ABSTRACT:
An ultrasonic cutting device includes a transducer, an ultrasonic horn and a cutting blade. The transducer generates ultrasonic vibrations in a direction having a longitudinal axis, and the ultrasonic horn has a nodal point and at least three projections extending, respectively, to vibrating faces equidistantly away from and symmetrically about the nodal point, one of the vibrating faces being connected to the transducer so that, in operation, the ultrasonic horn is vibrated. The cutting blade is connected to one of the vibrating faces of the ultrasonic horn which is not connected to the transducer and is positioned in a plane transverse to the longitudinal axis of vibrations so that, in operation, the blade is vibrated.
