Abstract
An ultrasonic transducer assembly of an ultrasonic surgical instrument includes a piezoelectric stack, an ultrasonic horn secured to and extending distally from the piezoelectric stack, and a casing. The ultrasonic horn includes a body and a nose extending distally from the body. The casing is disposed about the piezoelectric stack and the body of the ultrasonic horn. The casing defines a distal opening through which the nose of the ultrasonic horn extends. The casing is hermetically sealed to the ultrasonic horn about the distal opening to define a hermetically sealed interior enclosing the piezoelectric stack and the body of the ultrasonic horn therein.
