Abstract
An ultrasonic surgical instrument that has a disposable piezoelectric driver. The surgical instrument includes an ultrasonic horn that is attached to an outer handle. A surgical tip or blade is attached to the proximal end of the horn. The piezoelectric driver is attached to the distal end of the horn. The driver contains at least one piezoelectric transducer which creates a vibratory movement of the horn and the surgical tip. The piezoelectric driver and ultrasonic horn are attached by corresponding threaded members or other means for mechanically coupling the devices so that the driver can be detached from the horn. The piezoelectric driver is disconnected from the horn after use in a surgical procedure. The horn and handle are then sterilized. A new piezoelectric driver is then attached to the horn for use in another procedure.
