In one general aspect, various embodiments are directed to an ultrasonic surgical instrument that comprises a transducer configured to produce a standing wave of vibrations along a longitudinal axis having a node and an anti-node at a predetermined frequency. In various embodiments, an ultrasonic blade extends along the longitudinal axis and is coupled to the transducer. In various embodiments, the ultrasonic blade includes a body having a proximal end and a distal end, wherein the distal end is movable relative to the longitudinal axis by the vibrations produced by the transducer. In one general aspect, various embodiments are directed to a method of assembling the transducer for the ultrasonic surgical instrument. In various embodiments, the method comprises selecting piezoelectric elements and arranging the piezoelectric elements relative to the node to minimize the difference in magnitude between the currents drawn by the piezoelectric elements.
A method of assembling a transducer for a surgical instrument, wherein said transducer is configured to produce a standing wave of vibrations having a node and an anti-node, said method comprising the steps of:
