Description

Technical Field

[0001] The invention relates to a vaginal blocking device for gynecological surgery, belonging to the technical field of medical devices. Background Art

[0002] Vaginal occlusion devices used in gynecological surgery are specialized instruments designed to protect surrounding tissues, maintain a clear surgical field, maintain intraperitoneal pressure, or prevent leakage of contents during surgical procedures. Gauze wrapped in sterile medical gloves is commonly used for vaginal packing, but this approach has limitations, can be easily misplaced, and can be difficult to remove. Therefore, more efficient vaginal occlusion devices are being designed to improve occlusion effectiveness.

[0003] For example, the patent authorization publication number CN222341311U and the announcement date 20250114 discloses a vaginal occluder for gynecological surgery, which includes a handheld part and an expansion part installed at the first end of the handheld part. The expansion part automatically expands when encountering liquid to achieve the purpose of tightly sealing the vaginal stump; the surface of the expansion part is provided with an anti-slip structure to improve stability during use.

[0004] In related technologies, vaginal occluders only have a single expansion structure to achieve vaginal occlusion. The internal vaginal structure lacks rigid fixed support, and the device is easily displaced during surgical operations, resulting in the risk of occlusion failure. Therefore, medical staff are required to hold the external structure of the vaginal occluder for auxiliary fixation. However, under the pressure of maintaining the same posture for a long time, the hands are prone to slight shaking, which will also cause the occlusion position to shift, increasing the risk of occlusion failure.

[0005] To overcome the above shortcomings, the present application provides a vaginal occlusion device for gynecological surgery, which achieves occlusion of the vaginal cavity through a vaginal occlusion structure, blocks the gas leakage path, and maintains stable abdominal cavity pressure; improves the fixation stability of the vaginal occlusion device through a support device, reduces the probability of displacement during surgery, and reduces the risk of occlusion failure.

[0040] In related technologies, some gynecological surgeries require hysterectomy. Therefore, a vaginal occluder with a single inflatable structure is used to achieve vaginal occlusion, maintain stable abdominal pressure, and prevent obstruction to surgical procedures. The occluder is held in place by its external structure to prevent displacement. However, for gynecological surgeries that do not require hysterectomy, such as those for endometriosis (endometriosis), the occluder can be secured by the cervix and vagina, reducing the likelihood of displacement and workload for medical staff.

[0041] The present application provides a vaginal occlusion device for gynecological surgery, which can seal the vaginal cavity, block the gas leakage path, maintain stable abdominal cavity pressure, and improve the fixation stability of the vaginal occlusion device, reduce the probability of its displacement during surgery, and reduce the risk of occlusion failure.

[0042] The present application embodiment provides a vaginal occlusion device for gynecological surgery, such as Figure 1 、 Figure 3 and Figure 15 As shown, the vaginal occlusion device includes an expansion member 1, an inflation and exhaust member 2 and an expansion mechanism 3. The expansion member 1 includes a cervical pressing portion 11, an expansion portion 12 and a vaginal occlusion portion 13 connected in sequence; the inflation and exhaust member 2 is connected to the vaginal occlusion portion 13, and is used to drive the cervical pressing portion 11, the expansion portion 12 and the vaginal occlusion portion 13 to expand or contract; the expansion mechanism 3 is arranged in the expansion portion 12, and is used to support the expansion portion 12.

[0043] In the embodiment of the present application, before the occlusion operation, the expansion member 1 is in a contracted state, with a relatively small volume and diameter. Supported by the expansion mechanism 3, the expansion member 1 is in a stable shape, allowing the vaginal occlusion device to enter the vagina 82 easily and smoothly, reaching the cervical os, thereby minimizing discomfort experienced by the patient during insertion. After the vaginal occlusion device enters the vagina 82, the inflation / exhaust member 2 delivers gas into the expansion member 1, causing the cervical pressing portion 11, the expansion member 12, and the vaginal occlusion portion 13 to expand. After expansion, the cervical pressing portion 11 assumes a hemispherical shape, while the expansion member 12 and the vaginal occlusion portion 13 assume a cylindrical shape.

