Abstract
A surgical instrument for use in laparoscopic surgical procedures is disclosed that includes an elongated shaped outer shaft having opposed proximal and distal end portions, and having a non-circular cross-sectional profile, an end effector operatively associated with a distal end portion of the shaped outer shaft and including a pair of cooperating jaw members configured for movement between open and closed positions, a proximal handle assembly operatively associated with a proximal end portion of the shaped outer shaft and including a pivoting actuation handle, and an elongated actuation member extending through the shaped outer shaft from the proximal handle assembly to the end effector, whereby movement of the actuation handle causes corresponding movement of the cooperating jaw members.
