Detailed drawing of the irradiation block in this invention. The fragmentary sectional view of other Examples. FIG. 7 is a partial perspective view of the lamp of FIG. 6. The fragmentary sectional view of the Example by the other lamp structure of FIG.

FIG. 1 is a top view of an organic dental contaminant removal device for an artificial tooth root according to the present invention, and also shows a dental electric drill 31 having a prosthetic tooth root 30 attached to the tip.
FIG. 2 is a cross-sectional view taken along the line XX in FIG. 1, and an excimer lamp 2 is disposed in the casing 1. The excimer lamp 2 has a known shape. In this example, the excimer lamp 2 has a structure in which a pair of external electrodes 2b and 2b are provided on the upper and lower surfaces of a flat discharge vessel 2a.
The top plate 3 of the casing 1 is formed with an opening 4 for emitting radiated light to the outside at a position facing the excimer lamp 2, and the irradiation block 5 is located in the opening 4 and the casing 5 1 is provided so as to be detachable.
The irradiation block 5 is made of an ultraviolet light transmissive material such as quartz glass, and the lower surface thereof, that is, the surface facing the excimer lamp 2 forms the light incident portion 5a, and the upper surface, ie, the surface facing the artificial tooth root 30. Constitutes the light emitting portion 5b.
The irradiation block 5 is placed on the excimer lamp 2 so as to be inserted into the opening 4.
In addition, although the irradiation block 5 shall be directly mounted in the excimer lamp 2, it is not restricted to this, The structure which detachably latches to the top plate 3 of the casing 1 may be sufficient.

The top plate 3 of the casing 1 is provided with a block cover 7 that can be opened and closed so as to cover the irradiation block 5 and the artificial tooth root 30. By this block cover 7, a processed product accommodation portion 8 is formed therein, and an artificial tooth root 30 as a processed product is accommodated therein.
The block cover 7 is preferably made of an ultraviolet light blocking material that blocks at least ultraviolet light from the excimer lamp 2 and is a material that transmits visible light. As such a specific material, for example, an acrylic resin, a cycloolefin copolymer resin, a cycloolefin polymer resin, a polycarbonate resin, or the like can be used.
The UV light blocking ability prevents the doctors and other workers performing artificial tooth cleaning from being irradiated with UV light, and the visible light transmission enables the excimer lamp to be turned on / off. Can be visually confirmed.

In the figure, the block cover 7 is shown as being rotatably provided by a hinge 9, but it may be simply placed on the top 3 from above, in which case An appropriate positioning means such as a stepped portion (not shown) may be provided.
Further, as shown in FIG. 3, the block cover 7 is formed with a notch 7a, and when set so as to cover the irradiation block 5 and the artificial tooth root 30 at the irradiation cleaning position, interference with these blocks will occur. There is nothing to do.
As shown in FIG. 2, a lamp housing portion 11 for housing the excimer lamp 2 is partitioned and formed in the housing 1 by a partition wall 10. An exhaust pipe 12 is connected to the lamp housing portion 11 to exhaust the inside of the lamp housing portion 11.
Reference numeral 14 denotes a power source for the excimer lamp 2.

With reference to FIG. 1, a positioning member 15 of an artificial tooth root 30 is detachably provided in the vicinity of the irradiation block 5 on the top plate 3 of the casing 1, and the artificial tooth root 30 is mounted on the positioning member 15. When the tip 31 a of the electric drill 31 is positioned, the artificial tooth root 30 is positioned at a predetermined position above the irradiation block 5.
More specifically, the mounting tables 16 and 17 for the drill 31 on which the artificial tooth root 30 is similarly mounted on the top plate 3 are detachably provided, and the drill 31 is mounted on the mounting tables 16 and 17. When the distal end portion 31 a is set on the positioning member 15, the artificial tooth root 30 is positioned with respect to the irradiation block 5.

The artificial tooth cleaning operation using the artificial root organic contaminant removal apparatus described above will be described as follows.
Prior to the cleaning process, the irradiation block 5, the positioning member 15, and the mounting tables 16 and 17 are removed from the casing 1, and sterilized by heating or the like in advance. The sterilized irradiation block 5 is inserted into the opening 4 and placed on the excimer lamp 2, and the positioning member 15 and the placement tables 16 and 17 are attached on the top 3.
Next, when the drill 31 to which the artificial dental root 30 to be cleaned is mounted is placed on the mounting tables 16 and 17 and the distal end portion 31 a is set on the positioning member 15, the artificial dental root 30 is set on the irradiation block 5. Is done.
Thereafter, the block cover 7 is closed to surround the artificial tooth root 30 so as to be accommodated in the treatment object accommodating portion 8.

Next, when a fan (not shown) is operated, the gas in the lamp housing portion 11 is exhausted to the outside through the exhaust pipe 12.
Thereafter, when the excimer lamp 2 is turned on by the power source 14, ultraviolet light having a peak wavelength of, for example, 172 nm is emitted from the excimer lamp 2.
The ultraviolet light is incident on the irradiation block 5 from the light incident part 5a, passes through the light, is emitted from the light emitting part 5b, and is irradiated onto the upper artificial tooth root 30. At this time, if the artificial tooth root 30 is rotated at a low speed by the drill 31, the entire circumference is irradiated with ultraviolet light uniformly and cleaned uniformly.

