Claim:
A surgical instrument, comprising: a handle; a firing drive, comprising: a firing trigger operably coupled to said handle, wherein said firing drive is configured to generate a rotary firing motion upon a first actuation of said firing trigger and a rotary retraction motion upon an other actuation of said firing trigger; a first drive member, wherein said firing trigger is selectively engageable with said first drive member; and a second drive member, wherein said firing trigger is selectively engageable with said second drive member; an elongate shaft assembly coupled to said handle, wherein said elongate shaft assembly is operably engaged with said first drive member and said second drive member; and an end effector coupled to said elongate shaft assembly, said end effector comprising: an elongate channel configured to operably support a staple cartridge therein; an anvil movably coupled to said elongate channel; and a cutting member operably supported within said elongate channel, wherein said cutting member is operably engaged with said elongate shaft assembly, wherein, when said firing trigger is engaged with said first drive member, said first actuation advances said cutting member a first distance, wherein, when said firing trigger is engaged with said second drive member, said other actuation retracts said cutting member a second distance, and wherein said second distance is greater than said first distance.
