Claim 0:
1. A surgical stapling device, comprising:
a surgical end effector, comprising:
a cartridge jaw defining a vertically extending end effector central plane; and
an anvil comprising:
an anvil mounting tab, wherein said anvil mounting tab is positioned only on one lateral side of the vertically extending end effector central plane such that said anvil is pivotally coupled to said cartridge jaw only on the one lateral side of the vertically extending end effector central plane for selective pivotal motion relative to said cartridge jaw between a closed position and an open position, wherein said anvil mounting tab is pivotally coupled to said cartridge jaw about a pivot axis that is transverse to the vertically extending end effector central plane; and
an anvil tail protruding proximally from said anvil mounting tab;

a firing member, wherein said firing member is axially movable within said surgical end effector between a starting position and an ending position;
a rotary firing shaft operably interfacing with said firing member to apply rotary firing motions thereto to drive said firing member between the starting position and the ending position;
a closure linkage operably coupled to said anvil tail, wherein said closure linkage is configured to apply opening motions and closing motions to said anvil tail; and
a rotary closure shaft operably interfacing with said closure linkage to apply rotary closure motions to said closure linkage, wherein said rotary closure shaft is independently rotatable relative to said rotary firing shaft.
