Description

Technical Field

[0001] The present invention belongs to the field of medical devices, and in particular relates to a vagina shaping device. Background Art

[0002] Vaginal septum syndrome is a congenital malformation of the female reproductive system, typically caused by abnormal fusion of the paramesonephric ducts during embryonic development. It manifests as the formation of an oblique septum within the vagina, dividing it into two compartments: a normal vaginal cavity on one side and an atretic cavity on the other. Menstrual blood in the atretic cavity cannot drain properly and may accumulate, forming a hematocyst. In these cases, surgical excision of the septum is necessary. After excision, vaginal shaping devices are used to dilate the excision site to prevent re-adhesion.

[0003] The utility model patent CN209751304U discloses a "post-vaginoplasty mold", which specifically discloses that the vagina is expanded by a cylindrical body. However, the oblique septum in the oblique vaginal septum syndrome is not located in the middle of the vagina, and simply using the cylindrical body cannot expand the oblique upper septum resection position.

[0019] The following describes the implementation of the present invention through specific embodiments. People skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0020] See also Figures 1 to 12 . It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention. Therefore, they have no substantive technical significance. Any modification of the structure, change in the proportional relationship or adjustment of the size should still fall within the scope of the technical content disclosed by the present invention without affecting the efficacy and purpose that can be achieved by the present invention. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the present invention. Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of the present invention without substantially changing the technical content.

[0021] The following embodiments are for illustration only and can be combined with each other, and are not limited to the contents presented in the following single embodiments.

[0022] See also Figures 1 to 12 The present invention provides a vaginal shaping device, the vaginal shaping device comprising: The first tube 101, The second tube 201 is rotatably mounted on the top surface of the first tube 101. The rotation axis of the second tube 201 is perpendicular to the axis of the first tube 101. The axis of the first tube 101 and the axis of the second tube 201 are located in the same plane. A first rotating shaft is fixedly mounted on the bottom end surface of the second tube 201, and the first rotating shaft is rotatably connected to the top end surface of the first tube 101; A third tube 301 is rotatably mounted on an end of the second tube 201 away from the first tube 101. The axis of the third tube 301 coincides with the axis of the second tube 201, and the third tube 301 rotates around its axis. In this embodiment, the outer diameters of the first tube 101, the second tube 201, and the third tube 301 may be set to be the same; A plurality of wound expansion units are arranged in a circular array along the axis of the third tube 301. The wound expansion units all include a support rod 401, and the support rod 401 is rotatably mounted on the third tube 301. There is a gap between the support rods 401 of adjacent wound expansion units. The support rods 401 of the plurality of wound expansion units are inserted into the diaphragm wound 802 and rotated to expand the diaphragm wound 802.

[0023] After septum resection is performed on a patient with vaginal oblique septum syndrome, there will be a septum wound 802 at the septum resection site. Then the first tube 101, the second tube 201 and the third tube 301 are all inserted into the patient's vagina 801, and the top of the support rod 401 is located above the septum wound 802. Since the septum wound 802 is located on the side directly above the vagina 801, the second tube 201 is rotated at this time and several support rods 401 are aligned with the outline of the septum wound 802. At this time, the support rods 401 are rotated outward so that the support rods 401 can open the septum wound 802.

[0024] In this embodiment, in order to facilitate the installation of the first tube 101, the second tube 201 and the third tube 301 in the patient's vagina 801, during installation, a micro camera can also be placed into the patient's vagina 801 through the first tube 101, the second tube 201 and the third tube 301, so that operation can be facilitated. After the first tube 101, the second tube 201, the third tube 301 and the support rod 401 are installed, the micro camera can be taken out.

[0025] In this embodiment, please refer to Figures 1 to 12 , the gap between the support rods 401 of adjacent wound expansion units is a, the diameter of the support rod 401 is b, a>b.

[0026] Since the diaphragm wound 802 will heal over time, if the support rod 401 remains in the same position during the healing process of the diaphragm wound 802, the support rod 401 and the diaphragm wound 802 will grow into one. When the support rod 401 is removed, the healed diaphragm wound 802 will split again.

[0027] In the present application, since a larger distance is set between adjacent support rods 401, after the support rod 401 has stretched the diaphragm wound 802 for a period of time, the support rod 401 can be rotated away from the original stretched position by rotating the third tube 301 (which can be rotated once every 8 hours), thereby avoiding the support rod 401 from being in contact with the same position of the diaphragm wound 802 for a long time, thereby preventing the support rod 401 from growing into one with the diaphragm wound 802.

