An apparatus includes an end effector, a shaft assembly extending proximally from the end effector, an instrument base, and a knife driving assembly. The end effector includes a pair of jaws and a knife member capable of actuating between a proximal and distal position. The knife driving assembly can actuate the knife member between the proximal and distal position. The knife driving assembly includes a cable and a knife drive input assembly coupled only to a first drive input. The knife driven assembly is capable of rotating in first and second angular directions. The cable terminates into a first end and a second end, which are both attached to the knife drive input assembly. A portion of the cable is attached to the knife member. Rotation of the knife drive input assembly in the first angular direction drives the knife member distally. Rotation of the knife drive input assembly in the second angular direction drives the knife member proximally.
