摘要： A device for detecting failures in a laser transmitting passage includes an inner tube (80) made from an optical hollow waveguide and having a first space (122) through which laser is transported, an outer tube (78) surrounding and extending along the inner tube, and a detector which recognizes a first condition in which the first space is fluidly disconnected from the second space and a second condition in which the first space is fluidly connected to the second space. The first and second conditions can be determined from a pressure, flow rate, gas concentration, ingredient of gas, or temperature in first or second space.

摘要： A medical laser treatment device comprises a handpiece having a handpiece body and a laser probe to be attached to the handpiece body, a laser light source, and a light transmission member which guides laser light to the handpiece. The laser probe has a fiber probe having an emission face through which the laser light is emitted to an irradiation region, an annular protection tube which covers the peripheral face of the fiber probe, and a holder which holds the fiber probe and the protection tube. The protection tube has a curved part extending with being curved. A first fiber curved part is formed in the fiber probe by passing the fiber probe through the protection tube. A second fiber curved part having a radius of curvature is smaller than that of the first fiber curved part is disposed in a tip end portion of a fiber probe.
