2. 196 1 year, the world's first medical laser machine, Ruby Retinal Coagulation Machine, came out in the United States, and American doctors Campbell and Koster welded the detached retina. Sonlon, Zeret, Eichler and others first published papers such as Physiological Function of Laser, Eye Injury Caused by Light Pulse, Photocoagulation Produced by Coherent Light Source, Physiological Basis of Laser Application in Biomedicine, etc. 1962, Bessis Group of Europe reported their research results of irradiating organelles with ruby laser. From 65438 to 0963, the Soviet Union also began to publish articles on the biological effects of lasers. 1966, Kazuhiko Womei and others published the first batch of laser medical papers in Japan.
3. China's first domestic ruby laser was made in 196 1, and 1965 started the animal experiment of ruby laser retinal coagulation in Beijing Tongren Hospital. By the end of 1960s, there were hundreds of international papers on laser medicine, with more than 10 monographs.
4. Since 1964, the United States, Britain, the Soviet Union and other countries have successively held academic conferences on laser biomedicine. As a result, laser medical research has sprung up all over the world, but as a discipline, it is still in the primary stage and very immature. For example, in clinic, although the experiment of laser welding detached retina has been done for a long time, its real application in clinic began with 1968. Another example is 1963, which is the first attempt to use ruby laser to eliminate atherosclerotic plaques in corpses, but it has almost stopped for more than 20 years due to the lack of corresponding technology and equipment. It can be said that the 1960s was only the basic research stage of laser medicine, but "laser medicine" as a new discipline is gradually taking shape.
