Abstract
Description
Technical Field
[0001] This invention relates to the field of health and wellness therapy or healthcare technology, and more specifically, to a shockwave therapy device and its control method. Background Technology
[0002] Shockwave therapy is a non-invasive physical therapy device that utilizes physically focused high-energy sound waves coupled with a water bag to deliver gentle physical energy. Through stress effects, cavitation effects, and metabolic activation, it conditions muscles, bones, and soft tissues. The device relieves muscle and fascia tension, optimizes local microcirculation, and activates the body's metabolism and self-repair capabilities. It is widely applicable to various health and wellness scenarios, including daily body care, post-exercise relaxation, and overall physical conditioning.
[0003] Currently, existing shockwave therapy devices have the following shortcomings in use: They lack an effective soft impact mechanism, resulting in significant pain for users. Traditional devices use compressed gas to drive lightweight projectiles to impact the treatment head at high speed, generating steep peak pressure pulses with a rise time of approximately 3-5 microseconds. While this sharp impact waveform has concentrated energy, it causes intense stinging sensations in the skin and superficial tissues, leading to decreased user compliance. This is especially problematic for pain-sensitive individuals or those requiring multiple high-intensity treatments in deeper areas, resulting in a poor experience. Furthermore, the coupling agent cannot be gradually released during treatment. Existing technologies require a single application of the coupling agent before treatment, leading to a large initial dosage and waste. As the shockwave continues to act, the coupling agent gradually dries due to vibration, bubble formation, or moisture evaporation, causing acoustic impedance mismatch and energy attenuation. Operators often need to interrupt treatment to manually reapply the agent, affecting treatment continuity and making it difficult to ensure the uniformity and stability of the coupling layer thickness.
[0004] It should be noted that the word "treatment" in the name of shockwave therapy device is a common description used in the industry. It is only used to refer to the conditioning, soothing and repair of the human body through physical energy. It does not refer to the diagnosis, symptomatic treatment or pathological intervention of various diseases, and does not involve disease-related diagnosis and treatment. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this invention provides a shockwave therapy device and its control method, solving the following problems: Existing shockwave therapy devices lack an effective soft impact mechanism, resulting in significant pain for users. Traditional devices use compressed gas to drive lightweight projectiles to impact the treatment head at high speed, generating steep peak pressure pulses with a rise time of approximately 3-5 microseconds. While this sharp impact waveform has concentrated energy, it causes intense stinging sensations in the skin and superficial tissues, leading to decreased user compliance. This is especially problematic for pain-sensitive individuals or those requiring multiple high-intensity treatments in deeper areas, resulting in a poor experience. Furthermore, the coupling agent cannot be gradually released during treatment. Existing technologies require a single application of the coupling agent before treatment, leading to large initial usage and waste. As the shockwave continues to act, the coupling agent gradually dries due to vibration, bubble formation, or moisture evaporation, causing acoustic impedance mismatch and energy attenuation. Operators often need to interrupt treatment to manually reapply the agent, affecting treatment continuity and making it difficult to ensure the uniformity and stability of the coupling layer thickness. The present invention is achieved through the following technical solution.
[0006] This invention discloses a shockwave therapy device, comprising a body, an air inlet head mounted on one side of the body, a ballistic guide tube fixedly connected to one end of the air inlet head, a handle housing mounted at the bottom end of the ballistic guide tube, a treatment head movably mounted at the bottom end of the handle housing, a buffer cylinder mounted inside the handle housing, an impact pin guide tube fixedly connected to the inner side of the buffer cylinder, a guide seat fixedly connected to the bottom end of the buffer cylinder, an impact pin movably inserted into the inner side of the impact pin guide tube, and a plurality of pins mounted on the outer surface of the guide seat. A linkage stop assembly is rotatably connected to the inner side of several pins. The linkage stop assembly includes a first link rotatably connected to the inner side of multiple grooves. A second link is rotatably connected to one side of each of the first links. A linkage disc is rotatably connected to one end of each of the second links. A piston reset assembly is installed on the inner side of the handle housing. A snap ring is fixedly connected to the upper end of the treatment head. A liquid storage chamber is installed on the inner side of the handle housing. A release assembly is provided on the inner side of the liquid storage chamber. A primary buffer assembly is provided on the inner side of the buffer cylinder.
