Assignee: CILAG GMBH INTERNATIONAL
Field: Medical technology (Instruments)
Classification: CPC A | IPC A

Claim 0:
1. A surgical instrument, comprising:
a handle;
a control system including a processor, a sensing system, and an electric motor;
a shaft extending from said handle;
an end effector, comprising:
a first jaw;
a second jaw rotatable relative to said first jaw;

an articulation joint, wherein said end effector is rotatable relative to said shaft about said articulation joint;
an articulation drive operable to rotate said end effector about said articulation joint when said articulation drive is in an activated operative state, wherein said articulation drive comprises:
an articulation driver operably coupled to said end effector, wherein said articulation driver is driveable by said control system;
a first articulation actuator in communication with said control system; and
a second articulation actuator in communication with said control system, wherein said control system is responsive to the actuation of said first articulation actuator and said second articulation actuator when said articulation drive is in the activated operative state;

a closure drive comprising:
a closure actuator movably coupled to said handle;
a closure tube movable from a proximal position to a distal position during actuation of said closure actuator from an unactuated position to an actuated position such that said closure tube moves said second jaw into a closed position when said closure tube is in the distal position, and wherein said sensing system is configured to detect when said closure tube is in the distal position; and
a releasable closure drive lock configured to:
engage said closure drive when said closure tube is in an intermediate position which is intermediate the proximal position and the distal position to hold said second jaw in a partially-closed position, wherein said articulation drive is in the activated operative state when said closure tube is in the intermediate position, and
engage said closure drive when said closure tube is in the distal position to hold said second jaw in the closed position, and wherein said control system deactivates said articulation drive into a deactivated inoperative state in which said control system is unresponsive to said first articulation actuator and said second articulation actuator when said sensing system detecs said closure tube is moved into said distal position.
