Claim Text:
1. A laparoscopic surgical instrument comprising: a) a tubular body portion having a primary section defining a longitudinal axis, an angularly offset proximal section defining a proximal axis extending at an obtuse angle to the longitudinal axis of the primary section, and a distal housing section; b) an end effector operatively associated with the distal housing section of the tubular body portion for performing a surgical task, the end effector including a pair of cooperating jaw members, a dynamic pivot pin connecting the jaw members to one another, and a stationary cam pin supported within the distal housing section and positioned within oppositely angled cam slots formed in the jaw members; c) a handle assembly operatively associated with the proximal section of the tubular body portion for actuating the end effector; and d) an actuation shaft extending through the tubular body portion and configured to transfer force between the handle assembly and the end effector, the actuation shaft extending to a distal link connected to the dynamic pivot pin of the end effector, wherein linear movement of the distal link within the distal housing section causes corresponding linear movement of the dynamic pivot pin and jaws members relative to the stationary cam pin, causing the jaw members to move between open and closed positions.
