Description

Portable adjustable cervical cerclage amniotic sac lifting device

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to a cervical cerclage amniotic sac lifting device with adjustable it is portable.

Background

In medical practice, cerclage is an operation of circularly suturing the cervix with a special suture to prevent late abortion and premature delivery due to cervical insufficiency. Cervical insufficiency is currently not defined uniformly, but is often characterized by cervical shortening and dilation in the absence of signs of preterm birth prior to 37 weeks of gestation. The typical clinical manifestations are painless, progressive cervical canal dilatation in the middle of pregnancy with or without amniotic sac protruding the cervical orifice, eventually leading to mid-term pregnancy abortion and premature delivery. The emergency cervical cerclage is to suture the dilated cervix, thereby extending the pregnancy. However, in the emergency cerclage, the cervical orifice is usually expanded, the amniotic sac protrudes out of the cervical orifice and even into the vagina, the visual field of the vagina is narrow, and the cervical orifice is difficult to expose, thereby bringing difficulty to the operation. In addition, in the case of sewing, the sewing needle is difficult to avoid touching the amniotic sac, which finally causes rupture of the fetal membrane and failure of the operation.

At present, the following methods are commonly adopted clinically: 1. pushing the amniotic sac into the uterine cavity by using a balloon (Foley catheter or water sac promoting cervical ripening) injected with saline; however, when the amniotic sac is obviously protruded, the Foley catheter is easy to bend and is difficult to operate by the Foley catheter; the water sac promoting cervical ripening is in an ellipsoid shape, the shape can not completely wrap the protruded amniotic sac, the stress on the top end of the water sac is concentrated, the amniotic sac is easily pressed, and the probability of rupture of the amniotic sac is increased. 2. The amniotic sac is covered by sterile gauze or pushed lightly by applying force, the method is easy to implement, amniotic fluid is in the amniotic sac and has fluidity, the amniotic sac is often not easy to push into a uterine cavity by being covered by the gauze, a small amount of tissue may be left in a vagina, the amniotic sac is thin, and the amniotic fluid flows out once the amniotic membrane is injured during operation, so that the cerclage operation fails.

The prior art discloses a related device for assisting the operation of a traditional gauze pad mode, and the device mainly focuses on the application of an air bag and a water bag except for a basic fixing instrument, but practice shows that the device does not have the corresponding technology for further adjustment by only using the fixing instrument, and on the other hand, a force bearing structure is unstable by using the air bag and the water bag, so that the direction can not be accurately fixed in the lifting process easily, and the risk of rupture caused by unidirectional extrusion is caused.