[0044] In the embodiment of the present application, the vaginal sealing portion 13 can be tightly fitted with the vaginal wall after expansion, effectively sealing the vaginal cavity 82 and reducing the probability of gas leakage from the vaginal cavity 82. After expansion, the cervical pressing portion 11 can be in contact with and tightly fitted against the cervical opening, and the expansion portion 12 can be tightly fitted with the vaginal wall after expansion, and the expansion mechanism 3 provides rigid fixed support for the expanded expansion portion 12. The cervical pressing portion 11, the expansion portion 12, and the expansion mechanism 3 cooperate to stably fix the vaginal sealing device in the vagina 82, reducing the probability of displacement during the operation, reducing the risk of sealing failure, and controlling the fluctuation amplitude of the abdominal pressure within a very small range, so that the abdominal pressure remains stable and the surgical field of view is clear and stable, providing a reliable environment for delicate surgical operations and reducing surgical risks. Furthermore, there is no need for medical staff to continuously hold the device to maintain a stable position, which can simplify the operation steps, reduce the operation intensity, reduce the dependence on the medical staff's experience, and meet the efficiency requirements of minimally invasive surgery.

[0045] In the embodiment of the present application, the operation process of the vaginal occlusion device is simple. Medical staff only need to complete the insertion and expansion actions to achieve effective occlusion, which can reduce the dependence of the device application on operating experience, shorten the preoperative preparation time, and improve surgical efficiency.

[0046] In the embodiment of the present application, the cervical pressing portion 11, the expansion portion 12 and the vaginal blocking portion 13 can be airbags, and the inflation and exhaust member 2 can be an air pump. The airbag is soft and elastic, and can adapt to the diameter of the patient's vagina 82, so that the gas is evenly distributed in the inner cavity of the expansion member 1, further improving the blocking and fixing effect of the vaginal blocking device, reducing the probability of gas leakage, and improving the comfort of use of the vaginal blocking device. By adjusting the inflation amount of the inflation and exhaust member 2, the expansion degree of the cervical pressing portion 11, the expansion portion 12 and the vaginal blocking portion 13 can be adjusted to suit patients of different ages, body shapes and symptoms, thereby improving the applicability of the vaginal blocking device. The material of the airbag includes rubber, plastic and fabric composite film.

[0047] In the embodiment of the present application, after the operation is completed, the inflation and exhaust components 2 are used to perform an exhaust operation to reduce the volume and diameter of the vaginal occlusion device. The vaginal occlusion device can be removed as a whole by applying a pulling force from the outside, thereby avoiding any part of it remaining in the patient's body and improving the safety of the operation.

[0048] In some embodiments, as Figure 1 、 Figure 3 、 Figures 8 to 12As shown, the expansion member 1 also includes a first fixing portion 14, which is arranged between the vaginal blocking portion 13 and the expansion portion 12; the expansion mechanism 3 includes a fixed cylinder 31, a rotating cylinder 33 and a plurality of expansion components, and the fixed cylinder 31 is fixedly connected to the first fixing portion 14; the rotating cylinder 33 is arranged in the inner cavity of the fixed cylinder 31 and is rotatably connected to the fixed cylinder 31; the plurality of expansion components are evenly and spacedly arranged on the periphery of the rotating cylinder 33, and the rotation of the rotating cylinder 33 drives the plurality of expansion components to move in a direction close to or away from the central axis of the rotating cylinder 33.

[0049] In the embodiment of the present application, before the occlusion operation, multiple expansion components are distributed around the periphery of the rotating cylinder 33 and are in close contact with the outer wall of the rotating cylinder 33, in a contracted state. This reduces the size and diameter of the vaginal occlusion device, allowing it to enter the vagina 82 conveniently and smoothly. As the vaginal occlusion device enters the vagina 82 and expands the expansion portion 12 to an appropriate size, the rotating cylinder 33 is rotated, driving the multiple expansion components to move in a direction away from the central axis of the rotating cylinder 33, causing the expansion components to abut against the expansion portion 12, providing support for the expansion portion 12 while ensuring a close contact between the expansion portion 12 and the wall of the vagina 82. This reduces the probability of displacement of the vaginal occlusion device during surgery and the risk of occlusion failure. Furthermore, the medical staff no longer need to continuously hold the device in a stable position, which reduces the difficulty and intensity of the operation.

