    摘要: A surgical instrument comprising an end effector, the end effector comprising first and second opposing jaw members, wherein at least one of the first and second jaw members are moveable such that the first and second jaw members are transitionable between open and closed positions. The first jaw member may comprise a permanent magnet. The second jaw member may also comprise a magnet (e.g., permanent or soft). The magnetic motive force between the magnets of the first and second jaw members may attract each other to thereby reduce the external force required to transition the first and second jaw members to the closed position. In addition, the magnets may be configured to repeal each other to thereby aid in opening the jaw members.
