Virtual Resectoscope Interface for a Surgery Simulation Training System of the Prostate

Abstract

In this work is presented the current state of the development of a virtual resectocope interface for a surgery simulation system for training Transurethral Resection of the Prostate (TURP). The interface consists of two parts, the first part is a mechatronics device that emulates a real resectosope and allows to perform the most important movements of the surgical tool during a TURP. The second part is a software interface that consist on a collision detection mechanism that allows to calculate in real-time the interactions between the mechatronic device and the deformable tissue model of the prostate, in order to simulate tissue resection and deformation. The current prototype has five degrees of freedom, which are enough to have a realistic simulation of the surgery movements. The results show that the interface is suitable for a real-time surgery simulation training system of the prostate without force feedback.
