Description
Technical Field
The utility model relates to a medical instrument, in particular to an automatic vagina retractor for cervical cerclage.
Background
Late abortion and premature birth caused by cervical insufficiency are important reasons for fetal death and serious sequelae, and cervical cerclage is the only positive effective means for treating cervical insufficiency at present. Transvaginal cervical cerclage surgery is itself relatively simple, but the greatest difficulty in surgery is-difficulty in exposing the surgical field. Because the vagina is a naturally closed organ, an assistant needs to draw a hook in order to expose the operation visual field, the position where the assistant stands basically cannot see the operation of a main surgeon, the main surgeon needs to constantly command the adjustment of the hook position, and two hands of the assistant can only draw in two directions, so that the operation visual field is often difficult to completely expose and satisfy. Especially, when the cervix is subjected to urgent cerclage, the cervix is flattened, the uterine opening is opened, the amniotic sac protrudes out of the cervix, the Mersilene cerclage is wider, the needle is large, and the operation is more difficult in a narrow space of the vagina although an assistant retractor is provided, so that the operation time is prolonged, and the operation effect is reduced to a certain extent. Simultaneously in urgent cervical cerclage, the operation doctor often needs the two-chamber ureter to beat the amniotic sac and push up the amniotic sac in order to avoid the seam needle to puncture the amniotic sac, but, because the two-chamber ureter is soft, and amniotic sac tension is great, does not fix well after pushing up the amniotic sac, and the slippage is very easy, not only lets the doctor in operation in a busy or disorderly hand and foot, has reduced the possibility of operation success, has still increased the cracked risk of fetal amniotic sac, leads to miscarriage and early childbirth unavoidable.
SUMMERY OF THE UTILITY MODEL
