Abstract
A fastener cartridge can include, one, a cartridge body comprising a deck and a plurality of fastener cavities and, two, a plurality of fasteners positioned in the fastener cavities. The deck can comprise features for controlling the flow of tissue relative thereto. In some instances, the features can support the fasteners as they are ejected from the fastener cavities.
Claims23
A fastener cartridge for use with a surgical instrument, wherein said fastener cartridge comprises:
- a proximal end;
- a distal end;
- a cartridge body comprising a deck, wherein a plurality of cavities are defined into said cartridge body in a plurality of longitudinal rows, wherein each longitudinal row comprises a proximal-most cavity and a distal-most cavity, wherein said proximal-most cavity is adjacent to said proximal end and said distal-most cavity is adjacent to said distal end, wherein each said cavity comprises an opening in said deck, and wherein said deck comprises a perimeter;
- a knife slot positioned intermediate said longitudinal rows, wherein said knife slot is configured to receive a longitudinally-progressing tissue cutting knife;
- a plurality of staples, wherein each said staple is removably positioned in a said cavity;
- and
- a rail positioned intermediate said plurality of cavities and said perimeter, wherein said rail spans between said proximal-most cavity and said distal-most cavity.
