Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a pneumatic shock wave treatment device. Background Art

[0002] Extracorporeal pneumatic shock wave therapy equipment generally consists of a shock wave probe and a gas source. The gas source provides pulse gas to the shock wave probe, thereby causing the shock wave probe to generate shock waves.

[0003] Most existing pneumatic shock wave therapy devices rely on high-pressure gas cylinders to supply gas to the shock wave probe. Before use, the high-pressure gas cylinder needs to be inflated by a compressor in advance. When assembling the pneumatic shock wave therapy device, a reversing stop valve needs to be set between the gas cylinder and the probe to achieve control of the shock wave frequency.

[0004] During the treatment of bacterial vaginosis, bacteria will form biofilms on the vaginal wall, affecting drug absorption. If shock waves can be used to destroy the biofilm during treatment, the therapeutic effect of the drug will be significantly improved. For shock wave treatment of vaginal disease, for different parts of the vagina or for different strains, sometimes too large shock waves can easily cause secondary damage to the inner wall of the vagina, and too small shock waves can cause unsatisfactory treatment effects. In addition, since the skin on the inner wall of the vagina is more fragile than the skin outside the body, it is sometimes necessary to frequently try shock waves of different intensities during treatment to find the best treatment effect. In existing pneumatic shock wave treatment equipment, the probe can only generate shock waves in the axial direction, which makes it difficult for such equipment to be used in the treatment of vaginal diseases. In addition, existing equipment uses gas cylinders for gas supply. During the treatment process, if medical staff find that the current intensity of shock wave treatment is not ideal and need to increase or decrease the intensity of the shock wave, they can only replace gas cylinders with other pressures, or use a compressor to increase the pressure in the gas cylinder, or manually release some of the pressure in the gas cylinder. Not only is the operation cumbersome, but this adjustment method is one-way, and the use scenario is very limited. Summary of the invention

[0010] In an embodiment of the present invention, there are multiple shock wave generating channels and multiple shock wave generators, and the multiple shock wave generators are respectively arranged in a one-to-one correspondence with the multiple shock wave generating channels. The air guide tube core includes multiple air guide tube segments connected in sequence from the proximal end to the distal end, and at least one connecting branch is provided on the peripheral wall of each air guide tube segment, and the connecting branch is used to be connected to the shock wave generator in a one-to-one correspondence; wherein, between any adjacent air guide tube segments, the tube cavity cross-sectional area of ​​the proximal air guide tube segment is larger than the tube cavity cross-sectional area of ​​the distal air guide tube segment.

[0011] In an embodiment of the present invention, the compression cylinder is a double-headed cylinder and is provided with a first extending rod end and a second extending rod end, the compression chamber is arranged corresponding to the first extending rod end, the pushing assembly includes a first cam and a second cam respectively arranged corresponding to the first extending rod end and the second extending rod end, the first cam and the second cam are used to alternately apply axial thrust to the first extending rod end and the second extending rod end; the air source generating assembly also includes a driving assembly for driving the first cam and the second cam to rotate synchronously.

[0012] In an embodiment of the present invention, a compression cylinder comprises a cylinder body and a piston rod, the piston rod is inserted into the cylinder body and two ends of the piston rod are respectively a first extending rod end and a second extending rod end, the first extending rod end and the second extending rod end extend from two ends of the cylinder body respectively, the second plug body portion of the piston rod divides the inner cavity of the cylinder body into an air intake chamber and a compression chamber, an air intake port and an air exhaust port connecting the air intake chamber and the compression chamber are respectively provided on the cylinder wall of the cylinder body, and a one-way channel connecting the air intake chamber to the compression chamber is also provided on the piston rod; wherein the one-way air intake channel comprises an air intake port, an air intake chamber and a one-way channel, and the air outlet channel comprises an exhaust port, and the exhaust port is connected to the air guide core through a pipeline.

[0013] In an embodiment of the present invention, the one-way channel is a conical channel arranged on the second plug body portion, and the port cross-sectional area of ​​the conical channel at one end close to the air inlet chamber is smaller than the port cross-sectional area of ​​the conical channel at one end close to the compression chamber. A ball and a spring are arranged in the conical channel, and the piston rod also includes a first clamping plate and a second clamping plate installed on both sides of the second plug body portion, and the first clamping plate and the second clamping plate are used to keep the ball in the conical channel, and the spring is arranged on the side of the ball facing the large mouth of the conical channel.

[0014] In an embodiment of the present invention, the driving assembly includes a motor, a first driving wheel, a second driving wheel and a synchronous transmission belt.

