Abstract
An ultrasonic resonant vibrator has a connecting portion connecting an ultrasonic vibration transducer to a tool which thereby ultrasonically vibrates at one end for fragmenting contacted tissue. The connecting portion is bifurcated by a slot, and a mount for mounting the vibrator in the handpiece is positioned toward the transducer from the slot. This structure is shaped, dimensioned and made of materials having acoustic properties such that there is only one node of ultrasonic vibrational movement between and including the slot and the mount and this node is spaced from the mount toward the slot to obtain increased ultrasonic vibration at the tissue-contacting end of the tool for better fragmenting a wider variety of tissues.
