A surgical ultrasonic horn (1) used in a surgical operation comprises a horn body (11) and an end plate portion (12). Cutting portions (121) are provided on an edge and an end of the end portion. A passage (21) for irrigation solution extends in the horn body and the end plate portion. At least one bore (124) opens at the cutting portions by a jet angle ( beta ) of 5 DEG to 90 DEG 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. <IMAGE> |
