Abstract
A medical device includes a surgical end effector, an end effector control handle, and a control shaft having a longitudinal axis and a handle portion connecting the control shaft to the control handle rotatably about the longitudinal axis. A passive articulation joint connects the end effector to the control shaft. An articulation joint release unlocks the articulation joint when actuated and locks the articulation joint when unactuated. An end effector control device is rotationally fixedly connected to at least a portion of the control shaft to correspondingly rotate the control shaft about the longitudinal axis when the control device is rotated and is longitudinally connected to the joint release to selectively unlock the articulation joint when actuated.
