The present invention is an ultrasonic surgical instrument having an altered cross sectional area and/or stiffness of 1/2 wave segments of a
waveguide (20) and/or end effector. The waveguide is coupled to an ultrasonic transducer. The 1/2 wave segments of the waveguide or
end effector comprise a number of geometries and function to extend or decrease the length of a waveguide and/or end effector without
adding or removing wave segments. The present invention is intended to function with conventional ultrasonic transducers at
conventional frequencies.
