This study introduces an advanced surgical suturing simulator for enhanced medical training. It features two-handed haptic feedback and realistic tissue modeling for improved surgical skill development.

Area of Science:

  • Medical Simulation
  • Surgical Training Technologies
  • Haptic Feedback Systems

Background:

  • Current surgical simulators lack realistic two-handed interaction and tactile feedback.
  • Existing models fail to accurately represent critical suturing conditions like skin undermining.
  • There is a need for advanced simulators to improve surgical education and patient safety.

Purpose of the Study:

  • To develop a next-generation immersive surgical suturing simulator.
  • To integrate two-handed haptic feedback for realistic tactile sensation.
  • To enhance simulation fidelity with advanced tissue and needle modeling.

Main Methods:

  • Development of an integrated two-handed, tension-based haptic device.
  • Implementation of a high-fidelity finite element model for skin, tissue, and needle dynamics.
