Classification: CPC A | IPC A

Claim 10:
11. A surgical stapling assembly, comprising:
a motor;
a closure actuator;
a firing actuator;
an end effector, comprising:
a first jaw;
a second jaw movable relative to said first jaw upon actuation of said closure actuator; and

a staple cartridge configured to be removably positioned within said end effector, wherein said staple cartridge comprises:
a firing member movable through a firing stroke upon actuation of said firing actuator;
a plurality of staples removably stored within said staple cartridge, wherein said plurality of staples are configured to be deployed from said staple cartridge upon distal advancement of said firing member; and
an onboard memory configured to store a cartridge identifier, wherein said onboard memory is readable to determine a status of said staple cartridge;

a sensor configured to detect a parameter of said firing member;
a control circuit configured to:
read said onboard memory to determine that said status of said staple cartridge is unspent;

identify said cartridge identifier;
monitor an output of said sensor to detect said distal advancement of said firing member from an unfired position;
transition said status of said staple cartridge from unspent to spent based on the detection of said distal advancement of said firing member from said unfired position;
determine the output of said sensor independently of said onboard memory; and
control a state of the motor based on the identified cartridge identifier, the determined output of said sensor, and the determined status of said staple cartridge.
