Abstract
A staple cartridge can comprise a plurality of staples positioned within a cartridge body, wherein the cartridge body can comprise a tissue-contacting deck and a plurality of ridges extending from the tissue-contacting deck. The ridges can be configured to prevent, or reduce the possibility of, tissue from moving relative to the staple cartridge during use. The staple cartridge can further comprise a plurality of staple cavities, wherein each staple cavity can comprise an opening in the deck which is at least partially surrounded by a ridge. The ridges can comprise a uniform height or a height which varies along the length thereof. The height can vary relative to a proximal end and a distal end of the cartridge body and/or between the center of the cartridge body and the side.
Claims25
A staple cartridge comprising:
- a plurality of staples;
- and
- a cartridge body, comprising:
- a middle portion;
- a lateral portion;
- a tissue-contacting deck;
- a plurality of staple cavities, wherein a said staple is positioned in each said staple cavity;
- and
- a plurality of ridges extending from said tissue-contacting deck, wherein each said ridge extends between said middle portion and said lateral portion, wherein said plurality of staple cavities comprises a first row of staple cavities housing a first row of staples and a second row of staple cavities housing a second row of staples, and wherein each said ridge extends along a line which transects said first row of staples and said second row of staples.
A staple cartridge, comprising:
- a plurality of staples;
- and
- a cartridge body, comprising:
- a tissue-contacting deck;
- a plurality of staple cavities, wherein each said staple cavity comprises an opening in said deck, and wherein a said staple is positioned in each said staple cavity;
- and
- a plurality of ridges extending from said tissue-contacting deck, wherein each said opening is at least partially surrounded by a said ridge, wherein each said ridge comprises an array of knurls, wherein said knurls cover the entirety of said tissue-contacting deck.
A staple cartridge, comprising:
- a plurality of staples;
- and
- a cartridge body, comprising:
- a tissue-contacting deck;
- a plurality of staple cavities, wherein each said staple cavity comprises an opening in said deck, and wherein a said staple is positioned in each said staple cavity;
- and
- a plurality of ridges extending from said tissue-contacting deck, wherein each said opening is at least partially surrounded by a said ridge, wherein said plurality of staple cavities comprises a row of staple cavities housing a row of staples, and wherein said ridges are positioned intermediate the staple cavities in said row of staple cavities.
A fastener cartridge, comprising:
- a plurality of fasteners;
- and
- a cartridge body, comprising:
- a tissue contacting deck;
- a row of fastener cavities, wherein each said fastener cavity comprises an opening in said deck, and wherein a said fastener is positioned in each said fastener cavity;
- and
- a plurality of projections extending from said deck, wherein each said opening is at least partially surrounded by a said projection, and wherein at least a portion of a said projection is positioned intermediate adjacent fastener cavities in said row of fastener cavities.
A fastener cartridge, comprising:
- a plurality of fasteners;
- and
- a cartridge body, comprising:
- a proximal end;
- a distal end;
- a tissue contacting deck;
- a plurality of fastener cavities, wherein a said fastener is positioned in each said fastener cavity;
- and
- a plurality of projections extending from said deck, wherein at least a portion of a said projection is positioned between said fastener cavities, wherein each said projection comprises a height which varies between a proximal height and a distal height, and wherein said proximal height is closer to said proximal end than said distal height.
A fastener cartridge, comprising:
- a cartridge body, comprising:
- a tissue contacting deck;
- a plurality of fastener cavities at least partially defined in said deck;
- and
- a plurality of projections extending from said deck, wherein said projections are positioned intermediate said fastener cavities, and wherein said projections at least partially surround said fastener cavities;
- and
- a plurality of fasteners.
A fastener cartridge, comprising:
- a cartridge body, comprising:
- a tissue contacting deck;
- at least one row of fastener cavities extending between a proximal fastener cavity and a distal fastener cavity;
- and
- a plurality of projections, wherein said projections are at least partially positioned within said row of fastener cavities;
- and
- a plurality of fasteners.
A fastener cavity, comprising:
- a plurality of fasteners;
- and
- a cartridge body, comprising:
- a tissue contacting deck;
- a row of fastener cavities, wherein a said fastener is positioned in each said fastener cavity, and wherein each said fastener cavity comprises a rim;
- and
- a plurality of projections extending from said deck, wherein said projections are positioned intermediate said fastener cavities, and wherein said projections extend along at least a portion of said rims of said fastener cavities.