[0007] Preferably, a control panel is mounted on the upper surface of the handle housing.
[0008] Preferably, the impact pin guide tube and the guide seat are interlocked, and the impact pin passes through the impact pin guide tube and abuts against the linkage disc.
[0009] Preferably, all of the first links are engaged with the snap ring.
[0010] Preferably, the primary buffer assembly includes a buffer piston movably disposed inside the buffer cylinder, and a buffer sealing end cap is installed at the upper end of the buffer cylinder, wherein the buffer piston slides against the buffer sealing end cap.
[0011] Preferably, a limiting seal ring is fixedly fitted on the outer surface of the impact pin guide tube, and the limiting seal ring abuts against the buffer cylinder.
[0012] Preferably, the piston reset assembly includes a separation base fixedly connected to the inside of the handle housing, the separation base engaging with the liquid reservoir, and the treatment head being movably interleaved with the separation base.
[0013] Preferably, multiple sleeves are fixedly installed in a ring around the outer side of the separating chassis. A push rod is movably arranged inside each of the multiple sleeves. Multiple pressure blocks that abut against the push rods are fixedly connected to the outer surface of the linkage plate. Abutting plates are welded to the inside of each of the multiple push rods located in the sleeves. A return spring is provided inside each of the multiple sleeves. The push rods and return springs are interposed, and the abutting plates abut against the return springs.
[0014] Preferably, a pressure plate is slidably disposed on the inner side of the liquid storage cavity, and multiple pressure rods are fixedly connected to the pressure plate. The pressure plate is fixedly fitted on the outer surface of the treatment head. The release assembly includes a release mesh gasket disposed at the bottom end of the handle housing. The release mesh gasket is fitted on the outer surface of the treatment head and abuts against the liquid storage cavity.
[0015] Preferably, the shockwave therapy device method specifically includes the following steps: S1: The operator first reliably connects the ballistic guide tube to the air inlet head, confirms that the air supply line is unobstructed, and sets the impact parameters through the control panel, including the impact frequency adjustable from 1 to 20 Hz, the output energy level, and the corresponding driving air pressure of 0.2 to 0.6 MPa. Depending on the user's discomfort area, such as plantar fascia, rotator cuff tendon, etc., and the degree of pain sensitivity, the operator selects whether to enable the "soft impact mode". After confirming that a small amount of coupling agent has been initially applied between the treatment head and the skin, the operator starts the device. S2: Then the compressed gas enters the ballistic guide tube through the gas inlet head, pushing the impact pin forward at high speed. The impact pin first hits the buffer piston in the first-stage buffer assembly. The buffer piston compresses the inert gas in the buffer cylinder. This process absorbs about 30%-50% of the initial kinetic energy at the moment of impact, extending the rise time of the originally steep pressure pulse to 12-15 microseconds, achieving the first "peak reduction" buffer, effectively reducing the impact vibration transmitted to the handle and the initial stinging pain felt by the user. S3: After the impact pin passes through the guide seat, it abuts against the bottom of the linkage plate, pushing the linkage plate to move downward. The linkage plate pulls the first linkage through multiple second linkages to rotate synchronously around the pin on the guide seat. When the linkage plate pushes the locking ring to extend the treatment head to the preset end point of the stroke, the ends of multiple first linkages simultaneously abut against the inner wall of the treatment head, mechanically stopping the locking ring. At this time, the remaining impact kinetic energy is distributed to multiple sets of linkages and the stopping mechanism. The treatment head obtains a wide pulse output with a gentle rise and a peak pressure reduction of more than 50%, which acts on the user's uncomfortable area to achieve "soft impact" low-pain treatment. S4: As the linkage plate moves downward, multiple pressure blocks fixed on the linkage plate simultaneously press the corresponding push rods. The push rods move downward, driving the compression spring in the sleeve of the contact plate. At the same time, the pressure plate fixed at the lower end of the push rod