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 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 operably supported adjacent said movable handle such that said articulation trigger may be operated by a same hand manipulating said movable handle.

Abstract
A surgical stapling apparatus. Various embodiments include a rotatable elongated body that extends from a rotatable shroud on handle assembly and has a distal end configured for attachment to a disposable loading unit. The apparatus further includes a lockable rotation system for selectively locking the rotatable shroud to prevent rotation thereof about a longitudinal axis.

8. A surgical stapling apparatus, comprising:
-
a handle assembly including a movable handle and a handle housing, the movable handle being movable through actuation strokes relative to said handle housing; an actuation shaft supported at least in part within said handle housing and mounted for longitudinal movement therein in response to manipulation of said movable handle through said actuation strokes; an elongated body protruding from said handle housing, said 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; an articulation system operably supported by said handle assembly and interfacing with said elongated body to selectively apply articulation motions thereto; and a selector arrangement interfacing with said movable handle, said actuation shaft and said articulation system such that when said selector arrangement is in a firing orientation, manipulation of said movable handle through said actuation strokes actuates said actuation shaft and when said selector arrangement is in an articulation orientation, manipulation of said movable handle through said actuation strokes actuates said articulation system. - View Dependent Claims (9, 10)

11. An articulation mechanism for a surgical stapling apparatus having a handle housing and an elongated body that protrudes from the handle housing and is configured to be operably coupled to an articulatable disposable loading unit that is responsive to axial motions transmitting by the elongated body, said articulation mechanism comprising:
-
a translation member movably supported within a portion of the handle housing for selective longitudinal movement therein, said translation member interfacing with the elongated body; and a rotatable cam disc rotatably supported by the handle assembly and interfacing with said translation member such that rotation of said cam disc in a first direction moves said translation member in a first axial direction and rotation of said rotatable cam disc in a second direction moves said translation member in a second axial direction. - View Dependent Claims (12, 13, 14, 15, 16)

17. An articulation mechanism for a surgical stapling apparatus having a handle housing and an elongated body that protrudes from the handle housing and is configured to be operably coupled to an articulatable disposable loading unit that is responsive to axial motions transmitted by the elongated body, said articulation mechanism comprising:
-
a translation member movably supported within a portion of the handle housing for selective longitudinal movement therein, said translation member interfacing with the elongated body; an articulation ring rotatably supported within a portion of the handle assembly and operably interfacing with said translation member such that rotation of said articulation ring within said handle housing in a first direction moves said translation member in a first axial direction and rotation of said articulation ring in a second direction moves said translation member in a second axial direction; and an articulation knob movably supported by said handle housing and interfacing with said articulation ring to impart rotary motions thereto. - View Dependent Claims (18, 19, 20)
