Abstract:
1. An ultrasonic horn configured for use with a surgical ultrasonic handpiece having a resonator, the ultrasonic horn configured to receive ultrasonic energy and conduct the received ultrasonic energy along its length, the ultrasonic horn 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, wherein the elongated member is formed of a rigid ultrasonic energy conductive material selected such that the elongated member conducts ultrasonic energy from its proximal end to its distal end; an extension member being formed of a rigid ultrasonic energy conductive material and connected to the proximal end of the elongated member by a flared member, the extension member having a proximal end and a longitudinal centerline that is an extension of the elongated member centerline; an adapter being formed of a rigid ultrasonic energy conductive material and disposed on the proximal end of the extension member and having a proximal end configured to couple with a resonator, and having a longitudinal centerline that is an extension of and parallel with the elongated member centerline; and a continuous internal channel longitudinally disposed within all of the elongated member, the flared member, the extension member, and the adapter, wherein the internal longitudinal channel comprises the first, second, third, fourth, and fifth internal channels and is configured to form a hollow length extending from the proximal end of the adapter to the generally planar distal end of the elongated member.
