CPC A61F 9/00745 (2013.01) | 3 Claims |
1. A phacoemulsification transducer assembly comprising:
a reflector;
a driver connected to the reflector, the driver having a known driver vibration frequency range;
a horn connected to the driver opposite the reflector;
a needle connected to the horn opposite the driver, the needle having a known free shaft length; and
wherein to maximize a desired stroke length of the needle for a minimal amount of power applied to the driver, a material forming the needle is chosen such that a speed of sound through the material results in a quarter-wavelength distance at the driver vibration frequency range substantially equal to the needle free shaft length.