[0028] In this embodiment, please refer to Figures 1 to 12The vagina shaping device further includes a rotation assembly for driving the third tube 301 to rotate, and the rotation assembly includes a first slide groove 302, a first slider 303, a first through hole 304, a first spring 305, a connecting rod 306, a first pull wire 307, a guide plate 308 and a guide hole 309; The first chute 302 is annularly provided on the inner wall of the second tube 201 , and the center of the first chute 302 is located on the center line of the second tube 201 ; The first slider 303 is slidably mounted in the first slide groove 302 , and the first through hole 304 passes through the upper and lower end surfaces of the first slider 303 ; The first spring 305 is located in the first sliding groove 302, one end of the first spring 305 is fixedly connected to the first slider 303, and the other end of the first spring 305 is fixedly connected to the inner wall of the first sliding groove 302; One end of the connecting rod 306 is fixedly connected to the first slider 303 , and the other end of the connecting rod 306 is fixedly connected to the third tube 301 ; The guide plate 308 is located below the first chute 302 and is fixedly mounted on the inner wall of the second tube 201 . The guide hole 309 passes through the upper and lower end surfaces of the guide plate 308 . One end of the first pull wire 307 is fixedly mounted on the inner wall of the second tube 201. The first pull wire 307 is mounted on the second inner tube at a first intersection point, which is located above the first chute 302. The other end of the first pull wire 307 passes through the first through hole 304 and the guide hole 309 in sequence. That is, when the first slider 303 does not move, the first pull line 307 between the first intersection and the first through hole 304 is V-shaped; When the first sliding block 303 is located at the sliding starting point, the first intersection point and the guide hole 309 are both located at the sliding front of the sliding direction.

[0029] When the position of the support rod 401 needs to be changed, it can be achieved by rotating the third tube 301. At this time, the first pull wire 307 is pulled, so that the first slider 303 can slide forward along the annular first slide groove 302 (that is, the first slider 303 moves in the direction close to the first intersection). Since the first slider 303 is fixedly connected to the third tube 301 through the connecting rod 306, the third tube 301 can be driven to rotate when the first slider 303 slides.

[0030] In this embodiment, the first pull wire 307 section between the first intersection and the first through hole 304 is the first pull wire 307 pulling section. A sector-shaped block may be fixedly installed on the inner wall of the second tube 201, and the first pull wire 307 pulling section is located between the inner wall of the sector-shaped block and the inner wall of the second tube 201. By setting the fan-shaped block, the pulling section of the first pull wire 307 can be continuously blocked by the fan-shaped block, avoiding the pulling section of the first pull wire 307 being directly located in the second tube 201, thereby reducing the usable space in the second tube 201, thereby ensuring the use field of view of the second tube 201.

[0031] In this embodiment, please refer to Figures 1 to 12 The rotation assembly further includes a sliding locking module for controlling the sliding stroke of the first slider 303, the sliding locking module including a first guide groove 311, a second spring 312, a first guide slope 313, a second guide slope 314, a first locking block 315 and a plurality of second locking blocks 316; The first guide groove 311 is formed on the side wall of the first sliding block 303 , and the first guide groove 311 is connected to the first sliding groove 302 ; The first locking block 315 is slidably connected to the first guide groove 311. The sliding direction of the first locking block 315 is perpendicular to the axial direction of the second tube 201. The first locking block 315 is connected to the first guide groove 311 via a second spring 312. Here, the first locking block 315 is longer, and one end thereof close to the first guide groove 311 extends into the first guide groove 311 , and the first locking block 315 section in the first guide groove 311 is slidably connected to the first guide groove 311 ; A plurality of second locking blocks 316 are arranged in an array in the first slide groove 302 along the guide direction of the first slide groove 302, and the first locking block 315 is fixedly connected to the first slide groove 302; The first guide bevel 313 is provided on a side of the first locking block 315 close to the first intersection, and the second guide bevel 314 is provided on a side of the second locking block 316 away from the first intersection. When the first slider 303 slides forward, the second guide bevel 314 and the first guide bevel 313 are in contact with each other, pushing the first locking block 315 to slide into the first guide groove 311. The side wall of the first locking block 315 away from the first intersection is the first locking surface, and the side wall of the second locking block 316 close to the first intersection is the second locking surface. When the first locking surface and the second locking surface are in contact with each other, the first locking block 315 and the second locking block 316 are locked with each other to prevent the first slider 303 from sliding backward.

[0032] When the first pull wire 307 is pulled, the first slider 303 can be driven to slide forward due to the reduction in the length of the pulling section of the first pull wire 307. When the first slider 303 slides forward, the first locking block 315 can be allowed to slide into the first guide groove 311 through the second locking block 316, so that the second locking block 316 will not prevent the first slider 303 from sliding forward. When it is necessary to stop the rotation of the third tube 301, stop pulling the first pull wire 307. At this time, the first slider 303 tends to slide backward under the drive of the second spring 312, so that the first locking surface and the second locking surface are fitted together. The first slider 303 can be kept stationary by the mutual locking of the first locking block 315 and the second locking block 316.

