Abstract

A phacoemulsification tip having a crimped or swaged distal tip. Swaging of the distal end of a phacoemulsification tip produces more efficient cutting during torsional vibration of the tip by increasing the cutting surface area.

Claims (3)

A phacoemulsification tip, comprising: a tubular shaft having a crimped distal end, the distal end having a plurality of fluted cutting edges, the fluted cutting edges located at a terminal end of the tubular shaft and extending back from the terminal end along the tubular shaft, an exterior surface of the fluted cutting edges exposed along a length of the crimped distal end of the tubular shaft.

2. The phacoemulsification tip of claim 1 wherein the shaft contains an aspiration bypass hole.

3. The phacoemulsification tip of claim 1 wherein the shaft is bent relative to a centerline of the shaft.
