Abstract

A laparoscopic forceps comprising a handpiece including a distal end portion; a tubular member protruding from the distal end portion of the handpiece, the tubular member having a distal end, a pair of jaws having legs that are disposed within the tubular member and partially protruding from the distal end of the tubular member, the pair of jaws and the tubular member being movable relative to each other in a direction parallel to a longitudinal axis of the tubular member; wherein each of the pair of jaws has an arcuate section, and the pair of jaws are closable by advancing the tubular member over the arcuate section of the jaws; and an operable mechanism for creating relative motion between the pair of jaws and the tubular member along a direction parallel to the axis of the tubular member, wherein at the distal end portion of the tubular member there is a profile shape that is non-circular.