slides downward in the liquid storage cavity, gradually squeezing out the pre-filled medical coupling agent in the cavity through the micropores of the release mesh gasket. The squeezed-out coupling agent evenly penetrates along the outer surface of the treatment head to the end face in contact with the skin, automatically replenishing the coupling layer lost due to impact vibration or evaporation, ensuring stable acoustic impedance matching, and avoiding energy attenuation. S5: After one impact, the return spring releases its elastic potential energy, pushing the contact plate and the push rod upward to reset. The push rod pushes the linkage plate upward through the pressure block, causing the second link to unfold and the first link to open and release the locking ring. At the same time, the pressure plate moves upward with the push rod, causing the treatment head to retract to its initial position. During the upward movement of the linkage plate, the impact pin is also pushed backward to reset. Thus, a complete impact-release-reset cycle ends. The device automatically repeats steps S2 to S5 at a preset frequency to achieve continuous low-pain impact treatment. Each impact releases a small amount of coupling agent simultaneously, and the entire process does not require manual interruption for reapplication.
[0016] The beneficial effects of this invention are: 1. In a shockwave therapy device and its control method of the present invention, a multi-stage soft impact mechanical structure is formed by setting a primary buffer component and a linkage interception component, which realizes effective reshaping of the shockwave waveform. Specifically, the impact pin first compresses the inert gas in the buffer cylinder for primary buffering, absorbing about 30%-50% of the initial kinetic energy, extending the steep pressure pulse rise time from the traditional 3-5 microseconds to 12-15 microseconds. Then, through the linkage of the linkage plate, the second linkage and the first linkage, the remaining kinetic energy is distributed to multiple linkage mechanisms, so that the treatment head obtains a wide pulse output with a smooth rise and a peak pressure reduction of more than 50%. This structure transforms the traditional sharp "stabbing" impact into a comfortable "pressing" impact from a physical level, significantly reducing the user's pain and improving treatment compliance. It is especially suitable for the treatment of pain-sensitive areas such as plantar fasciitis and Achilles tendinitis.
[0017] 2. In the shockwave therapy device and its control method of the present invention, by mechanically linking the shock transmission mechanism with the coupling agent release system, the coupling agent is gradually released on demand during the shock process. Specifically, when the linkage plate moves downward, it drives the pressure block to press the top rod synchronously. The top rod drives the top pressure plate to slide in the liquid storage cavity, and the coupling agent is evenly squeezed out through the micropores of the release mesh gasket and penetrates into the skin contact end along the outer surface of the treatment head. This design realizes precise on-demand replenishment of "one shock, one squeeze", avoiding the waste caused by the traditional one-time application before treatment (the amount can be saved by about 60%). At the same time, it solves the problems of coupling layer drying, acoustic impedance mismatch and energy attenuation caused by shock vibration, bubble generation or water evaporation during the treatment process, ensuring that the shock energy acts on the user's uncomfortable parts efficiently and stably throughout the entire process.
[0018] 3. In the shockwave therapy device and its control method of the present invention, by setting a piston reset assembly and a reset spring, the automatic reset of each mechanism and the back absorption management of the coupling agent are realized after the shock is completed. Specifically, the reset spring releases elastic potential energy to push the top rod and the top pressure plate to reset upward, while driving the linkage plate to rise and the connecting rod stop assembly to open and release the treatment head. In the high-frequency shock mode (≥15Hz), the rapid upward movement of the top pressure plate can generate an instantaneous negative pressure in the reservoir, which will back absorb the excess coupling agent at the release mesh gasket, effectively preventing the coupling agent from splashing due to inertia, keeping the end of the treatment head clean, and improving the operating experience and clinical hygiene conditions.
