Abstract
A medical device includes a control handle having an articulation joint actuator, a surgical end effector, and a passive articulating joint connecting the end effector to the control handle. The articulation joint actuator, when unactuated, holds the passive articulation joint and, thereby, the end effector, in a substantially fixed articulation position, and, when actuated, releases the passive articulation joint into a freely articulating state to permit free articulation of the end effector with respect to the control handle dependent upon external forces acting upon the end effector. A method for operating the end effector includes retaining the passive articulation joint in a stable position with an articulation lock and actuating a release of the articulation lock to unlock the passive articulation joint and, thereby, permit articulating motion of the end effector through the passive articulation joint dependent upon the external forces acting upon the end effector.
