Abstract

The invention relates to an automatic pressure control self-release balloon dilatation uterus stent which comprises a stent body, a pressure control device and a conveyor, the stent body comprises a balloon and a water filling catheter connected with the balloon, the pressure control device comprises a water injection cylinder, a water injection catheter and a pusher, a piston and a push rod are arranged in the water injection cylinder, the push rod is connected with the pusher, and the conveyor is connected with the piston. A one-way sealing valve and a check valve are arranged in the water filling conduit, one end of the water filling conduit is connected with the water filling cylinder, the other end of the water filling conduit is inserted into the water filling conduit, the conveyor comprises a sleeve, a tail cover clamped with the sleeve and an operating rod, and a push disc is arranged at the top end of the operating rod. The balloon can be slowly released while the uterine stent is placed, the pressure provided by the pusher is used for injecting water into the balloon, the pressure of the pusher is basically constant, the situation that too much water is injected into the balloon to excessively expand and press the uterus can be prevented, and the risk of endometrial necrosis is reduced. Meanwhile, the balloon dilatation uterine stent is easy to use, the difficulty of placing the balloon dilatation uterine stent can be remarkably reduced, and the comfort level of a patient is high.

Description

Technical field: [0001] The invention relates to the technical field of medical devices, in particular to an automatic pressure-controlled self-releasing balloon-expandable uterine stent. Background technique: [0002] Intrauterine adhesions are mainly caused by endometrial basal layer damage and scar formation caused by curettage and infection. The incidence of adhesions is 30-40%. In addition, unexplained intrauterine adhesions often appear clinically. Intrauterine adhesions can cause decreased menstrual flow, amenorrhea, and infertility, seriously affecting the health of the reproductive system of patients, and destroying the harmony and stability of the family and society. At present, there are many ways to prevent intrauterine adhesions at home and abroad, including drug therapy represented by estrogen drugs, mechanical barrier isolation, etc. Among them, the balloon-expandable stent is a commonly used mechanical barrier isolation method in clinical practice, with def...