[0050] In the embodiment of the present application, the first fixing portion 14 is fixed in shape and possesses a certain degree of rigidity, providing stable support for the rotating cylinder 33. A circumferentially extending slideway is provided on the fixed cylinder 31, while a circumferentially extending slider is provided on the rotating cylinder 33. The slideway and the slider are slidably connected, achieving a snap-fit ​​and rotational connection between the rotating cylinder 33 and the fixed cylinder 31. The number of expansion components can be set according to actual needs and is not limited by this application.

[0051] In some embodiments, as Figures 8 to 11 、 Figure 14 As shown, a slide rail portion 32 is provided on the side of the fixed cylinder 31 away from the inflation / exhaust component 2, and the expansion assembly includes a support block 34, a connecting rod 35 and two hinge bars 38. The support block 34 is provided at one end of the expansion portion 12 away from the rotating cylinder 33, and extends along the circumference of the rotating cylinder 33; the connecting rod 35 is provided on the side of the support block 34 close to the rotating cylinder 33, one end is slidably connected to the support block 34, and the other end is slidably connected to the expansion block 36, and an elastic member 37 is provided between the connecting rod 35 and the inner cavity of the expansion block 36; one end of the two hinge bars 38 are hinged to the end of the expansion block 36 away from the connecting rod 35, and the other end is hinged to the rotating cylinder 33 and the slide rail portion 32 respectively.

[0052] In the embodiment of this application, Figure 14As shown, when the expansion assembly is in the initial contracted state, the two arcuate hinge bars 38 are separated from the ends connected to the rotating cylinder 33 and the slide rail portion 32, with a maximum spacing, so that the support block 34 is positioned close to the rotating cylinder 33. During the expansion process of the expansion portion 12, the rotating cylinder 33 can be synchronously driven to rotate. The rotating cylinder 33 rotates relative to the fixed cylinder 31 and the slide rail portion 32, driving the hinge bars 38 hinged thereto to rotate. The ends of the two hinge bars 38 connected to the rotating cylinder 33 and the slide rail portion 32 respectively move in a direction approaching each other, driving the ends of the hinge bars 38 connected to the expansion block 36 to move horizontally in a direction away from the central axis of the rotating cylinder 33, causing the expansion block 36 to move and closely abut the expansion portion 12, providing support for the expansion portion 12 while ensuring close contact between the expansion portion 12 and the wall of the vagina 82.

[0053] In this embodiment of the present application, when the expansion portion 12 contracts, it drives the rotating cylinder 33 to rotate in the opposite direction, causing the hinge bar 38 and the expansion block 36 to return to their original positions. The support block 34 can be fixedly connected to the expansion portion 12 or connected via an elastic member or telescopic rod. The connecting rod 35 and the support block 34 can be slidably connected via a slider or a chute, which extends along the circumference of the rotating cylinder 33. The movement of the expansion block 36 drives the connecting rod 35 to slide relative to the support block 34. The support block 34 and the connecting rod 35 provide support for the upper portion of the expansion block 36, improving the movement stability of the expansion block 36, the expansion stability of the expansion assembly, and the operational stability of the vaginal occlusion device. The sliding connection between the connecting rod 35 and the expansion block 36 and the arrangement of the elastic member 37 ensure that when the expansion portion 12 expands and changes in height, the support block 34 and the connecting rod 35 can change in sync, buffering the impact force between the support block 34 and the expansion block 36 and improving the operational stability of the support block 34 and the expansion block 36.

