Application of New Knotting Methods in Single-hole Laparoscopic Suturing Instructional Program on the Basis of Multidirectional Stitching Technology

The surgeon's knot-tying technique plays a crucial role in the recovery of patients after single-port laparoscopy. Knot tying is very challenging in minimally invasive surgery and is a critical skill in advanced surgery. In this study, investigators introduce a new knotting technique, compare it with the traditional knotting technique in many aspects, and also discuss its application in the teaching of single-port laparoscopic knotting.
