Abstract
A surgical instrument comprising tissue stops is disclosed.
Claims19
A surgical stapling instrument, comprising:
- a cartridge jaw, comprising:
- a cartridge tissue compression surface;
- a first lateral cartridge side;
- a second lateral cartridge side;
- a first longitudinal row of staple cavities;
- a second longitudinal row of staple cavities;
- staples removably stored in said staple cavities;
- a first cartridge tissue stop extending upwardly from said cartridge tissue compression surface along said first lateral cartridge side;
- a second cartridge tissue stop extending upwardly from said cartridge tissue compression surface along said second lateral cartridge side;
- and
- an anvil jaw rotatable relative to said cartridge jaw between an open position and a fully-clamped position, and wherein said anvil jaw comprises:
- an anvil tissue compression surface;
- longitudinal rows of staple forming pockets that register with said staple cavities when said second jaw is in said fully-clamped position;
- a first lateral anvil side;
- a second lateral anvil side;
- a first anvil tissue stop extending downwardly relative to said cartridge jaw from said first lateral anvil side, wherein said first anvil tissue stop comprises a first distal edge that extends below said cartridge tissue compression surface when said anvil jaw is in said open position and said fully-clamped position;
- and
- a second anvil tissue stop extending downwardly relative to said cartridge jaw from said second lateral anvil side, wherein said second anvil tissue stop comprises
- a second distal edge that extends below said cartridge tissue compression surface when said anvil jaw is in said open position and said fully-clamped position.
