Ultrasonic surgical handpiece

A surgical instrument comprising:

• an ultrasonic handpiece having an ultrasonic handpiece distal end and an ultrasonic handpiece proximal end;
• a transducer of the ultrasonic handpiece having a transducer distal end and a transducer proximal end;
• an amplifier of the transducer having an amplifier distal end and an amplifier proximal end;
• and
• an ultrasonic tip having an ultrasonic tip distal end, an ultrasonic tip proximal end, an ultrasonic tip overall length, an ultrasonic tip minimum outer diameter, and an ultrasonic tip maximum outer diameter wherein the ultrasonic tip proximal end is connected directly or indirectly to the amplifier distal end and wherein the ultrasonic tip has a maximum oscillation amplitude of greater than about 444.5 micrometers and wherein the ultrasonic handpiece is configured to maintain the maximum oscillation amplitude for at least about 40 seconds.
