概述

以各种形式的激光治疗某些疾病的方法.激光具有与普通光一样的特性，但由于是受激辐射光，所以与一般光线比较，有发散角小，方向性好；光谱纯，单色性好；能量密度高，亮度大；相干性好的特点.治疗作用主要取决于它的波长、强度及作用时间.大功率激光是利用其对组织的物理破坏作用，如外科激光刀的切割、肿瘤的炭化或气化及组织的凝固焊接等.小功率激光主要是利用其对组织的生物学促发作用及对症状的顿挫作用，例如消炎、止痛以及促进组织的再生等.理疗多用小功率激光.小功率氦—氖激光照射可加强甲状腺与肾上腺皮质的功能，影响机体的代谢过程.如照射某些穴位５—１０分钟，可出现良好的降压作用.某些激光对恶性肿瘤有选择性破坏作用.氦—氖激光主要适应症有：原发性高血压、哮喘、支气管炎、神经衰弱、神经根炎、面神经炎、三叉神经痛、静脉炎、扭伤、挫伤、慢性皮肤溃疡、咽炎、扁桃腺炎等.二氧化碳激光主要适应症有疖肿、急性峰窝织炎、急性乳腺炎、术后粘连、腰肌劳损、慢性风湿性关节炎、急性鼻窦炎等.二氧化碳激光烧灼适应症有：色素痣、血管瘤、鸡眼、皮肤原位癌等.氮分子激光主要适应症有：表浅局限性化脓性炎症、感染创面.功率１—２瓦的氩激光穴位照射适用于外伤性截瘫、脑炎后遗症、小儿麻痹后遗症、蛛网膜炎等                                                                                                                                                                                                                                                                                             .In various forms of laser treatment of certain diseases. Laser has the same characteristics of ordinary light, but is subject to stimulated emission light, so light compared with the general, there is divergence angle is small, directional well; spectrum of pure, single-color good; energy density, high-brightness large; coherence and good features. therapeutic effect depends on its wavelength, intensity and duration of action. High-power laser is to use the physical destruction of its role in the organization, such as the surgical laser knife cutting, tumor carbonization or gasification and organizations such as the solidification of welding. Low-power laser is mainly to use its biological precipitating the organization and its effects on symptoms of frustrated role, for example anti-inflammatory, analgesic and to promote tissue regeneration and so on. multi-purpose small-power laser therapy . low-power helium - neon laser irradiation can enhance the function of thyroid and adrenal cortex, affecting the body's metabolic processes. such as exposure to certain acupuncture points 5-10 minutes, there may be a good antihypertensive effect. Some laser for selective cancer damaging. helium - neon laser main indications are: hypertension, asthma, bronchitis, neurasthenia, nerve root inflammation, facial paralysis, trigeminal neuralgia, phlebitis, sprains, contusions, chronic skin ulcers, pharyngitis, tonsillitis and so on. Carbon dioxide laser Boil the main indications are acute honeycomb weave inflammation, acute mastitis, postoperative adhesions, lumbar muscle strain, chronic rheumatoid arthritis, acute sinusitis and so on. Carbon dioxide laser burning indications are: pigmented nevus, hemangioma, corns, skin tumors, in situ. nitrogen molecular laser the main indications are: superficial limitations suppurative inflammation, wound infection. power of 1-2 watts of argon laser acupoint irradiation applied to traumatic paraplegia, brain inflammatory sequelae, polio sequelae, arachnoid Yandeng.
