DETAILED DESCRIPTION

[0026] The specific embodiments described hereinbelow with reference to the drawings should be understood to be merely illustrative and explanatory of the present application, and not to be restrictive of the present application.

[0027] The biological membrane shock wave probe device of the present application is described below with reference to the drawings.

[0028] The present application provides a biological membrane shock wave probe device, as shown in Figure 1 and Figure 2 The biological membrane shock wave probe device comprises:

[0029] The pipe body 1 is closed at the distal end and open at the proximal end, and the shock wave generation channel 11 closed by the isolation film 12 is inlaid on the peripheral wall of the pipe body 1;

[0030] The pneumatic shock wave generator 2 is arranged in the shock wave generation channel 11 and located at the inner side of the isolation film 12, and the shock wave generation end of the shock wave generator 2 is arranged radially towards the isolation film 12;

[0031] The air guide pipe core 3 is arranged in the pipe body 1, the distal end of the air guide pipe core 3 is closed, and the proximal end is provided with an air inlet, and the connecting branch pipe 31 for interfacing with the shock wave generator 2 is arranged on the peripheral wall of the air guide pipe core 3, and the air guide pipe core 3 sequentially provides high-pressure air to the shock wave generator 2 through the connecting branch pipe 31.

[0032] When the device is used to treat the vagina, the pipe body 1 can be inserted into the vagina first, and then high-pressure air is sequentially provided to the shock wave generator 2 through the air guide pipe core 3, the high-pressure air can drive the shock wave generator 2 to generate a shock wave towards the peripheral wall direction (radial direction) of the pipe body 1, and after the shock wave acts on the isolation film 12, the transmission through the isolation film 12 will act on the inner wall of the vagina, thereby achieving the destruction of the bacterial biofilm on the inner wall of the vagina. In summary, the device can generate radial direction ultrasonic waves, thereby being more suitable for the treatment of vaginosis.

[0033] As shown in Figure 1As shown in the embodiment of the utility model, the number of shock wave generation channels 11 and shock wave generators 2 is multiple respectively, multiple shock wave generators 2 are set up one by one with multiple shock wave generation channels 11 respectively, and the gas guide pipe core 3 can supply gas to the shock wave generators 2 in all shock wave generation channels 11 simultaneously. That is, the device can generate radial shock waves at multiple positions of the pipe body 1, thereby increasing the range of shock wave generation. For patients with a larger inflamed area in the vagina, medical personnel only need to slightly rotate the pipe body 1 or slightly adjust the insertion depth of the pipe body 1 when using, so as to ensure that the inflamed area of the inner wall of the vagina can be irradiated by the shock wave.

[0034] In the embodiment of the utility model, multiple connecting branch pipes 31 are arranged on the peripheral wall of the gas guide pipe core 3, and the connecting branch pipes 31 are used for one-to-one connection with the shock wave generators 2. In the process of flowing from the proximal end of the gas guide pipe core 3 to the distal end of the gas guide pipe core 3, the connecting branch pipes 31 divide the gas of the gas guide pipe core 3, and the gas pressure in the gas guide pipe core 3 is reduced by a part; in order to ensure that the gas pressure in the gas guide pipe core 3 is the same when the gas is divided to each connecting branch pipe 31 (that is, to ensure that each shock wave generator 2 can generate the same size shock wave), in the embodiment of the utility model, the lumen cross-sectional area of the gas guide pipe core 3 can be gradually smaller from the proximal end to the distal end, that is, the gas guide pipe core 3 has a structure of thick proximal end and thin distal end.

[0035] Based on the above design, as shown in Figure 1 and Figure 3 in order to facilitate the guarantee of the gas pressure between different connecting branch pipes 31, in the embodiment of the utility model, the gas guide pipe core 3 can include multiple gas guide pipe sections connected in sequence from the proximal end to the distal end, the farthest gas guide pipe section is blocked by the solid pipe core, at least one connecting branch pipe 31 is arranged on the peripheral wall of each gas guide pipe section, the connecting branch pipe 31 is used for one-to-one connection with the shock wave generator 2, and the lumen cross-sectional area of the proximal end gas guide pipe section is greater than that of the distal end gas guide pipe section between any adjacent gas guide pipe sections.

