Abstract
An ultrasonic surgical handpiece comprising a thermal diffuser that includes a thermal conductive layer and an electrical insulating layer. The thermal diffuser reduces hot spots that are objectionable to the user. The handpiece may also comprise an anti-rotation feature which distributes force of the metal horn applied to the polymer housing by increasing applied area under torque.
