Scissor-Knot-Pusher: An Instrument for Simplified Laparoscopic Extracorporeal Knotting

摘要

This paper describes the “scissor-knot-pusher,” an instrument that greatly facilitates the execution of knot tying during laparoscopic operations. The instrument acts in essence as an extension of the surgeon's hand and, given its rigid structure, allows the surgeon full control of the process of knot tying. Additionally, after the knot has been tightened, it is possible to cut the suture without using a different instrument. As a result, this technical device simplifies knot tying and may help to reduce the frustration and the time often associated with intracorporeal suturing during laparoscopic surgery.
