もよい。FIG. 1 is a main part configuration diagram for explaining an example in which the ultrasonic cutting tool is cooled and is prevented from falling off when the cutting tool is broken, in which 10 is a cutting tool and 20 is a cutting tool. Is an ultrasonic drive source, and a well-known ultrasonic vibrator is incorporated in the main body 20a of the ultrasonic drive source 20, and the vibration of the ultrasonic vibrator is a horn-like vibration provided at the tip. Transmitted to body 20b. When the cutting tool 10 is used, the cutting tool 10 is screwed to the horn-shaped member 20b of the ultrasonic drive source 20 with, for example, a screw as shown in the drawing. The cutting tool 10 includes a blade portion 1, a main body portion 2, and a screw portion 3 integrated with the main body portion 1, and the screw portion 3 is screwed onto a tip portion of a horn-shaped member 20b of an ultrasonic drive source 20. Connected and used. The blade 1 may be integral with the main body 2 or may be detachable from the main body 2.

がより効率よく冷却される。In order to prevent such a danger, if the flexible member 4 is integrally bonded to the back surface of the blade portion 1 with an adhesive or the like as shown in the figure, the blade portion may break. However, since the broken portion is connected to the main body 2 side through the flexible member 4, there is no concern that the broken portion will fall.
Reference numeral 5 denotes a water supply hole provided coaxially with the center of the screw portion 3. The end of the water supply hole 5 is connected to the ultrasonic drive source 20 when the cutting tool 10 is connected to the ultrasonic drive source 20. It is adapted to coincide with the drain port of a water supply hole (not shown) provided on the side.
This water supply hole 5 is preferably, as shown in FIG.
In the end portion of the main body 2, each drain port is opened to face both side surfaces of the blade portion 1, and during use, the cooling water supplied through the water supply holes 5a, 5b is It is supplied to both side surfaces of 1 to effectively cool the blade portion 1. That is,
The blade 1 heats the blade by friction with the object to be cut during use, and further heats the object to be cut, which not only accelerates damage to the blade, but also adversely affects the object to be cut. In particular, when the ultrasonic cutting tool is used for dental treatment or the like, heating the affected area,
Gives the patient pain. The water supply hole is provided to solve such a problem, but if both side surfaces of the blade portion are cooled as described above, the entire blade portion is cooled more efficiently. .
