Claim:
1. An apparatus, comprising: (a) a body; (b) a shaft assembly extending distally from the body; (c) an end effector assembly positioned at a distal end of the shaft assembly, wherein the end effector assembly is operable to perform a surgical procedure; and (d) a drive assembly comprising: wherein the drive assembly is operable to convert a single rotary input into at least two rotary outputs, wherein the drive assembly is operable to selectively drive each of the at least two rotary outputs via the at least one rotary cam, wherein the drive assembly is further operable to selectively hold at least one of the outputs stationary while rotating at least one of the other outputs via the at least one rotary cam, wherein the shaft assembly is operable to communicate rotation from the at least two rotary outputs to the end effector assembly, wherein the first, second, and third output shafts are in communication with the end effector via the shaft assembly, wherein the drive assembly is operable to selectively rotate or hold the first, second, and third output shafts in a predetermined sequence in response to rotation of the input shaft in a first input rotation direction, wherein the first output shaft is operable to rotate in a first output rotation direction and then in a second output rotation direction in response to continued rotation of the input shaft in the first input rotation direction, wherein the first output rotation direction and the second output rotation direction are opposite.
