An instrument for use in uterine laparoscopic surgery, said instrument including a tubular element which is adapted for insertion into the vagina with the front end-part of the instrument, as seen in the insertion direction, receiving the cervix, wherewith the edge of the front part of said tubular element is shaped to support against the top wall of the vagina, and wherewith the instrument includes a sealing ring which embraces the tubular element and functions to provide a seal between said element and said vaginal wall. The edge portion of the front part of the tubular element is constructed so that the top wall of the vagina will be supported around the full periphery of said edge portion when the tubular element is positioned in the vagina. The instrument includes end closure means detachably fastened to the tubular element and the rear end-part of the tubular element is adapted to provide an anchorage for a suture which is anchored through the cervix. The rear end of the tubular element, as seen in the insertion direction, carries the end closure means which functions to pressure-seal the passageway passing through said tubular element. |
