DETAILED DESCRIPTION

[0027] The specific embodiments of the utility model are described in detail below in combination with the drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the utility model, and are not used to limit the utility model.

[0028] The biological membrane ultrasonic wave destruction device of the utility model is described below with reference to the drawings.

[0029] The utility model provides a kind of biological membrane ultrasonic wave destruction device, as Figure 1 And Figure 2 As shown, biological membrane ultrasonic wave destruction device includes isolation protection pipe 1, ultrasonic wave generating mechanism 2, power supply mechanism and rotating drive mechanism 5.

[0030] Isolation protection pipe 1 is used to extend into the vagina of human body and isolate human body tissue from ultrasonic wave generating mechanism 2.

[0031] Ultrasonic wave generating mechanism 2 includes installation seat 21 that extends into isolation protection pipe 1 and can rotate circumferentially and piezoelectric element 22 that is arranged on installation seat 21, and the ultrasonic wave generating surface of piezoelectric element 22 is perpendicular to cross-sectional direction, that is, piezoelectric element 22 can generate radial direction ultrasonic wave.

[0032] Power supply mechanism is used to supply power to piezoelectric element 22, and different energy density, different frequency ultrasonic wave can be generated by changing the voltage and current of power supply mechanism.

[0033] Rotating drive mechanism 5 is used to drive installation seat 21 to rotate, and the phase of ultrasonic wave in the circumferential direction of isolation protection pipe 1 can be changed by rotating drive mechanism 5, so that the ultrasonic wave generating surface is conveniently aligned with pathological site of vaginal inner wall in radial direction.

[0034] One end of isolation protection pipe 1 is closed end, and the other end is open end, and open end is mainly used for installation seat 21 to extend into, and piezoelectric element 22 can be buzzer for emitting ultrasonic wave, or piezoelectric ceramic sheet, when power supply mechanism applies preset waveform alternating current to both end surfaces of piezoelectric element 22, the type of ultrasonic wave emitted by piezoelectric element 22 can be changed.

[0035] When using the device to treat locally inflamed vagina, isolation protection pipe 1 can be inserted into vagina to appropriate depth first, then rotating drive mechanism 5 is controlled to act, so that installation seat 21 and piezoelectric element 22 rotate in isolation protection pipe 1 by a preset angle, when the ultrasonic wave generating surface of piezoelectric element 22 is radially aligned with inflamed site, rotating drive mechanism 5 is controlled to stop acting, then ultrasonic wave treatment can be carried out, since the device can generate radial direction ultrasonic wave, the treatment effect for vaginitis is better, and during treatment, the phase angle of piezoelectric element 22 can be finely controlled according to demand, so that the ultrasonic wave generating surface is better radially aligned with pathological site.

[0036] When the device is used to treat a vagina with a large inflammation range, the isolation protection tube 1 can be inserted into the vagina to a suitable depth, and the rotating drive mechanism 5 is controlled to drive the piezoelectric element 22 to generate radial ultrasonic waves while rotating. Since the ultrasonic wave generating surface of the piezoelectric element 22 is perpendicular to the cross-sectional direction, the piezoelectric element 22 can radiate ultrasonic waves circumferentially 360° on the inner wall of the vagina every time the mounting seat 21 rotates one revolution, thereby ensuring the comprehensiveness of the radiation range.

[0037] As shown in Figure 2 , Figure 3 and Figure 4 , in the embodiment of the utility model, the mounting seat 21 includes a first plate body 211 and a second plate body 212, the first plate body 211 is provided with a limiting clamping cavity 211a penetrating along the thickness direction, the limiting clamping cavity 211a gradually decreases in size from the inner side of the first plate body 211 to the opposite outer side, the piezoelectric element 22 is installed in the limiting clamping cavity 211a, and the second plate body 212 is attached to the inner side of the first plate body 211 and is used to resist clamping the piezoelectric element 22.

