Simple Extracorporeal Knot-Tying Technique in Minimal Access Surgery

Area of Science:

• Minimally Invasive Surgery
• Surgical Techniques
• Biomaterials

Background:

• Extracorporeal knot tying presents significant challenges in minimally invasive surgery.
• Existing methods often suffer from mechanical failures, user errors, and reduced haptic feedback.
• Suture fraying and a steep learning curve are common issues with current surgical aids.

Purpose of the Study:

• To describe a novel, conventional technique for extracorporeal knot tying.
• To address the limitations of current surgical knot-tying aids.
• To provide a simple, cost-effective solution with a short learning curve.

Main Methods:

• A conventional technique utilizing a polytetrafluoroethylene (PTFE) pledget is described.
• The PTFE pledget is used to assist in lowering the surgical knot.
• The technique ensures no direct contact between the suture and the surgical instrument.

Main Results:

• Eliminates suture fraying and tearing by preventing instrument-suture contact.
• Offers a simple and inexpensive solution for extracorporeal knot tying.
• Demonstrates an extremely short learning curve for surgical practitioners.

Conclusions:

• The described PTFE pledget technique offers a significant improvement over existing methods for extracorporeal knot tying.
• This technique enhances surgical efficiency and reduces potential complications in minimally invasive procedures.
• Its simplicity, low cost, and ease of use make it a valuable tool for surgeons.
