PROBLEM TO BE SOLVED: To improve the efficiency of a laser surgery by reflecting a laser beam by a reflection mirror positioned at the tip of a positioned probe, focusing it at a desired position by a convergent lens, linking and moving the reflection mirror and the convergent lens and moving a focus as prescribed. SOLUTION: The reflection mirror 22 is arranged near the tip of the probe 10 are the reflection mirror 22 is irradiated with the laser beam 36 through an inner side tube 14. The laser beam 36 is reflected by being added with the angle of about 90 degrees by the reflection mirror 22 and radiated through a side opening 26 to the direction of a tumor A. The convergent lens 20 is moved by the movement of the inner side tube 14, the laser beam 36 is converged to a desired focus position 37 and the tumor A is removed. In this way, by linking and moving the reflection mirror 22 and the convergent lens 20 by the linked movement of a second tube 16 and the inner side tube 14 and performing focusing at the desired position, an operation is efficiently performed. |
