PURPOSE:To provide a therapeutic laser device which can vary the irradiation range of laser beams by a simple operation and can prevent the excessive output laser beam from irradiating. CONSTITUTION:A cover 1 has a cut part 4 in the vicinity of one edge (cured surface 8 side) of a cylindrical body and has a guide groove 9 at a part of the cylinderical body. A cover 2 has a guide groove 10 on a cylindrcal body having the smaller diameter than that of the cylindrical body of the cover 1 and has a lens 5 installed at one edge. A cover 3 is formed by arranging an optical fiber 6 and a uniform light irradiating lot 10 on a cylindrical body having the smaller diameter than that of the cylindrical body of the cover 2 so that each edge surface is opposed. The cover 3 is fitted with the cover 2, and the cover 2 is fitted with the cover 1. On the cover 3, a pin 5 which is inserted into a guide groove 8 and the guide groove 9 is installed. The radiation range of laser beams can be varied by revolving the cover 3 for the cover 1. |
