A surgical apparatus comprises a body, a shaft assembly, and an end effector. The end effector comprises a clamp arm and an ultrasonic blade in acoustic communication with an ultrasonic transducer via an acoustic waveguide that extends through the shaft assembly. The clamp arm is configured to pivot about a first pivot point toward and away from the ultrasonic blade along a first angular path from a first position to a second position to thereby provide a tissue sealing mode of operation. The clamp arm is further configured to pivot about a second pivot point toward and away from the ultrasonic blade along second angular path from the second position to a third position to thereby provide a tissue cutting and sealing mode of operation. The second pivot point is proximal to the first pivot point.
