Abstract

An endoscopic instrument for the application of ligature binders and a ligature are described. A base body and an actuation part of a handle part are longitudinally displaceable relative to each other against an elastic force within a fixed range. Connected to the actuation part is an actuation rod at whose distal end a first ratchet heat is secured. A shaft, firmly connected to the base body, carries a second ratchet head at its distal end. With the help of the ratchet heads, which are matched to the toothed end zone of a ligature binder, a ligature can be drawn together. A ligature whose end zone has already been inserted into the endoscopic instrument prior to the operation can be brought into a closed shape with the help of a constricted zone in its binding part and of a longitudinal slot in its headpiece.
