CAD-based graphical computer simulation in endoscopic surgery.
This article presents new techniques for three-dimensional, kinematic realtime simulation of dextrous endoscopic instruments. The integrated simulation package KISMET is used for engineering design verification and evaluation. Geometric and kinematic computer models of the mechanisms and the laparoscopic workspace were created. Using the advanced capabilities of high-performance graphical workstations combined with state-of-the-art simulation software, it is possible to generate displays of the surgical instruments acting realistically on the organs of the digestive system. The organ geometry is modelled in a high degree of detail. Apart from discussing the use of KISMET for the development of MFM-II (Modular Flexible MIS Instrument, Release II), the paper indicates further applications of realtime 3D graphical simulation methods in endoscopic surgery.
