PURPOSE: To easily perform assembly and disassembly easily when replacing parts, etc., and prevent the inside from being polluted by bacilli, etc., even after disassembled condition. CONSTITUTION: A fiber 4 for light guide, which leads the laser beam from a laser light generation source, and an inner cylinder 8 are made free of mounting and removal, and the inner cylinder 8 and an outer cylinder 9 are made free of mounting and removal, and a probe 6 is connected freely of mounting and removal to the tip of the outer cylinder 9. The laser beam from the laser light generation source 2 is condensed on the incidence end of the probe 6 through the condensing lens 17 from the output end 10 of the fiber 4 for light guide, and it is applied to the affected part from the emission end 25. The fiber 4 for light guide and the inner cylinder 8 are connected airtightly by the first connection means, and the inner cylinder 8 and the outer cylinder 9 are connected freely of mounting and removal by the second connection means. Even if it is in the condition that the outer cylinder 9 is removed from the inner cylinder 8, the inside of the inner cylinder is sealed, which prevents the pollution. |
