PROBLEM TO BE SOLVED: To provide a medical device for stapling and cutting tissues according to an endoscope or laparoscope surgical procedure.SOLUTION: There is provided the medical device including a control handle having an articulation joint actuator, a surgical end effector, and a passive articulation joint for connecting the end effector to the control handle. Disclosed is a method for operating the end effector, in which the articulation joint actuator, when unactuated, holds the passive articulation joint and 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 force acting upon the end effector, wherein a step for retaining the passive articulation joint in a stable position with an articulation lock and actuating release of the articulation lock to unlock the passive articulation joint, permit articulating motion of the end effector through the passive articulation joint dependent upon the external force acting upon the end effector. |
