A
surgical instrument having a remotely controllable
user interface, and a firing drive configured to generate a rotary firing motion upon a first actuation of the remotely controllable
user interface and a rotary
refraction motion upon an other actuation of remotely controllable
user interface. The instrument includes a first drive member, wherein remotely controllable user interface is selectively engageable with the first drive member, and a second drive member, wherein the remotely controllable user interface is selectively engageable with the second drive member. The instrument also includes an elongate shaft
assembly operably engaged with the first drive member and the second drive member. The instrument further includes an end
effector coupled to the elongate shaft
assembly. The end
effector includes an elongate channel configured to operably support a staple
cartridge therein, and an anvil movably coupled to the elongate channel. The end
effector also includes a
cutting member operably supported within the elongate channel, wherein the
cutting member is operably engaged with the elongate shaft
assembly. The instrument is such that when the remotely controllable user interface operates the first drive member, the first actuation advances the
cutting member a first distance, wherein, when the remotely controllable user interface operates the second drive member, the other actuation retracts the cutting member a second distance, and wherein the second distance is greater than the first distance.
