FASTENER CARTRIDGE COMPRISING A FIRING MEMBER INCLUDING FASTENER TRANSFER SURFACES
First Claim
1. A fastener cartridge for use with a surgical fastening instrument, wherein said fastening instrument comprises an anvil, and wherein said fastener cartridge comprises:
- a cartridge body, comprising;
a deck including a tissue supporting surface;
a plurality of fastener cavities, wherein each said fastener cavity includes an opening in said tissue supporting surface;
a longitudinal row of fasteners; and
a sled movable between an unfired position and a fired position to lift said fasteners toward the anvil, wherein said sled comprises a first ramp portion configured to lift each said fastener between an unlifted position and a partially lifted position, wherein said sled comprises a second ramp portion configured to lift each said fastener between said partially lifted position and a fully lifted position, and wherein said second ramp portion is positioned laterally and parallel with respect to said first ramp portion.

Abstract
A fastener cartridge can comprise a cartridge body including a plurality of fastener cavities and a plurality of fasteners removably stored therein. The fastener cartridge can further comprise a firing member including a first ramp surface and a second ramp surface which can be configured to co-operatively lift and eject the fasteners from the fastener cavities. The first ramp surface can initially lift the fasteners. The second ramp surface can then complete the lift of the fasteners. In such circumstances, the fasteners can be transferred from the first ramp surface to the second ramp surface of the firing member. In various circumstances, the first ramp surface and/or the second ramp surface can directly engage the fasteners. In other circumstances, the fastener cartridge can include fastener drivers which are directly lifted by the first ramp surface and/or the second ramp surface. The fastener cartridge can further include an anvil.