  Further, since the ultraviolet light blocking material of the block cover 7 is made of a visible light transmitting material, visible light from the excimer lamp 2 is emitted to the outside through the block cover 7, so that the lighting state of the excimer lamp 2 is visually observed. Can be confirmed.

When the cleaning of the artificial tooth root 30 is completed, the power supply from the power source 14 is ended, the excimer lamp 2 is turned off, the block cover 7 is opened, and the artificial tooth root 30 is taken out.
When another patient is treated after removing the artificial root, at least the irradiation block 5 that approaches or contacts the artificial root must be sterilized.
At this time, since the irradiation block 5 is detachable from the casing 1, it is easy to attach and detach for sterilization work. Furthermore, when the structure is placed on the excimer lamp 2, the irradiation block 5 is more detachable. It becomes easier. Further, the positions of the excimer lamp 2 and the irradiation block 5 are very close to each other, and the attenuation of the ultraviolet light due to the air (oxygen) therebetween hardly occurs.

In the above embodiment, the excimer lamp 2 is a flat discharge vessel, but is not limited thereto, and may be a cylindrical discharge vessel. FIG. 4 shows this example.
An external electrode 2c is provided on the outer periphery of the cylindrical discharge vessel 2a, and an internal electrode 2d is disposed therein.
The light introducing portion 5a of the irradiation block 5 is recessed on an arc so as to follow the shape of the discharge vessel 2a, and the excimer lamp 2 is disposed in the recessed light introducing portion 5a.

Further, as shown in FIG. 5A, the irradiation block 5 is coated with an ultraviolet light blocking material 20 on the outer surface 5c other than the light incident portion 5a and the light emitting portion 5b of the irradiation block 5. . Thereby, since the ultraviolet light from the excimer lamp 2 is emitted only from the light emitting part 5b, an effective cleaning effect is brought about, and since it is not emitted to other undesired locations, the worker is irradiated with ultraviolet light. It never happens.
Furthermore, you may use what gave the ultraviolet light reflection function to this ultraviolet light shielding material 20, and it can irradiate the artificial tooth root effectively with the ultraviolet light reflected by the ultraviolet light shielding material, The ultraviolet light from the excimer lamp can be used efficiently.
Such an ultraviolet light blocking material 20 can be composed of, for example, a 99.99% aluminum vapor deposition film, and the film thickness in this case is 100 to 150 μm.

  Moreover, as shown to FIG. 5 (B), the recessed part 6 can be formed in the irradiation block 5, and this recessed part 6 can also be made into the light emission part 5b. Also in this case, the ultraviolet light shielding material 20 is coated on the outer surface 5c excluding the concave portion 6 (light emitting portion 5b) and the light incident portion 5a. At the time of cleaning, the artificial tooth root 30 is inserted into the concave portion 6 and irradiated with ultraviolet light from the periphery thereof.

By the way, when the irradiation block 5 is configured to be directly mounted on the excimer lamp 2, when the external electrode is formed by vapor deposition of a conductor, the vapor deposition electrode may be damaged. Is made of, for example, quartz glass or a ceramic material, so that when they come into contact with each other, they may be damaged and often broken.
In order to prevent this, in the example shown in FIGS. 6 and 7, a cushion material is interposed between the two.
6 and 7, the wire 21 is wound around the outer periphery of the discharge vessel 2a of the excimer lamp 2 as a cushion material at a plurality of locations in the longitudinal direction. The wire 21 is made of, for example, stainless steel from the viewpoint of ultraviolet light resistance.
Thereby, it is avoided that ceramics contact | abut directly, The damage can be prevented.
When the external electrode has a wire mesh structure, the external electrode can be used as a cushion material.
Further, FIG. 8 shows a case where the discharge vessel 2a of the excimer lamp 2 has a cylindrical shape, and a wire 21 as a cushioning material is wound around the outer periphery thereof.

As described above, in the organic dental contaminant removal device for an artificial tooth root according to the present invention, the light incident opening facing the excimer lamp and the artificial tooth root are opposed to the light extraction opening of the casing housing the excimer lamp. An irradiation block made of an ultraviolet light transmissive material with a light emitting part is detachably attached, so that the artificial tooth root can be irradiated efficiently with ultraviolet light from an excimer lamp, effectively adhering organic contaminants. It can be removed. Moreover, since the irradiation block is detachable, it can be easily sterilized by removing it from the casing.
In addition, since the ultraviolet light blocking material is coated on the outer surface of the irradiation block other than the light incident portion and the light emitting portion, the ultraviolet light is effectively applied only to the artificial tooth root disposed corresponding to the light emitting portion. While being able to irradiate, workers such as dentists are not irradiated with ultraviolet light.
In addition, since the block cover made of an ultraviolet light blocking material is provided so as to be freely opened and closed, the worker is not irradiated with ultraviolet light from the excimer lamp.
In this way, the present invention is a functional organic contaminant that can achieve a safe, reliable, and easy cleaning treatment of an artificial tooth root with ultraviolet light without irradiating the worker such as a dentist with ultraviolet light. A removal device is realized.
