This study develops a haptic simulator for trocar insertion training. The device aims to reduce injuries by providing tactile feedback, improving surgical skill and safety.

Area of Science:

  • Surgical simulation
  • Medical device development
  • Haptic technology

Background:

  • Trocar insertion is a critical micro-surgery step often learned without visual feedback.
  • Excessive force during insertion is a primary cause of surgical injuries.
  • Current training methods lack tactile feedback for this procedure.

Purpose of the Study:

  • To develop a haptic-based simulator for trocar insertion training.
  • To enhance surgical skill acquisition and reduce insertion-related injuries.
  • To investigate force modeling and trocar-tissue interactions for simulation.

Main Methods:

  • Development of a novel haptic feedback system for trocar insertion.
  • Modeling of trocar-tissue interactions to simulate tactile sensations.
