    • A surgical instrument for use in laparoscopy is provided, comprising a tubular member having a proximal end and a distal end, a first end effector piece pivotably mounted to the tubular member near the distal end of the tubular member, a second end effector piece disposed near the distal end of the tubular member and being slidable relative to the tubular member, wherein a surgical item, such as a suture needle, may be received between the first end effector piece and the second end effector piece and may be rolled substantially axially by axial translation of the second end effector piece with respect to the first end effector piece. In one embodiment, the end effector pieces may be provided with depressions in their face surfaces. In another embodiment, the surgical instrument may also include a handle assembly having a control lever and a rotation actuator. The tubular member may also be rotatably mounted on the handle. In another embodiment, the handle assembly may comprise a number of servomotors for effecting motion in the tubular barrel and the end effector pieces.
    • 提供了一种用于腹腔镜检查的手术器械,包括具有近端和远端的管状构件,在管状构件的远端可枢转地安装到管状构件的第一端部执行器件,设置在管状构件附近的第二端部执行器件 管状构件的远端并且可相对于管状构件滑动,其中外科物品(例如缝合针)可以容纳在第一端部执行器件和第二端部执行器件之间,并且可以通过轴向大致轴向地滚动 第二末端执行器片相对于第一末端执行器片的平移。 在一个实施例中,端部执行器件可以在其表面上设置有凹陷。 在另一个实施例中,外科器械还可以包括具有控制杆和旋转致动器的手柄组件。 管状构件也可以可旋转地安装在手柄上。 在另一个实施例中,手柄组件可以包括用于在管状筒体和端部执行器件中进行运动的多个伺服电动机。
