More Information
Summary:An ultrasonic instrument for use during a surgical procedure includes a body, a shaft assembly, an ultrasonic blade, and an actuation assembly. The body is configured to receive an ultrasonic transducer for selectively generating an oscillation at a first or a second predetermined power level. The shaft assembly projects from the body and includes an acoustic waveguide connected to the ultrasonic blade. The actuation assembly includes a selector collar generally surrounding the body and a plurality of activation buttons disposed radially about the body proximate to the selector collar. The selector collar is selectively movable along the body between a first position and a second position for selecting between the first and second predetermined power levels. The plurality of activation buttons are configured to direct the ultrasonic blade to oscillate with the selected first or second predetermined power levels.
