A surgical instrument includes a transducer configured to produce vibrations at a predetermined frequency. The transducer is configured to produce vibrations 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 surface coatings to prevent the formation of a thin layer of fluid on the body which may be atomized thus creating a mist. The body may also include a bore configured to emit a spray which will also prevent the formation of thin layer of fluid on the body. |
