摘要：
A surgical device comprises an elongate shaft comprising an outer tube and an inner rod positioned in the outer tube, the outer tube and inner rod each comprising a distal end and a proximal end. An actuator is operably connected to the proximal ends of the outer tube and the inner rod. An end effector is adapted for in vivo attachment to and detachment from the elongate shaft. The end effector comprises an outer casing comprising a mating feature adapted to attach to the distal end of the outer tube an inner shuttle axially moveable relative the outer casing, the shuttle comprising a magnetic material providing provisional engagement to the distal end of the inner rod a pair of surgical jaws having an opened position and closed position dependant on the relative axial position of the shuttle and casing. The surgical device may further comprise a collet on the distal end of the inner rod adapted to lock onto the shuttle.
