Summary
A novel, homemade knot pusher, adapted from a right angle dissector, offers controlled tension for extracorporeal ties. This easily learned surgical tool proved safe and effective in thoracoscopic lobectomies and open surgery.
Area of Science:
- Surgical Instrumentation
- Minimally Invasive Surgery
- Thoracic Surgery
Background:
- Surgical knot tying, particularly for extracorporeal ties, requires specialized instruments.
- Existing knot pushers may offer limited control over applied tension.
- The need for adaptable and easily learnable surgical tools is ongoing.
Purpose of the Study:
- To describe the development and application of a modified, homemade knot pusher.
- To evaluate the efficacy and safety of this novel instrument for extracorporeal knot tying.
- To demonstrate its utility in both minimally invasive and open surgical procedures.
Main Methods:
- Modification of a conventional right angle dissector to create a functional knot pusher.
- Application of the homemade knot pusher for extracorporeal ties during surgical procedures.
- Testing in video-assisted thoracoscopic lobectomies and simulated deep wound scenarios.
Main Results:
- The homemade knot pusher allows for precise control over the tension applied to ligated structures.
- Successfully used in 10 video-assisted thoracoscopic lobectomies with over 100 applications on pulmonary vascular structures.
- No complications were reported during its use in these procedures.
Conclusions:
- This modified knot pusher is a cost-effective and easily learnable alternative for extracorporeal knot tying.
- The device offers significant advantages in tension control for ligating delicate structures.
- It is a versatile instrument applicable in both minimally invasive and open thoracic surgery.