[0054] In some embodiments, as Figure 12 and Figure 13 As shown, the slide rail portion 32 is provided with multiple slideways 321, with first hinged seats 322 disposed between adjacent slideways 321. A second hinged seat 331 is disposed on the outer wall of the rotating cylinder 33 and extends through the slideways 321. Two hinged bars 38 are hingedly connected to the first hinged seat 322 and the second hinged seat 331 at their ends distal from the expansion block 36. The slideways 321 provide guidance and space for the movement of the second hinged seat 331 and the hinged bar 38 connected thereto. Rotation of the rotating cylinder 33 drives the second hinged seat 331 and the hinged bar 38 connected thereto to slide within the slideways 321. The provision of the first hinged seat 322 and the second hinged seat 331 improves the operational stability of the two hinged bars 38, thereby enhancing the expansion stability of the expansion assembly and the operational stability of the vaginal occlusion device.

[0055] In some embodiments, as Figure 3 、 Figure 5 and Figure 8As shown, the expansion member 1 also includes a second fixing portion 15, which is arranged between the cervical pressing portion 11 and the expansion portion 12; the vaginal occlusion device also includes a clamping mechanism 4, which includes a fixing ring 41 and a plurality of clamping components. The fixing ring 41 is arranged in the expansion portion 12 and is connected to the rotating cylinder 33 through a plurality of telescopic rods 42 that are evenly and spaced apart. The plurality of clamping components are evenly arranged around the periphery of the fixing ring 41.

[0056] In the embodiment of the present application, when the expansion portion 12 expands and changes in height, the telescopic rod 42 can synchronize its own height with that of the fixed ring 41 and other structures, thereby buffering the impact force between the fixed ring 41 and the rotating cylinder 33 and improving the operating stability of the fixed ring 41 and the rotating cylinder 33. The telescopic rod 42 can be composed of two sleeve rods. The number of clamping assemblies can be set according to actual needs and is not limited by this application.

[0057] In some embodiments, as Figure 8 As shown, the clamping assembly includes a clamping cylinder 44, a clamping rod 45, a guide cylinder 46 and a curved rod 47. The clamping cylinder 44 is arc-shaped, with one end placed in the inner cavity of the second fixing part 15 and the other end passing through the second fixing part 15 and extending to the cervical pressing part 11; one end of the clamping rod 45 is passed through the clamping cylinder 44, and the other end extends out of the clamping cylinder 44 and is connected to the clamping block 43; an airbag 461 is provided in the inner cavity of the guide cylinder 46, and part of the cylinder body is passed through the end of the clamping cylinder 44 away from the clamping block 43, and the airbag 461 is connected to the clamping rod 45; one end of the curved rod 47 is connected to the fixing ring 41, and the other end is passed through the guide cylinder 46 and connected to the airbag 461.

[0058] In this embodiment of the present application, before the occlusion operation, the clamping assembly is in its initial state. The majority of the clamping rod 45 is located within the clamping cylinder 44. The opposing clamping blocks 43 are spaced relatively wide apart, creating a significant gap between the clamping blocks 43 and the cervical pressure portion 11, ensuring that the cervical os is positioned between them. The guide cylinder 46 is hook-shaped to facilitate translation of the movement of the curved rod 47 into the movement of the clamping rod 45. The clamping blocks 43 are curved and made of a flexible material or coated with a flexible layer to enhance user comfort.

[0059] In the embodiment of the present application, the vaginal occlusion device is inserted into the vagina 82, and the rotating cylinder 33 rotates, driving the expansion assembly to expand the expansion portion 12. Simultaneously, the telescopic rod 42 drives the fixed ring 41 to rotate synchronously. The fixed ring 41 drives the curved rod 47 to move in a direction approaching the guide cylinder 46, squeezing the airbag 461 within the guide cylinder 46. The gas within the airbag 461 moves toward the other end of the guide cylinder 46 to squeeze the clamping rod 45, driving the clamping rod 45 upward and causing a portion of the clamping rod 45 to extend out of the clamping cylinder 44. The clamping rod 45 is also arc-shaped. The upward movement of the clamping rod 45 drives the clamping block 43 to move in a direction approaching the central axis of the cervical pressing portion 11, cooperating with the expanded cervical pressing portion 11 to clamp the cervical os, further improving the fixation stability of the vaginal occlusion device during surgery, reducing the probability of displacement during surgery, and minimizing the risk of occlusion failure.

