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.

[ What is claimed is:] [7.]7. A surgical tip for the emulsification of tissue, for connection to an energy source generating a wavefront, comprising in combination:an elongate hollow member including a wall defining a lumen said elongate hollow member further having a proximal end and an invasive distal end;means for connecting said proximal end of said elongate hollow member in fluid communication with an energy source thereby allowing a wavefront to travel through said lumen; andat least one micro-channel positioned on-said lumen, wherein said micro-channel has a helical pattern.
