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

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 (cid:2)rst 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 (cid:2)ve 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.
