ULTRASONIC CUTTING TOOL WITH TRANSVERSELY RIBBED BLADE AND JAW MEANS

摘要

The cutting tool is powered by an ultrasonic vibration generator through an elongate waveguide. A blade (1) at a distal end of the waveguide has a face with a series of transversely directed ribs (4), separated by grooves (5). A jaw (3) having a correspondingly transverse ribbed face is controllably moveable into interlocking contact with the ribbed face of the blade.
