  • Patent number: 9987011
    Abstract: A surgical stapler is provided. The stapler includes a tubular body portion. A cartridge assembly is disposed at a distal end of the body portion for expelling an annular array of staples. Each of the staples of the annular array of staples has a generally bent backspan. An anvil member disposed at the distal end of the tubular body portion is positioned opposite the cartridge assembly to clinch the staples in tissue upon expulsion of the staples from the cartridge assembly. The anvil member has a corresponding annular array of staple forming buckets. Each of the buckets is configured to accommodate the generally bent configuration of the staples to facilitate formation thereof.

    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.
