Summary: | A surgical instrument includes a transducer configured to produce vibrations at a predetermined frequency. The transducer is configured to produce vibrations along a longitudinal axis at a predetermined frequency. An ultrasonic blade extends along the longitudinal axis and is coupled to the transducer. The ultrasonic blade includes a body having a proximal end and a distal end. The distal end is movable relative to the longitudinal axis by the vibrations produced by the transducer. The body includes a treatment region that extends from the proximal end to the distal end. The body includes a tapered concave surface which extends inwardly into the body defining a variety of shapes including a conical shape, a frusto-conical shape, or a partial spheroid. The body includes surface coatings to prevent the formation of a thin layer of fluid on the body which may be atomized thus creating a mist. |
