 forms a negative pressure due to the increase in volume. Through the air guide channels 2023, the first air guide hole 3011, and the second air guide hole 3021, the airflow is drawn back into the cavity from the patient's treatment position 300. Through this periodic airflow circulation mechanism, the burning and stabbing pain of the patient during treatment is significantly reduced.

[0048] Preferably, the electromagnetic coil 204 includes a coil support 2041, which is adapted to the inner wall of the housing 201. The upper and lower ends of the conduit 202 are respectively equipped with a top ring 2024 and a bottom ring 2026. One electromagnetic coil 204 is installed between the top ring 2024 and the protrusion 2021, and the other electromagnetic coil 204 is installed between the bottom ring 2026 and the protrusion 2021. The top ring 2024 is provided with a second wire groove 2025 for the electromagnetic coil 204 wire to pass through and a set of second ventilation grooves 2028.

[0049] Preferably, the top of the cone 203 is located inside the conduit 202 above the protrusion 2021 and opposite to the electromagnetic coil 204 located above, so that after the bottom of the cone 203 hits the transmission block 301, the electromagnetic coil 204 above generates electromagnetic force through pulse current to drive the cone 203 to move upward back to the upper position of the conduit 202.

[0050] Preferably, the treatment unit 300 further includes a connecting seat 303, which is threadedly connected to the bottom of the housing 201 to facilitate the disassembly and replacement of the treatment head. The middle part of the transfer block 301 is provided with an annular transition groove 3012, and the top opening of the first air guide hole 3011 is located in the annular transition groove 3012. Through the transition of the annular transition groove 3012, the first air guide hole 3011 located in the annular transition groove 3012 is always connected with the air guide channel 2023 to guide the airflow.

[0051] Preferably, a first adjustment port 2027 is provided on the side of the protrusion 2021 along its circumferential direction, a sealing tube 205 is rotatably sleeved on the outside of the protrusion 2021, a second adjustment port 2051 corresponding to the first adjustment port 2027 is provided on the side of the sealing tube 205, an operating tube 206 is rotatably sleeved on the outer wall of the housing 201, a connecting rod 2061 fixed on the operating tube 206 and fixed to the sealing tube 205, and a trajectory groove 2011 for the connecting rod 2061 to move is provided on the housing 201;

[0052] In specific implementation, by rotating the operating tube 206, the operating tube 206 drives the sealing tube 205 to rotate synchronously through the connecting rod 2061; during this rotation, by controlling the overlapping area of ​​the first adjustment port 2027 and the second adjustment port 2051, the airflow discharge volume is adjusted. The advantage of this design is that when the circular plate 2031 moves back and forth with the cone 203 in the movable cavity 2022, part of the airflow can be discharged into the housing 201 through the overlapping first adjustment port 2027 and the second adjustment port 2051, thereby reducing the airflow from the air guide groove 2023, the first air guide hole 3011 and the second air guide hole 3021.

[0053] The diversion and pressure relief mechanism effectively reduces the airflow impact force from the second air guide hole 3021 to the patient treatment unit 300, reducing the irritation caused by the airflow, thus adapting to different patients and further improving the patient's treatment comfort; and the airflow discharged into the housing 201 from the first adjustment port 2027 and the second adjustment port 2051 can be used for heat dissipation of the two electromagnetic coils 204, improving energy utilization efficiency and further enhancing the practicality of the device.

[0054] Preferably, the bottom of the protrusion 2021 has a protruding ring 2052, and the top of the protrusion 2021 has a limiting ring 2053. The sealing tube 205 is rotatably installed between the protruding ring 2052 and the limiting ring 2053, thereby realizing the rotation of the sealing tube 205 on the protrusion 2021. The two ends of the sealing tube 205 are respectively installed with sealing rings 2054 between the limiting ring 2053 and the protruding ring 2052, which improves the sealing performance of the connection between the sealing tube 205 and the protrusion 2021 and avoids the probability of leakage of the compressed airflow from the connection between the sealing tube 205 and the protrusion 2021 when the first adjustment port 2027 and the second adjustment port 2051 are misaligned. This makes the airflow blown from the second air guide hole 3021 to the patient treatment section 300 more concentrated.

[0055] Preferably, the top of the housing 201 has a limiting protrusion 2012, which limits the top end of the operating tube 206. The operating tube 206 is installed between the connecting seat 303 and the limiting protrusion 2012. The connecting seat 303 limits the bottom end of the operating tube 206, thereby achieving the purpose of rotating the operating tube 206 on the housing 201. A rubber pad 2013 is installed between the top end of the operating tube 206 and the limiting protrusion 2012 to increase the friction between the operating tube 206 and the limiting protrusion 2012.

[0056] Specifically, since the connecting seat 303 is threaded to the bottom of the housing 201, when it is necessary to rotate the operating tube 206, simply rotate the connecting seat 303 downwards by 1 to 2 turns to separate the connecting seat 303 from the bottom end of the operating tube 206, thus releasing the constraint on the operating tube 206. Correspondingly, when the connecting seat 303 and the bottom end of the operating tube 206 are in close contact, the constraint on the operating tube 206 is prevented from affecting the airflow guidance by rotating the operating tube 206 under normal use.

[0057] Preferably, the side of the operating tube 206 is provided with an installation hole 2062 for mounting the connecting rod 2061, and the side of the sealing tube 205 is fixed with an installation groove 2056 corresponding to the installation hole 2062. The connecting rod 2061 is installed from the side of the housing 201 to connect the operating tube 206 and the sealing tube 205 into one unit, which facilitates the disassembly and replacement of various components inside the housing 201.

[0058] Preferably, the upper coil support 2041 has a first wire groove 2042 on its side for the wires of the bottom electromagnetic coil 204 to pass through. Both coil supports 2041 have a set of first ventilation grooves 2043 on their sides in an annular shape. The airflow that enters the housing 201 through the first adjustment port 2027 and the second adjustment port 2051 dissipates heat from the two electromagnetic coils 204 through the two sets of first ventilation grooves 2043.

[0059] Preferably, a clamping ring 207 is also installed at the top opening of the conduit 202. The bottom of the clamping ring 207 has a cylindrical part 2071 opposite to the top opening of the conduit 202. Preferably, the clamping ring 207 is threaded to the conduit 202. The cylindrical part 2071 closes the top opening of the conduit 202, so that the cone 203 moves axially back and forth in the conduit 202. The side of the clamping ring 207 is provided with a set of connecting slots 2072 at equal intervals in an annular shape, which facilitates the airflow diverted at the sealing tube 205 to flow toward the top of the housing 201, and facilitates the wires of the two electromagnetic coils 204 to pass through the connecting slots 2072 and be electrically connected to the controller in the control unit 100.
