Staple cartridge comprising a staple driver arrangement
An end effector comprising a first jaw, a second jaw, a plurality of staple cavities, a plurality of staples removably positioned in the staple cavities, and a translatable member is disclosed. One of the first jaw and the second jaw is movable between an open position and closed positions relative to the other of the first jaw and the second jaw. The translatable firing member comprises a first portion configured to engage the first jaw, a second portion configured to engage the second jaw, and an attachment configured to contact one of the first jaw and the second jaw. The first portion is comprised of a metal. The attachment is comprised of a resilient material.
1. A disposable end effector for use with a surgical stapling instrument including a shaft, said disposable end effector comprising:
a proximal end configured to be attached to the shaft of the surgical stapling instrument;
a distal end;
a first jaw;
a second jaw rotatably pivotably coupled relative to said first jaw, wherein one of said first jaw and said second jaw is movable between an open position and a closed position relative to the other of said first jaw and said second jaw;
a plurality of staple cavities;
a plurality of staples, wherein said staples are removably positioned in said staple cavities; and
a tissue cutting member movable toward said distal end, wherein said tissue cutting member comprises:
a cutting edge;
a first camming member configured to engage said first jaw;
a second camming member configured to engage said second jaw, wherein said first camming member and said second camming member are configured to co-operatively set a tissue gap between said first jaw and said second jaw; and
an affix extending from one of said first camming member and said second camming member, wherein said affix is configured to facilitate in setting the tissue gap between said first jaw and said second jaw, and wherein said affix is made of a resilient material.
2. An end effector for use with a surgical stapling instrument including a shaft, said end effector comprising:
a proximal end configured to be attached to the shaft of the surgical stapling instrument;
a distal end;
a pair of jaws, comprising:
a first jaw; and
a second jaw, wherein one of said first jaw and said second jaw is movable between an open condition and a closed condition relative to the other of said first jaw and said second jaw;
a plurality of staple cavities;
a plurality of staples, wherein said staples are removably positioned in said staple cavities; and
a knife member movable toward said distal end, wherein said knife member comprises:
a cutting portion;
a first foot configured to engage said first jaw;
a second foot configured to engage said second jaw;
a first metallic surface;
a first pad attached to said first metallic surface, wherein said first pad is comprised of a resilient material;
a second metallic surface; and
a second pad attached to said second metallic surface, wherein said second pad is comprised of said resilient material, and wherein said first pad and said second pad are configured to facilitate the closing of said pair of jaws.
3. An end effector, comprising:
a first jaw;
a second jaw, wherein one of said first jaw and said second jaw is movable between an open position and closed positions relative to the other of said first jaw and said second jaw;
a plurality of staple cavities;
a plurality of staples, wherein said staples are removably positioned in said staple cavities; and
a translatable firing member, wherein said firing member comprises:
a first portion configured to engage said first jaw, wherein said first portion is comprised of a metal;
a second portion configured to engage said second jaw; and
an attachment configured to contact one of said first jaw and said second jaw, wherein said attachment is comprised of a resilient material.
