１の実施例と同じである。When the affected area is treated by using the ultrasonic treatment apparatus 30, the ultrasonic treatment apparatus 30 is operated as in the first embodiment, but the physiological saline used for cleaning and cooling is supplied to the water supply groove 12. Through the water supply hole 33 from the deformed sheath 31
Water is delivered to the affected area from the tip of. The other operating conditions are the same as in the first embodiment.

を妨げず、摩擦熱は発生しない。Reference numeral 41 in FIG. 10 is a probe, and a sheath 42 is provided so as to cover the periphery of the probe 41. The probe 41 located inside the sheath 42
A pre-suction orifice 43 is provided on the side surface and the water supply port 44 at the distal end of the sheath 42 is covered with an elastic member 45 such as rubber. Although this elastic member 45 is in contact with the probe 41, since it has elasticity, it does not hinder the vibration of the probe 41 and frictional heat is not generated.
