Abstract:
An ultrasonic horn for use with an ultrasonic surgical hand piece including a resonator comprises a contacting annulus having a plurality of angled lands. The lands are alternated around the annulus such that adjacent lands have opposite angles. As a result of the adjacent angled lands, a shear stress field is developed in contacted tissue due to the promotion of refracted longitudinal ultrasonic waves propagating in different directions at the interface to the coupled tissue. The shear stress field enhances the fragmentation and removal rate of fibrous, elastic, and tenacious tissue. The horn is hollow permitting suction to be applied to the tissue for controlling tissue contact with the lands.

US Classification:
606169
Abstract:
Ultrasonic horns configured for use with a surgical ultrasonic handpiece including a resonator are described. The ultrasonic horns include an elongated member having a longitudinal internal channel extending therethrough. Disposed on the distal end of the elongated member is a tip lead configured for cutting and/or abrading hard tissue, for example bone. The tip lead includes an abrasive surface.

US Classification:
600459000
Abstract:
Ultrasonic horns configured for use with a surgical ultrasonic handpiece including a resonator are described. The ultrasonic horns include an elongated member having a longitudinal internal channel extending partially therethrough. Disposed on the distal end of the elongated member is a chisel and awl shaped tip configured for cutting and/or abrading hard tissue, for example bone.
