1. An ultrasonic surgical instrument having a handpiece operably supporting at least one ultrasonic transducer therein, said surgical instrument comprising:
- a surgical tool having a proximal end with a cavity therein; and
a waveguide protruding distally from the handpiece and interacting with the at least one ultrasonic transducer, said waveguide having a distal end portion sized to be inserted into said cavity in said proximal end of said surgical tool and selectively expanded into an acoustically coupled retaining engagement therewith.

Abstract
An ultrasonic surgical instrument that has a waveguide that protrudes distally from the handpiece and a surgical tool that is configured to be coupled to the waveguide. The waveguide may have a distal end that is sized to be inserted into a cavity in a proximal end of the surgical tool and then selectively expanded to retain the distal end within the cavity to couple the surgical tool to the waveguide.
