Surgical stapling apparatus with articulatable components
First Claim
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; and
an elongated body assembly comprising;
a proximal body segment protruding from said handle assembly and interfacing with said actuation shaft;
a distal body segment configured to be operably attached to a disposable loading unit; and
an intermediate articulation joint coupling said distal body segment to said proximal body segment such that said proximal body segment and said distal body segment define a longitudinal axis and wherein said intermediate articulation joint enables said distal body segment to be selectively pivoted about an intermediate articulation axis that is substantially transverse to said longitudinal axis, and wherein said elongated body assembly is configured to transfer said actuation motions from said actuation shaft to the disposable loading unit.

Abstract
A surgical stapling apparatus for use with a disposable loading unit. Various embodiments include an elongated body assembly that comprises a distal body segment and a proximal body segment that are operably coupled together by an intermediate articulation joint such that the proximal body segment and the distal body segment define a longitudinal axis. The intermediate articulation joint may be configured to facilitate articulation of the distal body segment about an intermediate articulation axis that is substantially transverse to the longitudinal axis. The elongated body assembly may be configured to transfer actuation motions from an actuation shaft housed in a handle assembly to the disposable loading unit. In various embodiments, the intermediate articulation joint may be adjacent to the handle assembly.

14. 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; and an elongated body assembly comprising; a proximal body segment protruding from said handle assembly and interfacing with said actuation shaft, said proximal body segment having a ball segment formed on a distal end thereof; and a distal body segment having a distal end configured to be operably attached to a disposable loading unit, said distal body segment further having a socket formed on a proximal end thereof, said socket sized to rotatably receive said ball segment therein; and an articulation system at least partially supported by said handle assembly and interfacing with said distal body segment of said elongated body assembly to selectively transmit at least one articulation motion to said distal body segment to cause said distal body segment to articulate in a first plane, said articulation system being further configured to selectively transmit at least one other articulation motion to said distal body segment to cause said distal portion to articulate in a second plane that is substantially orthogonal to said first plane. - View Dependent Claims (15, 16)
