【発明の詳細な説明】
本発明は炭酸ガスレーザー光の遮断方法に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for blocking carbon dioxide laser light.
レーザー光は物品の加工用、あるいは患者の治療の目的
て手術用、止血用として使用されている。レーザー発生
装置がコンパクトでかつ操作が簡単なこと、及び物品の
加工速度が早く衛生的であることなどの点から見て、今
後さらにレーザー光の用途が拡大し産業界で広範囲に利
用されるものと考えられる。Laser light is used for processing articles, for surgical purposes, and for hemostasis in the treatment of patients. In view of the fact that the laser generator is compact and easy to operate, and the processing speed of articles is fast and hygienic, the applications of laser light will further expand in the future, and it will be widely used in industry. it is conceivable that.

いる。For example, when treating a patient, a complex surgery that would take two hours using a conventional scalpel or the like is said to be shortened to about eight hours by using a laser scalpel.

われる。レーザー光発生装置は操作性、安全性を考慮し
製造されている。This is because by focusing the laser beam and reducing the beam diameter, it becomes easier to cut small parts. In addition, it does not require much skill, and there are fewer differences depending on the skill of the operator, and it is expected that it will be used widely in surgical applications in the future. Laser light generators are manufactured with operability and safety in mind.
又、レーザービームを所定の位置に照射出来る様、覗き
光学系の装置がついている。It is also equipped with a viewing optical system so that the laser beam can be irradiated to a predetermined location.
しカル操作者の誤認、レーザー光発生装置の整備不良に
より患部以外にレーザー光が照射される恐れがあるため
患部の周囲を保護する必要がある。It is necessary to protect the area around the affected area, as there is a risk that the laser beam may be irradiated onto areas other than the affected area due to a misunderstanding by the operator or improper maintenance of the laser beam generator.

づいて本発明を完成したものである。It also has the ability to absorb water. When protecting the area around the affected area with metal objects, the area around the affected area is protected when the carbon dioxide laser beam is irradiated, but the operator and nurse may be injured by the reflected light from the carbon dioxide laser. On the other hand, water is an excellent material because it absorbs carbon dioxide laser light, but since it is a liquid, no good method has been found to protect the area around the affected area. As a result of research on a method for protecting the area around the affected area from direct erroneous irradiation with carbon dioxide laser light, the present inventor found that it is possible to completely block laser light by using a cellulose sponge that absorbs water. The present invention was completed based on this finding.
即ち、本発明の要旨は炭酸ガスレーザー光を遮断する方
法において、該レーザー光を水を吸収さ門せたセルロー
ズスポンジを用いて遮断することを特徴とするレーザー
光の遮断方法である。That is, the gist of the present invention is a method for blocking carbon dioxide laser light, which is characterized in that the laser light is blocked using a cellulose sponge that absorbs water.
以下、本発明につき詳細に説明する。Hereinafter, the present invention will be explained in detail.

つて製造したものである。Accordingly, in the present invention, cellulose sponge is made by converting the pulp into alkaline cellulose, then adding carbon disulfide to create a solution called viscose via sodium cellulose xanthate, and adding glauber's salt to this viscose solution. It is produced by adding 20% of the total amount of alcohol to form a gel, drying it in vacuum, and denitrifying it.

による事故を防止することができる。This cellulose sponge is made only from cellulose components, and has countless holes through which Glauber's salt has passed, so it has very good water absorbency, capable of absorbing 2 Pi of its own weight, and also has good water retention. Next, in the present invention, instead of using cellulose sponge alone, a cellulose sponge with water-absorbing material such as gauze or cotton cloth pasted on one or both sides may be used. Cover the area around the affected area with a cellulose sponge material like the one above that absorbs water, and let the cellulose sponge absorb the irradiated carbon dioxide laser light to prevent exposure to laser light due to incorrect operation of the carbon dioxide laser. It is possible to prevent accidents caused by

発明につき具体的に説明する。In addition, cellulose sponge becomes flexible and feels good when it absorbs water, so it can be used with confidence without worrying about damaging the area around the affected area. Next, the present invention will be specifically explained with reference to Examples.

Furthermore, when a cellulose sponge that had absorbed enough water was drained, it had absorbed four times as much water. Two types of cellulose sponge and carbon dioxide laser. Ikkou irradiated the material with 10W for 5 times in succession for 0.5 seconds, but only water vapor was generated and there was no discoloration or deformation of the surface of the material.
