First Claim
Patent Images
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; and
an 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.

Abstract
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.

8. A surgical instrument, comprising:
-
a handle assembly, comprising; a first portion; and a 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; and an articulation actuator movable in said actuation plane, wherein said articulation actuator is configured to move said end effector relative to said shaft. - View Dependent Claims (9, 10, 11, 12, 13)

14. A surgical instrument, comprising:
-
a handle assembly, comprising; a first portion; and a 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; and an articulation actuator movable in said activation plane, wherein said articulation actuator is configured to actuate said articulation joint. - View Dependent Claims (15, 16, 17, 18, 19)
