Abstract
A disposable aspiration sleeve for use with an ultrasonic handpiece, which ultrasonic handpiece includes an ultrasonic horn wherein the cylindrical aspiration sleeve, which is provided with a vacuum tube coupling nipple, is removably mounted at its base to the handpiece and is provided with a supporting mount or mounts on its interior surface positioned in such a manner that the supportive mount or mounts each touches the horn at a vibratory node, thereby acoustically isolating the interior wall portion of the cylindrical sleeve from the ultrasonic horn or tip member. The addition of an aspiration sleeve with supporting mount or mounts positioned to rest upon the ultrasonic horn at one or more vibrational nodes enables the use of inexpensive plastic for construction, provides the necessary acoustical isolation for maximization of energy transfer to the tip of the ultrasonic horn, prevents transmission of ultrasonic energy from the horn to surrounding tissue, and creates an annular conduit between the sleeve and the horn for tissue aspiration which cannot be occluded by the sleeve touching the ultrasonic horn.
