(57) Abstract Objective By improving the form of the operation tool Tip operationIt to be possible to make the fragmentation power of tool increase, in addition the operation tool Tip?And others by decreasing the generation of cavitation the airThe ultrasonic operation skillful operation tool which can make the generation of the bubble little is offeredru thing is designated as purpose. Constitution The axis of the ultrasonic operation skillful operation tool which displays tubular formHole, inside diameter of Tip opening than inside diameter of axial borehole section largeTry to become. Especially, as shown in drawing 1, the operation tool TipThe end face is formed hierarchically from the opening facing toward inside. maIn order it is, to decrease perpendicular facing of axial direction, the operation tool destal diagonalIt forms.
