Description

Saccule for receiving amniotic sac in emergency cervical ring ligation

Technical Field

The utility model relates to the technical field of medical auxiliary equipment, in particular to a balloon which is used for accommodating an amniotic sac in an emergency cervical ring ligation operation.

Background

Cervical insufficiency, also called cervical internal locking insufficiency, cervical relaxation, is mainly caused by congenital dysplasia of the cervix or acquired traumatic functional defects, accounting for 0.5% -1% of all pregnant women. The clinical characteristics of cervical insufficiency are that the painless cervical dilation during pregnancy causes the expansion of amniotic sac (the amniotic sac refers to the pregnant sac which grows up after pregnant women become pregnant, gong Qiangna contains fetal heart, fetal buds and weak alkaline amniotic fluid, and the temperature is relatively constant), and finally late abortion or premature delivery are easily caused.

Cervical cerclage is a preventive intervention for the loss of a fetus in premature birth and mid-gestation due to cervical insufficiency, which refers to the annular suture of the endocervical orifice with a wire to tighten the cervix. Cervical cerclage can be classified into preventive cervical cerclage and acute cervical cerclage according to the operation time. Emergency cervical ligation refers to an emergency procedure in which the cervix has been dilated and the embryo sac is exposed to the external cervical orifice.

In the process of realizing the technical scheme, the inventor finds that at least the following problems exist in the prior art:

in the urgent cervical ring ligation, the operator needs to stitch more tissues as much as possible and cling to the internal cervical orifice as much as possible to obtain a supporting force, as the cervical canal is shortened due to the change of the cervix, the amniotic sac is inflated, the stitching height is difficult to reach a satisfactory degree, and the amniotic sac is easy to damage during stitching to cause rupture of the fetal membrane, thereby causing unavoidable bad fatigues such as abortion and premature delivery. If the head and hip height of the patient is adopted in the operation, the removed amniotic sac is pushed back to the uterine cavity through cervical by using oval forceps to clamp gauze and other modes (still refer to that a doctor enables the patient to be removed or the dislocated tissue or the trunk to restore to the original position through the manipulation), the amniotic sac is easily damaged due to uneven stress, and the effect is poor.
