背景:自1961年世界上第一台红宝石激光器研制成功以来,由于其具有功率/能量高,方向性好以及与生物组织相互作用的独特性能因而在临床上得到了广泛的应用。并随着不同种类的激光器的研制成功,激光器在临床上的应用也更加广泛。目的:通过对不同种类的医用激光器在临床上应用的比较,明确未来激光医疗发展的方向。研究选择:选择关于激光器临床应用的文献,不排除其是否为随机、盲法等论证推荐的文章。数据来源:对1994-01/2004-01年之间关于激光临床应用、激光康复方面的资料进行全面的检索,检索手段包括电子检索、手工检索等。数据提取:对检索到的激光临床应用、激光康复方面的研究文章中相关信息进行综述。主要观察指标:对临床上不同种类的激光器在体积,光电转换效率、波长、治疗费用等方面进行比较。结果:通过临床反馈和比较分析,半导体激光器在针灸理疗、牙病治疗、激光美容、激光手术等方面治疗效果明显优于其他类型的激光器。结论:越来越多的临床病例表明用半导体激光器进行治疗,可以取得比其他类型激光器更好的疗效。由于半导体激光器的输出波长非常丰富,而且正朝着短波长方向扩展,并随着半导体激光器功率的进一步提高有可能在激光医疗方面取代气体和固体激光器。
Background: Since 1961 the world’s first ruby laser was successfully developed, it has been widely used clinically due to its unique properties of high power / energy, good directivity and interaction with biological tissues. And with the successful development of different types of lasers, lasers are also more widely used in clinical applications. Objective: To compare the clinical application of different types of medical lasers to clarify the future direction of laser medical development. Research options: Select the literature on the clinical application of lasers, do not rule out whether it is random, blind and other arguments recommended articles. Data source: A comprehensive search of information on laser clinical applications and laser rehabilitation from 1994-01 to 2004-01 was conducted. The means of retrieval included electronic retrieval and manual retrieval. Data Extraction: The retrieved information on the clinical application of laser, laser rehabilitation research articles are reviewed. MAIN OUTCOME MEASURES: The clinically different types of lasers were compared in terms of volume, photoelectric conversion efficiency, wavelength, and treatment costs. Results: Through the clinical feedback and comparative analysis, the semiconductor laser in acupuncture and moxibustion treatment, dental treatment, laser beauty, laser surgery, etc. is much better than other types of laser treatment. Conclusion: More and more clinical cases show that the treatment with semiconductor laser can achieve better curative effect than other types of lasers. Since the output wavelength of a semiconductor laser is very rich and expanding toward a short wavelength, it is possible to replace gas and solid-state lasers in terms of laser medical treatment with the further improvement of the power of the semiconductor laser.