[0060] In the embodiment of the present application, when the operation is completed and the vaginal occlusion device needs to be removed, the rotating cylinder 33 rotates in the opposite direction, driving the expansion component to return to its original position while simultaneously driving the clamping component to return to its original position and return to its initial state to facilitate the removal of the vaginal occlusion device.

[0061] In some embodiments, as Figures 1 to 5 As shown, the vaginal occlusion device also includes a restraining tube 5, which is arranged around the periphery of the expansion part 12, and is fixedly connected to the expansion part 12 at one end close to the vaginal occlusion part 13, and a plurality of first through holes 51 are evenly and spaced apart on the tube wall; a plurality of protrusions corresponding to the positions of the first through holes 51 are provided on the outer side surface of the expansion part 12, and a flexible interlayer 52 is provided between the expansion part 12 and the restraining tube 5.

[0062] In the embodiment of the present application, the restraining tube 5 is made of elastic material, or has a stacked folding structure, similar to a zigzag, or has a pleated structure, which can produce corresponding volume changes as the expansion of the expansion portion 12. The flexible interlayer 52 includes gauze and cotton. After the expansion portion 12 expands, the multiple protrusions squeeze the flexible interlayer 52, so that part of the structure of the flexible interlayer 52 passes through the first through hole 51 and abuts against the inner wall of the vagina 82. Due to the high surface roughness of the flexible interlayer 52, the friction between the vaginal occlusion device and the vagina 82 can be increased, further reducing the probability of the vaginal occlusion device shifting with the operation during the operation, reducing the risk of occlusion failure. During the process of inserting and removing the vaginal occlusion device, the restraining tube 5 can protect the flexible interlayer 52, avoid contact between the flexible interlayer 52 and the wall of the vagina 82, facilitate the insertion and removal of the vaginal occlusion device, and prevent the flexible interlayer 52 from being sutured or retained by mistake, thereby improving the safety of the operation.

[0063] In the embodiment of the present application, the restraining tube 5 is actually a tubular structure with a relatively small thickness. The larger thickness is only shown in the accompanying drawings for clarity. To increase the contact area between the flexible interlayer and the inner wall of the vagina and improve friction, the size of the first through hole 51 can be correspondingly enlarged. The first through hole 51 can be a square hole, a round hole, or a polygonal hole. The shape and size can be set according to actual needs, and symmetry is not limited in this application. The structures that directly contact the skin of the patient's vagina 82, such as the expansion portion, the restraining tube 5, and the clamping block 43, can be made of medical-grade materials such as silicone, polyethylene, polytetrafluoroethylene, etc., which have good biocompatibility, flexibility, and stability to avoid irritation or damage to the vaginal mucosa 82.

[0064] In some embodiments, as Figure 1 、 Figure 3 and Figure 5 As shown, the inflation member 2 includes an inflation cylinder 21, an inflation plug 22, and an inflation rod 23. The inflation cylinder 21 is in communication with the vaginal sealing portion 13, the inflation plug 22 is disposed within the inner cavity of the inflation cylinder 21, and the inflation rod 23 is partially disposed within the inflation cylinder 21 and connected to the inflation plug 22. The expansion or contraction of the expansion member 1 is controlled by controlling the pushing direction of the inflation rod 23, and the degree of expansion of the expansion member 1 is controlled by controlling the pushing depth of the inflation rod 23.

