Abstract

An end effector can comprise, one, a fastener cartridge including a plurality of fasteners stored therein and, two, an anvil configured to deform the fasteners. The anvil can further comprise extensions extending therefrom which can control the flow of tissue relative to the fastener cartridge and/or support the fasteners as they are ejected from the fastener cartridge. The extensions can having different sizes and/or configurations.

Claims

1. An end effector, comprising:

a first jaw comprising a fastener cartridge, wherein said fastener cartridge comprises;

a cartridge body including a deck configured to support tissue;

fastener cavities defined in said cartridge body; and

fasteners removably positioned within said fastener cavities; and

a second jaw comprising an anvil, wherein said anvil comprises;

a tissue supporting surface configured to support tissue;

forming pockets configured to deform said fasteners; and

anvil projections extending from said tissue supporting surface configured to control the flow of tissue relative to said tissue supporting surface and said deck.

2. The end effector of claim 1, wherein said second jaw is rotatably coupled to said first jaw.

3. The end effector of claim 1, wherein said fastener cavities are arranged in a first longitudinal cavity row and a second longitudinal cavity row, wherein said anvil projections are arranged in a first longitudinal anvil row and a second longitudinal anvil row, wherein said first longitudinal anvil row is aligned with said first longitudinal cavity row, and wherein said second longitudinal anvil row is aligned with said second longitudinal cavity row.

4. The end effector of claim 3, wherein said anvil projections in said first longitudinal anvil row are defined by a first height, wherein said anvil projections in said second longitudinal anvil row are defined by a second height, and wherein said first height is different than said second height.

5. The end effector of claim 1, wherein said fastener cartridge further comprises cartridge projections extending from said deck.

6. The end effector of claim 5, wherein said cartridge projections are aligned with said anvil projections.

7. The end effector of claim 1, wherein said anvil projections extend between said fastener cavities.

8. An end effector, comprising:

a first jaw comprising a fastener cartridge, wherein said fastener cartridge comprises;

a cartridge body including a deck configured to support tissue;

fastener cavities defined in said cartridge body; and

fasteners removably positioned within said fastener cavities; and

a second jaw comprising an anvil, wherein said anvil comprises;

a tissue compression surface configured to support tissue;

forming pockets configured to deform said fasteners; and

tissue control means extending from said tissue compression surface for controlling the flow of tissue relative to said tissue compression surface and said deck.

9. The end effector of claim 8, wherein said second jaw is rotatably coupled to said first jaw.

10. The end effector of claim 8, wherein said fastener cavities are arranged in a first longitudinal cavity row and a second longitudinal cavity row, wherein said tissue control means comprises projections arranged in a first longitudinal anvil row and a second longitudinal anvil row, wherein said first longitudinal anvil row is aligned with said first longitudinal cavity row, and wherein said second longitudinal anvil row is aligned with said second longitudinal cavity row.

11.
