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

Completed

• Conditions: Knotting Methods; Single-port Laparoscopic Surgery
• Interventions: Other: knotting methods

• Registration Number: NCT05762575
• Lead Sponsor: Second Affiliated Hospital of Wenzhou Medical University

Brief Summary

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.

Arm && Interventions

Group	Intervention	Description
control group	knotting methods	The volunteers in control group study traditional knotting technology,
new knotting group	knotting methods	The volunteers in experimental group study new knotting technology.

Primary Outcome Measures

Name	Time	Method
Accuracy of needle entry	through study completion, an average of 1 month	The needle stick should be in and out of the centre of the dot. The operator received 2 points if it was in the centre of the dot, 1 point if it deviated from the centre, and 0 points if it was outside the dot.
Stability of the knot	through study completion, an average of 1 month	The knot was required to be a surgical triple knot and should not have been a smooth knot or a loose knot. A normal knot received 2 points. A smooth knot received 1 point,and 0 points were awarded for a loose knot.
Tissue integrity	through study completion, an average of 1 month	The suture tissue should not be damaged or ruptured. The trainee received a score of two for integrity, 1 for a few cracks, and 0 for a complete fracture of the tissue.
Tightness of the tissue	through study completion, an average of 1 month	The tightness of the suture tissue indicated that the two sides of the sutured tissue were closely connected. The operator received 2 points if there was no gap between the two sides of the incision, 1 point for a few gaps, and 0 points for a totally loose suture.
