Abstract

Surgical instrument systems comprising lockouts are disclosed. The systems comprise a firing member, a staple cartridge assembly, and a lockout member. The lockout member, movable between an unlocked position and a locked position, is configured to prevent the firing member from being advanced through the staple cartridge assembly when the lockout member is in its locked position.
