However, if laser light is applied to areas other than bruises, it will cause damage to normal tissues. For this,
In the past, the scanning control of laser light emitted by skilled doctors was strictly controlled.
As a result, the treatment time is prolonged, and even when operated by such a skilled person, the laser beam often irradiates areas other than the necessary areas, resulting in damage to normal living tissue.

せることができる。 The figure shows a preferred embodiment of a laser irradiation device 12 that irradiates laser light to a bruise 10 as an affected area requiring treatment, and the laser irradiation device 12 has a laser irradiation section 14 that includes a laser light source and a control device. Laser light 1 irradiated from the laser irradiation unit 14
00 is reflected by the scanning mirror 16 and guided to the laser irradiation point 100a on the birthmark 10, the birthmark tissue in that area is burned away, and the birthmark 10 can be treated by regenerating new skin tissue. The scanning mirror 16
is rotationally controlled in the direction of arrow AB by a scanning mechanism (not shown), and can scan the laser beam 100 in accordance with the bruise 10. In the embodiment,
This scanning control can be performed in a manner similar to the standard television scanning method, in which return scanning is performed in a short time, and as a result, ablation treatment of bruise tissue can be performed only during scanning in one direction. In the figure, a laser beam 10 is mechanically rotated and scanned by a scanning mirror 16.
The scanning of 0 is done in the x direction, with this
The laser irradiation device 12 is scan-controlled in the y direction by a moving device (not shown), and as a result, the laser beam 1
00 can scan the surface of the birthmark 10 along the xy plane, and can burn away the birthmark tissue to the required state.