[0016] Through the above technical solution, the pneumatic shock wave therapy device provided by the embodiment of the present invention has the following beneficial effects:

[0017] When the push assembly drives the piston rod to move toward the compression chamber, the second plug body of the piston rod will compress the gas in the compression chamber. When the piston rod moves to a certain position, the pressure of the gas in the compression chamber will be greater than the opening pressure of the pressure relief valve, and the pressure relief valve will open. At this time, the high-pressure gas in the compression chamber will provide high-pressure gas to the air guide core through the outlet channel. Since the air guide core is connected to the shock wave generator pipeline, the high-pressure gas in the air guide core will act on the shock wave generator through the pipeline. The shock wave generator will generate radial shock waves under the drive of high-pressure gas. After the shock wave acts on the isolation membrane, it will act on the inner wall of the vagina through the transmission of the isolation membrane, thereby destroying the bacterial biofilm on the inner wall of the vagina. When the compression cylinder completes the compression-exhaust process, the push assembly will push the piston rod to move in the opposite direction and reset. At this time, the compression chamber is supplemented with gas through the one-way air inlet channel, and the pressure relief valve is closed. Through the action of the push assembly, the compression cylinder can stably and continuously generate pulse gas. Due to the existence of the pressure relief valve, the pressure relief valve will only open when the gas pressure in the compression chamber reaches the set value, thereby ensuring that the pulse gas output by the compression cylinder acts on the shock wave generator with the same pressure each time; furthermore, when using it, medical staff only need to adjust the pressure relief preload of the preload spring in the pressure relief valve to adjust the pulse gas pressure, and it is very convenient to adjust whether the pressure is increased or decreased. In summary, this device can not only generate ultrasonic waves in the radial direction, but also accurately control the intensity of ultrasonic waves, making it more suitable for the treatment of vaginal diseases.

DETAILED DESCRIPTION

[0036] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0037] The pneumatic shock wave therapy device of the present invention will be described below with reference to the accompanying drawings.

[0038] The present invention provides a pneumatic shock wave therapy device for shock wave therapy, such as Figure 1 As shown, the pneumatic shock wave therapy device includes a probe assembly X and an air source generating assembly Z.

[0039] Specifically, if Figure 2 As shown, the probe assembly X includes a tube body 1, an air guide core 3 and a shock wave generator 2. The distal end of the tube body 1 is closed and the proximal end is open. A shock wave generating channel 11 closed by an isolation membrane 12 is inlaid on the peripheral wall of the tube body 1. The shock wave generator 2 is arranged in the shock wave generating channel 11 and is located radially inside the isolation membrane 12. The shock wave generating end of the shock wave generator 2 is radially arranged toward the isolation membrane 12. The air guide core 3 is arranged in the tube body 1 and is connected to the shock wave generator 2 pipeline.

[0040] like Figure 7 and Figure 8As shown, the gas source generating assembly Z includes a compression cylinder 5 and a push assembly 7. One of the chambers of the compression cylinder 5 is a compression chamber 5c. The cylinder wall of the compression cylinder 5 is also provided with a one-way air inlet channel 5f and an air outlet channel 5d connected to the compression chamber 5c. The air outlet channel 5d is connected to the air guide core 3 pipeline and a pressure-adjustable pressure relief valve 61 is provided in the air outlet channel 5d. The push assembly 7 is used to drive the piston rod 52 of the compression cylinder 5 to reciprocate.

[0041] When the push assembly 7 drives the piston rod 52 to move toward the compression chamber 5c, the second plug body 521 of the piston rod 52 will compress the gas in the compression chamber 5c. When the piston rod 52 moves to a certain position, the pressure of the gas in the compression chamber 5c will be greater than the opening pressure of the pressure relief valve 61, and the pressure relief valve 61 will open. At this time, the high-pressure gas in the compression chamber 5c will provide high-pressure gas to the air guide core 3 through the air outlet channel 5d. Since the air guide core 3 is connected to the shock wave generator 2 pipeline, the high-pressure gas in the air guide core 3 will act on the shock wave generator 2 through the pipeline. The shock wave generator 2 will generate a radial shock wave driven by the high-pressure gas. After the shock wave acts on the isolation membrane 12, it will act on the inner wall of the vagina through the transmission of the isolation membrane 12, thereby destroying the bacterial biofilm on the inner wall of the vagina. When the compression cylinder 5 completes the compression-exhaust process, the push assembly 7 will push the piston rod 52 to move in the opposite direction and reset. At this time, the compression chamber 5c is replenished with air through the one-way air inlet channel 5f, and the pressure relief valve 61 is closed; through the action of the push assembly 7, the compression cylinder 5 can stably and continuously generate pulse gas. Due to the existence of the pressure relief valve 61, the pressure relief valve 61 will only open when the gas pressure in the compression chamber 5c reaches the set value, thereby ensuring that the pressure of the pulse gas output by the compression cylinder 5 on the shock wave generator 2 is the same each time; furthermore, when using it, medical staff only need to adjust the pressure relief preload of the preload spring in the pressure relief valve 61 to adjust the pulse gas pressure, and it is very convenient to adjust whether the pressure is increased or decreased. In summary, this device can not only generate ultrasonic waves in the radial direction, but also accurately control the intensity of ultrasonic waves, so it is more suitable for the treatment of vaginal diseases.

