Abstract

Summary form only given. During surgery, a surgeon uses a variety of surgical instruments. Therefore, a haptic interface should be able to display reaction force through various surgical instruments. Based on this concept, a novel encountered-type haptic interface using MR (Magneto-Rheological) fluid for surgical simulators have been developed. This haptic interface consists of a force display part using MR fluid and a motion table part which moves a container of the fluid. In this demonstration, the force display part is exhibited and visitors can experience demonstrations of cutting MR fluid with a knife. By changing intensity of current applied to electromagnetic coils, magnitude of resistance force can be changed. Also, they can feel vibrational force while sinusoidal current is applied. In addition, the role of the motion table is explained by showing behavior of MR fluid.
