Summary: | An ultrasonic tip for use with a surgical handpiece to produce both longitudinal and torsional motion. The ultrasonic tip comprises a shaft having a longitudinal axis extending between proximal and distal ends having respective first and second diameters with the first diameter greater than the second diameter. The ultrasonic tip also comprises a cutting feature coupled to the distal end of the shaft. The shaft defines an aspiration lumen that extends along the longitudinal axis of the shaft. A protrusion on the shaft is positioned between the distal end and the proximal end of the shaft. A portion of the protrusion having a third diameter, and the third diameter is less than the first diameter and the third diameter is greater than the second diameter. An aperture is defined by the protrusion and in fluid communication with the aspiration lumen, and the protrusion reinforces an area surrounding the aperture.
