This study introduces a virtual reality (VR) trainer for colon cancer surgery, enhancing surgeon training with interactive 3D organ models and real-time simulation for improved surgical skills.

Area of Science:

  • Medical Simulation
  • Surgical Training
  • Virtual Reality

Background:

  • Colon cancer surgery requires precise manipulation of complex anatomical structures.
  • Current surgical training methods may lack immersive, interactive elements for practicing complex procedures.
  • Virtual reality (VR) offers a potential platform for realistic surgical simulation.

Purpose of the Study:

  • To develop an interactive VR-based trainer for colon cancer removal surgery.
  • To enable surgeons to virtually manipulate and interact with anatomical structures during simulated procedures.
  • To improve surgical training by providing a realistic and engaging simulation environment.

Main Methods:

  • Real-time animation of the small intestine and mesentery for interactive manipulation.
