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 a nd describe herein our simple technique of utilizing them. These forceps ar e modified only by a single l-mm hole between their jaws, which hold a thre ad and push the knot toward the ligating tissue. The application of this si mple device was handled well by surgeons beginning to perform advanced endo scopic surgery. The simple modification explained in this report seems appl icable to most of the forceps currently used.
