The invention of this invention is pushing the swollen membranes to the exterior of the first cervical suture when the cervix This mechanism relates to an air injection tube 130 which air is injected by the action of an air injection means 120 is configured on one end portion Inflatable balloon 160 and pushing the other end into the uterine cavity is formed directly protruding membranes are inflated by the air injected through the air injection tube 130 of the air injection tube (130), the inflatable balloon 160 except for a portion is formed consisting of the air injection tube 130 is inserted into the one-piece outer cylinder 140 and the outer tube 140, and inflation balloon 160 is coupled between the support (150) characterized in that: it consists of the whole part of the rear stably supported state by an expansion balloon 160, the arm 150 is configured to forward the When applying the present invention the air inlet tube (130) The expansion in the course of pushing the swollen membranes balloon 160 is in an expanded state form modified or not pushed to the rear of the cervix is facilitated this repair procedure, as well as the outer tube 140 and the air inlet tube 130 has a one-piece is composed of an operator is able to individually manipulate insertion tool with one hand, the amniotic membrane in a state caught give 100 as a whole and the other with one hand has the advantage that maximize the efficiency of the cervical sutures to be stitched neck surgery. In addition, the present invention is to form a stable support by the inflatable balloon 160 is configured as a thick material that consists of a flexible material and has a front concave portion 166 forms a rear support is 150 moderate degree of inflation of the inflatable balloon 160, according to some pulled out amniocentesis ( ) also performed without projecting a positive amount of amniotic membrane in the amount of the youngest case of treatment the patients membranes consist been a lot of projection
