1. A surgical instrument configured for use in connection with a staple cartridge comprising a plurality of surgical staples stored therein and an axially movable camming sled configured to eject the surgical staples therefrom when the axially movable camming sled is moved from a starting position to a fully fired position in the staple cartridge, wherein said surgical instrument comprises:
a surgical end effector, comprising:
a first jaw configured to operably support the staple cartridge therein; and
a second jaw movable between an open position and a closed position relative to said first jaw, and wherein said surgical instrument further comprises:
an axially movable firing member configured to move between a beginning position in said surgical end effector and an ending position in said surgical end effector, wherein said axially movable firing member comprises:
a distal head comprising a top portion, a bottom portion, and a vertically-extending body intermediate the top portion and the bottom portion, wherein the top portion and the bottom portion are integrally formed with the body;
a first flexible drive coil extending proximally from said top portion of said distal head, wherein said first flexible drive coil is to apply top axial drive motions to said distal head; and
a second flexible drive coil extending proximally from said bottom portion of said distal head, wherein said second flexible drive coil is vertically spaced from said first flexible drive coil, and wherein said second flexible drive coil is to apply bottom axial drive motions to the distal head; and
a firing member lock supported in said surgical end effector, wherein said firing member lock is configured to prevent said axially movable firing member from moving distally from the beginning position to the ending position unless the axially movable camming sled in the staple cartridge is in the starting position and in engagement with said firing member lock.
