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.
Claims20
An ultrasonic horn configured for use with a surgical ultrasonic handpiece having a resonator that generates ultrasonic waves, comprising:
- a tapered elongated member having a proximal end, a distal end, an intermediate point, and a central longitudinal axis;
- an adapter disposed on the proximal end;
- a tip lead configured on the distal end of the elongated member, the tip lead being adapted for cutting hard tissue and having a chisel and awl shaped distal end having a chisel angle that is bisected by the central longitudinal axis of the elongated member, and further having blunt edges, a first planar surface, an opposing second surface;
- and
- an internal channel longitudinally disposed within the elongated member and the adapter, the internal channel forming a hollow length extending from the intermediate point in the elongated member to the proximal end of the elongated member, and the internal channel further extending through the adapter.

- and
- a tip lead configured on the distal end of the elongated member, the tip lead being adapted for cutting hard tissue and having blunt edges, a generally blunt distal tip, a first planar surface having an abrasive mill-file configuration, and an opposing second surface that follows the contour of a solid portion of the elongated member extending distally from the internal channel.
