This study introduces an image converter box (IC box) to eliminate mirror imaging during laparoscopy. The IC box significantly improves surgeon performance and task efficiency in laparoscopic procedures.

Area of Science:

  • Minimally Invasive Surgery
  • Surgical Technology
  • Human Factors in Medicine

Background:

  • Mirror imaging in laparoscopy causes paradoxical movements, hindering surgeon ergonomics and task performance.
  • This visual illusion is a common challenge for surgeons operating opposite the laparoscope.

Purpose of the Study:

  • To evaluate the effectiveness of a novel video image converter box (IC box) in overcoming mirror imaging during laparoscopic surgery.
  • To assess the impact of the IC box on surgeon performance and efficiency in laboratory-based laparoscopic tasks.

Main Methods:

  • Fourteen surgeons (10 novice, 4 experienced) performed three laparoscopic tasks (suture cutting, foam transfer, bean transfer) under mirror imaging conditions.
  • Task completion times were recorded with and without the use of the IC box.

Main Results:

  • Surgeons using the IC box completed all tasks significantly faster (P < 0.015), achieving completion in less than one-third the time.
  • In a complex task involving small object manipulation, 100% of surgeons succeeded with the IC box, compared to only 7% without it.

Conclusions:

  • The image converter box effectively eliminates mirror imaging, leading to improved laparoscopic task performance and efficiency.
  • The IC box offers significant benefits for surgeons working opposite the camera in laparoscopic procedures.
