A simple technique of using novel thread-holding and knot-pushing forceps for extracorporeal knot-tying

We designed some novel knot-pushing forceps for extracorporeal knot-tying and describe herein our simple technique of utilizing them. These forceps are modified only by a single 1-mm hole between their jaws, which hold a thread and push the knot toward the ligating tissue. The application of this simple device was handled well by surgeons beginning to perform advanced endoscopic surgery. The simple modification explained in this report seems applicable to most of the forceps currently used.
