1. A surgical instrument, comprising:
(a) a body assembly;
(b) a shaft assembly defining a longitudinal axis and extending distally from the body assembly, wherein the shaft assembly includes:
(i) a proximal end portion, and
(ii) a distal end portion configured to receive an end effector; and
(c) a rotation control assembly connected to the shaft assembly, wherein the rotation control assembly includes:
(i) a rotation control member connected to the shaft assembly and extending along the longitudinal axis, wherein the rotation control member is configured to be selectively rotated about the longitudinal axis and thereby rotate the shaft assembly about the longitudinal axis,
(ii) a rotation lock operatively connected to the shaft assembly and configured to selectively move between a locked rotation state and an unlocked rotation state, wherein the rotation lock is configured to inhibit rotation of the shaft assembly relative to the body assembly in the locked rotation state, and wherein the rotation lock in the unlocked rotation state allows rotation of the shaft assembly relative to the body assembly via the rotation control member, and
(iii) a lock member positioned between the rotation control member and the shaft assembly, wherein the lock member in the locked rotation state engages each of the rotation control member and the body assembly to inhibit rotation of the shaft assembly relative to the body assembly, and wherein the lock member in the unlocked rotation state is disengaged from at least one of the rotation control member and the body assembly to allow rotation of the shaft assembly relative to the body assembly via the rotation control member.
