め物を充填する。。2. Related Art FIG. 3 is a configuration diagram for explaining an example of a conventional dental treatment instrument. In the figure, 1 is a vibration generating unit that generates vibration such as ultrasonic subsonic, and 2 is a vibration generating unit 1. Removably mounted tip, 3 is a water channel provided along the central axis of the tip, 4 is a blade, 5 is a chuck, 6 is a chuck knob, and 7 and 8 are O-rings, as is well known. 4 is inserted into the chuck 5 from the direction of arrow A using the tapered portion 6a of the chuck knob 6 and positioned to a predetermined length,
The chuck knob 6 is screwed in to fix the blade 4 with the chuck 5, and the O-rings 7 and 8 prevent water from leaking upward. In this way, the blade 4
When the water is supplied to the water channel 3 and the vibration generating element in the vibration generating unit 1 is vibrated after holding the tip of the tip 2, the water in the water channel 3 vibrates and the vibration is transmitted to the blade 4. Since the blade 4 vibrates, the tip of the blade 4 is inserted into the root canal to expand the root canal, and cleaning or filling of the root canal is performed. .

を固定することができる。1. Configuration FIG. 1 is a schematic view of a main part of a dental treatment instrument according to the present invention, more specifically, a sectional view of a tip of a tip, in which 10 is a tip and 11 is a substantially central axis (central axis and center) of the tip 10. A channel (a channel for vibration propagation) provided along an axis (including an axis slightly off the axis), 12 is a blade, 13 is a set screw member,
14 is an O-ring, 15 and 16 are seals, and 11 'is a water channel around the blade (water channel for cleaning). The treatment instrument according to the present invention is different from the prior art shown in FIG. However, the method of using it as a therapeutic device is exactly the same as the conventional therapeutic device shown in FIG. Thus, the tip according to the present invention allows the blade 12 to be inserted into the tip of the tip in the direction orthogonal to the water channel 11 (hence, the blade 12).
And a screw hole extending in the axial direction of the chip, and the set screw member 13 is screwed into the screw hole. Therefore, according to the present invention, when the set screw member 13 is screwed into the through hole at the tip of the chip and the set screw member 13 is screwed, the set screw member 13 can be fixed by hitting the set screw member 13 with the tip thereof.

する。2 (a) to (c) are diagrams showing an outline of a configuration example of a water channel 11 'around each blade 12, and all the drawings show the first example.
The principal part block diagram seen from the II-II line direction of a figure is shown. FIG. 2 (a) corresponds to the embodiment shown in FIG. 1, and in this embodiment, the blade 12 is eccentrically fixed to the tip 10 side with respect to the center of the blade insertion hole and stopped. An example in which a water passage 11 'is provided on the screw side, FIG. 2B shows an example in which a contact member 17 having a recess having the same diameter as the diameter of the blade 12 is provided at the tip of the set screw member 13, Figure (c) shows the waterway 1.
1 shows an example in which the blade insertion hole and the set screw hole are eccentrically formed with respect to 1, and thereby the water channel 1 is formed around the blade 12.
1'is provided so that water propagating through the water channel 11 is discharged from around the blade through the water channel 11 'and used for cleaning.
