腹腔镜夹钳组件
摘要：
一种腹腔镜夹钳，该腹腔镜夹钳包括：机头，该机头包括远端部；管状构件，该管状构件从机头的远端部突出，管状构件具有远端，该远端具有远端开口；一对钳夹，该钳夹具有设置在管状构件内并且部分地从远端开口突出的腿部，钳夹和管状构件可相对于彼此移动；其中，所述钳夹中的每一个钳夹都具有弓状段；可操作机构，该可操作机构用于在钳夹与管状构件之间产生沿平行于纵轴线的方向的相对运动；以及一个或多个间隔件，所述一个或多个间隔件横过管状构件的远端开口并且在钳夹之间延伸；其中，所述钳夹能这样闭合：通过管状构件和钳夹朝着彼此的相对移动，使得管状构件在钳夹的弓状段上前进；并且所述钳夹能这样打开：通过管状构件和钳夹彼此远离的相对移动，使得所述一个或多个间隔件在钳夹之间延伸而使得钳夹张开。
摘要（英）：

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 with a distal opening, a pair of jaws having legs that are disposed within the tubular member and partially protruding from the distal opening, the jaws and the tubular member being movable relative to each other; wherein each of the jaws has an arcuate section; an operable mechanism for creating relative motion between the jaws and the tubular member along a direction parallel to the longitudinal axis, and one or more spacing members extending across the distal opening of the tubular member and between the jaws; wherein the jaws are closable by the relative movement of the tubular member and the jaws towards each other so that the tubular member advances over the arcuate section of the jaws, and the jaws are openable by the relative movement of the tubular member and the jaws away from each other so that the one or more spacing members extend between the jaws and the jaws are moved apart.
