1. A powered surgical stapler, comprising:
a housing;
a motor-driven input configured to generate a rotary motion;
an actuator movable relative to said housing between an unactuated position and an actuated position;
an elongate shaft extending from said housing;
an end effector extending from said elongate shaft, wherein said end effector comprises a first jaw and a second jaw movable relative to said first jaw between an unclamped state and a clamped state in response to said actuator, and wherein said second jaw is moved from said unclamped state to said clamped state during a closure stroke in response to said actuator moving from said unactuated position toward said actuated position;
a firing driver configured to translate within said end effector during a firing stroke in response to said rotary motion, wherein said firing stroke and said closure stroke are separate and distinct, wherein said firing driver is resettable to translate through another firing stroke, wherein said firing driver comprises a cam, and wherein said cam cammingly engages said second jaw during said firing stroke;
a firing lockout; and
a display which selectively displays:
whether a predetermined amount of time has elapsed after said end effector is transitioned into said clamped state;
the position of said firing driver;
a locked-out status indicative of said firing driver being prevented from performing said firing stroke by said firing lockout; and
the force experienced by said firing driver during said firing stroke.
