SURGICAL STAPLER ANVILS WITH STAPLE DIRECTING PROTRUSIONS AND TISSUE STABILITY FEATURES

An anvil for a surgical stapler is disclosed. The anvil includes a staple-forming undersurface that has lines of staple-forming pockets that are configured to establish a flexible staple line. A plurality of anvil protrusions protrude from planar non-forming surface portions such that each anvil protrusion is adjacent to at least two staple-forming pockets to direct staples therein during a staple firing process and to engage the tissue that is being stapled. 本发明公开了一种用于外科缝合器的砧座。该砧座包括钉成形下表面，该钉成形下表面具有被构造成能够建立柔性钉线的多排钉成形凹坑。多个砧座突起从平坦的非成形表面部分突起，使得每个砧座突起与至少两个钉成形凹坑相邻，以在钉击发过程期间在其中引导钉并且接合正被缝合的组织。