[0036] Further, in the embodiment of the utility model, the ratio of the cross section Si of the proximal end gas guide pipe section to the cross section Si+1 of the distal end gas guide pipe section between any adjacent gas guide pipe sections approximately meets Si:Si+1=ΣAi:ΣAi+1, and a certain error is allowed; wherein i represents the i-th gas guide pipe section counted from the proximal end of the gas guide pipe core 3, i+1 represents the gas guide pipe section adjacent to the i-th gas guide pipe section and closer to the distal end, Si represents the cross-sectional area of the i-th gas guide pipe section, Si+1 represents the cross-sectional area of the i+1-th gas guide pipe section, ΣAi represents the total number of connecting branch pipes 31 from the i-th gas guide pipe section to the farthest gas guide pipe section, and ΣAi+1 represents the total number of connecting branch pipes 31 from the i+1-th gas guide pipe section to the farthest gas guide pipe section.

[0037] Taking the trisectional trachea core 3 composed of three trachea sections as an example, it is assumed that three connecting branch pipes 31 are connected to the circumferential wall of each trachea section, at this time, the trachea section closest to the proximal end is taken as the first trachea section, and the ratio of the cross-sectional area of the first trachea section to the cross-sectional area of the adjacent second trachea section satisfies S1:S2=(3*3):(2*3)=3:2.

[0038] As shown in the drawings, Figure 3 In the embodiment of the utility model, transition connecting portions 32 in arc transition are formed between any adjacent trachea sections, one end of the connecting branch pipe 31 is a branch pipe air inlet end, the other end is a branch pipe air outlet end, the branch pipe air inlet end is connected to the transition connecting portion in axial extension (i.e. the direction of the trachea core), the branch pipe air outlet end extends radially towards the corresponding shock wave generation channel 11, and the connecting branch pipe 31 is in arc transition from the branch pipe air inlet end to the branch pipe air outlet end. The transition connecting portion 32 and the arc transition can guide the flow of gas, avoiding a large amount of loss of gas pressure due to gas shunting or gas flow turning.

[0039] In the embodiment of the utility model, the connecting branch pipe 31 and the shock wave generation channel 11 correspond in number and are radially aligned in position, and the connecting branch pipe 31 is used to radially butt against the shock wave generator 2 in the radially aligned shock wave generation channel 11. By radially butting the connecting branch pipe 31 against the shock wave generator 2, the direction of the gas finally flowing into the shock wave generator 2 can be made to be the same as the direction of the shock wave generation, so that the shock wave generator 2 can generate a radial shock wave with greater energy.

[0040] Specifically, as shown in the drawings, Figure 1 , Figure 2 and Figure 4 In the embodiment of the utility model, the shock wave generator 2 includes a gas guide cover 21, a striking member 22 and a reset member 23, the gas guide cover 21 is limitingly installed in the shock wave generation channel 11 and an inside of the gas guide cover 21 forms a shock wave generation cavity 211, the striking member 22 is arranged in the shock wave generation cavity 211, the shock wave generation cavity 211 is provided with an outer end opening 211a radially outward and an inner end opening 211b radially inward, the connecting branch pipe 31 is used to radially butt against the inner end opening 211b detachably, the circumferential wall of the gas guide cover 21 is further provided with a pressure relief channel 214 communicating with the inner cavity of the pipe body 1, the pressure relief channel 214 is located between the outer end opening 211a and the inner end opening 211b and is used to communicate the inner end opening 211b with the inner cavity of the pipe body 1 when the striking member 22 moves a preset distance towards the outer end opening 211a, and the reset member 23 is used to drive the striking member 22 to move towards the inner end opening 211b when the gas pressure in the trachea core 3 is lower than a preset value, so as to cut off the channel between the pressure relief channel 214 and the inner end opening 211b.

