Abstract
A motor-driven prosthetic prehensor includes an upright annular member and an annular retaining member having a friction wall that defines an accommodation space with a front wall of the annular member. A coupling sleeve member with a toothed rim is rotatably mounted on a transmission shaft disposed rotatably in the annular member, and has angularly spaced driving blocks extending into the accommodation space. A coupling member is mounted on and rotatable with the transmission shaft, and includes radially spaced driven spacer members that cooperate with the friction wall to define a plurality of chambers for receiving the driving blocks, and friction brakes that are slidable in the chambers between unobstructed position and braked positions. A coupling mechanism transmits rotation of the transmission shaft to drive a thumb member and a fingers assembly to move toward and away from each other so as to grasp or release an object.
