Surgical stapling apparatus
CA 2571468 A1
Abstract
A surgical stapling apparatus having a handle assembly including a movable handle, which is movable through an actuation stroke. An elongated body extends distally from the handle assembly and defines a longitudinal axis. The elongated body having a distal end adapted to releasably engage both articulating and non-articulating disposable loading unit types. An actuation shaft is supported at least in part within the handle assembly and is mounted for longitudinal movement in response to manipulation of the actuation handle. An actuation mechanism includes an articulation lever mounted adjacent the handle assembly and an articulation link. The articulation link has a proximal end operatively connected to the articulation lever and a distal end positioned adjacent the distal end of the elongated body. A
sensing mechanism positioned within the elongated body and is operatively associated with the articulation mechanism. The sensing mechanism includes a sensing member for sensing the type of disposable loading unit engaged with the elongated body.

Claims(4)
1. A surgical stapling apparatus comprising:
(a) a handle assembly including a movable handle, the movable handle being movable through an actuation stroke;
(b) an elongated body extending distally from the handle assembly and defining a longitudinal axis, the elongated body having a distal end adapted to releasably engage both articulating and non-articulating disposable loading unit types;
(c) an actuation shaft supported at least in part within the handle assembly and mounted for longitudinal movement in response to manipulation of the actuation handle (d) an articulation mechanism including an articulation lever mounted adjacent the handle assembly and an articulation link, the articulation link having a proximal end operatively connected to the articulation lever and a distal end positioned adjacent the distal end of the elongated body; and (e) a sensing mechanism positioned within the elongated body and operatively associated with the articulation mechanism, the sensing mechanism including a sensing member for sensing the type of disposable loading unit engaged with the elongated body.
2. The surgical stapling apparatus according to claim 1, wherein the sensing member is movably positioned within the elongated body, the sensing member being movable to a first position in response to engagement of a non-articulating,disposable loading unit with the elongated body and to a second position in response to engagement of an articulating disposable loading unit with the elongated body.
3. The surgical stapling apparatus according to claim 2, wherein in the first position, the sensing mechanism is operatively engaged with the articulating mechanism to prevent movement of the articulating lever.
4. The surgical stapling apparatus according to claim 3, wherein the articulation mechanism includes a cam member having a stepped cam slot, the cam member being operatively positioned between the articulation lever and the articulation link.
