An ultrasonic tip and methods of operating the same. The ultrasonic tip comprises a shaft including a base and a flexible body. The body comprises a first portion and a second portion. The body is coupled to the base at the first portion and extends from the first portion to the second portion along a longitudinal axis. The second portion includes a cutting portion comprising a neck, and a head extending radially from the longitudinal axis. The head is coupled to the neck. A circular aperture is disposed between the head and the neck to define an inner circumferential surface. The head and the neck form an outer circumferential surface comprising a plurality of cutting teeth, the outer circumferential surface having a first thickness at the head that is greater than a second thickness at the neck.

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.

The present disclosure relates to an ultrasonic surgical handpiece assembly comprising a surgical handpiece for use with an irrigation sleeve and ultrasonic tip. The surgical handpiece may comprise a piezoelectric transducer disposed within a housing and configured to manipulate the ultrasonic tip. One or more lumens and/or a flex circuit including an antenna may be disposed within the surgical handpiece housing. The lumen(s) may be configured to provide irrigation and/or aspiration to the irrigation sleeve and/or ultrasonic tip. The irrigation sleeve may comprise a second antenna configured to communicate with the ultrasonic handpiece antenna. The irrigation sleeve may further comprise and an alignment and/or coupling feature configured to removably secure the irrigation sleeve to the housing and orient the second antenna relative to the ultrasonic handpiece antenna. The irrigation sleeve may further comprise a lumen for supplying irrigation and/or aspiration to the ultrasonic tip.
