A laparoscopic forceps includes 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, and the tubular member disposed within the tubular member. A pair of jaws having legs projecting partially from the distal end of the tube, the pair of jaws and the tubular portion being relatively movable in a direction parallel to the longitudinal direction of the tubular member； Each of the pair of jaws has an arcuate section, and the pair of jaws can be closed by advancing the tubular member over the arcuate section of the jaws, and the laparoscopic forceps can be A steerable mechanism is included between the jaw and the tubular member that produces a relative movement along a direction parallel to the longitudinal axis of the tubular member, the contour shape being non-circular at the distal end portion of the tubular member.腹腔鏡鉗子は、遠位端部分を含むハンドピースと、ハンドピースの遠位端部分から突出する管状部材であって、遠位端を有する管状部材と、管状部材の中に配置され、管状部材の遠位端から部分的に突出する脚部を有する１対のジョーと、を含み、１対のジョーと管状部分とは、管状部材の長軸方向に平行な方向に相対移動可能であり、１対のジョーの各々はアーチ状区間を有し、１対のジョーは、ジョーのアーチ状区画を超えて管状部材を前進させることによって閉じることができ、また、腹腔鏡鉗子は、１対のジョーと管状部材の間に管状部材の長手方向軸に平行な方向に沿った相対移動を発生させる操作可能機構を含み、管状部材の遠位端部分において、輪郭形状は非円形である。
