Abstract
A device for operating the coeliac tubular member-closing implement comprises an outer tube, a hollow cylindrical needle which is inserted into the outer tube and whose forward end portion contains the coeliac tubular member-closing implement, a push tube for forcing the coeliac tubular member-closing implement out of the needle, a drive tube which is inserted into the push tube to move a second stop toward a first stop, and an elongated holding member which is inserted into the drive tube to hold the coeliac tubular member-closing element at the prescribed position. The needle is let to penetrate the coeliac tubular member which is going to be closed, with the coeliac tubular member-closing implement received in the needle. Thereafter, the needle is pulled out by the push tube with the coeliac tubular member-closing implement still retained in the coeliac tubular member. The second stop is pushed by the drive tube, thereby closing the coeliac tubular member by the action of both first and second stops.