[0019] 4. In the shockwave therapy device and its control method of the present invention, the synergistic effect of the multi-level buffer mechanism and the automatic coupling agent replenishment system significantly improves the continuity of treatment and the convenience of operation. During the entire treatment process, the operator does not need to interrupt the shock to manually replenish the coupling agent, and the treatment time can be shortened by about 30%. At the same time, the first-level buffer component effectively absorbs the initial recoil energy of the shock needle, suppresses the vibration of the handle housing, makes the energy output more stable, and significantly reduces the operator's hand fatigue.

[0024] To address the shortcomings of existing technologies, this invention provides a shockwave therapy device and its control method, solving the following problems: Existing shockwave therapy devices lack an effective soft impact mechanism, resulting in significant pain for users. Traditional devices use compressed gas to drive lightweight projectiles to impact the treatment head at high speed, generating steep peak pressure pulses with a rise time of approximately 3-5 microseconds. While this sharp impact waveform has concentrated energy, it causes intense stinging sensations in the skin and superficial tissues, leading to decreased user compliance. This is especially problematic for pain-sensitive individuals or those requiring multiple high-intensity treatments in deeper areas, resulting in a poor experience. Furthermore, the coupling agent cannot be gradually released during treatment. Existing technologies require a single application of the coupling agent before treatment, leading to large initial usage and waste. As the shockwave continues to act, the coupling agent gradually dries due to vibration, bubble formation, or moisture evaporation, causing acoustic impedance mismatch and energy attenuation. Operators often need to interrupt treatment to manually reapply the agent, affecting treatment continuity and making it difficult to ensure the uniformity and stability of the coupling layer thickness. To more clearly illustrate the technical solutions in the embodiments of the invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.
[0025] Combined with appendix Figure 1-8 A shockwave therapy device includes a body 3. An air inlet head 6 is mounted on one side of the body 3. One end of the air inlet head 6 is fixedly connected to a ballistic guide tube 2. A handle housing 1 is mounted at the bottom end of the ballistic guide tube 2. A treatment head 8 is movably mounted at the bottom end of the handle housing 1. A buffer cylinder 10 is mounted inside the handle housing 1. An impact pin guide tube 15 is fixedly connected to the inside of the buffer cylinder 10. A guide seat 16 is fixedly connected to the bottom end of the buffer cylinder 10. An impact pin 26 is movably inserted into the inside of the impact pin guide tube 15. A connecting rod stop assembly 551 is rotatably connected to the outer surface of the guide seat 16 via multiple pins. The rod-stopping assembly 551 includes a first connecting rod 12 and a second connecting rod 21. One end of the first connecting rod 12 is rotatably connected to the inner side of the groove of the guide seat 16, and the other end of the first connecting rod 12 is rotatably connected to one end of the second connecting rod 21. The other ends of multiple second connecting rods 21 are rotatably connected to a linkage disc 20. A retaining ring 19 is fixedly connected to the upper end of the treatment head 8. A liquid storage chamber 11 is installed on the inner side of the handle housing 1. A release assembly 553 is provided at the bottom end of the liquid storage chamber 11. The release assembly 553 includes a release mesh gasket 7, which is sleeved on the outer surface of the treatment head 8 and abuts against and communicates with the liquid storage chamber 11. A piston reset assembly 552 is also installed inside the handle housing 1. The piston reset assembly 552 includes a separation base 27 fixedly connected to the inside of the handle housing 1. The separation base 27 abuts against the liquid storage chamber 11. The treatment head 8 is movably disposed between the treatment head 8 and the separation base 27. Multiple sleeves 18 are fixedly and circumferentially disposed on the outer side of the separation base 27. A push rod 13 is movably disposed inside each sleeve 18. The part of the push rod 13 located inside the sleeve 18 is welded with an abutment plate 23. A reset spring 24 is disposed inside the sleeve 18. The reset spring 24 is sleeved on the push rod 13, with one end abutting against the abutment plate 23 and the other end against the inner wall of the sleeve 18. The inner side of the reservoir 11 is slidably provided with a pressure plate 22, and the lower ends of multiple push rods 13 are fixedly connected to the pressure plate 22. The pressure plate 22 is fixedly fitted on the outer surface of the treatment head 8. Multiple pressure blocks 17 corresponding to the upper ends of the push rods 13 are fixedly connected to the outer surface of the linkage plate 20. The inner side of the buffer cylinder 10 is provided with a primary buffer assembly 554. The primary buffer assembly 554 includes a buffer piston 25 movably disposed inside the buffer cylinder 10 and a buffer sealing end cap 9 fixedly installed on the upper end of the buffer cylinder 10. The buffer piston 25 and the buffer sealing end cap 9 slide against each other. The buffer cylinder 10 is sealed with inert gas.