[0042] like Figure 2 , Figure 3 and Figure 5As shown, in the embodiment of the present invention, the shock wave generator 2 includes an air guide cover 21, an impact member 22 and a reset member 23, the air guide cover 21 is limitedly installed in the shock wave generating channel 11 and a shock wave generating cavity 211 is formed inside the air guide cover 21, the impact member 22 is arranged in the shock wave generating cavity 211, the shock wave generating cavity 211 is provided with an outer end opening 211a radially outward and an inner end opening 211b radially inward, and a pressure relief channel 214 communicating with the inner cavity of the tube body 1 is further provided on the peripheral wall of the air guide cover 21, and the pressure relief channel 214 is located at It is located between the outer end opening 211a and the inner end opening 211b and is used to connect the inner end opening 211b and the inner cavity of the tube body 1 when the impact member 22 moves a preset distance toward the outer end opening 211a; the probe assembly X also includes an air guide core 3 arranged in the tube body 1, and the air guide core 3 is used to sequentially provide high-pressure gas to the inner end opening 211b. The reset member 23 is used to drive the impact member 22 to move toward the inner end opening 211b when the air pressure in the air guide core 3 is lower than a preset value, so that the channel between the pressure relief channel 214 and the inner end opening 211b is cut off.

[0043] When the gas in the air guide core 3 is at high pressure, the gas pressure needs to be much greater than the driving force of the reset member 23, so that the impact member 22 can be accelerated instantly and quickly impact the isolation membrane 12 to ensure the energy intensity of the shock wave. The pressure relief channel 214 can release the excess gas in the air guide core 3 through the pressure relief channel 214 when the impact member 22 moves a preset distance toward the outer end opening 211a, thereby reducing the gas pressure of the air guide core 3 and ensuring the subsequent reset member 23 to quickly reset the impact member 22. When the gas in the air guide core 3 is at low pressure, the reset member 23 will drive the impact member 22 to reset to the position of blocking the inner end opening 211b, so that when the air guide core 3 provides high-pressure gas in the next beat, the energy of the high-pressure gas can act more on the reset member 23 to ensure the effective transfer of energy.

[0044] like Figure 5 As shown, in an embodiment of the present invention, the air guide hood 21 includes a cone portion 215 and a duct portion 216, the duct portion 216 is connected to the small opening of the cone portion 215, the large opening of the cone portion 215 is the outer end opening 211a of the shock wave generating cavity 211, and the opening of the duct portion 216 at one end away from the cone portion 215 is the inner end opening 211b; one end of the impact member 22 is located in the lumen of the duct portion 216, and the other end is used to extend into the inner cavity of the cone portion 215 when the impact member 22 moves a preset stroke toward the cone portion 215, and the duct portion 216 is used to guide the impact member 22 to move radially toward the cone portion 215.

[0045] Among them, Figure 5As shown, a limit step 212 is further provided between the cone portion 215 and the conduit portion 216, and the impact member 22 includes a first plug body portion 221 and a rod body portion 222. The first plug body portion 221 is located in the tubular cavity of the conduit portion 216, one end of the rod body portion 222 is connected to the first plug body portion 221, and the other end is used to pass through the limit step 212 and impact the isolation membrane 12 located at the outer end opening 211a when the impact member 22 moves a preset stroke toward the cone portion 215. By setting the conduit portion 216, the radial movement path of the impact member 22 can be guaranteed, thereby ensuring that the impact member 22 can accurately impact the designated area of ​​the isolation membrane 12 in a vertical posture each time.

[0046] like Figure 3 and Figure 5 As shown, in an embodiment of the present invention, a through hole may be provided on the first plug body 221, and the through hole can ensure that the first plug body 221 is reset to the area between the pressure relief channel 214 and the inner end opening 211b under the action of the elastic member. The aperture of the through hole needs to be set to a small hole to ensure that the gas energy acts more on the first plug body 221.

[0047] like Figure 5 As shown, in the embodiment of the present invention, the reset member 23 is an elastic member and is arranged between the limit step 212 and the first plug body 221. The reset member 23 can be an elastic member or a magnetic member. By arranging the elastic member between the limit step 212 and the first plug body 221, the impact member 22 can be quickly reset.

[0048] like Figure 3 and Figure 5 As shown, in the embodiment of the present invention, the shock wave generator 2 further includes a vibration-uniform metal sheet 242, which is attached to the radial inner side of the isolation membrane 12 and closes the outer end opening 211a, and the rod body 222 radiates the impact force uniformly to the isolation membrane 12 through the vibration-uniform metal sheet 242. By providing the vibration-uniform metal sheet 242, the vibration generated by the impact of the rod body 222 can be radiated more uniformly on the surface of the isolation membrane 12, thereby ensuring the uniformity of the shock wave energy.

[0049] like Figure 3 and Figure 5 As shown, in the embodiment of the present invention, a gas pressure balance channel 213 is provided on the cone side wall of the cone portion 215, and the gas pressure balance channel 213 is connected to the inner cavity of the tube body 1 and the inner cavity of the cone portion 215. By providing the gas pressure balance channel 213, it can be ensured that the high-pressure gas can drive the impact member 22 to work normally, and the kinetic energy loss of the impact member 22 due to excessive pressure in the inner cavity of the cone portion 215 can be avoided.

