Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a laser medical device using a semi-rigid laser.

Conventional Structure and Problems It is well known that symptoms such as stiff shoulders can be treated by irradiating the human body with laser light.

As a medical device that synthesizes and irradiates laser beams of different orders, /
For example, there is one disclosed in Japanese Unexamined Patent Publication No. 58-89278.

In FIG. 1, semiconductor lasers 1a and 1b.

1c and 1d are arranged in a link shape to form a condenser lens 2a.

2b and 2C22d to focus the light on the center of the circle.

A reflector 3 with a pyramidal structure is arranged at the center of the circle, and when the light is focused again using an O1 condenser lens 4 almost perpendicular to the traveling direction, the laser spot becomes sharp when the image is formed close to each other. . In these various configurations, if the loss of the optical system is ignored, the output will be 1.4 times higher. A semiconductor laser has a small light emitting spot and the laser body is large compared to the spot diameter, so it is not possible to reduce the spot spacing by arranging the lasers in the same direction. This device allows multiple laser spots to be arranged closely.

By the way, it is said that the therapeutic effect is due to the polarization of light, and in the configuration shown in FIG. 1, the polarization direction i1. ', ', lk''; 1. +, , :<. Therefore, as shown in Figure 1, 18・1C and 1
If the polarization directions of b and 1d are perpendicular to each other, there is a drawback that the treatment efficiency will be poor if four lasers are irradiated onto the same patch.

OBJECTS OF THE INVENTION The present invention aims to 1: eliminate the above drawbacks and 1: enhance the therapeutic effect of polarized light.

Structure of the Invention The present invention is a semiconductor laser medical device that includes a plurality of semiconductor lasers and a prism for synthesizing a plurality of lights.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described with reference to FIG. Items that overlap with those in Figure 1 are given the same numbers. The semiconductor lasers 1a' and 1c' are rotated 900 times from the case shown in FIG. The condensing lenses 2a to 2d are the same as those in the conventional example, but the lens 4' is different from the conventional example and is configured so that the individual laser beams are approximately parallel beams.

With this configuration, the polarization directions of the four lasers match,
Is it a therapeutic effect?

Also, in terms of intensity, considering coherent interference, it can be expected that if the location and time are limited, the intensity will increase by (4)2=16 times.

Effects of the Invention JR, l - As explained, according to the present invention, by combining the outputs of a plurality of semiconductor lasers with the polarization directions aligned, it is possible to locally increase the instantaneous power, and also to align the polarization directions. This can also improve the therapeutic effect.
