Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laser treatment apparatus, and more particularly to a laser treatment apparatus capable of irradiating laser beams having a plurality of wavelengths simultaneously or individually.

[0002]

2. Description of the Related Art It is well known that various medical treatments are carried out by irradiating a treated area with laser light, and it is also well known that the wavelength of laser light to be irradiated must be changed according to the purpose of treatment. For example, it is well known that the HeNe laser is effective in promoting the healing of wounds, extinguishing inflammation, etc., and the LD (semiconductor laser) is effective in alleviating pain.

[0003]

However, in the conventional laser treatment apparatus, only a laser beam of a single wavelength can be irradiated from a single laser handpiece,
A laser treatment device must be used for each treatment purpose, which is very inconvenient and inconvenient.

[0004]

In order to solve the above-mentioned problems, the present invention introduces (1) a plurality of laser light oscillators for generating laser lights having different wavelengths and laser lights from the respective laser light oscillators. A plurality of optical fibers, and one optical fiber into which laser light from these optical fibers is introduced and a laser handpiece is attached to the light emitting end side, and the light emitting ends of the plurality of optical fibers are bundled. As a bundle end, the diameter of the light-receiving end of the one optical fiber is equal to or larger than the diameter of the bundle end, and detachably connectable to the bundle end, and (2) the above The laser light oscillators can independently adjust the output light, or (3) the laser handpiece turns on the laser light introduced into the one optical fiber. It is obtained by further comprising a hand switch for full control.

[0005]

A plurality of optical fibers for transmitting laser light from a plurality of laser oscillators having different frequencies, and laser light from the plurality of optical fibers are introduced.
The laser light from each laser oscillator is introduced into the one optical fiber at the same time or individually.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a schematic configuration diagram of an essential part for explaining an embodiment of a laser treatment apparatus according to the present invention. In the figure, 1 and 2 are laser oscillators, for example, 1 is a HeNe laser oscillator, Reference numeral 2 denotes an LD (laser oscillator). The HeNe laser oscillator 1 emits a laser beam having a frequency effective for promoting treatment and extinction of wounds, and the LD 2 emits a laser beam having a frequency effective for pain relief. . In addition, in FIG.
Although an example in which two laser oscillators are provided has been shown, it is easily understood that the present invention is not limited to two and any two or more laser oscillators may be used.

The laser light from the laser oscillator 1 passes through the optical fiber 3 and the laser light from the laser oscillator 2 passes through the optical fiber 4, for example, a housing (schematically indicated by a chain line 10) in which these laser oscillators are housed. (Shown in FIG. 3), the ends of the optical fibers 3 and 4 are bundled in the outer wall to form a bundle end, which is housed in the connector 5.

A connector 6 is connected to the connector 5. A single optical fiber 7 is connected to the connector 6, and a laser handpiece 8 is connected to the tip of the optical fiber 7. The laser handpiece 8 is provided with a switch 9, and by turning the switch 9 on and off, emission of laser light from the laser handpiece 8 is turned on and off. The on / off control of the laser light is to control the drive stop of the laser oscillators 1 and 2 by turning on and off the electric circuit by the switch 9 or to control the introduction of the laser light to the optical fibers 3 and 4. However, the switch 9 may be configured as an optical breaker, and the switch 9 may directly cut off the laser light.

2A and 2B are views showing the joint surfaces of the connectors 5 and 6, wherein FIG. 2A shows the joint end surface of the connector 5 and FIG. As shown in FIG. 2A, the end faces are integrally bundled and bundled and housed in the connector 5, and the end face of the optical fiber 7 (diameter of the optical fiber 7) is the same as that of the optical fibers 3 and 4. Bundle end face diameter D
The diameter D'is substantially equal to the above, and when the optical connectors 5 and 6 are joined together, all the laser light from the optical fibers 3 and 4 is introduced into the optical fiber 7.

Therefore, when the laser treatment apparatus according to the present invention is used, the output of the laser oscillators 1 and 2 is adjusted by operating the operation panel provided on the outer surface of the casing 10 of the laser treatment apparatus. However, the output of one laser oscillator may be 0, and the optical connector 5 and the optical connector 6
When the switch 9 provided on the laser handpiece 8 is operated after joining the laser beams, the laser beams of the laser oscillators 1 and 2 are simultaneously emitted from the tip of the laser handpiece 8.
Alternatively, either one of the laser beams is output. Irradiation with both laser light at the same time, whether to irradiate only one of the laser light, or how much power is irradiated depends on the case, the choice is made by the doctor according to the symptoms, As described above, the operation is performed by operating the keys on the operation panel provided on the outer surface of the housing 10.

[0011]

As is clear from the above description, according to the present invention, it is possible to simultaneously irradiate laser light of two wavelengths or more wavelengths from one laser handpiece. The treatments can be carried out simultaneously and thus the treatment time can be significantly reduced.
Also, for example, while relieving pain, other treatments such as anti-inflammatory treatment can be performed. Further, in the prior art, a plurality of laser treatment devices having different frequencies are prepared and the plurality of treatment devices are selectively used according to the case. However, according to the present invention, one treatment device has a different frequency. Since various types of laser light can be emitted, the number of laser treatment devices can be small, and therefore the cost can be reduced and the space can be saved. Also,
The work efficiency can be remarkably improved.
