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.

An ultrasonic horn configured for use with a surgical ultrasonic handpiece having a resonator comprising:
- an elongated member having a longitudinal centerline, a proximal end, a distal end, a first intermediate point disposed between the proximal end of the elongated member and the distal end of the elongated member, a second intermediate point disposed between the first intermediate point and the distal end of the elongated member;
- a third intermediate point disposed between the second intermediate point and the distal end of the elongated member, and a fourth intermediate point disposed between the third intermediate point and the distal end of the elongated member;
- a first hollow portion disposed in the elongated member, having a Gaussian profile extending from the proximal end of the elongated member to the first intermediate point of the elongated member;
- a second hollow portion disposed in the elongated member, having a straight profile extending from the first intermediate point to the second intermediate point;
- a third hollow portion disposed in the elongated member, having a flared exponential profile extending from the second intermediate point to the third intermediate point;
- a fourth hollow portion disposed in the elongated member, having an inverse conical profile extending from the third intermediate point to the fourth intermediate point;
- a fifth hollow portion disposed in the elongated member, having a tapering profile extending from the fourth intermediate point to the distal end of the elongated member;
- a tip lead configured on the distal end of the elongated member, the tip lead including the fourth hollow portion and the fifth hollow portion, a generally planar distal end, and an exterior surface, wherein at least a portion of the exterior surface includes an abrasive structure;
- an extension member connected to the proximal end of the elongated member by a flared member;
- an adapter disposed on the proximal end of the extension member;
- and
- an internal channel longitudinally disposed within the elongated member, the extension member, and the adapter, the internal channel forming a hollow length extending from the proximal end of the elongated member to the generally planar distal end of the elongated member, and the internal channel further extending through the extension member and the adapter, terminating before the resonator.