[0026] To achieve the above technical solution, the operator connects the ballistic guide tube 2 to the gas inlet head 6, sets the impact frequency and energy level through the control panel 4, and after starting the equipment, the compressed gas drives the impact pin 26 to move at high speed.
[0027] The impact pin 26 first strikes the buffer piston 25, causing the buffer piston 25 to compress the inert gas in the buffer cylinder 10, achieving primary buffering, absorbing about 30%-40% of the initial kinetic energy, and reducing the pressure peak. Subsequently, the impact pin 26 passes through the guide seat 16 and abuts against the lower end face of the linkage plate 20, pushing the linkage plate 20 to move downward. The linkage plate 20 pulls the first linkage 12 to rotate around the pin on the guide seat 16 via the second linkage 21. When the linkage plate 20 pushes the retaining ring 19 to extend the treatment head 8 downward to the predetermined end of the stroke, the free ends of multiple first linkages 12 simultaneously abut against the inner wall of the treatment head 8, mechanically stopping the retaining ring 19. At this time, the remaining impact kinetic energy is distributed to multiple linkage assemblies, and the treatment head 8 obtains a wide pulse with a smooth rise and significantly reduced peak pressure, achieving "soft impact". At the same time as the linkage plate 20 moves downward, the pressure block 17 simultaneously presses the upper end of the top rod 13, and the top rod 13 moves downward, driving the contact plate 23 to compress the return spring 24. The lower end of the push rod 13 drives the pressure plate 22 to slide downward in the liquid storage chamber 11, squeezing out the medical coupling agent in the liquid storage chamber 11. The coupling agent seeps out evenly through the micropores of the release mesh gasket 7 and flows along the outer surface of the treatment head 8 to the end that contacts the skin, automatically replenishing the coupling layer. After one impact, the return spring 24 releases its elastic potential energy, pushing the contact plate 23 and the push rod 13 to return upward. The push rod 13 pushes the linkage plate 20 to rise through the pressure block 17, the second connecting rod 21 unfolds, the first connecting rod 12 opens the release locking ring 19, and the pressure plate 22 moves upward with the push rod 13, causing the treatment head 8 to retract and return. At the same time, the linkage plate 20 rises and pushes the impact pin 26 to return backward, thus completing one impact-release-reset cycle. The device automatically repeats the above steps at a preset frequency.
[0028] A further technical solution is that the reset spring 24 adopts a variable stiffness spring, whose stiffness increases nonlinearly with the increase of compression. When the equipment is working in high-frequency impact mode, such as when the impact frequency is ≥15Hz, the reset spring 24 rebounds faster, and the push rod 13 moves upward quickly, so that the top pressure plate 22 generates an instantaneous negative pressure in the liquid storage chamber 11. This negative pressure can draw back the excess coupling agent at the release mesh gasket 7 into the liquid storage chamber 11, effectively preventing the coupling agent from splashing due to inertia under high-frequency impact, and at the same time avoiding excessive liquid accumulation at the end of the treatment head 8 from affecting the operating field of vision.
