A cutting device for a surgical instrument, especially for a laparoscopic instrument, for the cutting of binding element, such as ligature binders, surgical suture material, etc. or of other objects is described, the end-piece which is to be out off of the object being drawn in by the instrument until a thicker section of the object, such as the headpiece of a ligature binder or a knot in surgical suture materials, etc., reaches the vicinity of the instrument head. The cutting device has a cutting part arranged at the instrument head, the cutting edge of the cutting part being moved essentially transversely through the end-piece by an actuation part engaging at the thicker section upon the continued drawing-in of the end-piece which is severed when a pre-set force is exceeded.
