This study introduces LapSkills, a modular surgical simulator enabling dynamic, reusable simulations for various procedures. This approach facilitates patient-specific virtual environments and accelerates the development of diverse laparoscopic surgical training modules.

Area of Science:

  • Medical Simulation
  • Surgical Training
  • Virtual Reality in Medicine

Background:

  • Current surgical simulators use fixed, anatomy-based virtual environments (VE).
  • This rigidity limits simulator reusability for different surgeries and patient-specific cases.
  • Difficulty in adapting VE for individual patient anatomy hinders personalized simulation.

Purpose of the Study:

  • To demonstrate the reusability of a modular skill-based simulator, LapSkills.
  • To enable dynamic generation of surgery-specific simulations.
  • To facilitate patient-specific simulation by allowing VE replacement.

Main Methods:

  • Developed LapSkills, a modular, skill-based simulator.
  • Reused task and instrument modules for dynamic simulation generation.
