Area of Science:

  • Medical simulation
  • Surgical training
  • Virtual reality

Background:

  • Minimally invasive surgery presents challenges due to limited visualization and poor tactile feedback.
  • Effective training tools are crucial for medical students in early clinical education.
  • Virtual reality (VR) surgical simulators offer a promising solution for skill development.

Purpose of the Study:

  • To develop and evaluate a visuohaptic surgery training system for laparoscopic techniques.
  • To enhance the learning experience for medical students in minimally invasive surgery.

Main Methods:

  • Recorded expert surgeon's first-person video and instrument trajectory data.
  • Developed a VR system displaying recorded video and providing guidance force feedback to trainees.
