Abstract

A staple cartridge for use with a surgical instrument is disclosed. The staple cartridge comprises a cartridge body comprising a tissue support surface, staple cavities defined within the cartridge body, staples removably positioned in the staple cavities, and a staple driver movably positioned within the staple cavities, wherein the staple driver is configured to support the staples. The staple cartridge further comprises a wedge sled translatable between a proximal end and a distal end of the staple cartridge, wherein the wedge sled is configured to move the staple driver from an unfired position to a fired position during a staple firing stroke, and a driver retention member configured to retain the staple driver in a retention position that allows the wedge sled to be retracted after the staple firing stroke.