[0065] In some embodiments, as Figures 5 to 7 As shown, the vaginal occlusion device further includes a drive assembly 6, which includes a spiral groove 61 and a movable rod 62. The spiral groove 61 is provided on the inner wall of the rotating cylinder 33. One end of the movable rod 62 passes through the inflation rod 23 and the inflation plug 22 and is placed inside the inflation cylinder 21. It is slidably connected to the spiral groove 61 via a slide rod 621, and the other end is placed outside the inflation rod 23. Manually pushing the end of the movable rod 62 outside the inflation rod 23 causes the movable rod 62 to extend further into the inflation cylinder 21. The movable rod 62 drives the slide rod 621 upward, and the slide rod 621 provides an upward force to the rotating cylinder 33. At this time, the rotating cylinder 33 is also subjected to the force provided by the fixed cylinder 31. Under the action of these forces, the slide rod 621 drives the rotating cylinder 33 to rotate, gradually moving from the low position to the high position along the spiral groove 61, thereby achieving the change in the working state of the expansion assembly and the clamping assembly.

[0066] In this embodiment, the downward movement of the movable rod 62 drives the rotating cylinder 33 to rotate in the opposite direction. By controlling the distance of the movable rod 62's movement, the rotation angle of the rotating cylinder 33 can be controlled, thereby controlling the movement of the expansion and clamping assemblies. A sealing ring is provided between the movable rod 62 and the inflation rod 23 or inflation plug 22 to ensure the tightness of the inflation cylinder 21 and the operational stability of the inflation and exhaust device 2.

[0067] In some embodiments, as Figures 5 to 7As shown, the vaginal occlusion device also includes a limiting component 7, which includes an extension portion 71, an air injection cylinder 72, a locking cylinder 73 and an air delivery pipe 74. The extension portion 71 is arranged between the vaginal occlusion portion 13 and the air injection cylinder 21. Along its own extension direction, the inner cavity of the extension portion 71 is evenly provided with a plurality of limiting teeth 711; the air injection cylinder 72 is arranged on the side of the moving rod 62 away from the rotating cylinder 33, and the inner cavity is provided with an air injection plug 721, and the air injection rod 722 is passed through the air injection cylinder. 72 is connected to the gas injection plug 721; the locking cylinder 73 is arranged in the placement cavity 622 of the movable rod 62, and the inner cavity is provided with a locking plug 731, the locking plug 731 is connected to the locking tooth 733 through the locking rod 732, and the locking tooth 733 is used to engage with the limiting tooth 711; the air supply pipe 74 is arranged in the placement cavity 622, one end is connected to the gas injection cylinder 72, and the other end is connected to the locking cylinder 73, and the locking plug 731 is located between the air supply pipe 74 and the locking rod 732.

[0068] In the embodiment of the present application, pressure is manually applied to the external gas injection rod 722, and the gas injection rod 722 pushes the gas injection plug 721 to move, so that the gas in the gas injection cylinder 72 is transmitted to the locking cylinder 73 through the gas pipe 74, and the gas pushes the locking plug 731 in the locking cylinder 73 to move to the right, and the locking plug 731 drives the locking rod 732 and the locking tooth 733 to move to the right and extend out of the placement cavity 622, so that the locking tooth 733 is engaged with the limiting tooth 711 to limit the movement of the movable rod 62, so that the position of the movable rod 62 is fixed, thereby limiting the rotation of the rotating cylinder 33, so that the expansion assembly and the clamping assembly maintain the current working state, improve the working stability of the expansion assembly and the clamping assembly, and improve the working stability of the vaginal occlusion device.

[0069] In this embodiment of the present application, the placement chamber 622 is in an inverted L-shape, with two openings: one for mounting the gas injection cylinder 72 and the other for providing space for the engaging teeth 733 to move. The gas delivery tube 74 extends parallel to the direction of extension of the gas injection cylinder 72 and perpendicular to the direction of extension of the engaging cylinder 73. Before driving the movable rod 62 up and down, the gas injection rod 722 can be manually withdrawn to one end, allowing the gas pressure to retract the engaging teeth 733, positioning them within the placement chamber 622 and preventing them from interfering with the stop teeth 711 and affecting the movement of the movable rod 62.
