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： In a laser surgical unit having a contact laser probe (1), a hydroxyl group (13) is included in the contact laser probe so that a laser beam is partially absorbed by the hydroxyl group (13) to heat the contact laser probe (1) for transmission to living tissue. Consequently, a coagulation layer is formed in the living tissue along with vaporization and incision. At least a part of the contact laser probe (1) is made of a material which contains the hydroxyl group (13) generally in an amount of between 0.5 and 10 ppm. Alternatively, the hydroxyl group (13) may be included only in a portion adjacent to a surface of a tip portion of the probe (1). As a further alternative, a coating film containing the hydroxyl group (13) may be attached to the tip of the contact laser probe (1). The laser beam preferably has a wavelength between 1.5 and 15 .mu.m. For example, use is made of an Er:YAG laser beam a Ho:YAG laser beam, or a CO.sub.2 laser beam. The laser surgical unit of the above-mentioned structure is excellent in manipulatability, capable of safely and uniformly cutting living tissue, and capable of successively performing hemostasis.

摘要： A laser treatment device provided with a laser light source, a laser-light transmitting optical fiber for transmitting laser light output from the laser light source and a probe for guiding the laser light transmitted by the laser-light transmitting optical fiber to an object to be irradiated. Further, the probe is constituted by a laser-light guiding optical fiber separated from the laser-light transmitting optical fiber. Moreover, a cooling chamber for cooling the optical fibers is provided in the neighborhood of an output end of the laser-light transmitting optical fiber, from which the transmitted laser light is output, and an input end of the laser-light guiding optical fiber, from which the laser light output by the laser-light transmitting optical fiber is input to the laser-light guiding optical fiber. Thereby, a medical treatment of a deep part of an affected or diseased region can be achieved without worsening the state of the exit of the laser-light transmitting optical-fiber. Moreover, the output end of the laser-light transmitting optical-fiber can be kept in a favorable condition even after the medical treatment of the deep part of the affected region. Thus there is no obstacle to the next treatment thereof.

摘要： A laser device includes first and second laser transmitting passages. The first laser transmitting passage in the form of tube has an interior opened at its first and second ends. The second laser transmitting passage has first and second ends. The first end of the second laser transmitting passage is spaced away from but optically connected with the second end of the first laser transmitting passage. This allows that laser transmitted through the first laser transmitting passage is guided into the second laser transmitting passage. Air, on the other hand, is transmitted through the first laser transmitting passage to impinge on the first end of the second laser transmitting passage for cooling.
