る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to light intensity control of a light source of guide light and illumination light for a medical laser scalpel such as an endoscope.

危険性が生じる事となる。 As is well known, the irradiation light for the laser scalpel is invisible light, and in order to confirm the irradiated area such as the affected area, it is necessary to insert a guide light coaxially with the irradiation light for the laser scalpel. Furthermore, it is necessary to observe the entire affected area using illumination light for observation inside the body cavity. If the contrast between the brightness of the illumination light and the guide light decreases, there is a risk that the irradiated area of the laser scalpel irradiation light cannot be confirmed.

Measures such as narrowing down the guide light flux of Ne or xenon lamps to increase the brightness, or interposing a filter in the optical path to give the guide light a coloring effect to distinguish it from the illumination light as a guide light for invisible laser scalpel irradiation, etc. It was hot.

ない。 However, the brightness of the illumination light needs to be increased for observation inside the body cavity, and when glass fibers are used in the optical system, the transmittance decreases significantly, so in order to maintain the brightness of the illuminated area, it is necessary to increase the brightness. It is necessary to increase the brightness, but in such a case, increasing the output of the guide light in order to make the guide light sufficiently recognizable, that is, to increase the contrast between the guide light and the illumination light, is necessary to increase the brightness of the tissue in the body cavity. If a He--Ne laser guide light is used, it is not good because it causes thermal damage and has a negative effect on the observer's eyes due to reflection. Furthermore, reducing the illumination light to provide contrast with the guide light does not provide a sufficient amount of illumination light for observation.

To provide a light source device which controls the amount of illumination light so that the brightness of the guide light and the brightness of the illumination light have a contrast so that the guide light can be visually observed while maintaining the amount of illumination light sufficient for observation.
