激光是一项新兴技术,在国内外已广泛应用于工业、农业、军事和科学研究等许多领域中;在医学方面,用激光诊治疾病也较普遍,并且,还有人通过小动物实验,初步研究了激光的生物学效应和作用机理,为了探索激光在大动物创伤外科上的应用,我们通过给马造成无菌手术创和污染缺损创,用氦氖激光束进行照射的研究,进行了一系列的实验观察,试对氦氖激光的某些作用机理进行了阐述,初步为兽医外科临床应用氦氖激光提供了一些理论和技术上的依据。 Laser is an emerging technology and has been widely used in many fields such as industry, agriculture, military and scientific research at home and abroad. In the field of medical science, laser is also used to diagnose and treat diseases. In addition, In order to explore the application of laser in the traumatic surgery of large animals, we conducted a series of studies on aseptic surgery and contamination defects created by irradiation of horses and irradiation with He-Ne laser beam. The experimental observation shows that some of the mechanism of helium-neon laser is expatiated, which provides some theoretical and technical basis for the clinical application of helium-neon laser in veterinary surgery.
