A new laparoscopic pusher device significantly improves extracorporeal knot tying. It offers stronger knots, fewer failures, and faster tying times compared to traditional sliding knots, enhancing surgical efficiency.

Area of Science:

  • Surgical Technology
  • Minimally Invasive Surgery
  • Biomedical Engineering

Background:

  • Extracorporeal knot tying is a critical skill in laparoscopic surgery.
  • Current methods can be time-consuming and prone to failure.
  • Novel devices are needed to improve efficiency and reliability.

Purpose of the Study:

  • To evaluate the efficacy and feasibility of a novel pusher device for extracorporeal knot tying.
  • To compare the performance of the novel device with traditional knot-tying techniques.

Main Methods:

  • Three laparoscopists performed 10 device-assisted double sheet bends, 10 modified Roeder sliding knots, and 10 static surgeon's knots.
  • Knot strength and knotting time were measured for each technique.
  • Failure rates were recorded for each knot-tying method.

Main Results:

  • The device group demonstrated higher knot strength and a lower knotting failure rate compared to the sliding group.
  • Knotting time was significantly shorter in the device group than in the sliding group.
  • Knot strengths in the device group were comparable to the static group and superior to the sliding group.

Conclusions:

  • The novel laparoscopic pusher device is effective for extracorporeal knot tying.
  • The device offers advantages including steady and strong knot security, reduced failure rates, and decreased knotting time.
  • This innovation has the potential to enhance surgical performance in minimally invasive procedures.
