Description

Fetal sac resetting structure for emergent cervical cerclage operation of fetal sac protruding into vagina

Technical Field

The utility model belongs to the technical field of medical instrument, concretely relates to fetal sac reduction structure for when being used for the emergent cervical cerclage art in the protruding vagina of fetal sac.

Background

The cervical canal is characterized by a loose inner opening, also called cervical insufficiency, which means the state of the cervical canal with loose and weak tension. The relaxation of the internal opening of the cervical canal is one of the causes of habitual abortion and premature birth in the middle of pregnancy. When the internal opening of the cervical canal is relaxed, the function of the isthmus sphincter is reduced, so that the internal opening of the cervix is expanded in a pathological way. After the midgestation period, the fetal sac can protrude outwards from the inner opening of the cervical canal to induce uterine contraction and abortion. Generally, the symptoms are easy to relax from the 4 th to 5 th months of pregnancy, and if the symptoms occur, the symptoms are treated in time to avoid that the fetal cells fall into the vagina, so that water is broken to cause abortion.

The reasons for the relaxation of the internal os of the cervical canal can be divided into two categories: congenital and acquired. Congenital cervical canal internal orifice relaxation is caused by that the mother takes certain medicine or other reasons when pregnant to cause the female uterine hypoplasia; the acquired cervical canal internal orifice laxity is caused by birth injury, excessive uterine curettage or frequent perineal examination.

The cervical circumferential suture is an effective method for treating cervical canal internal opening looseness, namely, the cervical canal internal opening is annularly sutured by using nylon wires or 10-gauge silk threads, and the cervical canal is tightened and ligated. Is suitable for gestation period, and has simple method and easy stitches removal. Has no influence on pregnancy, does not risk cervical wound dehiscence, and does not need cesarean section during delivery.

The purpose of the surgical treatment is to repair the cervix and establish the formation and function of a normal cervical orifice, enabling pregnancy to be maintained to an advanced stage.

In the cervical encircling suture operation, a patient is ordered to have a head low and a hip high position, a simple sacculus similar to a ureter but made of softer material than the ureter is used, the sacculus is pushed upwards through the sacculus, so that the sacculus is restored to the uterine cavity as far as possible, and then cervical cerclage is performed. At present, no special tool for pushing the fetal sac up is clinically available, and a simple self-made balloon is generally adopted, so that the fetal sac is difficult to push up, the recovery effect is poor, and the operation time is prolonged.

The utility model aims at the above problem, provide a fetal sac reduction structure that is used for when emergent cervical cerclage art in the protruding vagina of fetal sac.

SUMMERY OF THE UTILITY MODEL
