    摘要: Probes for delivering ultrasonic energy and related methods. The probe includes a shank having a shaft coupling a proximal end to a distal end. The shank is configured to propagate ultrasonic energy from the proximal end to a tip of the distal end in a propagation direction parallel to a longitudinal axis disposed along a centerline of the shank. The tip may be positioned to substantially coincide with a displacement antinode position when the ultrasonic energy corresponds to odd integer multiples of a quarter wavelength of a resonance frequency. Multiple grooves within the shaft are configured to create multiple cavitation volumes in a medium proximate to the shank responsive to the ultrasonic energy. The multiple grooves include a second groove intervening between a first groove and the proximal end. The first groove is positioned at a distance of an integer multiple of a half-wavelength of the resonance frequency.
