Physics of ultrasonic surgery using tissue fragmentation

The mechanism of interaction for the ultrasonic surgical aspirator is poorly understood. A model for the primary mechanism for tissue fragmentation is presented. This involves the horn-tip impact and other mechanical forces, operating in combination with hydrodynamic forces applied to the tissue on...

Summary:The mechanism of interaction for the ultrasonic surgical aspirator is poorly understood. A model for the primary mechanism for tissue fragmentation is presented. This involves the horn-tip impact and other mechanical forces, operating in combination with hydrodynamic forces applied to the tissue on the forward stroke in each cycle. No evidence of cavitation in tissue was observed.
