Mechatronic Resectoscope Emulator for a Surgery Simulation Training System of the Prostate

Abstract

In this work is presented the development of a mechatronic interface for a surgery simulation system for training Transurethral Resection of the Prostate (TURP). The interface emulates a real resectosope and allows to perform the most important movements of the surgical tool during a TURP. The interface is able to work in conjunction with a virtual reality software with a 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.

Virtual reality for medical training: the state-of-the-art

“…Padilla et al (2007) report on a novel haptic interface mechatronic resectoscope simulator. At 44 ms or approximately 23 Hz, the response time of the movements monitoring is significantly below the accepted haptic refresh rate (1 kHz) required for stable haptic rendering.…”

Building a three-dimensional model of the upper gastrointestinal tract for computer simulations of swallowing

“…This possibility alone justifies developing virtual endoscopy, for resident training, with a view to acquire skills in swallowing evaluation and for patient training through feedback. In motivations (B) and (C) the computer simulation of interactions of soft tissue with surgical instruments requires deformable, multilayer models, featuring viscous-elastic properties [21]. The basis for such dynamic models is a tetrahedral mesh, which constitutes the next-complexity layer on a triangular-mesh model.…”
