Abstract
Abstract A surgical ultrasonic horn used in a surgical operation comprises a horn body and an end plate portion. Cutting portions are provided on an edge and an end of the end portion. A passage for irrigation solution extends in the horn body and the end plate portion. At least one bore opens at the cutting portions by a jet angle of 5° to 90° in respect of a plane of the end plate portion. The irrigation solution passage communicates with the bore, thereby the irrigation solution is sprayed therethrough.
