らかな操作性を満すには技術的限界が存在する。 When using a carbon dioxide laser as a medical laser scalpel, the laser beam is effectively guided to the surgical field.
Conventionally, an articulated flexible light guide, or manipulator, uses several 45-degree reflective mirrors to give the surgeon sufficient freedom of operation and allow the laser beam to scan the surgical field smoothly. is used.
However, in this type of manipulator, there is a rotational moment that depends on the mass and length of the mirror box that houses the 45-degree reflecting mirror in the joint and the right cylinder that rotatably connects the mirror box. Due to the movement synthesized by the individual rotations of the joints of the manipulator, the movement of the manipulator tip lacks smoothness, and there is a technical limit to meeting the fine and smooth operability required by the operator. exists.

がないようにしなければならない。 Carbon disulfide is in the wavelength range of CO 2 laser light
It has a small absorption coefficient for wavelengths from 10.5135 microns to 10.7880 microns (commonly used CO 2 lasers have 14 oscillation lines in this wavelength range), making it a good light guide. 100 to 500 hollow monofilaments filled with high-purity carbon disulfide and approximately 50 cm in length are bundled into the densest packing, and each end is approximately 10 mm long with a flattened end surface. They are fixed to each other with adhesive, and the middle part is left free in the same way as a glass fiber light guide to provide flexibility. Reference numerals 2 and 3 are cylindrical metal fittings that are located at both ends of the fiber bundle and hold the fiber bundle, and window materials 4 and 5 made of zinc selenide with a surface coated with a non-reflective coating of 10.6 microns are fitted into the ends of the metal fittings. It forms the input and output ends of the laser beam. A space 6 is provided between the window materials 4 and 5 and the fiber bundle, and is filled with carbon disulfide in a bubble-free manner, similar to the core portion 1 of the fiber monofilament. The effect of this space 6 is important, and the first is that it eliminates the technical difficulty of directly sealing with the window materials 4 and 5 so that the medium liquid filled in the core part 1 does not leak.
Furthermore, as will be described later, when pressurized reflux of the medium liquid is performed, it serves as a reservoir bar and facilitates the introduction of light into the fiber. Cylindrical metal fittings 2 and 3
A flexible tube 9 made of silicone rubber or the like is connected between the two to give overall flexibility to the liquid fiber light guide tube. Reference numerals 7 and 8 are an inlet and an outlet for the coolant 10 attached to the cylindrical fittings 2 and 3, respectively. Alcohol or mineral oil coolant 1
The liquid fiber light guide monofilament is cooled to around 0° C. and circulated through the flexible tube 9 through the inlet and outlet ports 7 and 8 to cool the liquid fiber light guide monofilament and remove the heat generated due to residual absorption of carbon disulfide. In the liquid fiber light guide tube, the carbon disulfide filling part and the cooling liquid part must be completely separated so that the two liquids cannot mix.

る。 FIG. 2 shows an enlarged cross-sectional view of a portion of the liquid fiber light guide bundle. 11 is a monofilament, which is a so-called cladding; 1 is carbon disulfide as a core; and 12 is an adhesive filler for airtightly bonding both ends of the light guide. In the case of liquid fiber light guides, the manufacturing technology for the artificial polymer hollow thin sleeve that makes up the cladding has already been established for dialysis hollow sleeves for artificial kidneys, etc., but for this purpose, both the inner and outer surfaces must be smooth. No. However, since the wavelength of the propagating laser light is 20 times that of visible light, the smoothness required for visible light is not necessary. It is sufficient if the surface roughness does not exceed 1 micron.
Also, since the laser beam is parallel incident, the core
The value of the refractive index of the cladding does not have to be a relatively specific value, but only needs to be lower than the refractive index of the core. Commercially available carbon disulfide is contaminated with sulfur-containing organic matter, so it should be purified sufficiently through fractional distillation, etc. Also, the boiling point of carbon disulfide is as low as 46.25°C, so Reflux cooling must be sufficient to suppress temperature increases due to external temperature and internal heat generation. In order to raise the low boiling point of carbon disulfide as a light guide medium and to suppress the generation of bubbles, the carbon disulfide filled part is pressurized and refluxed and cooled during the reflux, thereby making it possible to use the indirect cooling method as in this embodiment. There is no need to adopt. Carbon disulfide was used as an example of the light guide core material, but it is a liquid with an extremely small absorption coefficient in the 10 micron band, and a refractive index that meets the optical fiber configuration conditions between that of the cladding and the refractive index of the cladding. You can use it if you have it. For example, a mixed solution of carbon disulfide and carbon tetrachloride satisfies the above conditions and also contributes to physicochemical stabilization. Also, considering the refractive index of the cladding material, dimethyl formamide is an effective core material.
又、目的によつては液体フアイバーを束として
用いず一本（モノフイラメント）で用いることも
できることは勿論である。又、入射端と出射端の
フアイバー内径を変えることも自由である。 Furthermore, depending on the purpose, it is of course possible to use the liquid fibers as a single fiber (monofilament) instead of as a bundle. Furthermore, it is also possible to freely change the inner diameter of the fiber at the input end and the output end.

の効果は極めて大である。 By using the liquid fiber light guide of this invention as a light guide path for CO 2 laser light, and connecting an irradiation tube with a condensing lens to an irradiation chip at one end, a so-called handpiece type laser scalpel device can be created. The effect is extremely large because the operator can finely and smoothly operate the laser scalpel with a much greater degree of freedom than in the case of a manipulator with an articulated light guide path.
