摘要：
An ultrasonic instrument comprises a handle assembly configured to receive an ultrasonic transducer, a shaft assembly having an acoustic waveguide and an ultrasonic blade, and a retractable clamp arm. The ultrasonic blade is in acoustic communication with the acoustic waveguide such that the ultrasonic transducer is operable to drive the ultrasonic blade to vibrate ultrasonically via the acoustic waveguide. The clamp arm is configured to selectively translate between an inoperative position and an operative position. The clamp arm is positioned generally proximal to the ultrasonic blade when the clamp arm is in the inoperative position. The clamp arm is positioned lateral to the ultrasonic blade when the clamp arm is in the operative position. When in the operative position, the clamp arm is operable to move toward and away from the ultrasonic blade so as to capture and compress tissue between the clamp arm and the ultrasonic blade.
