Abstract
One example of a surgical stapler may include a pusher, at least one generally planar staple, where the pusher holds at least one staple, and a splay arm that includes spaced-apart splay fingers extending generally distally, where at least one splay finger includes a splay tip extending therefrom, and where relative motion of said pusher and said splay fingers causes said at least one said splay tip to engage and then splay at least one said staple. Another example of a surgical stapler may include a plurality of staples positioned out of contact with one another; a pusher that engages each staple; and at least one splay tip, each splay tip configured to contact a distal surface of the distalmost staple. Another example of a surgical stapler may include a plurality of staples, a pusher that holds the staples, the pusher having a longitudinal axis and being slidable longitudinally both proximally and distally substantially along that longitudinal axis, where the pusher is substantially constrained against motion away from the longitudinal axis; and a splay arm movable in a direction away from the longitudinal axis, from a position in which the splay arm contacts one staple to a posi…