[0050] In an embodiment of the present invention, the isolation membrane 12 may be a capsule filled with a liquid medium. By filling the capsule with different media, the amplitude and energy field of the shock wave can be changed, so that the medium of the capsule can match the current frequency and energy density of the shock wave, thereby better breaking the bacterial biofilm. The capsule can be sealed and embedded in the shock wave generating channel 11 by glue bonding. When the glue is bonded, the sealing between the capsule and the peripheral wall of the tube body 1 needs to be ensured.

[0051] like Figure 2 and Figure 4 As shown, in an embodiment of the present invention, the number of shock wave generating channels 11 and the number of shock wave generators 2 are respectively multiple, and the multiple shock wave generators 2 are respectively arranged in a one-to-one correspondence with the multiple shock wave generating channels 11, and the air guide tube core 3 includes a plurality of air guide tube segments connected in sequence from the proximal end to the distal end, and at least one connecting branch 31 is provided on the peripheral wall of each air guide tube segment, and the connecting branch 31 is used to be connected to the shock wave generator 2 in a one-to-one correspondence; wherein, between any adjacent air guide tube segments, the tube cavity cross-sectional area of ​​the proximal air guide tube segment is larger than the tube cavity cross-sectional area of ​​the distal air guide tube segment.

[0052] The device can generate radial shock waves at multiple positions of the tube body 1, thereby increasing the range of shock waves. For patients with a large area of ​​vaginal inflammation, medical staff only need to slightly rotate the tube body 1 or slightly adjust the insertion depth of the tube body 1 when using it to ensure that the inflamed area of ​​the vaginal inner wall can be irradiated by the shock wave. In the process of high-pressure gas flowing from the proximal end of the airway core 3 to the distal end of the airway core 3, the connecting branch 31 shunts the gas of the airway core 3, and the gas pressure in the airway core 3 will be reduced by a part; in order to ensure that the gas pressure in the airway core 3 is the same when it is shunted to each connecting branch 31 (that is, to ensure that each shock wave generator 2 can generate shock waves of the same size), in an embodiment of the present invention, the cross-sectional area of ​​the tube cavity of the airway core 3 can be set to be gradually smaller from the proximal end to the distal end, that is, the airway core 3 is thick at the proximal end and thin at the distal end.

[0053] Furthermore, if Figure 4 As shown, in the embodiment of the present invention, between any adjacent airway segments, the ratio of the cross-section Si:Si+1 of the proximal airway segment to the distal airway segment approximately satisfies Si:Si+1=ΣAi:ΣAi+1, and a certain range of error is allowed; wherein, i represents the i-th airway segment counted from the proximal end of the airway core 3, i+1 represents the airway segment adjacent to the i-th airway segment and closer to the distal end, Si represents the cross-sectional area of ​​the i-th airway segment, Si+1 represents the cross-sectional area of ​​the i+1-th airway segment, ΣAi represents the total number of connecting branches 31 from the i-th airway segment to the most distal airway segment, and ΣAi+1 represents the total number of connecting branches 31 from the i+1-th airway segment to the most distal airway segment.

[0054] Taking the example that the air guide tube core 3 is composed of three air guide tube segments, assuming that three connecting branches 31 are connected to the peripheral wall of each air guide tube segment, at this time, the air guide tube segment closest to the proximal end is taken as the first tube segment, and the ratio of the cross-sectional area of ​​the first tube segment to the adjacent second tube segment satisfies S1:S2=(3*3):(2*3)=3:2.

[0055] like Figure 3 As shown, in the embodiment of the present invention, a transition connection part 32 with an arc-shaped transition is formed between any adjacent air guide pipe sections, one end of the connecting branch pipe 31 is the branch pipe air inlet end, and the other end is the branch pipe air outlet end, the branch pipe air inlet end is axially (i.e., the far and near direction of the air guide pipe core 3) extendedly connected to the transition connection part 32, and the branch pipe air outlet end radially extends toward the corresponding shock wave generating channel 11, from the branch pipe air inlet end to the branch pipe air outlet end, the connecting branch pipe 31 is arc-shaped transition. The transition connection part 32 and the arc transition can guide the flow of gas to avoid a large loss of gas pressure due to gas diversion or gas flow turning.

