ARTICULATABLE SURGICAL INSTRUMENT COMPRISING A FIRING DRIVE
First Claim
1. A surgical instrument for treating tissue, comprising:
- a handle comprising a trigger;
a shaft extending from said handle;
an end effector;
an articulation joint, wherein said end effector is rotatably coupled to said shaft by said articulation joint;
a firing member operably coupled with said trigger, wherein the operation of said trigger is configured to advance said firing member toward said end effector; and
an articulation member operably coupled with said end effector, wherein said articulation member is selectively engageable with said firing member such that said articulation member is operably engaged with said firing member in an engaged configuration and such that said articulation member is operably disengaged from said firing member in a disengaged configuration, and wherein said firing member is configured to move said articulation member relative to said end effector to rotate said end effector about said articulation joint when said articulation member and said firing member are in said engaged configuration.

Abstract
A surgical instrument can comprise a handle, a shaft extending from the handle, and an end effector rotatably coupled to the shaft by an articulation joint. The surgical instrument can further include a staple cartridge positioned within the end effector and a firing drive operably coupled with a trigger wherein the operation of the trigger can advance and/or retract a firing member of the firing drive relative to the end effector. The surgical instrument can further comprise an articulation drive which is selectively engageable with the firing drive. When the articulation drive is engaged with the firing drive, the operation of the firing drive can operate the articulation drive and articulate the end effector. When the articulation drive is not engaged with the firing drive, the firing drive can be operated independently of the articulation drive.

26. A surgical stapling instrument for treating tissue, comprising:
-
an electric motor; a shaft; an end effector; an articulation joint, wherein said end effector is rotatably coupled to said shaft by said articulation joint; a firing drive operably engageable with said electric motor, wherein said firing drive is configured to be advanced toward said end effector and retracted away from said end effector by said electric motor; and an articulation drive operably coupled with said end effector, wherein said articulation drive is configured to articulate said end effector in a first direction when said articulation drive is pushed distally toward said end effector, wherein said articulation drive is configured to articulate said end effector in a second direction when said articulation drive is pulled proximally away from said end effector, wherein said firing drive is selectively engageable with said articulation drive and is configured to push said articulation drive distally toward said end effector or pull said articulation drive away from said end effector when said firing drive is operably engaged with said articulation drive, and wherein said firing drive can be operated independently of said articulation drive when said firing drive is operably disengaged from said articulation drive. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33)
