Patent ID: 8828046

Claim:
A surgical device, comprising: a frame having proximal and distal ends; an elongate shaft extending distally from the distal end of the frame; a mechanical transmission extending through the frame and elongate shaft, the transmission extending between an input joint at the proximal end of the frame and an output joint at a distal end of the elongate shaft, the transmission including at least one transmission plate disposed in the frame and slidably movable along a longitudinal axis of the device relative to the frame; an actuator extending distally from the proximal end of the frame, the actuator being coupled to the input joint and being polyaxially movable relative to the frame; and an end effector assembly positioned distal of the distal end of the elongate shaft, the end effector assembly being coupled to the output joint; wherein motion of the input joint is effective to cause correlating motion of the output joint such that movement of the actuator is mimicked by movement of the end effector assembly.