[0056] like Figure 2 and Figure 4 As shown, in an embodiment of the present invention, the connecting branch pipe 31 corresponds to the shock wave generating channel 11 in number and is radially aligned in position, and the connecting branch pipe 31 is used to radially dock with the shock wave generator 2 in the aligned shock wave generating channel 11. That is, when the shock wave generator 2 is installed, after the air guide pipe core 3 is inserted into the tube body 1, the air guide pipe core 3 is first rotated to align the connecting branch pipe 31 with the shock wave generating channel 11, and then the shock wave generator 2 is inserted from the outside of the shock wave generating channel 11, so that the conduit portion 216 of the shock wave generator 2 is engaged or threaded with the connecting branch pipe 31, and the connecting branch pipe 31 is limited by the conduit portion 216, and the air guide cover 21 is limited by the inner wall of the shock wave generating channel 11, so as to complete the rapid installation of the shock wave generator 2. Through the above arrangement, the rapid assembly and disassembly function of the air guide pipe core 3 and the shock wave generator 2 can be realized, which is convenient for the subsequent replacement of vulnerable parts.

[0057] like Figure 4 As shown, in an embodiment of the present invention, the connecting branch pipe 31 is provided with an arc-shaped transition so that the direction in which the gas finally flows into the shock wave generator 2 is the same as the direction in which the shock wave is generated. By guiding the gas, the shock wave generator 2 can generate a radial shock wave with greater energy and reduce the pressure loss of the gas.

[0058] like Figure 7 and Figure 8As shown, in the embodiment of the present invention, the compression cylinder 5 can be a double-headed cylinder and is provided with a first extension rod end 5a and a second extension rod end 5b, the compression chamber 5c is arranged corresponding to the first extension rod end 5a, and the push assembly 7 includes a first cam 71 and a second cam 72 respectively arranged corresponding to the first extension rod end 5a and the second extension rod end 5b, and the first cam 71 and the second cam 72 are used to alternately apply axial thrust to the first extension rod end 5a and the second extension rod end 5b; the gas source generating assembly Z also includes a driving assembly for driving the first cam 71 and the second cam 72 to rotate synchronously. Of course, the compression cylinder 5 can also be a single-headed cylinder.

[0059] Continuing with the example of the double-headed cylinder, the drive assembly drives the second cam 72 to rotate, and the second cam 72 will apply a thrust to the second extension rod end 5b of the piston rod 52, so that the piston rod 52 moves in the extension direction of the first extension rod end 5a, and the movement of the piston rod 52 will compress the gas in the compression chamber 5c. When the piston rod 52 moves to a certain position, the pressure of the gas in the compression chamber 5c will be greater than the opening pressure of the pressure relief valve 61, and the pressure relief valve 61 will open. At this time, the high-pressure gas in the compression chamber 5c will provide high-pressure gas to the outside through the gas outlet channel 5d. After the second cam 72 pushes, the first cam 71 will apply a thrust to the first extension rod end 5a of the piston rod 52, so that the piston rod 52 moves in the extension direction of the second extension rod end 5b and resets. At this time, the compression chamber 5c is replenished with gas; through the alternating cooperation of the first cam 71 and the second cam 72, it can be ensured that the compression cylinder 5 can stably and continuously generate pulse gas. Due to the existence of the pressure relief valve 61, the pressure of the pulse gas output by the compression cylinder 5 can be guaranteed to be the same each time, thereby ensuring that the energy intensity of the shock wave generated each time is the same. Furthermore, when using it, medical staff only need to adjust the pressure relief preload force of the preload spring in the pressure relief valve 61 to achieve the regulation of the pulse gas pressure, which is very convenient to adjust.

[0060] Furthermore, if Figure 7 and Figure 8As shown, in the embodiment of the present invention, the double-headed cylinder may include a cylinder body 51 and a piston rod 52, the piston rod 52 is inserted into the cylinder body 51 and the two ends of the piston rod 52 are respectively a first extending rod end 5a and a second extending rod end 5b, the first extending rod end 5a and the second extending rod end 5b extend from the two ends of the cylinder body 51 respectively, the second plug body portion 521 of the piston rod 52 divides the inner cavity of the cylinder body 51 into an air intake chamber 5f2 and a compression chamber 5c, and the cylinder wall of the cylinder body 51 is respectively provided with There is an air inlet 5f1 and an air exhaust port 5d1 connecting the air inlet chamber 5f2 and the compression chamber 5c. The piston rod 52 is also provided with a one-way channel 5f3 which is one-way connected from the air inlet chamber 5f2 to the compression chamber 5c. The one-way channel 5f3 is configured to be conductive when the gas flows from the air inlet chamber 5f2 to the compression chamber 5c and to be blocked in the reverse direction; wherein the one-way air inlet channel 5f is at least composed of the air inlet port 5f1, the air inlet chamber 5f2 and the one-way channel 5f3, and the air outlet channel 5d includes the air exhaust port 5d1.

[0061] When the piston rod 52 moves toward the extension direction of the first extension rod end 5a, the piston rod 52 compresses the gas in the compression chamber 5c, and the air intake chamber 5f2 takes in air through the air intake port 5f1. When the piston rod 52 moves to a certain position in the extension direction of the second extension rod end 5b, the pressure in the compression chamber 5c is lower than the pressure in the air intake chamber 5f2. At this time, the gas in the air intake chamber 5f2 can enter the compression chamber 5c through the air intake port 5f1, the air intake chamber 5f2 and the one-way channel 5f3, thereby achieving air replenishment in the compression chamber 5c.