[0029] In addition, an adjustable flow orifice is provided between the buffer piston 25 and the buffer cylinder 10 in the primary buffer assembly 554. The opening size of the throttling orifice can be adjusted through the control panel 4, thereby changing the damping characteristics when the inert gas is compressed. When a "gentler" impact waveform is needed, such as when treating pain-sensitive areas such as the soles of the feet and palms, the damping of the throttling orifice is increased to make the buffering effect stronger. When deeper penetration is needed, such as when treating thick muscle groups such as the buttocks and waist, the damping is reduced to retain more impact energy. This embodiment further improves the clinical adaptability and operational cleanliness of the equipment through adjustable buffering and back-suction anti-splash functions.
[0030] A further technical solution involves using a multi-layered hydrophilic microporous material for the release mesh gasket 7, with a micropore diameter of 0.1mm-0.3mm. This material generates a capillary effect when the coupling agent is extruded, allowing the coupling agent to spread more evenly on the end face of the treatment head 8. Simultaneously, a liquid level sensor is installed in the reservoir 11. When the remaining amount of coupling agent is lower than the set threshold, the control panel 4 will issue a prompt sound or light alarm to remind the operator to replenish the coupling agent.
[0031] This invention also provides a shockwave therapy device, the specific operation method of which includes the following steps: S1: The operator first reliably connects the ballistic guide tube 2 to the air inlet head 6, confirms that the air supply line is unobstructed, and sets the impact parameters through the control panel 4, including the impact frequency adjustable from 1 to 20 Hz, the output energy level, and the corresponding driving air pressure of 0.2 to 0.6 MPa. Depending on the user's discomfort area, such as plantar fascia, rotator cuff tendon, etc., and the degree of pain sensitivity, the operator selects whether to enable the "soft impact mode". After confirming that a small amount of coupling agent has been initially applied between the treatment head 8 and the skin, the operator starts the device. S2: Then the compressed gas enters the ballistic guide tube 2 through the gas inlet head 6, pushing the impact pin 26 forward at high speed. The impact pin 26 first hits the buffer piston 25 in the first-stage buffer assembly 554. The buffer piston 25 compresses the inert gas in the buffer cylinder 10. This process absorbs about 30%-50% of the initial kinetic energy at the moment of impact, extending the rise time of the originally steep pressure pulse to 12-15 microseconds, achieving the first "peak reduction" buffer, effectively reducing the impact vibration transmitted to the handle and the initial stinging pain felt by the user. S3: After the impact pin 26 passes through the guide seat 16, it abuts against the bottom of the linkage plate 20, pushing the linkage plate 20 to move downward. The linkage plate 20 pulls the first linkage 12 to rotate synchronously around the pin on the guide seat 16 through multiple second linkages 21. When the linkage plate 20 pushes the locking ring 19 to extend the treatment head 8 to the preset end point of the stroke, the ends of multiple first linkages 12 simultaneously abut against the inner wall of the treatment head 8, mechanically stopping the locking ring 19. At this time, the remaining impact kinetic energy is distributed to multiple sets of linkages and the stopping mechanism. The treatment head 8 obtains a wide pulse output with a gentle rise and a peak pressure reduction of more than 50%, which acts on the user's uncomfortable area to achieve "soft impact" low-pain treatment. S4: As the linkage plate 20 moves downward, multiple pressure blocks 17 fixed on the linkage plate 20 simultaneously press the corresponding top rod 13. The top rod 13 moves downward, driving the contact plate 23 to compress the return spring 24 in the sleeve 18. At the same time, the top pressure plate 22 fixed at the lower end of the top rod 13 slides downward in the liquid storage cavity 11, gradually squeezing out the pre-filled medical coupling agent in the cavity through the micropores of the release mesh gasket 7. The squeezed-out coupling agent evenly penetrates along the outer surface of the treatment head 8 to the end face in contact with the skin, automatically replenishing the coupling layer lost due to impact vibration or evaporation, ensuring stable acoustic impedance matching, and avoiding energy attenuation. S5: After one impact, the return spring 24 releases its elastic potential energy, pushing the contact plate 23 and the push rod 13 upward to reset. The push rod 13 pushes the linkage plate 20 upward through the pressure block 17, causing the second link 21 to unfold and the first link 12 to open and release the locking ring 19. At the same time, the pressure plate 22 moves upward with the push rod 13, causing the treatment head 8 to retract to the initial position. During the upward movement of the linkage plate 20, the impact pin 26 is also pushed backward to reset. Thus, a complete impact-release-reset cycle ends. The device automatically repeats steps S2 to S5 at a preset frequency to achieve continuous low-pain impact treatment. Each impact releases a small amount of coupling agent simultaneously, and no manual interruption or reapplication is required throughout the process.

