摘要：
A laparoscopic surgical device comprises an elongate shaft defining a longitudinal axis, the shaft comprising a distal end and a proximal end. A plurality of arms project distally from the distal end of the elongate shaft, the arms each comprising a lateral notch. The arms are axially slideable relative the elongate shaft and are medially deflectable. An elongate pin is positioned medially relative the arms. The elongate pin is axially slideable relative the arms between a locked position preventing medial deflection of the arms and an unlocked position allowing medial deflection of the arms. A surgical end effector is selectively attachable in vivo and detachable in vivo to the mating feature of the arms, the surgical end effector comprising a torque transfer means and tissue contact apparatus that open and close in response to the axial movement of the two arms when attached to the surgical end effector.
