ABSTRACT:
A laser treatment device provided with a laser light source, a laser-light transmitting optical fiber for transmitting laser light output from the laser light source and a probe for guiding the laser light transmitted by the laser-light transmitting optical fiber to an object to be irradiated. Further, the probe is constituted by a laser-light guiding optical fiber separated from the laser-light transmitting optical fiber. Moreover, a cooling chamber for cooling the optical fibers is provided in the neighborhood of an output end of the laser-light transmitting optical fiber, from which the transmitted laser light is output, and an input end of the laser-light guiding optical fiber, from which the laser light output by the laser-light transmitting optical fiber is input to the laser-light guiding optical fiber. Thereby, a medical treatment of a deep part of an affected or diseased region can be achieved without worsening the state of the exit of the laser-light transmitting optical-fiber. Moreover, the output end of the laser-light transmitting optical-fiber can be kept in a favorable condition even after the medical treatment of the deep part of the affected region. Thus there is no obstacle to the next treatment thereof.
