Abstract
A surgical instrument comprises a shaft, a clamp support at a distal end of the shaft, and a clamp comprising a pair of pivotally mounted jaws within the clamp support. A handle at a proximal end of the shaft comprises an actuator for both opening and closing the jaws of the clamp and for rotating the jaws of the clamp about a deflected axis defined by the clamp support. The actuator includes a lever and a rotatable wheel which are coupled to the clamp via a flexible drive cable extending through the shaft and clamp support. The device is particularly useful for manipulating and driving curved surgical needles in thoracoscopic, laparoscopic, and other endoscopic suturing procedures.
