Minimally Invasive Surgery (MIS) training has been a challenge during the recent years, and Virtual Reality (VR) techniques provide a solution to that. In this method, human soft tissues are modeled in a virtual environment, and with the aid of an interface and graphical simulation, the surgeon performs a pre-determined operation in the virtual world. During the process, forces acting on the virtual tool are calculated in real-time, and fed back to the user via the interface. Therefore, the user has a “sense of touch” along with the graphics and animation. Obviously, the benefits are the safety and the ability of recording all operation data. The ultimate goal of the current project is to develop a virtual environment for training various laparoscopic surgery procedures in a more efficient manner. Also a haptic force feedback device is being designed and fabricated in order to provide the user with full immersion in the virtual environment.
