A grasping instrument provided with a guided-on, attachable, modified knot pusher and designed for positioning and fixing a knot in a suture at a remote surgical location. The knot is easily formed outside the patient's abdominal cavity by hand and fixed on the instrument tip. After intra-abdominal insertion, the knot pusher serves to forward the knot on the thread and to immediately tighten it without any troublesome instrument change being required. A spring-loaded mechanism enables the applied force to be predetermined for achieving a reliable knot strength.
