Abstract

An ultrasonic instrument includes a body, a shaft assembly, and an end effector. The shaft assembly extends distally from the body. The shaft assembly includes an acoustic waveguide configured to acoustically couple with an ultrasonic transducer. The end effector includes an ultrasonic blade, a clamp arm and a clamp pad. The ultrasonic blade is in acoustic communication with the waveguide. The clamp arm is pivotally coupled with the shaft assembly. The clamp pad is configured to removably couple with the clamp arm while the clamp arm is pivotally coupled to the shaft assembly.
