Abstract
A surgical stapling device includes a tool assembly that includes a staple cartridge having a cartridge body that defines a central knife slot, rows of first staple receiving pockets on one side of the central knife slot, and a row of second staple receiving pockets on a second side of the knife slot. The first staple receiving pockets receive staples having a substantially U-shaped configuration that can be formed into a B-shape. The second staple receiving slots receive substantially Y-shaped staples which minimize damage to tissue and can be removed from the tissue more easily to allow for pathological examination of the tissue.
