Summary

The Endo Clip II demonstrated superior security over the Ligaclip in laparoscopic surgery, requiring more force for clip dislodgment from tissues and tubing. Both devices showed no leakage during simulated blood circulation tests.

Area of Science:

  • Surgical Devices and Technology
  • Biomedical Engineering
  • Minimally Invasive Surgery

Background:

  • Laparoscopic surgery relies on secure closure devices.
  • Evaluating the performance of surgical clips is crucial for patient safety.
  • Two common clip appliers, Endo Clip II and Ligaclip, require comparative analysis.

Purpose of the Study:

  • To compare the in vitro security of the Endo Clip II and Ligaclip appliers.
  • To assess clip performance regarding dislodgment resistance and leakage.
  • To determine the force required for dislodging clips applied to silicone tubing and vascular tissue.

Main Methods:

  • In vitro testing of laparoscopic clip appliers (Endo Clip II, Ligaclip).
  • Dislodgment tests performed transversely and at 45 degrees on silicone tubing and porcine vascular tissue.

Related Experiment Videos

  • Leakage tests conducted under simulated pulsatile blood circulation (approx. 800 mm Hg).
  • Measurement of maximum force required for clip dislodgment.

    • Main Results:

    • Endo Clip II required significantly more force for transverse and 45-degree dislodgment compared to Ligaclip on silicone tubing and vascular tissue.
    • Transverse dislodgment forces for Endo Clip II on tissue (556 +/- 146 g) were higher than Ligaclip (356 +/- 170 g).
    • No leakage was observed with either clip applier on silicone tubing or tissue during pulsatile circulation tests.

    Conclusions:

    • The Endo Clip II exhibits superior mechanical security compared to the Ligaclip based on dislodgment resistance.
    • Both laparoscopic clip appliers provide equivalent, effective sealing against leakage in simulated surgical conditions.
    • These findings support the selection of Endo Clip II for enhanced security in laparoscopic procedures where clip integrity is paramount.
