Abstract

See full text

A surgical needle assembly for attachment to an ultrasonic handpiece includes an elongated metal cannula having a distal end and a proximal end. A hub is insert molded onto the cannula generally towards the cannula proximal end and formed from a material having an ultimate strength at least twice a peak cyclical stress force at a joint between the elongated metal cannula and the hub when the surgical needle assembly is in use with the ultrasonic handpiece. The hub material has a stiffness sufficient to limit a motion of the elongated metal cannula to less than 1.5 times an expected peak to peak stroke length when the surgical needle assembly is in use with the ultrasonic handpiece. The hub includes structure for mating attachment to the ultrasonic handpiece.
