Abstract:
An ultrasonic medical device comprising:an ultrasonic generator for producing an ultrasonic vibration in a direction along a longitudinal axis of the ultrasonic generator; an ultrasonic coupling horn; at least one transformer section ultrasonically coupled to the ultrasonic source by the ultrasonic coupling horn, the transformer section modifying the amplitude of the ultrasonic vibration; and a flexible member driven by the transformer section wherein the flexible member has a degree of stiffness which allows the flexible member to support a transverse ultrasonic vibration, wherein the transverse ultrasonic vibration along a length of the flexible member produces a plurality of transverse nodes and anti-nodes along the length of the flexible member wherein at least a portion of the length of the flexible member is used in a medical procedure, wherein more than one of the plurality of transverse anti-nodes are in communication with a biological material.
