1. A surgical instrument, comprising:

  • an end effector, comprising;

    an elongated channel configured to operably support a staple cartridge therein;

    an anvil movably supported relative to said elongated channel and being movable to an open position relative to a staple cartridge positioned within said elongated channel upon the application of an opening motion to said anvil, said anvil being movable to a closed position relative to the staple cartridge upon the application of a closing motion to said anvil; and

    a tissue cutting implement movable relative to said elongated channel;

    a shaft assembly connected to said end effector, said shaft assembly comprising a drive shaft operably interfacing with said tissue cutting implement for transmitting motion to said tissue cutting implement;

    a gear drive train operably interfacing with said drive shaft;

    a motor for actuating said gear drive train;

    controlling means for controlling said motor; and

    communicating means for communicating resistive forces experienced by said tissue cutting implement to said controlling means as said tissue cutting implement is driven through tissue clamped between the staple cartridge and said anvil.
