Abstract:
1. A cutting tip and a phacoemulsification surgical handpiece, comprising: a phacoemulsification surgical handpiece comprising a horn configured to torsionally vibrate a cutting tip at a rate of approximately 10 to 60 kHz; and a cutting tip comprising: wherein the proximal portion of the cutting tip length is constrained by the horn of the surgical handpiece such that the shaft centerline of the proximal portion is aligned with an axis of rotation of the horn; wherein the first portion of the cutting tip is straight with a length of approximately 1 7/32 inches and wherein the distal portion extends approximately 5/32 inches below the first portion; wherein the first portion, second portion, third portion and distal end are comprised in a single piece; wherein the second portion, third portion, and distal end together have an axis of rotation relative to the shaft that is substantially aligned with an extended shaft centerline when the proximal portion of the cutting tip length is torsionally vibrated by the phacoemusification surgical handpiece at the rate of approximately 10 to 60 kHz, on an arc with an axis of rotation that is aligned with the shaft centerline at the proximal portion; wherein the distal end is entirely on one side of the extended shaft centerline and at least a portion of a length of the hook is entirely on an opposing side of the centerline.
