Abstract
A medical laser probe to be used as a laser irradiation unit in laser treatment that is performed by irradiating a living body with laser light. The laser probe irradiates laser light uniformly, utilizing laser light effectively by concentration thereof, achieving limited irradiation of laser light and taking countermeasures against stains forming on the probe. The laser probe is provided with (1) a transparent light diffuser for radiating laser light received by a light-guide fiber in the direction along the longitudinal axis of the light diffuser and in radial directions from this axis to the peripheral side surface thereof and (2) a detachable protective diffusion tube for further diffusing laser light radiated from the transparent light diffuser. A reflector may be provided between the light diffuser and the diffusion tube. Further, shielding plates may be provided on the protective diffusion tube.
