FIELD: medicine.
SUBSTANCE: invention relates to medical equipment. End effector for use with a surgical instrument includes a first jaw, a second jaw, a blade assembly and a lockout assembly. First jaw is removably coupled with a staple cartridge. Second jaw is movably coupled with the first jaw. Blade assembly translates relative to the first jaw and includes a first tab. Lockout assembly includes a resilient member that biases the blade assembly to a lockout position. Lockout assembly engages the first tab of the blade assembly in the lockout position to prevent the blade assembly from translating distally relative to the first jaw when a staple cartridge is absent from the first jaw or when a spent staple cartridge is disposed in the first jaw.
