Patent Images
1. A surgical stapling apparatus comprising:
- a handle assembly including a movable handle, the movable handle being movable through at least one actuation stroke;
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 loading unit types;
an actuation shaft mounted for longitudinal movement in response to manipulation of the movable handle; and
an articulation mechanism mounted adjacent the handle assembly and an articulation link, the articulation link having a distal end positioned adjacent the distal end of the elongated body.

Abstract
A surgical stapling device particularly suited for endoscopic procedures is described. The device includes a handle assembly and an elongated body extending distally from the handle assembly. The distal end of the elongated body is adapted to engage a disposable loading unit. A control rod having a proximal end operatively connected to the handle assembly includes a distal end extending through the elongated body. A control rod locking member is provided to prevent movement of the control rod until the disposable loading unit is fully secured to the elongated body of the stapling device.

6. A surgical stapling apparatus comprising:
-
a) a handle assembly including a movable handle supported by the handle assembly, the movable handle being movable through at least one actuation stroke;
b) an elongated body extending distally from the handle assembly and defining a longitudinal axis, a tool assembly being disposed adjacent a distal end of the elongated body; and
c) an advancement assembly including an actuation shaft, a driving pawl and a locking pawl, the actuation shaft having teeth and being supported at least in part within the handle assembly, the driving pawl being operatively associated with the movable handle and movable into engagement with the actuation shaft to effect longitudinal advancement of the actuation shaft during the actuation stroke, the locking pawl being biased into engagement with the rack to retain the actuation shaft in a longitudinally fixed position. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13)