[0041] The way of providing high-pressure gas between the air guide tube cores 3 can be to provide gas at the rhythm of high pressure-low pressure-high pressure-low pressure, or to provide gas at the rhythm of high pressure-negative pressure-high pressure-negative pressure. When the gas in the air guide tube core 3 is high pressure, the pressure of the gas needs to be much greater than the driving force of the reset member 23, so that the impact member 22 can be accelerated instantaneously, quickly impact the isolation membrane 12, ensure the energy intensity of the shock wave, and when the impact member 22 moves to the preset distance of the outer end opening 211a, the pressure relief channel 214 can be used to release the excess gas in the air guide tube core 3 through the pressure relief channel 214, thereby reducing the gas pressure in the air guide tube core 3 and ensuring the quick reset of the impact member 22 by the reset member 23. When the gas in the air guide tube core 3 is low pressure or negative pressure, the reset member 23 drives the impact member 22 to reset to the position of blocking the inner end opening 211b, so that when the air guide tube core 3 provides high-pressure gas in the next cycle, the energy of the high-pressure gas can act more on the reset member 23, ensuring effective energy transmission. When the air guide tube core 3 provides gas at the rhythm of high pressure-negative pressure-high pressure-negative pressure, the driving force generated by the negative pressure can speed up the reset rate of the reset member 23, thereby achieving the purpose of increasing the frequency of the shock wave.

[0042] As shown in Figure 1 , Figure 2 and Figure 4 , in the embodiment of the utility model, the air guide cover 21 includes a cone part 215 and a pipe part 216, the pipe part 216 is connected with the small mouth of the cone part 215, the big mouth of the cone part 215 is the outer end opening 211a of the shock wave generating cavity 211, the opening of the end of the pipe part 216 away from the cone part 215 is the inner end opening 211b, and the end of the pipe part 216 away from the cone part 215 is used to be detachably connected with the connecting branch pipe 31 in the radial direction, wherein the detachable connection between the pipe part 216 and the connecting branch pipe 31 can be realized by a buckle structure or a threaded connection. One end of the impact member 22 is located in the lumen of the pipe part 216, and the other end is used to extend into the inner cavity of the cone part 215 when the impact member 22 moves to the preset stroke towards the cone part 215, and the pipe part 216 is used to guide the radial movement of the impact member 22 towards the cone part 215.

[0043] As shown in Figure 1 and Figure 2 , when the device is installed, after the air guide tube core 3 is inserted into the pipe body 1, the connecting branch pipe 31 is first aligned with the shock wave generating channel 11 by rotating the air guide tube core 3, and then the shock wave generator 2 is inserted from the outside of the shock wave generating channel 11, so that the pipe part 216 of the shock wave generator 2 is connected with the connecting branch pipe 31 by clamping or threaded connection, and the air guide cover 21 is limited by the inner wall of the shock wave generating channel 11 and the limiting of the connecting branch pipe 31 and the pipe part 216, thereby completing the quick installation of the shock wave generator 2. Through the above setting, the quick installation and removal function of the air guide tube core 3 and the shock wave generator 2 can be realized, and the replacement of the subsequent vulnerable parts is facilitated.

[0044] As Figure 4 shown in the embodiment of the utility model, the limit step 212 is further arranged between the cone body part 215 and the catheter part 216, the impact piece 22 includes the plug body part 221 and the rod body part 222, the plug body part 221 is located in the lumen of the catheter part 216, one end of the rod body part 222 is connected with the plug body part 221, and the other end is used to pass through the limit step 212 and impact the isolation film 12 located at the outer end opening 211a when the impact piece 22 moves the preset stroke towards the cone body part 215, by arranging the catheter part 216, the radial movement path of the impact piece 22 can be guaranteed, and then the impact piece 22 can accurately impact the specified area of the isolation film 12 each time.

[0045] In the embodiment of the utility model, the plug body part 221 can be provided with a through hole, and the through hole can guarantee that the plug body part 221 resets below the pressure relief channel 214 under the action of the elastic member. Among them, the hole diameter of the through hole needs to be set as a small hole to reduce the pressure loss of the pulse gas.

[0046] As Figure 4 shown in the embodiment of the utility model, the reset member 23 is an elastic member and is arranged between the limit step 212 and the plug body part 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 plug body part 221, the rapid reset of the impact piece 22 can be realized.

[0047] As Figure 1 and Figure 4 shown in the embodiment of the utility model, the shock wave generator 2 further includes a uniform vibration metal sheet 242, the uniform vibration metal sheet 242 is attached to the radial inner side of the isolation film 12 and closes the outer end opening 211a, and the rod body part 222 uniformly radiates impact force to the isolation film 12 through the uniform vibration metal sheet 242. By arranging the uniform vibration metal sheet 242, the vibration generated by the rod body part 222 can be more uniformly radiated on the surface of the isolation film 12, so that the uniformity of the shock wave energy is guaranteed.

