Computer-based training system for simulating wrist arthroscopy

Abstract

The minimally invasive approach of arthroscopy means less pain and faster recovery time for patients compared to open surgery. However, it implies a high difficulty of performance. In this paper, a functional prototype of a computer-based training simulator for wrist arthroscopy is introduced. A 3-D virtual representation of the bones constituting the wrist of a patient is shown. Objects are modeled using the convex hull approaches and an algorithm to simulate real time collision detection during the training on the operation is presented. In addition, a force feedback device is used as a haptic interface with the computer simulation system. This leads in the development of a low cost system that is used by trainees with the same benefits as professional devices. In this regard, the wrist arthroscopy can be simulated and medical students can learn the basic skills required with safety, flexibility and less cost.
