Abstract

PURPOSE:To obtain the laser irradiating device having a visible lightguide device with which a guidelight can be coaxially superposed on the irradiated laser beam using a simple constitution by a method wherein a mixing device, used to superpose the guide light on one or both of the first laser beam and the second laser beam and a device, with which the first and the second laser beams can be turned ON or OFF independently to each other are provided. CONSTITUTION:When each source of laser beam is in the state of oscillation and shutters 7 and 8 are opened, the first and the second laser beams 4 and 6 are irradiated. the irradiated first laser beam 4 passes through dichroic mirrors 9 and 10, and guided to the first lightguide path 16. At this point, when reflecting mirrors 14 and 15 are located at positions A and B respectively, a guiding light 5 is reflected by the mirror 14, and superposed on the laser beam 4 by the dichroic mirror 9. In the same manner as above, the second laser beam 6 is reflected by the mirror 15, and skperposed on the laser beam 4 by the dichroic mirror 10. In other words, the blended luminous flux of the first laser beam 4 and the second laser beam 6, wherein the guide beam 5 is superposed, is irradiated from the first light guide path 1.

と報告されている。Conventionally, several laser irradiation devices have been proposed that can irradiate two working laser beams with different wavelengths simultaneously or selectively. When the irradiated part is a living body, it is known that the interaction between the living body and the laser light varies greatly depending on the wavelength of the irradiated laser light. Therefore, it has been reported that these laser irradiation devices can utilize the characteristics of laser surgery to proceed with surgery more effectively by appropriately using the working laser light, compared to the case where only the immediate laser light is irradiated. ing.