[0038] Specifically, one side of the first plate body 211 facing the second plate body 212 is the inner side, and the other side is the outer side, and the piezoelectric element 22 can be installed from the inner side of the limiting clamping cavity 211a. The existing piezoelectric ceramic sheet is generally provided in the form of a round sheet, so the limiting clamping cavity 211a can be circular. Taking the circular limiting clamping cavity 211a as an example, since the diameter of the limiting clamping cavity 211a gradually decreases from the inner side to the outer side, when the piezoelectric element 22 is installed in the limiting clamping cavity 211a, it will be limited and clamped in the limiting clamping cavity 211a. By attaching the second plate body 212 to the inner side of the first plate body 211, the piezoelectric element 22 can be held and fixed in the limiting clamping cavity 211a, preventing the piezoelectric element 22 from falling out of the inner side opening of the limiting clamping cavity 211a. That is, by clamping the first plate body 211 and the second plate body 212, the installation of the piezoelectric element 22 can be completed.

[0039] In the embodiment of the utility model, the first plate body 211 and the second plate body 212 can be detachably connected through a threaded connection or a buckle structure.

[0040] In the embodiment of the utility model, in the treatment, the physical parameter of the ultrasonic wave emitted by the ultrasonic wave destroying device can be set as: energy density: 0.4-2.0 W / square centimeter; Frequency: 2-4 MHz, preferably 3 MHz. Among them, the device works for a long time, and the heat effect is more likely to occur, in order to avoid the local overheating of the isolation protection tube 1 leading to the burning of the patient's tissue, the device single treatment time is preferably controlled within 5-10 min. For the treatment of local inflammation, the setting logic of the device physical parameter is to reduce the energy density of the ultrasonic wave and increase the working time of the ultrasonic wave. According to the laboratory test, the killing rate of the inflammation bacteria of the ultrasonic wave with 0.4 W / square centimeter energy density acting on the inflammation area for 10 minutes is higher than that of the ultrasonic wave with 1.0 W / square centimeter and 2.0 W / square centimeter.

[0041] For the treatment of large area of vaginitis, the piezoelectric element 22 is always rotating during treatment, in order to ensure the treatment efficiency, the ultrasonic wave with large energy density can be selected for treatment, and the treatment time can be set according to the thickness of the bacterial membrane generated by inflammation.

[0042] As shown in Figure 2 and Figure 3 In the embodiment of the utility model, the outer side of the first plate body 211 is also provided with a horn 23, and the horn 23 is arranged on the limiting clamping cavity 211a. The horn 23 can bundle the ultrasonic wave, so that the energy of the ultrasonic wave is more concentrated. Preferably, the outlet of the horn 23 extends in the radial direction.

[0043] As shown in Figure 2 , Figure 3 and Figure 4 In the embodiment of the utility model, the number of limiting clamping cavities 211a on the first plate body 211 can be multiple, and the multiple limiting clamping cavities 211a are arranged along the rotation center axis direction of the mounting seat 21. Correspondingly, the number of piezoelectric elements 22 and horns 23 is also multiple, and the number of piezoelectric elements 22, horns 23 and limiting clamping cavities 211a corresponds one by one. Since the device of the utility model is mainly used for the treatment of vaginitis, in order to ensure the comfort of treatment, the overall size of the device is small, and the size of the piezoelectric element 22 used is also very small. After the ultrasonic wave emitted by a single piezoelectric element 22 is bundled by the horn 23, the axial width of the irradiation is limited. In order to increase the breaking efficiency of the biofilm, multiple piezoelectric elements 22 can be arranged to break the biofilm at different depths of the vagina at the same time.

[0044] As shown in Figure 2As shown in the embodiment of the utility model, the number of the first plate body 211 can be two, and the second plate body 212 can be clamped between the two first plate bodies 211. By arranging two groups of first plate bodies 211, the same position of the vaginal wall can be radiated by ultrasonic waves twice when the mounting seat 21 rotates one round.

Specifically, still taking the piezoelectric ceramic sheet as an example, one end face of the piezoelectric ceramic sheet is used for electrically connecting with the positive electrode conductive wire, and the other end face is used for electrically connecting with the negative electrode conductive wire. Since the inner side of the second plate body 212 is attached and compressed with the first plate body 211, it is only necessary to clamp the positive electrode conductive sheet 31 between the first plate body 211 and the second plate body 212, and make the positive electrode conductive sheet 31 contact with the inner side of the piezoelectric ceramic sheet under the action of the clamping force, so that one end face of the piezoelectric ceramic sheet is used for electrically connecting with the positive electrode conductive wire. Similarly, by arranging the negative electrode conductive sheet, the other end face of the piezoelectric ceramic sheet is realized to be conductive.

