Abstract
Laparoscopic surgery has the advantages that reducing patient' damages and risks of infection, and early rising. However, doctor is required special techniques in operation because of restricting significant information by endoscope or forceps. A training system for laparoscopic surgery is highly requested. Recently some training simulators are developed, but there are not many simulators with force feedback. We have focused on reflection force by operating forceps and developed the training simulator for the laparoscopic surgery. The simulator is based on the measured motion and dynamic properties of the forceps operated by skilled doctors.
