Area of Science:

  • Medical Simulation
  • Surgical Training
  • Human-Computer Interaction

Background:

  • Current surgical simulators often rely on expensive, specialized sensory equipment for instrument tracking.
  • The Leap Motion controller offers a low-cost alternative with high-accuracy linear object tracking.
  • Investigating its potential for laparoscopic skills assessment is crucial for accessible surgical training.

Purpose of the Study:

  • To evaluate the feasibility of a virtual reality (VR) simulator using the Leap Motion controller for assessing fundamental laparoscopic skills.
  • To compare the performance of expert and novice surgeons in VR-based laparoscopic tasks.
  • To assess the face validity and training value of the developed VR system.

Main Methods:

  • Developed a VR simulator with a custom interface and tools for laparoscopic procedures.
  • Implemented three core VR tasks: camera navigation (CN), instrument navigation (IN), and bimanual operation (BO).
  • Recruited 28 expert and 21 novice surgeons across two simulation centers for task performance and feedback.

Main Results:

  • Expert surgeons significantly outperformed novices in instrument navigation (IN) and bimanual operation (BO) metrics (p < 0.05).
  • Significant differences were observed in camera navigation (CN) for one error metric (p < 0.05).
  • Qualitative analysis indicated experts used more delicate movements, and participants rated the system's training value highly.

Conclusions:

  • The Leap Motion controller shows significant potential for assessing basic laparoscopic skills in a VR environment.
  • The system effectively evaluates hand movement dexterity, offering a valuable tool for surgical training.
  • Future research should include comparative studies with validated simulators and development of advanced training scenarios.
