1. An ultrasonic surgical instrument, comprising:
(a) an ultrasonic assembly comprising:
(i) a body defining an arcuate channel,
(ii) an acoustic waveguide secured relative to the body and extending along a longitudinal axis, and
(iii) an ultrasonic blade extending distally from the acoustic waveguide; and
(b) a clamp arm assembly coupled to the ultrasonic assembly and at least partially positioned along the longitudinal axis, wherein the clamp arm assembly comprises:
(i) a clamp arm,
(ii) a clamp arm actuator having a protrusion located thereon, and
(iii) a linkage assembly, wherein the linkage assembly is configured to pivotally couple the clamp arm actuator and the clamp arm relative to the body such that the clamp arm actuator rotates toward and away from the body and the clamp arm rotates toward and away from the ultrasonic blade,
wherein the protrusion is sized to be received by the arcuate channel and the protrusion configured to prevent translation of the clamp arm relative to the ultrasonic assembly when the protrusion is received by the arcuate channel.