[0048] As Figure 1 and Figure 4 shown in the embodiment of the utility model, the gas pressure balance channel 213 is arranged on the conical side wall of the cone body part 215, and the gas pressure balance channel 213 communicates the inner cavity of the tube body 1 and the inner cavity of the cone body part 215. By arranging the gas pressure balance channel 213, the high-pressure gas can drive the impact piece to work normally, and the kinetic energy loss of the impact piece 22 caused by the excessive pressure in the inner cavity of the cone body part 215 can be avoided.

[0049] In the embodiment of the utility model, the isolation film 12 can be a capsule, and the capsule is filled with liquid medium. By filling different media in the capsule, 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 generation channel 11 by means of glue bonding. When the glue is bonded, the sealing between the capsule and the peripheral wall of the pipe body 1 needs to be ensured.

[0050] As shown in Figure 1 and Figure 5 In the embodiment of the utility model, the biofilm shock wave probe device further comprises a holding handle 4, the holding handle 4 is screwed at the proximal end of the pipe body 1, and the holding handle 4 is provided with an air inlet introduction channel 41 for butting with the air guide pipe core 3 and an air outlet introduction channel 42 for leading out the gas in the inner cavity of the pipe body 1.

[0051] In the embodiment of the utility model, the inner wall of the distal end of the pipe body 1 is provided with a support part, the proximal end of the air guide pipe core 3 is sleeved in the air inlet introduction channel 41, and the distal end of the air guide pipe core 3 is installed on the support part. By providing the support part, the support strength of the connecting branch pipe 31 to the shock wave generator 2 can be increased, and the difficulty of installing the shock wave generator 2 due to the deformation of the air guide pipe core 3 under stress can be avoided.

[0052] To achieve the above object, the utility model also provides a kind of shock wave treatment equipment, wherein, shock wave treatment equipment includes the biofilm shock wave probe device according to above and gas source generator, and gas source generator is used to intermittently supply gas to biofilm shock wave probe device. The flow of pulse gas provided by gas source generator each time needs to be greater than the gas pressure relief flow of all pressure relief channels in pipe body, to ensure the normal operation of equipment. Since shock wave treatment equipment adopts all technical solutions in the above embodiment, it at least has all the technical effects brought by the above embodiment, which will not be repeated here.

[0053] In the embodiment of the utility model, the physical parameters of the device during treatment can be set as follows: the pressure of the capsule acting on the inner wall of the vagina is set to 1-3bar, the number of actions for single treatment is 400-1200 times, and the frequency of shock wave generation is 1-10Hz. Further, considering the influence of shock wave on normal cell activity, low pressure and high frequency parameters are preferably used for treatment during treatment, such as 1bar, 800 times, 1bar, 1200 times.

[0054] As shown in Figure 1 In the embodiment of the utility model, the distal end of the pipe body 1 is provided with an arc-shaped guide cover. By providing the arc-shaped guide cover, the pipe body 1 can be conveniently inserted into the vagina.

[0055] In the embodiment of the utility model, when using the device for treatment, a layer of rubber film can be further provided on the pipe body 1.

[0056] The biological membrane shock wave probe device of the utility model will be described below in combination with the specific medical process of bacterial vaginosis.

[0057] As shown in Figure 1 For patients suffering from bacterial vaginosis, the pipe body 1 can be inserted into the vagina of the patient first when treatment is performed, and the insertion depth of the pipe body 1 is adjusted according to the pathological position of inflammation. After the position of the pipe body 1 is adjusted in place, the shock wave generator 2 can generate radial shock waves by supplying gas to the gas guide pipe core 3. Since the number of shock wave generators 2 is multiple and is distributed in the circumferential and axial directions, the device can emit multiple beams of shock waves with different phase angles and different axial positions at the same time, thereby increasing the range of shock wave generation. When used by medical personnel, the inflamed area on the inner wall of the vagina can be ensured to be irradiated by the shock wave by slightly rotating the pipe body 1 or slightly adjusting the insertion depth of the pipe body 1. The device can change the frequency and energy density of the shock wave by changing the pressure of the gas pressure and the pulse interval time, thereby realizing targeted treatment of different bacteria.

[0058] In the embodiment of the utility model, when the shock wave is generated by electric energy, the frequency and energy density of the shock wave can be adjusted by changing the size and frequency of the current.
