性が低下しないことが必要である。Conventional technology Laser scalpel devices or laser processing devices that use a carbon dioxide laser as a light source do not have a suitable optical fiber for passing the carbon dioxide laser light, and laser light irradiation is performed using a mirror-articulated light guide path made up of multiple mirrors. However, attempts have been made to develop flexible optical fibers.9 As a result, for example, KR8-
Infrared optical fibers made of halides such as Ct 5 have come into practical use.
Although polycrystalline infrared optical fibers made of silver chloride and silver bromide as shown in Publication No. 1-209407 have come into practical use, these single crystals made of halides or chloride bromide A high-purity single-crystal material made of silver is heated to a temperature slightly lower than the melting point of this material, and in a slightly softened state, it is extruded under pressure using a die with a thin nozzle.It is spliced with polycrystalline infrared optical fibers and is exposed to laser light. The problem to be solved by the present invention is that the characteristics of the infrared optical fiber do not deteriorate over a long period of time.

わちアンストガス経路を設けた構成としたものである。In addition, the laser scalpel device requires a low power of up to 30W (the laser processing device requires a high power of 30W or more, but the modified fiber probe requires a high power of 30W or more).
Scattered light from the infrared optical fiber is absorbed by the infrared optical fiber's holding member, and this heat causes the infrared optical fiber to generate heat and even melt, which is the cause of an increase in the temperature of the infrared optical fiber or a decrease in power resistance. However, the present invention solves the above-mentioned problems, and although the purpose of the present invention is to provide an optical fiber probe that can withstand use at high output and does not reduce transmission efficiency over a long period of time, it is a means to solve the problems. In order to achieve the above purpose, the polycrystalline infrared optical fiber housed and held in a protective tube is housed in a resin jacket tube, and connectors and holders to which condensing lenses or infrared light transmitting members are fixed are attached near both ends of the polycrystalline infrared optical fiber. The connector is provided with two gas inlets, and one gas path, that is, an unstuck gas path is provided between the protective tube and the resin jacket tube.

を取りまく空間が乾燥ガス１２で置換される。In FIG. 2, 17 is a racer irradiation device having a racer oscillator 18, and houses therein a cylinder (not shown) containing dry gas 12 and a regulator (not shown) for adjusting the gas pressure. Also, when the optical fiber probe 19 is connected to the laser oscillator 18 of the laser irradiation device 17, which houses a pump or cylinder for supplying the assist gas 13 inside, the dry gas 12 is injected under pressure. The air flows from the input side to the lower part of the input side, passes through the protective tube 2, and fills the gap between the infrared optical fiber 3 and the infrared light transmitting member 16 and the holder 6. This allows the two protective tubes to escape from the input side lower part of connector 5.

得られもFIG. 3 shows the change over time in the transmission efficiency of the infrared optical fiber 3 with the dry gas 12 flowing therethrough. As is clear from the figure, there is less decrease in transmission efficiency compared to the conventional infrared optical fiber in an air atmosphere (Figure 5).The spectral transmission characteristics of this infrared optical fiber 3 are shown in Figure 4.Dry gas atmosphere Assist gas 13i:L prevents moisture from entering the atmosphere, and no increase in absorption loss at a wavelength of 6.2 μm, which indicates moisture content, was observed even after a long period of time. The gas is pressure-inflowed from the assist gas inlet 11, which is the path described above, to the assist gas opening 8 and flows into the jacket tube 4.
At this time, the assist gas 13 (the assist gas 13) flows around the protective tube 2 and the holder 6 to cool them, and the infrared optical fiber is generated by the scattered light during laser irradiation. According to the present invention, laser irradiation is suppressed by the cooling effect of the assist gas flowing through the path formed in the optical fiber probe. It prevents the infrared optical fiber from absorbing heat due to scattered light, prevents it from melting due to temperature rise, and improves power resistance.Furthermore, the dry gas prevents moisture from entering the infrared optical fiber, reducing transmission efficiency over a long period of time. can be prevented and stable characteristics can be obtained.
