1. An ultrasonic surgical instrument for delivering energy to tissue, comprising:

  • an introducer;

    first and second elongate jaw elements carried at a distal working end of said introducer; and

    an ultrasonic waveguide reciprocatably coupled to said introducer;

    wherein said waveguide defines receiving channels therein with engagement surfaces that engage cooperating exterior engagement surfaces of said jaw elements to thereby move the jaw elements from a spaced apart position to an approximated position as the waveguide moves from a first retracted position and to a second extended position relative to said introducer.
