Development of a Guiding Endoscopy Simulator

Endoscopy simulators get more and more common for the training of physicians. It is important to make simulation as realistic as possible by providing optical, acoustical and haptical feedback. The haptic display of our simulator EndoSim allows applying active forces to all degrees of freedom and moving to defined positions. This positioning is used for our automatic guiding system. If the user asks for help, an algorithm calculates how to get over the next barrier, factoring forces and distances. The system is able to decide if it is wise to choose a longer way in order to reduce the force. The user gets either an optical help shown by signs or is guided directly by the automatically moved endoscope. This guiding system is a new possibility for teaching physicians to increase their examination capabilities.
