Design of a Tendon-Sheath-Driven Robot with Proportional Control for Medical Surgery

Article Preview

Abstract:

To reduce the trauma to human body in traditional medical surgery and improve the precision of surgical operation, a Tendon-Sheath-Driven robot is designed in this paper. With Tendon-Sheath-Driven mechanism, the robot is composed of head actuator and tailing box. The structure of the head actuator is similar to the tailing box, but much smaller than the later. In the operation process, the head actuator will proportionally cope the motions what operator does, moreover, with sensors installed on each joint of the tailing box, through proportion conversion, doctors can get the parameter variables of each joint on the head actuator easily. Therefore, together with endoscopic, the robot can play an important part in modern medical surgery.