[0062] like Figure 8 and Fig. 9 As shown, in the embodiment of the present invention, the one-way channel 5f3 can be a tapered channel provided on the second plug body 521, and the tapered channel is close to one end of the air inlet cavity 5f2 ( Figure 2 The left end in the figure) is a small opening with a small cross-sectional area, and the conical passage is close to one end of the compression chamber 5c ( Figure 2 The right end of the second plug body 521 is a large opening with a large cross-sectional area. A ball and a spring can be installed in the tapered channel. The first clamp 522 and the second clamp 523 can be installed on both sides of the second plug body 521. The first clamp 522 is located on the side of the second plug body 521 close to the compression chamber 5c. The first clamp 522 and the second clamp 523 are used to keep the ball in the tapered channel. The spring is arranged between the ball and the first clamp 522 and is used to prevent the ball from being completely attached to the first clamp 522, causing the air holes on the first clamp 522 to be blocked. When the pressure in the compression chamber 5c is greater than the pressure in the air inlet chamber 5f2, the ball will move toward the small end of the tapered channel to cut off the tapered channel. When the pressure in the compression chamber 5c is less than the pressure in the air inlet chamber 5f2, the ball will move toward the large opening of the tapered channel, and the tapered channel is conductive at this time.

[0063] like Figure 7 and Figure 8As shown, in the embodiment of the present invention, the compression cylinder 5 may include a first end cover 53 and a second end cover 54 in addition to the cylinder body 51. The first end cover 53 and the second end cover 54 are respectively used to block the two ends of the cylinder body 51, and the first extension rod end 5a and the second extension rod end 5b are respectively correspondingly passed through the first end cover 53 and the second end cover 54. The first end cover 53 and the second end cover 54 facilitate not only the sealing of the ports at the two ends of the cylinder body 51, but also the installation of the piston rod 52.

[0064] like Figure 7 and Figure 8 As shown, in the embodiment of the present invention, the first end cover 53 and the second end cover 54 are preferably detachably mounted on both ends of the cylinder body 51, the air inlet 5f1 can be arranged on the second end cover 54, and the air outlet 5d1 and the air outlet passage can be arranged on the first end cover 53. By detachably arranging the first end cover 53 and the second end cover 54, the processing of the air inlet 5f1 and the air outlet 5d1 and the assembly of the compression cylinder 5 are facilitated.

[0065] In order to alternately apply axial thrust to the first and second extended rod ends 5a and 5b, as shown in FIG. Figure 2 As shown, in the embodiment of the present invention, the phase angles of the first cam 71 and the second cam 72 may differ by 90°. Of course, in some cases, two cams with other angle differences may also be able to achieve the above-mentioned alternating function.

[0066] like Figure 7 As shown, in an embodiment of the present invention, the driving assembly includes a motor 81, a first driving wheel 82, a second driving wheel 83 and a synchronous transmission belt 84. The connecting shaft of the first cam 71 is transmission-connected to the first driving wheel 82, the connecting shaft of the second cam 72 is transmission-connected to the second driving wheel 83, and the synchronous transmission belt 84 is sleeved on the first driving wheel 82 and the second driving wheel 83. The motor 81 is used to drive one of the first driving wheel 82, the second driving wheel 83 and the synchronous transmission belt 84 to move. The transmission form of the synchronous transmission belt 84 is preferably a meshing transmission. Through the synchronous transmission belt 84, the synchronous rotation of the first cam 71 and the second cam 72 can be achieved.

[0067] In the embodiment of the present invention, the first driving wheel 82 and the second driving wheel 83 may also be driven by two motors 81 respectively. In order to ensure the synchronization between the first cam 71 and the second cam 72, higher requirements are required for the control of the motor 81.

[0068] like Figure 7 As shown, in the embodiment of the present invention, the number of the compression cylinder 5, the first cam 71 and the second cam 72 are multiple, and the compression cylinder 5, the first cam 71 and the second cam 72 are respectively arranged one by one. The multiple compression cylinders 5 can be connected in parallel or in series. Fig.12 and Fig.13 As shown, taking three compression cylinders 5 as an example, the three compression cylinders 5 can be defined as the first cylinder, the second cylinder and the third cylinder respectively. When connected in parallel, the exhaust ports 5d1 of the first cylinder, the second cylinder and the third cylinder are combined into one pipeline through a pipeline to achieve a large flow output of compressed gas of the shock wave gas source generating device. When connected in series, the exhaust port 5d1 of the first cylinder and the exhaust port 5d1 of the second cylinder can be connected to the air inlet 5f1 of the third cylinder to achieve the output of higher pressure compressed gas of the shock wave gas source generating device. Among them, when connected in series, the air inlet 5f1 of the third cylinder needs to be installed with a check valve, or the pressure relief valve 61 is set as a one-way pressure relief valve 61.

