Claim 10:
11. A surgical instrument, comprising:
a shaft;
an end effector extending from said shaft;
a drive electric motor;
a shifter electric motor configurable in a first configuration, a second configuration, and a third configuration;
a first drive system configured to perform a first end effector function, wherein said first end effector function comprises pivoting said end effector relative to said shaft, and wherein said first drive system is drivable by said drive electric motor when said shifter electric motor is in said first configuration;
a second drive system configured to perform a second end effector function, wherein said second end effector function comprises moving said end effector toward a clamped position, and wherein said second drive system is drivable by said drive electric motor when said shifter electric motor is in said second configuration; and
a third drive system configured to perform a third end effector function, wherein said third end effector function comprises performing a firing stroke, and wherein said third drive system is drivable by said drive electric motor when said shifter electric motor is in said third configuration,
wherein said second drive system and said third drive system are not drivable by said drive electric motor when said shifter electric motor is in said first configuration, wherein said first drive system and said third drive system are not drivable by said drive electric motor when said shifter electric motor is in said second configuration, wherein said first drive system and said second drive system are not drivable by said drive electric motor when said shifter electric motor is in said third configuration, wherein said first drive system comprises a first drive shaft, wherein said second drive system comprises a second drive shaft, wherein said third drive system comprises a third drive shaft, wherein said first drive shaft, said second drive shaft, and said third drive shaft are concentrically nested along a longitudinal axis within the shaft, wherein said first drive shaft comprises a first rotatable drive shaft, wherein said second drive shaft comprises a second rotatable drive shaft, and wherein said third drive shaft comprises a third rotatable drive shaft.
