This study introduces a new haptic rendering technique for realistic scissor cutting simulation. It enhances surgical simulators by providing accurate force feedback during cutting actions.

Area of Science:

  • Surgical simulation
  • Haptic rendering
  • Robotics

Background:

  • Current surgical simulators lack realistic force feedback during scissor cutting.
  • Operator "between the fingers" forces are not displayed in existing simulations.

Purpose of the Study:

  • Develop a fast, realistic haptic rendering technique for scissor cutting.
  • Integrate the technique into soft tissue models for surgical simulators.

Main Methods:

  • Created a virtual environment for combined graphic and haptic display.
  • Developed two 2D deformable mass-spring-damper models for translational and cutting forces.
  • Implemented the technique on haptic scissors for motion and force feedback.

Main Results:
