PURPOSE:To reduce the diameter of a laser probe and improve the irradiation efficiency by melting and integrally forming the top edges of the guide cores of a plurality of laser guides, and constituting an annular irradiation part having a hollow part and forming a channel after connecting the passages formed in the laser probe body, in the hollow part. CONSTITUTION:When thrombus 37 in a vessel 36 is eliminated, a laser probe 1 is inserted into the vessel 36, and the top edge is introduced into the thrombus 37 part. In this case, a guide wire 14 is introduced from the mouth part 16 of the laser probe 1, and a guide wire 14 which projects from a lead-out hole 13 is inserted to the passing position through the thrombus 37 in the vessel 36, and the laser probe 1 is introduced, having the guide wire 14 as guide. When the second laser oscillator 22 for therapy is irradiation-operated when mirrors 24, 25, and 26 are at the original positions, the laser beam L2 is introduced, divided at laser guides 3a, 3b, 3c and 3d installed on the installation mouthpieces 31, 32, 33, and 34, and the laser beam L2 is irradiated towards the thrombus 37 from the irradiation surface 12 through an irradiation part 11 which is formed integrally with the top edges of the laser guides, and the thrombus 37 is removed. |
