摘要：A surgical instrument particularly suited to endoscopic articulates an endeffector by including an end effector having a geared articulation mechanism thatconverts rotational motion from a handle portion. A hollow articulation drive tubetransfers the rotation motion in some versions to a spear gear, bevel gear or snaggletooth gear articulation mechanism. Alternatively, one or more threaded drive rod offsetfrom a longitudinal axis engages a worm gear or flex-neck articulation mechanism.
