Description

[Detailed Description of the Invention] Technical Field The present invention relates to a laser beam irradiation chip, and more particularly, to a laser beam irradiation chip that emits laser light into the body to perform treatment.

PRIOR ART Recently, various treatments have been performed by irradiating the affected area with laser light, but when the affected area is inside the body, conventional laser light treatment devices emit laser light from above the skin. Therefore, the laser light could not be sent directly into the body, and the laser light could not reach the affected area sufficiently, making it impossible to sufficiently increase the therapeutic effect.

Purpose This invention was made in view of the above-mentioned circumstances, and in particular, it was made for the purpose of providing a laser beam irradiation chip that can be inserted into the body and directly irradiate the affected part of the body with laser light. It is something that

Configuration FIG. 1 is a side cross-sectional configuration diagram for explaining one embodiment of a laser beam irradiation chip according to the present invention, in which 10 is a laser beam irradiation chip, and 20 is a laser beam irradiation chip 10 that can be freely attached and detached. The hand piece 20 has a built-in semiconductor laser element, and laser light from the semiconductor laser element is transmitted through an optical fiber 21. The laser beam irradiation chip 10 has one end 10a configured to be detachably attached to the hand piece 20.
and a needle-shaped other end 10b formed to be able to be punctured.
It consists of a hollow needle having a hollow part 10c penetrating the inside, and in use, when the laser beam irradiation chip 10 is attached to the handpiece 20 and a semiconductor laser element (not shown) in the handpiece 20 is turned on, the semiconductor laser Laser light from the element is transmitted through the optical fiber 21 and introduced into the hollow portion 10c of the laser light irradiation chip 10, and the laser light is irradiated from the tip of the laser light irradiation chip 10.
In addition, although the example in which a semiconductor laser element is provided in the hand piece 20 and the laser light from the semiconductor laser element is transmitted through the optical fiber 21 has been described above, the laser light from the semiconductor laser element is transmitted through the optical fiber 21. That is directly the optical fiber 2
The optical fiber 21 may be introduced into the hollow part 10c in the laser beam irradiation chip 10 without passing through the optical fiber 21.
The laser beam from the laser beam or the laser beam from the semiconductor laser element is focused by a lens or the like into the hollow portion 10c.
It is easy to understand that it may be introduced internally. In addition, although the case where the semiconductor laser element is built in the hand piece 20 has been described above, it is not necessarily necessary to build the semiconductor laser element into the hand piece, and the laser beam from a separately provided laser beam generator can be used. It will be readily understood that the handpiece may be supplied through an optical fiber or the like.

Therefore, in the present invention, the laser light irradiation chip 10 is configured to be able to irradiate the inside of the body with laser light. Therefore, the laser light irradiation chip 10 is inserted into the affected area and the laser light source is turned on. Then,
Laser light is emitted from the tip of the hollow portion 10c, and the laser light can be directly irradiated onto the affected area within the body.

In FIG. 1, reference numeral 11 is a scale indicating the distance from the tip of the laser beam irradiation tip, and when such a scale is attached to the laser beam irradiation tip 10, it is easy to know the puncture depth of the needle-like member. This makes it possible to irradiate the affected area with laser light more accurately.

Further, if the inner surface of the hollow portion 10c is formed as a light reflecting surface, the laser beam introduced into the hollow portion 10c can be effectively guided to the needle-like tip. It's a good idea to keep it.

Effects As is clear from the above explanation, according to the present invention, it is possible to directly irradiate the affected area within the body with laser light, which can significantly improve the therapeutic effect compared to conventional techniques that irradiate from the outside. . Furthermore, since the laser beam irradiation tip is made detachable from the handpiece, the laser beam irradiation tip can be made disposable, or only the needle-like member needs to be sterilized, making it extremely hygienic. In addition, if the laser beam irradiation tip is marked with a scale indicating the distance from the tip, the tip of the laser beam irradiation tip can be punctured accurately to the depth of the affected area, and the laser beam can be irradiated more accurately to the affected area. There are effects such as being able to.
