[0034] The inventors have found that the use of vaginal molds is a very important part of postoperative treatment for vaginoplasty. Vaginal molds need to be placed for 3-6 months after surgery to prevent vaginal stenosis, adhesion, shortening and reocclusion after artificial vaginoplasty. Existing vaginal molds are usually unable to collect vaginal secretions and perform regular flushing, which can easily cause reproductive tract infections in patients.

[0035] Based on the above findings, the present application provides a vaginal mold for use after peritoneal vaginoplasty, including a mold body 1, an extension component 2 is slidably provided in the center of the mold body 1, and a cleaning component 3 is provided in the side wall of the mold body 1, and the cleaning component 3 is used for collecting and flushing metabolites in the vagina.

[0036] Embodiment 1 Reference Figure 1-13 As shown, the present application provides a vaginal mold for use after peritoneal vaginoplasty, including a mold body 1, an extension component 2 is slidably provided in the center of the mold body 1, and a cleaning component 3 is provided in the side wall of the mold body 1, and the cleaning component 3 is used for collecting and flushing metabolites in the vagina.

[0037] Furthermore, the mold body 1 includes a mold sleeve 11 , and two installation cavities 12 that penetrate vertically are symmetrically opened on the wall of the mold sleeve 11 , and the cleaning component 3 is arranged in the installation cavity 12 .

[0038] The mold sleeve 11 is placed in the vagina, and the mold sleeve 11 is used to expand and support the vagina.

[0039] Furthermore, the inner wall of the mold sleeve 11 is provided with a movable groove 13 and a plurality of clamping grooves 14 , and the extension component 2 includes an extension portion 21 and an operating portion 22 , and the operating portion 22 cooperates with the movable groove 13 and the clamping groove 14 to achieve position limitation of the extension portion 21 .

[0040] Specifically, the extension portion 21 includes an extension rod 211 , an extension column 212 is connected to the extension rod 211 , a dome cover 213 is provided at the end of the extension column 212 , and the radius of the dome cover 213 matches the radius of the mold sleeve 11 .

[0041] It should be noted that the configuration of the dome cover 213 structure avoids damaging the tissue inside the vagina when the extension portion 21 is sleeved in the mold sleeve 11 and pushed into the vagina.

[0042] In detail, the extension component 2, on the one hand, plays a technical role in supporting the mold sleeve 11, and on the other hand, enables the vaginal mold to be suitable for patients with different vaginal depths, effectively expands the vagina, and prevents patients from experiencing vaginal stenosis, adhesions, shortening of length, and re-closure after vaginoplasty.

[0043] In particular, the operating part 22 includes two fixed disks 221 arranged on the extension rod 211, each of the fixed disks 221 is connected to a rotating disk 222, and the rotating disk 222 is connected to a plurality of corresponding blocks 223 and gears 224 through a rotating shaft, and the blocks 223 cooperate with the slots 14, and the gears 224 mesh with the toothed disk 225.

[0046] Specifically, there are two operating rods 226 .

[0047] During the specific operation, according to the specific conditions of the patient's vagina, the extension rod 211 and the extension column 212 are sleeved in the corresponding positions in the mold sleeve 11, and the operating rod 226 is further rotated to drive the rotation of the rotating disk 222, and the rotating disk 222 drives the rotation of the gear 224 and the toothed disk 225 to achieve the unscrewing of the card block 223, so that the unscrewed card block 223 is clamped with the card groove 14 set on the inner wall of the mold sleeve 11, and finally the technical effect of the sleeve fixation between the extension component 2 and the mold sleeve 11 is achieved.

[0048] When the position of the extension component 2 needs to be adjusted again, the operating rod 226 is rotated in the opposite direction, thereby driving the rotation of the rotating disk 222, and further driving the rotation of the gear 224 and the toothed disk 225 through the rotating disk 222, thereby realizing the screwing of the block 223, and then releasing the engagement between the block 223 and the slot 14, and finally realizing the movement of the extension component 2 in the mold sleeve 11.

[0049] It should be noted that the operating rod 226 is limited to rotate within the range of the movable groove 13, and the limiting groove 228 limits the limiting column 227 to achieve the rotation angle of the block 223.