[0069] like Fig.10 As shown, in the embodiment of the present invention, in order to facilitate the installation of the pressure relief valve 61, an installation channel connected to the air outlet channel 5d can be set on the cylinder wall of the cylinder body 51, and the pressure relief valve 61 is installed in the installation channel and the head end of the pressure relief valve 61 extends into and blocks the air outlet channel 5d, and the head end of the pressure relief valve 61 is set in a conical shape. A preload spring for providing preload force to the head end of the pressure relief valve 61 is also provided inside the pressure relief valve 61, and the first adjusting member 62 is a telescopic push member, which can be an electric cylinder, a pneumatic cylinder, a motor 81 screw, etc. The telescopic rod end of the first adjusting member 62 acts on the preload spring; wherein, the action direction of the preload spring is opposite to the air outlet direction of the air outlet channel 5d at the installation channel. When the pressure of the gas in the compression chamber 5c is greater than the preload force of the preload spring, the gas will overcome the preload force of the preload spring and push open the head end of the pressure relief valve 61, and the air outlet channel 5d will discharge the gas outward; when the pressure of the gas in the compression chamber 5c is less than the preload force of the preload spring, the preload spring will keep the head end of the pressure relief valve 61 in a state of blocking the air outlet channel 5d, and the air outlet channel 5d is in a cut-off state.

[0070] like Figure 7 As shown, in an embodiment of the present invention, the shock wave gas source generating device further comprises a box body 9, on which an air inlet and outlet fence and an air outlet interface are provided, and a compression cylinder 5, a push assembly 7 and a driving assembly are arranged in the box body 9.

[0071] like Figure 7 As shown, in order to facilitate the movement of the cylinder body 51, in an embodiment of the present invention, the compression cylinder 5 may further include a sliding guide rod 63, which is arranged along the extension direction of the piston rod 52. The cylinder body 51, and / or the first end cover 53, and / or the second end cover 54 of the compression cylinder 5 can be slidably matched with the sliding guide rod 63. By setting the sliding guide rod 63, the directional movement of the cylinder body 51 is facilitated.

[0072] For the gas source generating assembly Z of the present device, the intensity of the shock wave generated by the shock wave generator 2 is not only related to the pressure of the gas output by the compression cylinder 5, but also to the output duration of the gas. For example, when 0.01s of high-pressure gas and 0.05s of high-pressure gas act on the shock wave probe respectively, the intensities of the shock waves generated by the probe must be different.

[0073] Therefore, in order to further achieve precise control of the intensity of the shock wave, in an embodiment of the present invention, the gas source generating assembly Z may also include an adjusting component and a controller, the adjusting component including a first adjusting member 62 for adjusting the pressure relief opening pressure of the pressure relief valve 61 and a second adjusting member (not shown in the figure) for driving the cylinder body 51 to move relative to the piston rod 52; the controller is used to adjust the position of the cylinder body 51 relative to the piston rod 52 according to the preset mapping relationship between the pressure relief opening pressure and the position of the cylinder body 51 after the pressure relief opening pressure of the pressure relief valve 61 is adjusted, so as to adjust the compression ratio of the compression cylinder 5, thereby adjusting the output duration of the compression cylinder 5 each time the high-pressure gas is output.

[0074] Let’s take a specific case as an example. Fig.11 As shown, in this case, the cylinder cavity length of the compression cylinder 5 is 20 cm. Assuming that each 1 cm length of the cylinder cavity represents a unit of volume, the movement stroke of the piston rod 52 is 12 cm under the action of the push assembly 7. By adjusting the position of the cylinder body 51 relative to the piston rod 52, the second plug body 521 can move between 1-13 cm, 2-14 cm, 3-15 cm, 4-16 cm, 5-17 cm, 6-18 cm, and 7-19 cm in the cylinder cavity. The compression ratio of the compression cylinder 5 will be different depending on the initial and final moving positions of the second plug body 521. Based on this, a comparison relationship table between the compression ratio of the compression cylinder 5 and the initial and final positions of the second plug body 521 can be generated as shown in the following table:

[0075]

[0076] According to the input treatment parameters, assuming that the opening pressure of the pressure relief valve 61 is adjusted to 5 bar, before the position of the cylinder 51 relative to the piston rod 52 is adjusted, the second plug body 521 moves between 5.5-17.5 cm in the cylinder cavity, the second plug body 521 is at 5.5 cm, and the pressure of the compression chamber 5c is atmospheric pressure (1 bar). If the device is operated according to this parameter, the piston rod 52 moves to 17.1 cm (1 bar*(20-5.5) / (20-17.1)=5 bar), and the pressure The pressure in the contraction chamber 5c will theoretically reach 5 bar. When the piston rod 52 moves between 17.1-17.5 cm, the pressure relief valve 61 will be in an open state and continue to output high-pressure gas. At this time, the time for the compression cylinder 5 to output high-pressure gas is only the time it takes the piston rod 52 to move 0.4 cm. If treatment is performed at a shock wave frequency of 10 Hz, the time for the pressure relief valve 61 to output high-pressure gas is only 0.0016 s. The high-pressure gas output during this time may very likely result in insufficient flow of the output high-pressure gas.

