Background
For some women with cervical insufficiency, such as those with the inner opening of the cervix expanding into a funnel or U-shaped change, especially for pregnant women with amniotic sac protruding out of the cervix, the cervix needs to be cerclaged, the existing cerclage is to push back the amniotic sac by a water sac for induction of labor and then expose the cervix by a forceps. The water ejecting sac is generally formed by clamping three or four cervical clamps at three or four point positions of the cervix, the clamps are gathered together to draw the cervix together, and the needle holder is put in again to suture and close the cervix. As the cervical clamps are too many and the needle holders are added, the cervical clamps have more instruments, limited space and few operation visual angles, thus causing inconvenient operation, long operation time, more operation errors and low cerclage efficiency.
