RADIALLY ADJUSTABLE SURGICAL INSTRUMENT FOR HEART SURGERY

摘要

This invention is a hand-held surgical instrument with an improved handle (10), and a tool (12) with a body member (21) having at least one articulated member (14) thereon. The handle has an elongated base (20), a lever (34) with an actuator arm (44), and a mechanism (48) for connecting the lever to the base at a pivot point which mimics the natural pivot point of the surgeon's hand. Closing of the lever causes distal movement of an actuator rod (56) which actuates the tool. The lever is biased in the open position. The lever may be locked in different positions. A collar (281) allows rotation and selective locking of the tool.
