This study introduces a virtual reality module for laparoscopic surgery training, focusing on tissue dissection. It assesses performance using metrics like cut path deviation and instrument-tissue contact time.

Area of Science:

Medical Simulation
Surgical Training
Virtual Reality

Background:

Virtual environments are established for training surgical manipulative skills.
Tissue dissection training in virtual environments remains inadequately addressed.

Purpose of the Study:

To develop a virtual training module for laparoscopic tissue dissection.
To create performance metrics for assessing dissection skills in a simulated environment.

Main Methods:

Development of a virtual training module for dissecting a 3D tissue model.
Utilizing a simulated L-hook for dissection tasks.
Designing three performance metrics: cut path deviation, instrument-tissue contact time, and contact discontinuity.

Main Results:
