A surgical stapling apparatus may comprise a handle assembly, a shaft, an end effector, an articulation joint, and an articulation actuator. The handle assembly comprises a first portion and a second portion moveable relative to the first portion. The end effector, connected to the shaft by the articulation joint, is configured to perform an end effector function when the second portion is actuated. The articulation actuator, which is configured to move the end effector relative to the shaft, and the second portion may be moveable in an actuation plane.

A surgical stapling apparatus, comprising: a handle assembly including a movable handle and a stationary handle housing, said movable handle being movable through actuation strokes in an actuation plane relative to said stationary handle housing;an actuation shaft supported at least in part withi
1. A surgical stapling apparatus, comprising: a handle assembly including a movable handle and a stationary handle housing, said movable handle being movable through actuation strokes in an actuation plane relative to said stationary handle housing;an actuation shaft supported at least in part within said handle housing and mounted to generate actuation motions in response to manipulation of said movable handle;an elongated body having a distal end configured to be operably attached to a disposable loading unit and a proximal end interfacing with said actuation shaft to transfer said actuation motions from said actuation shaft to said disposable loading unit; andan articulation system operably supported by said handle assembly and interfacing with said elongated body to selectively apply articulation motions thereto in response to manipulation of an articulation trigger in said actuation plane, said articulation trigger operably supported adjacent said movable handle such that said articulation trigger may be operated in said actuation plane by a same hand manipulating said movable handle. 2. The surgical stapling apparatus of claim 1 wherein said articulation trigger interfaces with said articulation system such that when said articulation trigger is moved in a first direction in said actuation plane, said articulation system applies a first articulation motion and when said articulation trigger is moved in a second direction in said actuation plane, said articulation system applies a second articulation motion. 3. The surgical stapling apparatus of claim 1 wherein said elongated body is operably supported relative to said handle assembly to enable said elongated body and disposable loading unit to be selectively rotated about an elongated axis. 4. The surgical stapling apparatus of claim 1 wherein said elongated body further comprises an articulation link movably supported therein and configured for attachment to an articulation portion of the disposable loading unit. 5. The surgical stapling apparatus of claim 4 further comprising an articulation bar constrained to move longitudinally within said handle housing and interfacing with said articulation trigger such that when said articulation trigger is moved in a first direction, said articulation bar transfers a first articulation motion to said articulation link and when said articulation trigger is moved in a second direction, said articulation bar transfers a second articulation motion to said articulation link. 6. The surgical stapling instrument of claim 1 wherein said articulation trigger is configured to be actuated by a user's index finger when the user is grasping a portion of the stationary handle housing. 7. The surgical stapling instrument of claim 6 wherein said articulation trigger has a ring portion for receiving a portion of the user's index finger therein. 8. A surgical instrument, comprising: a handle assembly, comprising: a first portion; anda second portion movable relative to said first portion in an actuation plane;a shaft extending from said handle assembly;an end effector configured to perform an end effector function, wherein the movement of said second portion in said actuation plane activates said end effector function;an articulation joint connecting said end effector to said shaft; andan articulation actuator movable in said actuation plane, wherein said articulation actuator is configured to move said end effector relative to said shaft. 9. The surgical instrument of claim 8, wherein said articulation actuator comprises an articulation trigger moveable in said actuation plane and said second portion comprises an actuation trigger moveable in said actuation plane. 10. The surgical instrument of claim 9, wherein said first portion comprises a gripping portion configured to make said actuation trigger and said articulation trigger operable with one hand. 11. The surgical instrument of claim 10, further comprising: an articulation link; andan articulation member coupled with said articulation link moveable by said articulation trigger to articulate said end effector. 12. The surgical instrument of claim 8, further comprising a staple cartridge supported by said end effector. 13. The surgical instrument of claim 8, wherein said articulation actuator comprises a ring portion which can be operably engaged by the user of said surgical instrument, and wherein said hand could also operably engage said actuation trigger. 14. A surgical instrument, comprising: a handle assembly, comprising: a first portion; anda second portion movable relative to said first portion in an activation plane;an end effector configured to perform an end effector function, wherein the movement of said second portion in said activation plane activates said end effector function;an articulation joint configured to permit said end effector to articulate about said articulation joint; andan articulation actuator movable in said activation plane, wherein said articulation actuator is configured to actuate said articulation joint. 15. The surgical instrument of claim 14, wherein said articulation actuator comprises an articulation trigger moveable in said activation plane and said second portion comprises an actuation trigger moveable in said activation plane. 16. The surgical instrument of claim 15, wherein said first portion comprises a gripping portion configured to make said actuation trigger and said articulation trigger operable with one hand. 17. The surgical instrument of claim 16, further comprising: an articulation link; andan articulation member coupled with said articulation link moveable by said articulation trigger to articulate said end effector. 18. The surgical instrument of claim 14, further comprising a staple cartridge supported by said end effector. 19. The surgical instrument of claim 14, wherein said articulation actuator comprises a ring portion which can be operably engaged by the user of said surgical instrument, and wherein said hand could also operably engage said actuation trigger.