[0033] In this embodiment, a through groove can also be provided on the side wall of the first slide groove 302, and the through groove connects the outer wall of the second tube 201 and the first slide groove 302, and there is a gap between adjacent second locking blocks 316. When the first slider 303 needs to be reset, the ejector pin can pass through the through groove and push the first locking block 315 to slide into the first guide groove 311, so that the first locking surface and the second locking surface can be unlocked, so that the first slider 303 can slide backward.

[0034] In this embodiment, please refer to Figures 1 to 12 The vagina shaping device further includes a first rotating assembly for driving the second tube 201 to rotate, the first rotating assembly including a connecting rod 202, a second slider 203, a second slide groove 204, a third spring 205, a second pull wire 206, a third pull wire 207 and a first through tube 208; The second chute 204 is provided on the inner wall of the first tube 101 , and the guiding direction of the second chute 204 is parallel to the axis of the first tube 101 ; The second slider 203 is slidably connected to the second slide groove 204; one end of the connecting rod 202 is rotatably connected to the inner wall of the second tube 201, and the other end of the connecting rod 202 is rotatably connected to the second slider 203, and the rotation axis of the connecting rod 202 is perpendicular to the axis of the first tube 101; The third spring 205 is located in the second sliding groove 204 , one end of the third spring 205 is fixedly connected to the second slider 203 , and the other end of the third spring 205 is fixedly connected to the second sliding groove 204 ; The first through-tube 208 is located above the second slider 203 and is fixedly mounted on the top of the inner wall of the first tube 101; One end of the second pull wire 206 is fixedly connected to the second slider 203 , and the other end of the second pull wire 206 extends downwardly out of the first tube 101 ; One end of the third pull wire 207 is fixedly connected to the second slider 203 , and the other end of the third pull wire 207 extends from one end of the first through tube 208 and extends from the other end of the first through tube 208 , and the other end of the second pull wire 206 extends downwardly from the first tube 101 .

[0035] When the second tube 201 needs to be rotated away from the first tube 101 (i.e., the second tube 201 rotates upward), the third pull wire 207 is pulled downward. Under the reverse action of the first through tube 208, the second slider 203 can slide upward, thereby pushing the connecting rod 202 to rotate, and then the second tube 201 rotates upward, so that the support rod 401 is aligned with the diaphragm wound 802. When the second tube 201 needs to be rotated downward, pulling the second pull wire 206 downward can allow the second slider 203 to slide downward, thereby pushing the connecting rod 202 to rotate, and then allowing the second tube 201 to rotate downward, so as to remove the second tube 201 from the patient's vagina 801.

[0036] In this embodiment, please refer to Figures 1 to 12 The wound expansion unit further includes a second rotating assembly for driving the support rod 401 to rotate, and the second rotating assembly includes a rotating cavity 402, a second through hole 403, a fourth spring 404, a fourth pull wire 405 and a through slot 406; A rotation cavity 402 is defined in the third tube 301 .

The airbag 702 is fixedly mounted on the outer wall of the fourth tube 701. The airbag 702 is filled with liquid, which can be water. When the airbag 702 is not filled with liquid, there is a gap between the airbag 702 and the inner wall of the limiting ring 703; The limiting ring 703 can be used to set the outer diameter of the fourth tube 701 to be smaller than the inner diameter of the first tube 101, so as to avoid clamping the patient's vaginal wall when the fourth tube 701 is installed. When the airbag 702 is filled with liquid, the outer wall of the airbag 702 is stuck on the inner wall of the limiting ring 703; The filling tube 704 is fixedly installed at the bottom of the airbag 702. The filling tube 704 is a hose. One end of the filling tube 704 is connected to the airbag 702. The other end of the filling tube 704 is threadedly connected to a plug to close the filling tube 704. The distance between the bottom end surface of the first tube 101 and the top end surface of the support rod 401 is less than the length of the patient's vagina 801; After the first tube 101 , the second tube 201 , and the third tube 301 are completely inserted into the patient's vagina 801 , part of the fourth tube 701 is located outside the patient's vagina 801 .

[0043] In this embodiment, the liquid filling tube 704 can also be closed by clamping the liquid filling tube 704 with a clip.

[0044] Before inserting the first tube 101, the second tube 201, and the third tube 301 into the patient's vagina 801, the airbag 702 and the fourth tube 701 can be inserted into the limiting ring 703 first, and then the airbag 702 can be filled with liquid, so that the outer wall of the airbag 702 fits tightly with the inner wall of the limiting ring 703, thereby extending the length of the first tube 101. After the first tube 101, the second tube 201, and the third tube 301 are fully inserted into the patient's vagina 801, part of the length of the fourth tube 701 is located outside the patient's vagina 801, which can facilitate medical staff to care for the diaphragm wound 802. After the diaphragm wound 802 is cared for, the fourth tube 701 can also be removed from the first tube 101, so that the patient's vagina 801 can remain naturally closed, thereby preventing pathogens in the air from directly reaching the diaphragm wound 802 and causing infection there, and at the same time avoiding destroying the balance of the natural flora in the patient's vagina 801.
