Tissue thickness compensator having improved visibility
View Patent ↗A staple cartridge assembly for use with a surgical stapler. The assembly has a cartridge body having a support portion with a plurality of staple cavities with openings. There is also a plurality of staples, wherein at least a portion of each the staple is removably stored within a the staple cavity. Each the staple is movable between an unfired position and a fired position, and is deformable between an unfired configuration and a fired configuration. The assembly also includes a compressible tissue thickness compensator configured to be captured within the staples. The compressible tissue thickness compensator at least partially covers the staple cavity openings. The compressed tissue thickness compensator is configured to assume different compressed heights within different the staples. The compressible tissue thickness compensator includes a visualization indicator.
1. A staple cartridge assembly for use with a surgical stapler, wherein said staple cartridge assembly is adapted to be used with tissue having a thickness, said staple cartridge assembly comprising:
a cartridge body comprising a support portion, wherein said support portion comprises a plurality of staple cavities, and wherein each said staple cavity comprises an opening;
a plurality of staples, wherein at least a portion of each said staple is removably stored within a said staple cavity, wherein each said staple is movable between an unfired position and a fired position, and wherein each said staple is deformable between an unfired configuration and a fired configuration when each said staple is moved between a said unfired position and a said fired position; and
a compressible tissue thickness compensator configured to be captured within said staples, wherein said compressible tissue thickness compensator at least partially covers said staple cavity openings, and wherein said compressed tissue thickness compensator is configured to assume different compressed heights within different said staples, wherein said compressible tissue thickness compensator further includes a visualization means.
2. The staple cartridge assembly of claim 1 , wherein said visualization means comprises said tissue thickness compensator being formed at least partially from a radio opaque material.
3. The staples of claim 1 wherein said compressible tissue thickness compensator is a first color and said staples are a second color wherein said first and second colors are visually contrasting.
4. The staple cartridge assembly of claim 1 , wherein said compressible tissue thickness compensator comprises an uncompressed thickness which is thicker than the thickness of said tissue.