10. A control method for a shockwave therapy device according to any one of claims 1-9, characterized in that, The method specifically includes the following steps: S1: The operator first reliably connects the ballistic guide tube (2) to the air inlet head (6), confirms that the air source pipeline is unobstructed, and sets the impact parameters through the control panel (4), including the impact frequency adjustable from 1 to 20 Hz, the output energy level, and the corresponding driving air pressure of 0.2 to 0.6 MPa. Depending on the user's discomfort location and pain sensitivity, the operator selects whether to enable the "soft impact mode". After confirming that a small amount of coupling agent has been initially applied between the treatment head (8) and the skin, the operator starts the device. S2: Then the compressed gas enters the ballistic guide tube (2) through the gas inlet (6), pushing the impact pin (26) forward at high speed. The impact pin (26) first hits the buffer piston (25) in the first-stage buffer assembly (554). The buffer piston (25) compresses the inert gas in the buffer cylinder (10). This process absorbs about 30%-50% of the initial kinetic energy at the moment of impact, extending the rise time of the originally steep pressure pulse to 12-15 microseconds, achieving the first "peak reduction" buffer, effectively reducing the impact vibration transmitted to the handle and the user's initial stinging sensation. S3: After the impact pin (26) passes through the guide seat (16), it abuts against the bottom of the linkage plate (20), pushing the linkage plate (20) to move downward. The linkage plate (20) pulls the first linkage (12) through multiple second linkages (21) to rotate synchronously around the pin on the guide seat (16). When the linkage plate (20) pushes the locking ring (19) to drive the treatment head (8) to extend to the preset end point of the stroke, the ends of multiple first linkages (12) simultaneously abut against the inner wall of the treatment head (8), mechanically stopping the locking ring (19). At this time, the remaining impact kinetic energy is dispersed to multiple sets of linkages and the stopping mechanism. The treatment head (8) obtains a wide pulse output with a gentle rise and a peak pressure reduction of more than 50%, which acts on the user's uncomfortable parts to achieve "soft impact" low pain treatment. S4: While the linkage plate (20) moves downward, multiple pressure blocks (17) fixed on the linkage plate (20) press the corresponding top rod (13) simultaneously. The top rod (13) moves downward, driving the contact plate (23) to compress the return spring (24) in the sleeve (18). At the same time, the top pressure plate (22) fixed at the lower end of the top rod (13) slides downward in the liquid storage cavity (11), gradually squeezing out the pre-filled medical coupling agent in the cavity through the micropores of the release mesh gasket (7). The squeezed coupling agent evenly penetrates along the outer surface of the treatment head (8) to the end face in contact with the skin, automatically replenishing the coupling layer lost due to impact vibration or evaporation, ensuring stable acoustic impedance matching, and avoiding energy attenuation. S5: After one impact is completed, the reset spring (24) releases its elastic potential energy, pushing the contact plate (23) and the top rod (13) to reset upwards. The top rod (13) pushes the linkage plate (20) to rise through the pressure block (17), causing the second link (21) to unfold and the first link (12) to open and release the locking ring (19). At the same time, the top pressure plate (22) moves upwards with the top rod (13), causing the treatment head (8) to retract to the initial position. During the upward movement of the linkage plate (20), the impact pin (26) is also pushed to reset backwards. Thus, a complete impact-release-reset cycle ends, and the equipment automatically repeats steps S2 to S5 at the preset frequency.