[0046] In the embodiment of the utility model, the negative electrode conductive wire can also be electrically connected with the positive electrode conductive sheet 31, and the positive electrode conductive wire is connected with the negative electrode terminal of the piezoelectric element 22.

[0049] Specifically, the handle hollow cavity is a cylindrical cavity, a ring-shaped positive metal sheet 34 and a ring-shaped negative metal sheet 35 are arranged on the cavity inner wall of the handle hollow cavity, the ring-shaped positive metal sheet 34 and the ring-shaped negative metal sheet 35 are staggered in the axial direction of the cylindrical cavity, the positive contact terminal 32 and the negative contact terminal 33 are further led out from the end of the second plate body 212, the positive contact terminal 32 is arranged in a bent manner and the end thereof is in contact with the ring-shaped positive metal sheet 34, the negative contact terminal 33 is also arranged in a bent manner and the end thereof is in contact with the ring-shaped negative metal sheet 35, the ring-shaped positive metal sheet 34 and the ring-shaped negative metal sheet 35 are connected with the positive and negative poles of an external power supply, and through the abutment of the metal sheets and the contact terminals, the piezoelectric element 22 can be continuously powered when the mounting seat 21 rotates.

[0050] In the embodiment of the utility model, the end of the positive contact terminal 32 and the negative contact terminal 33 is further provided with an elastic metal contact sheet, so that the contact between the metal sheet and the contact terminal is better maintained.

[0051] As shown in Figure 1 In the embodiment of the utility model, the rotary driving mechanism 5 comprises a driving motor 51 mounted on the inner wall of the handle hollow cavity and a transmission assembly 52 transmissionally connected between the driving motor 51 and the mounting seat 21.

[0052] As shown in Figure 1 and Figure 2 In the embodiment of the utility model, the transmission assembly 52 can comprise a transmission ring 521 and an engagement end cover 522, the inner side of the transmission ring 521 is provided with a clamping fixing piece 523 for clamping and fixing the mounting seat 21, the outer side of the transmission ring 521 is provided with a transmission gear, the engagement end cover 522 is sleeved on the outer side of the transmission ring 521 and is in engagement with the transmission gear, and the output shaft of the driving motor 51 is in transmission connection with the engagement end cover 522. The clamping fixing piece 523 can be fixedly connected with the mounting seat 21 in a clamping groove clamping manner, so that the mounting seat 21 can be driven to rotate together with the transmission ring 521 when the transmission ring 521 rotates, or the transmission ring 521 can be fixedly connected with the mounting seat 21 through a connecting piece, the peripheral wall of the engagement end cover 522 is provided with an extension hole for the positive contact terminal 32 and the negative contact terminal 33 to extend radially, and the positive contact terminal 32 and the negative contact terminal 33 can extend out of the extension hole and extend to the ring-shaped positive metal sheet 34 and the ring-shaped negative metal sheet 35 on the cavity wall of the handle hollow cavity, respectively. In use, only the driving motor 51 needs to be operated, so that the mounting seat 21 can be circumferentially rotated in the isolation protection pipe 1, and the holding handle 4 is arranged, so that medical staff can hold the biological membrane ultrasonic wave destruction device during treatment.

[0055] In the embodiment of the utility model, by replacing the isolation protection tube 1 with different diameters or the isolation protection tube 1 with different shapes, the device can better adapt to patients with different body types.

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

[0057] For patients with bacterial vaginosis, medical staff can first insert the isolation protection tube 1 into the vagina of the patient when treating, and adjust the insertion depth of the isolation protection tube 1 according to the pathological position of inflammation. After the position of the isolation protection tube 1 is adjusted, the driving motor 51 is controlled to rotate, and the power supply is controlled to supply power, the piezoelectric element 22 generates ultrasonic waves after being powered, the ultrasonic waves are concentrated by the beam wave of the amplitude changer 23, and are emitted to the pathological part in a radial direction or circumferentially at 360°, so as to ensure that the piezoelectric element 22 can vertically irradiate the inner wall of the vagina in a targeted or larger range, and in the process of operation of the device, the emission position of the piezoelectric element 22 can be adjusted in the depth direction by further changing the insertion depth of the isolation protection tube 1, so as to ensure that all target regions of the inner wall of the vagina can be irradiated by ultrasonic waves.
