Surgical stapling instrument comprising multiple lockouts

A surgical stapling instrument, comprising:

• a shaft;
• an articulation joint;
• and
• an end effector assembly, comprising:
• a first jaw;
• a second jaw movable relative to the said first jaw;
• an anvil configured to deform staples;
• a drive system, comprising:
• a rotary input;
• a main drive comprising a first input gear configured to be driven by said rotary input, wherein said main drive is configured to move said second jaw and fire a plurality of staples from a staple cartridge;
• and
• a lockout drive, comprising:
• a second input gear configured to be driven by said rotary input;
• an unlocked configuration when a staple cartridge is installed within said end effector assembly, wherein said lockout drive is configured to permit said main drive to be driven when said lockout drive is in said unlocked configuration;
• and
• a locked configuration when a staple cartridge is not installed within said end effector assembly and said lockout drive prevents said main drive from being driven;
• and
• a second lockout comprising an unlocked configuration when an unfired staple cartridge is installed within said end effector assembly and a locked configuration, wherein, when in said unlocked configuration, said second lockout is configured to permit actuation of said main drive, and wherein, when in said locked configuration, said second lockout is configured to prevent actuation of said main drive.

A surgical stapling attachment configured to be attached to a surgical instrument handle, said surgical stapling attachment comprising:

• an attachment portion;
• a shaft;
• and
• an end effector assembly, comprising:
• an unclamped configuration and a clamped configuration;
• a replaceable staple cartridge comprising a cartridge body and a plurality of staples removably stored within said cartridge body, wherein said replaceable staple cartridge is configured to be installed into said end effector assembly;
• an anvil configured to deform said staples;
• a drive system, comprising:
• a rotary input;
• a main drive in driving engagement with said rotary input, wherein said main drive is configured to approximate said cartridge body and said anvil and fire said staples;
• and
• a lockout drive in driving engagement with said rotary input, wherein said lockout drive is configured to prevent said main drive from being driven when said end effector assembly is in said unclamped configuration and said replaceable staple cartridge is not installed within said end effector assembly;
• and
• a lockout member configured to prevent actuation of said main drive when said end effector assembly is in said unclamped configuration and said replaceable staple cartridge has been fired.
