Surgical instrument
DCFirst Claim
1. A surgical fastening instrument, comprising:
- an end effector cartridge assembly, comprising;
a first jaw;
a second jaw, wherein said first jaw is movable relative to said second jaw between an open position and a closed position; and
a fastener cartridge comprising a plurality of fasteners removably stored therein;
a handle, comprising;
an electric motor;
an actuator configured to operate said electric motor; and
a battery configured to supply power to said electric motor;
a firing member, wherein said electric motor is configured to impart a firing motion to said firing member to eject said fasteners from said fastener cartridge; and
an electronic lockout system configured to ascertain whether said fastener cartridge is present in said end effector, wherein said electronic lockout system is further configured to permit said electric motor to apply said firing motion to said firing member when the presence of said fastener cartridge has been ascertained and to prevent said electric motor from applying said firing motion to said firing member when the presence of said fastener cartridge has not been ascertained.

Abstract
A surgical fastening instrument is disclosed. The instrument comprises an end effector cartridge assembly, a handle, and a firing member, wherein an electric motor is configured to impart a firing motion to the firing member to eject fasteners from a fastener cartridge of the end effector cartridge assembly. The instrument further comprises an electronic lockout system configured to ascertain whether the fastener cartridge is present in the end effector, permit the motor to apply the firing motion to the firing member when the presence of the fastener cartridge has been ascertained, and prevent the motor from applying the firing motion to the firing member when the presence of the fastener cartridge has not been ascertained.
