By arranging the isolation bag 5 made of flexible materials, the isolation bag can be contracted into a smaller volume during operation and is sent into an abdominal cavity by a laparoscope, the operation forceps pull the pull ring 7 to open the bag opening 51 to wrap the uterus 8 to be cut, the bag opening 51 is tightened and sleeved at the joint of the cervix 81 and the uterine body 82 of the uterus 8, before the separation from the vaginal wall, the operation forceps pull the pull ring 7 to open the bag opening 51 to be sleeved outside the vaginal wall on the anti-skid part 13 of the fornix cup 1, under the combined action of the bag opening 51 and the anti-skid part 13, the isolation bag 5 wraps the uterus 8 and the separated vaginal wall, then the support rod 2 is pulled and the isolation bag 5 is pushed to convey tissues cut by the operation to the outside of a human body through the vagina, the whole process realizes the sterile and tumor-free principle of the operation, and has high safety; the air bag 3 is arranged on the support rod 2, so that the air can be inflated in the operation process to ensure the sealing of the vagina, and the operation can be normally carried out; the vault cup 1 made of silica gel is arranged to be a hollow structure at the front end and a solid structure at the rear end, so that the vault cup 1 has enough supporting force, and meanwhile, the vault cup 1 made of silica gel has small irritation to the cervix 81 when being sleeved on the cervix 81.

During operation, the supporting rod 2 pushes the fornix cup 1 to pass through the vaginal wall to the cervix 81 of the uterus 8, before the vaginal wall is not broken, the vaginal wall is tightly clamped outside the fornix cup 1 and is positioned between the anti-slip part 13 and the bag opening 51 of the isolation bag 5 to seal the vaginal wall and prevent the fallen cancer cells and the like from overflowing, and because the size of the bag opening 51 is smaller than the cross-sectional size of the fornix cup 1, the bag opening 51 can be tightly tightened on the fornix cup 1, so that the whole uterus 8 and the broken vaginal wall are positioned in the isolation bag 5 for isolation.

In one embodiment, the womb lifting device further comprises a binding belt 6, one end of the binding belt 6 is fixedly connected with the bag opening 51, the other end of the binding belt is arranged in a suspended mode, and the pull ring 7 is arranged on the binding belt 6. Through setting up bandage 6, can bind sack 51, further prevent that the sack 51 of isolation bag 5 from breaking away from fornix cup 1, set up pull ring 7 on bandage 6 moreover, the operation pincers pulling pull ring 7 of being convenient for reduces the operation degree of difficulty.

In one embodiment, the isolation bag 5 is a silicone bag. Through setting up isolation bag 5 into the silica gel bag, the silica gel bag has elasticity, can grow or reduce as required to satisfy the parcel and the isolation of the uterus 8 of different sizes, the commonality is strong, and isolation bag 5 that silica gel made can also reduce to very little volume, is convenient for send into to the abdominal cavity from peritoneoscope department.

In this embodiment, the outer surface of the isolation bag 5 is provided with an adsorption layer 9. By arranging the adsorption layer 9, after the isolating bag 5 is sleeved with the separated uterus 8 and the vaginal wall, when the supporting rod 2 pulls the isolating bag 5 to pass through the vagina, the adsorption layer 9 further cleans the wound surface of the pelvic floor and the vagina.

Specifically, the adsorption layer 9 is a sponge layer or a silica gel layer with holes. The sponge layer and the silica gel layer with holes have good adsorption effect on tissues and blood, and do not damage the vaginal wall.

Further, a wavy structure is arranged on one side surface, away from the isolation bag 5, of the adsorption layer 9. The wavy texture structure can enhance the cleaning effect of the adsorption layer 9.

In this embodiment, the absorbent layer 9 is fixed on the outer surface of the isolation bag 5 by means of glue. Of course, in other embodiments, ultrasonic welding may be adopted to fix the isolation bag 5, or the absorption layer 9 and the isolation bag 5 are directly integrally formed, for example, when the absorption layer 9 is a silica gel layer, and the isolation bag 5 is a silica gel bag, the isolation bag 5 and the absorption layer 9 made of the same material may be integrally formed.

In one embodiment, a handle 21 is provided at the end of the support rod 2 away from the vault cup 1. By arranging the handle 21, the uterus lifting device is convenient to operate in operation, and the operation difficulty is reduced.

In one embodiment, the inflation tube 4 is disposed outside the support rod 2. In other embodiments, the inflation tube 4 may also be hidden in the support rod 2, specifically, a through hole is formed in the support rod 2 along the length direction thereof, and the inflation tube 4 passes through the through hole and is communicated with the airbag 3.

In one embodiment, the anti-slip portion 13 is a bump structure disposed on the outer surface of the dome cup 1. The bump structure can form unevenness on the outer surface of the vault cup 1, so that the friction force at the position is increased, and the bag mouth 51 of the isolation bag 5 is prevented from falling off.

The uterine lifting device of the utility model has simple structure, can effectively prevent uterus 8 from dropping or the dropping tumor cells from overflowing when the uterine tissue is disturbed and stimulated and the vaginal wall is broken during the operation, and further cleans the pelvic floor surface and the vagina through the adsorption effect of the flexible adsorption layer 9 of the isolation bag 5 sleeved outside the uterus 8; but also ensures that the operation convenience of cutting the uterus 8 is realized by the pulling action of the pull ring 7 at the bag opening 51 of the isolation bag 5 sleeved outside the uterus 8 when the central guide rod has no function of supporting the uterus body 82; in addition, the constant air pressure in the abdominal cavity is ensured in the operation. Therefore, the uterus lifting device can ensure the sterile and tumor-free operation of the excision of the uterus 8 under the laparoscope and improve the reliability and the safety of the operation.
