ABSTRACT:
A surgical stapler anvil provides an expanded leg-receiving target area for a staple forming pocket in a compact staggered array by narrowing the lateral width of the leg-clinching portion of a laterally adjacent pocket. Advantageously, the lateral spacing between adjacent rows of staple forming pockets can remain small, while the leg-receiving target area for laterally adjacent rows of pockets is significantly expanded. The staple forming pockets include two mirror image leg-forming cups. The cups are longitudinally aligned with their respective ascending leg clinching portions adjoining in the center of the pocket. Laterally spaced guide surfaces extend upwardly and outwardly from the clinching surface at the bottom of the cup to define an expanded leg-receiving target area at the distal ends of the pocket. Substantially planar laterally outward portions of the guide surface intersect with the guide surface of a laterally adjacent pocket to form a non-linear ridge.
