Classification: CPC A  B | IPC A  B

Claim 8:
9. A surgical instrument for use with a robotic system, the surgical instrument comprising:
a mounting portion coupleable to the robotic system, the mounting portion comprising:
a housing;
a first rotatable drive that transmits a first rotary output motion from the robotic system;
a second rotatable drive that transmits a second rotary output motion from the robotic system; and
a third rotatable drive that transmits a third rotary output motion from the robotic system;

a shaft comprising a longitudinal axis, wherein the shaft is rotatable about the longitudinal axis;
a pivotable section;
an end effector pivotable relative to the longitudinal axis about the pivotable section, wherein the end effector comprises:
a first jaw;
a second jaw rotatable relative to the first jaw; and
a translatable firing driver, comprising:
a proximal end;
a first lateral flange;
a second lateral flange that engages the second jaw in response to the second rotary output motion to hold the second jaw relative to the first jaw; and
a third lateral flange intermediate the first lateral flange and the second lateral flange;

at least one gear-driven portion that is in operable communication with the end effector;
a drive bar comprising a distal end and a flexible portion, wherein the distal end of the drive bar is connected to the proximal end of the translatable firing member to apply a force to the proximal end of the translatable firing driver to push the translatable firing driver distally in response to the second rotary output motion, and wherein the drive bar extends through the pivotable section; and
a translatable articulation member that pivots the end effector about the pivotable section in response to the third rotary output motion.
