Abstract

This study investigates the operational influence of the force feedback with the five-finger robotic hand using master-slave control on surgery supporting system. We considered the tactile requirements of hand-assisted laparoscopic surgery (HALS) and specification of the surgery support robot and design the force feedback device. The device can feedback the corresponding force and will not obstruct the surgical behaviors. The device consisted of a mobile surface, which interacts with the fingertip, actuated by a wire directly connected to the motor. According to the result of our experiment, the dimension and the scratchability can be perceived through power grasp. In addition, when we execute the precision grasp, we can detect the exist of the organs.