[0077] In the preset mapping relationship, if the opening pressure of 5 bar corresponds to the second plug body 521 moving between 6-18 cm in the cylinder cavity, then after adjusting the position of the cylinder body 51 relative to the piston rod 52 according to the preset mapping relationship, when the plug rod moves to 17.2, the pressure of the compression chamber 5c will reach 5 bar, and when the piston rod 52 moves between 17.2-18 cm, the pressure relief valve 61 continues to open and output high-pressure gas, and the exhaust time of the compression cylinder 5 is doubled. Obviously, by adopting the control strategy in this controller, when adjusting the opening pressure of the pressure relief valve 61, the controller can adaptively adjust the opening time of the pressure relief valve 61, thereby realizing accurate control of the shock wave intensity.

[0078] It is understandable that, when setting the actual parameters, the preset mapping relationship can be specifically modulated according to the changes in parameters such as the size of the compression cylinder 5 and the stroke of the push assembly 7.

[0079] In the embodiment of the present invention, the first adjusting member 62 and the second adjusting member may be driving elements such as an electric cylinder, a lead screw of a motor 81, a cylinder, etc. respectively.

[0080] like Figure 6 As shown, in an embodiment of the present invention, the probe assembly X also includes a gripping handle 4, which is threadedly connected to the proximal end of the tube body 1, and is provided with an air intake channel 41 for docking with the air guide core 3 and an exhaust outlet channel 42 for leading out the gas in the inner cavity of the tube body 1, the air intake channel 41 is used to be connected to the air outlet channel 5d pipeline, and the exhaust outlet channel 42 is used to discharge the gas from the pressure relief channel 214 into the tube body 1.

[0081] In an embodiment of the present invention, the physical parameters of the device during treatment can be set as follows: the pressure of the capsule on the inner wall of the vagina is set to 1-3 bar, the number of times of a single treatment is 400-1200 times, and the frequency of the shock wave is 1-10 Hz. Furthermore, considering the impact of shock waves on normal cell activity, during treatment, it is preferred to use low pressure and high frequency parameters for treatment, such as 1 bar, 800 times, 1 bar, 1200 times.

[0082] like Figure 2 As shown, in the embodiment of the present invention, an arc-shaped guide cover is provided at the distal end of the tube body 1. The arc-shaped guide cover is provided to facilitate the tube body 1 to extend into the vagina.

[0083] In the embodiment of the present invention, when the device is used for treatment, a layer of rubber film can be disposed outside the tube body 1.

[0084] In the embodiment of the present invention, a support portion is provided on the inner wall of the distal end of the tube body 1, the proximal end of the air guide core 3 is sleeved in the air inlet channel 41, and the distal end of the air guide core 3 is mounted on the support portion. By providing the support portion, the support strength of the connecting branch pipe 31 for the shock wave generator 2 can be increased, and the shock wave generator 2 can be prevented from being difficult to install due to deformation of the air guide core 3 due to force.

[0085] The probe assembly X of the present invention is described below in conjunction with a specific medical treatment process for bacterial vaginosis.

[0086] like Figure 1 and Fig.14 As shown, when treating patients with bacterial vaginosis, medical staff can first insert the tube body 1 into the patient's vagina, and adjust the insertion depth of the tube body 1 according to the different pathological locations of the inflammation. After the position of the tube body 1 is adjusted in place, the medical staff needs to manually input the treatment parameters or select the treatment mode in the display and control terminal of the device. After receiving the corresponding treatment parameter value, the controller will control the first adjustment member 62 to operate to adjust the opening pressure of the pressure relief valve 61 to the specific value corresponding to the treatment parameter. When the controller confirms that the adjustment of the first adjustment member 62 is completed, it will control the second adjustment member to operate accordingly to adjust the position of the cylinder 51 relative to the piston rod 52. After the above adjustment is completed, the gas source generating assembly Z starts and supplies gas to the probe assembly X. At this time, the probe assembly X begins to generate radial shock waves.

[0087] During the treatment process, medical staff can adjust the insertion depth of the tube body 1 and the intensity of the shock wave according to the different pathological locations of the inflammation. Since there are multiple shock wave generators 2, which are distributed at intervals along the circumferential and axial directions, the device can emit multiple shock waves with different phase angles and different axial positions at the same time, thereby increasing the range of shock wave generation. When using it, medical staff only need to slightly rotate the tube body 1 or slightly adjust the insertion depth of the tube body 1 to ensure that the inflamed area of ​​the vaginal wall can be irradiated by the shock wave. When using this device, medical staff can adjust the treatment parameters on the display and control terminal from time to time according to the effect of shock wave treatment. The controller will automatically change the pressure of the pulse gas, the supply frequency of the pulse gas, and the supply duration of the pulse gas according to the treatment parameters, thereby realizing the adjustment of the frequency and intensity of the shock wave, and realizing targeted treatment of different strains and different diseases.
