This study introduces a new laparoscopic surgical simulator using personal computers for realistic training. It features interactive organ simulation and force feedback instruments for minimally invasive surgery practice.

Area of Science:

  • Medical Simulation
  • Surgical Technology
  • Human-Computer Interaction

Background:

  • Minimally invasive surgery simulators have evolved since the 1990s, often requiring high-end workstations.
  • Limited availability of force feedback in existing surgical simulators restricts realistic training.
  • Advancements in personal computer technology enable more complex real-time simulations.

Purpose of the Study:

  • To develop an Intel-based laparoscopic surgical simulator for intuitive, near real-time interaction.
  • To create a training tool simulating cholecystectomy with interactive organ deformation and cutting.
  • To design and test input devices with force feedback mimicking surgical instrument manipulation.

Main Methods:

  • Development of an Intel-based personal computer surgical simulator.
