Resterilized ultrasonic scissors demonstrate comparable reliability and function to new ones, offering significant cost reductions and improved efficiency in laparoscopic surgery. This makes them a viable option for surgical settings.

Area of Science:

  • Surgical Instrumentation
  • Medical Device Sterilization
  • Laparoscopic Surgery

Context:

  • Ultrasonic scissors are critical tools in minimally invasive surgery.
  • The cost-effectiveness of surgical instruments is a growing concern.
  • Evaluating the reliability of resterilized medical devices is essential for safe clinical practice.

Purpose:

  • To compare the functional reliability and handling of resterilized ultrasonic scissors against new, single-use disposable ones.
  • To assess key performance parameters including activation force, cutting and coagulation effects, and operational disturbances.
  • To determine the cost-efficiency and potential impact on surgical efficiency.

Summary:

  • A prospective randomized study evaluated 51 new and 49 resterilized ultrasonic scissors across 94 operations.

Related Experiment Videos

  • No significant differences were found in activation force, cutting effect, or coagulation between new and resterilized instruments.
  • Both groups exhibited rare error messages and noise, with a low exchange rate for both new (6) and resterilized (2) instruments.

    • Impact:

    • Resterilized ultrasonic scissors offer comparable reliability to new instruments.
    • Utilizing resterilized instruments significantly reduces surgical costs.
    • This practice can enhance overall efficiency in laparoscopic surgical procedures.
