    摘要: A method employing a handpiece having at least one set of piezoelectric elements polarized to produce longitudinal motion when excited at the relevant resonant frequency. The piezoelectric crystals are connected to an ultrasonic horn to which a cutting tip is attached. The horn and/or the cutting tip contains a plurality of diagonal slits or grooves. The slits or grooves produce optimized torsional movement in the cutting tip when the piezoelectric crystals are excited at a second resonant frequency. When in torsional mode, material may clog the cutting tip. The present method includes the step of providing a pulse of longitudinal movement of the tip when clogging is detected.

    摘要: An apparatus and method for the dissociation of soft proteinaceous tissue using pulsed rapid variable direction energy field flow fractionization is disclosed. The pulsed rapid disruptive energy field is created by the use of a probe which surrounds the soft proteinaceous tissue to be removed. Once the adhesive mechanism between tissue constituents has been compromised, fluidic techniques are used to remove the dissociated tissue.