[0050] Furthermore, the cleaning assembly 3 includes a cleaning sleeve 31, and two dirt collecting grooves 32 are symmetrically opened on the wall of the cleaning sleeve 31 and penetrated vertically. A piston barrel 33 is movably arranged in the dirt collecting groove 32, and a piston plate 34 is arranged in the piston barrel 33. The piston plate 34 is fixed to the cleaning sleeve 31 by a pull rope 35.

[0051] Preferably, a handle 39 is provided on the piston barrel 33 , and the handle 39 is pulled to drive the piston barrel 33 to move relative to the piston plate 34 , thereby achieving the technical effect of sucking and spraying the flushing liquid in the piston barrel 33 .

[0052] Embodiment 2 On the basis of the first embodiment, in order to collect the metabolites produced in the vagina and prevent the metabolites from flowing back, a one-way valve 36 and a blocking piece 37 are provided in the sewage collecting tank 32 , and the blocking piece 37 is connected to the piston barrel 33 through a fixing frame 38 .

[0053] It should be noted that, by disposing the fixing frame 38 , the blocking piece 36 and the piston barrel 33 can move synchronously.

[0054] Specifically, the provision of the one-way valve 36 can effectively prevent the metabolites from flowing back into the sump 32 .

[0055] Furthermore, in order to better fix the guide mold, a vaginal mold for use after peritoneal vaginoplasty also includes a fixing pants 4, on which a fixing plate 41 is provided, and the fixing plate 41 is connected to the mold sleeve 11.

[0056] Connecting and fixing the mold sleeve 11 through the fixing piece 41 arranged on the fixing pants 4 can effectively avoid the technical problem of the vaginal mold falling off. Fixing it through the fixing pants 4 makes it easy to put on and take off, and can ensure the expansion support effect after vaginal plasty.

[0057] Specific application cases: Congenital absence of vagina is an abnormal development of the vagina. It is a congenital developmental defect caused by the stagnation of the development of the paramesonephric duct or the tail end of the paramesonephric duct and its failure to extend downward. It is mainly manifested as primary amenorrhea. Vaginoplasty is one of the methods to treat congenital absence of vagina syndrome. Through surgical treatment, top pressure is formed to form a suitable vaginal length or create an artificial new vagina. After the operation, a vaginal mold needs to be placed to help expand the vagina to prevent vaginal stenosis, adhesion, shortening of length, and re-closure. However, common vaginal molds cannot discharge vaginal secretions, which can cause reproductive tract infections in patients; in addition, common vaginal molds have poor applicability and cannot meet the use needs of patients after different vaginoplasty operations.

[0058] Based on this, the present application provides a vaginal mold for peritoneal vaginoplasty. In the specific use process: the medical staff holds the handle 39, pulls the handle 39 to drive the piston barrel 33 to move relative to the piston plate 34, and then realizes the suction of the flushing liquid in the piston barrel 33; The cleaning sleeve 31 filled with flushing liquid is inserted into the mounting cavity 12 of the mold sleeve 11 , and the extension assembly 2 is further assembled into the mold sleeve 11 .

[0059] Specifically, the extension rod 211 and the extension column 212 are sleeved in the corresponding positions in the mold sleeve 11, and the operating rod 226 is further rotated to drive the rotating disk 222 to rotate, and the rotating disk 222 drives the gear 224 and the toothed disk 225 to rotate and cooperate, thereby realizing the unscrewing of the clamping block 223, so that the unscrewed clamping block 223 is clamped with the clamping groove 14 set on the inner wall of the mold sleeve 11, and finally the sleeve fixation between the extension component 2 and the mold sleeve 11 is realized.

[0060] Furthermore, the dome cover 213 and the extension column 212 are connected and fixed to realize the assembly of the overall vaginal mold.

[0061] The assembled vaginal mold is fixed to the fixing pants 4 via the fixing plate 41 and then inserted into the patient's vagina.

[0062] The mold needs to be cleaned after being placed for a period of time, and the metabolites in the vagina enter the sewage collection tank 32 through the sewage inlet 214 and the one-way valve 36.

[0063] The handle 39 is pushed to drive the piston barrel 33 to move relative to the piston plate 34 , so that the flushing liquid in the piston barrel 33 is sprayed out to flush and clean the mold sleeve 11 .

[0064] It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The protection scope required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
