Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Field of Application> The present invention relates to a molar tooth cleaning tool that can be used continuously for consumer use, dental care, and veterinary use.

<Prior art> In STJ cleaning, conventionally, the sliding force of the bristles of a toothbrush or the combination of this with an abrasive material such as toothpaste,
Dental plaque, tartar, etc. were removed.

However, with the conventional method, the cleaning of the interdental area and the southern folds of the sliding surface, where the flocked body cannot come into contact, is insufficient.
It has the disadvantage that it cannot completely prevent cavities and remove plaque and tartar.

OBJECT AND STRUCTURE OF THE INVENTION The present invention was provided in order to eliminate the above-mentioned drawbacks, and its purpose is to irradiate the tooth surface and the details between the tooth rows by irradiating the laser beam 1. The purpose is to photodecompose plaque, tartar, and food residue, weakening their adhesion to the tooth surface and promoting their disintegration and fragmentation. Accordingly, the purpose of the present invention is 1-1.
A base member formed to be able to cover two and/or side surfaces of the tooth, a light guiding material having a light output portion facing at least a part of the face facing the Nichinan side of the base member, and a light guiding material that is built in the base member. Alternatively, the present invention can be achieved by a one-tooth cleaning tool comprising an optically connected laser element and a power supply circuit for the laser collector, and is provided so as to be able to emit a laser beam from the light guiding material.

(2) Preferably, the member (2) is made of an elastic material so that it can be fitted into the tooth row.

In this embodiment, when a voltage is applied to the laser element (5), the laser beam emitted from the light emitting part (5a) enters the end face of the light guide part (4), is guided inside the light guide part (4), and passes through. and passes through the fiber material (3) to the side wall portion (4a).
(4b) and is injected into the groove (2a) from the concave bottom (4C).

As shown in FIG. 2, the side wall portion (4a) of the base member (2)
) Cover and attach the base member (2) to the "1 tooth (9) so that (4b) faces the front and back sides of Nichinan (8), turn on the switch actuator (8), and turn on the laser beam. When the laser beam is emitted from the side walls (4a) (4b) and the concave bottom (4c), the laser beam hits the side surface (9a) and side surface (8b) of the tooth.
), the upper surface (9c) and/or between the mouth and mouth to photodecompose dental plaque, tartar, etc., and further sterilize various germs.

Note that since the laser beam may irradiate the gums and oral cavity, the intensity and wavelength of the laser beam should be adjusted to an extent that does not cause damage to the living body.

In addition, the base member (2), the fiber material (3) and the light guide part (
The material for the side walls (4a) (4b) should be heat-resistant and water-resistant, for example, made of heat-resistant plastic.
Making the concave bottom (4C) waterproof is an embodiment included in the present invention.

) is a reflective member fixed to the

The reflective member (21) is made of, for example, aluminum film stretched [“
The aluminum layer may be formed by evaporation or plating.

(21a) is a diffused reflection surface of the reflecting member (21), which is formed into a randomly uneven surface.

This uneven surface may be provided on the reflective member (21) in advance,
After forming the outer surfaces of the outer wall portions (2b) (2c) and the outer bottom portion (2d) into finely rough surfaces by oxidation treatment or the like, a reflective surface may be formed by the above-mentioned vapor deposition or plating process.

(22) is the side wall part (4a) (4b) and the concave bottom part (4C
), and has many small holes (-22a
) is provided.

The reflecting member (22) is also provided with a diffused reflection surface,
The method for forming these is the same as described above.

(23) is a base member (2) facing the tip of the light guiding part (4).
) is a substantially conical reflecting member provided near the concave bottom (4c).

In this embodiment, when a voltage is applied to the laser element (5), the laser beam emitted from the light emitting part (5a) enters the end face of the light guide part (4), is guided inside the light guide part (4), and passes through. The light enters the base member (2), is dispersed and reflected in all directions by the reflective member (23), and is reflected by the reflective member (2+) (22
) and is dispersed through a large number of small holes (22a) and ejected into the groove (2a).

(23a) is a diffused reflection surface formed on the surface of the reflection member (23).

The forming force of the reflecting member (23) and the diffusely reflecting surface (23a) is the same as that of the reflecting member (21) and the diffusely reflecting surface (21a). Cleaning of the air can be carried out.

(51) and (52) are two linear polarizing plates provided as a light amount adjustment mechanism, and are located between the light emitting part (5a) and the light guide part (0) facing the light emitting part (5a) of the laser element. It is arranged.

When a voltage is applied to the laser element (5), the light emitting part (5)
The laser beam (RO) from a) passes through the first linear polarizer (
51), but if the transmission axis of the second polarizing plate (52) is perpendicular to the transmission axis of the first polarizing plate (51) as shown in FIG. (R1) cannot pass through this. Next, when the second linearly polarizing plate (52) is rotated in the direction of the arrow (m) using the knob (52a), the beam transmitted through the second linearly polarizing plate (52) changes as the intersection angle between the transmission axes decreases. The light amount of beam (R2) gradually increases, and when the intersection angle is O'' or 180'', the light amounts of beams (R1) and (R2) become equal.

The beam (R2) passes through the light guiding part (4) and is diffusely reflected by the reflecting members (23) (21) (22), and the diffusely reflected beam is reflected by the side walls (4a) (4b) and the concave bottom (4c). ejected from.
