Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and particularly relates to an adjustable device for assisting the return of the amniotic sac during emergency cervical cerclage surgery. Background Art

[0002] During emergency cervical cerclage, amniotic sac prolapse or bulging due to cervical insufficiency or other factors not only increases the difficulty and risk of the operation, but may also pose a threat to the life safety of the fetus and pregnant woman. Traditional reduction methods often rely on the doctor's experience and feel, and have problems such as complex operation and unstable reduction effect. Therefore, there is an urgent need for a device that can assist doctors in performing accurate and efficient amniotic sac reduction in clinical practice.

[0003] Chinese patent publication number CN219558426U describes a balloon for inserting the amniotic sac during emergency cervical cerclage surgery. The balloon comprises a hollow catheter, one end of which is connected to a balloon seat, the other end of which is connected to a one-way valve, and a balloon body connected to the balloon seat. The top of the balloon seat is fixedly connected to the inner wall of the balloon body, and the side of the balloon seat is sealed to the edge of the balloon body. A through hole is provided in the balloon seat for connecting the catheter and the internal space of the balloon body. The present invention allows for the injection of saline or air into the balloon body via the one-way valve through the catheter and the through hole, causing the balloon body to expand. When the balloon body expands, a concave structure is formed on the balloon body at the position corresponding to the top of the balloon seat. This prevents damage to the amniotic sac during inserting the amniotic sac, thereby improving the success rate of the surgery.

[0004] However, the above technical solution can inject physiological saline or air into the balloon body through the one-way valve, the catheter and the through hole to expand the balloon body, and will not damage the amniotic sac when returning the amniotic sac. Although this device can be easily pushed into the amniotic sac, the above device is an integrated design. During use, if a part of it is damaged, the entire device needs to be replaced, resulting in a relatively general use effect of the device, so staff need to improve it. Utility Model Content
