A micro surgical phacoemulsification tip wherein a repetitive pattern is etched into the inner lumen surface of a surgical tip in a controlled pattern such that a resonance condition is created which is in harmonic phase with the frequency of the phacoemulsification energy source, thereby reducing destructive interference waves and creating constructive waves; virtually eliminating instantaneous tip temperature spikes and removing the risk of potential tissue burning. More specifically, the present invention is drawn to phacoemulsification needles having a lumen surface having micro-grooved channels positioned thereon which center harmonic phased ultrasonic generated acoustic wavefront interiorly from the needle wall. The micro-grooved channeling of the present invention will work with the axial length of any phacoemulsification needle tip harmonic. |
