Computer Assisted Surgical Training (CAST)

Introduction

The Computer Assisted Surgery Trainer was designed by our partners at the Model Based Design Laboratory (MBDL) at the Department of Electrical and Computer Engineering, University of Arizona. Using sensors for precise tracking of laparoscopic instrument movements, this training system is able to calculate key instrument metrics including total path length, average speed, instantaneous speed, average radius of motion and the number of times "safety zones" were breached. This assessment method provides a more objective approach to surgical education. Developments were made to integrate sensing and configuration space methods that provide movement guidance and haptic feedback to reinforce an optimal instrument trajectory and help trainees avoid potentially harmful aberrant movement. Currently, work is being done on CAST III, which will incorporate the optimal path navigation system with augmented reality visualization. We envision that CAST will eventually be used in real time to help guide laparoscopic surgeons during actual procedures.
