SURGICAL STAPLING DEVICE
First Claim
1. A surgical stapling device comprising:
- an elongated body portion;
a tool assembly having proximal and distal ends, and being pivotally connected to the body portion via a pivot member such that the tool assembly is pivotable about a pivot axis;
a firing cable having a proximal portion extending through the body portion, and a distal portion connected to the tool assembly; and
a knife bar directly connected to the distal portion of the firing cable, whereby distal movement of the distal portion of the firing cable causes corresponding distal movement of the knife bar.

Abstract
A surgical device is disclosed which includes a handle portion, a central body portion and a SULU. The SULU includes a proximal body portion, an intermediate pivot member and a tool assembly. The intermediate pivot member is pivotally secured to the proximal body portion about a first pivot axis and the tool assembly is pivotally secured to the intermediate pivot member about a second pivot axis which is orthogonal to the first pivot axis. The SULU includes a plurality of articulation links which are operably connected to the tool assembly by non-rigid links. The articulation links are adapted to releasably engage articulation links positioned in the central body portion. The body portion articulation links are connected to an articulation actuator which is supported for omni-directional movement to effect articulation of the tool assembly about the first and second axes. The handle portion includes a spindle and barrel assembly drive mechanism for advancing and retracting a drive member positioned in the tool assembly. In one embodiment, the tool assembly includes a cartridge assembly having a plurality of staples and an anvil assembly.
