Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a vaginal plug after total hysterectomy. Background Art

[0002] In the existing laparoscopic total hysterectomy, carbon dioxide gas is continuously injected into the patient's abdominal cavity before the operation. Carbon dioxide is used as the inflation medium for laparoscopic surgery to expose the abdominal organs, providing a surgical field of view and an easily operable surgical environment. However, after the removed uterus is taken out from the vagina, the carbon dioxide gas in the abdominal cavity will overflow to the outside through the vagina, showing the phenomenon of "air leakage". This will lead to insufficient abdominal cavity dilation, making it difficult to perform subsequent surgical operation steps. Therefore, it is necessary to block the vagina to avoid the leakage of carbon dioxide gas.

[0003] Most of the existing blocking methods use sterile latex gloves and sterile gauze to make a spherical rubber ball, and then use the rubber ball to block the vagina. However, the shape of the rubber ball is not standard and may not be suitable for different patients. Moreover, after the rubber ball is put in, the rubber ball may slide and cannot be fixed, resulting in poor stability and easy air leakage. Summary of the Invention

[0004] The present invention aims to provide a vaginal plug after total hysterectomy to solve the problems of poor sealing and poor stability when blocking the vagina in the prior art.

[0005] To achieve the above object, the present invention provides the following technical solution:

[0006] A vaginal plug after total hysterectomy includes a main sleeve. An annular airbag is sleeved outside the main sleeve. The main sleeve is integrally formed with a plurality of rotating plates. The rotating plates are rotatably connected to the main sleeve. A first sliding rod is connected inside the main sleeve. A driven block is slidably connected to the first sliding rod. A linkage rod is rotatably connected to the driven block. One end of the linkage rod is rotatably connected to the driven block, and the other end is rotatably connected to the rotating plate. The number of linkage rods corresponds to the number of rotating plates. The first sliding rod is connected with a main body rod. One end of the main body rod is connected to the first sliding rod, and the other end is connected with a second sliding rod. The second sliding rod is connected with a limiting block. A half-thread is provided on the second sliding rod. A control block is slidably connected to the second sliding rod. The control block and the driven block are connected by a connecting rod. The connecting rod penetrates through the main body rod. The control block and the limiting block are connected by a spring. A locking bolt is threadedly connected to the half-thread. The locking bolt is used to limit and lock the control block. The annular airbag is connected with a communicating pipe. The communicating pipe is connected to the main body rod. The communicating pipe is used to fill gas or liquid to inflate the annular airbag.

[0007] Further, four rotating plates are provided, and the four rotating plates are arranged in an equidistant circular array.

[0008] Further, a buckle is connected to the main rod, and the buckle is used to snap into the connecting pipe.

[0009] Further, the annular airbag is bonded to the outer side of the main sleeve.

[0010] Further, the connecting rods are arranged in two, and the two connecting rods are symmetrically arranged.

[0011] Principle and beneficial effects of the technical solution: In the device of the present invention, an annular airbag is sleeved on the main sleeve. By inserting the main sleeve into the vagina, and then inflating or introducing liquid into the annular airbag through the connecting pipe, the annular airbag expands, so that the annular airbag tightly adheres to the inner wall of the vagina, blocking the vagina; at the same time, after the annular airbag expands, gently pull the control block backward, so that the rotating plate rotates outward and unfolds, so that the tail end of the annular airbag expands, and the rotating plate applies a certain pressure to the tail end of the annular airbag, which can better make the annular airbag fit the inner wall of the vagina, and can also better improve the stability of the device, ensuring that the device can firmly block the vagina; after the control block is pulled backward by a certain distance, it is locked by the locking bolt. Rotate the locking bolt until the locking bolt abuts against the control block, so that the control block cannot return to the initial position under the action of the spring, thus locking the control block.

Detailed Embodiments

[0018] The present invention will be further described in detail below with reference to the drawings and embodiments:

[0019] As Figures 1-5A vaginal plug after total hysterectomy is shown, including a main sleeve 1. An annular airbag 2 is adhesively connected to the outside of the main sleeve 1. Four rotating plates 11 are arranged in an equidistant array on the main sleeve 1. The four rotating plates 11 are integrally formed with the main sleeve 1 and are rotatably connected to the main sleeve 1. A first sliding rod 12 is connected inside the main sleeve 1. A driven block 13 is slidably connected to the first sliding rod 12. Four connecting rods 14 are rotatably connected to the driven block 13. The positions of the four connecting rods 14 correspond to the positions of the four rotating plates 11. One end of the connecting rod 14 is rotatably connected to the driven block 13, and the other end is rotatably connected to the rotating plate 11. The right end of the first sliding rod 12 is connected to a main body rod 3. The right end of the main body rod 3 is connected to a second sliding rod 4. A limiting block 41 is connected to the right end of the second sliding rod 4. A semi-thread 42 is provided on the second sliding rod 4. A control block 5 is slidably connected to the second sliding rod 4. The control block 5 and the limiting block 41 are connected by a spring. The spring is sleeved on the second sliding rod 4. A locking bolt 7 is threadedly connected to the semi-thread 42. Two connecting rods 6 are connected to the left end of the control rod. The two connecting rods 6 are arranged symmetrically up and down. The left ends of the two connecting rods 6 are connected to the right end of the driven block 13. The driven block 13 and the control block 5 are connected by the connecting rod 6. A communicating pipe 21 is connected to the right end of the annular airbag 2. Two buckles 31 are provided on the main body rod 3. The communicating pipe 21 is clamped on the buckles 31. The tail end of the communicating pipe 21 is located at the position of the first sliding rod 12.

[0020] The specific implementation process is as follows: After removing the uterus from the vagina and blocking the vagina, first hold the main body rod 3 and insert the main sleeve 1 into the vagina. Then, inject gas into the annular airbag 2 through the tail end of the communicating pipe 21 with a syringe or other inflation device, so that the annular airbag 2 expands, and thus the annular airbag 2 fits with the vagina. After the annular cavity is inflated, the control block 5 can be gently pulled backward. The control block 5 moves to the right, driving the driven block 13 to move to the right. The driven block 13 moves to the right, driving the connecting rod 14 to rotate. The connecting rod 14 rotates, driving the rotating plate 11 to rotate outward, so that the right end of the rotating plate 11 lifts the tail end of the annular airbag 2, expanding the tail end of the annular airbag 2, which can apply pressure to the annular airbag 2, further improving the sealing performance and the stability of the device. Then, rotate the locking bolt 7 so that the locking bolt 7 abuts against the control block 5, and the control block 5 cannot return to the initial position, thus locking the entire device and completing the blocking of the vagina.
