摘要:
In various embodiments, a stapling assembly is disclosed. The stapling assembly comprises, among other things, an anvil configured to deform staples. The anvil comprises a tissue-engaging surface and a pair of forming pockets defined in the tissue engaging surface, wherein the pair of forming pockets is configured to deform the legs of a staple. The forming pockets comprise, one, a proximal forming pocket comprising a forming surface, wherein the forming surface comprises an entry zone comprising a first radius of curvature and an exit zone comprising a second radius of curvature, wherein the first radius of curvature and the second radius of curvature comprise a ratio of 1.5:1 to 3:1, and wherein the first radius of curvature is between 8 times and 10 times larger the staple diameter and, two, a distal forming pocket.
