The development history of laser therapy instruments. Laser therapy is an important invention in the history of mankind, and widely exists in the fields of medical treatment, beauty and so on. The application of very light in the history of development continued until 1961. With the continuous research of mankind, laser instruments were developed.
Development history of laser therapeutic instrument
As early as 1961, the United States began research on laser biology. In 1962, German Bessis et al. Published “Research on the effect of laser on blood cells”. In 1965, mestez of Hungary studied the biological effect of He Ne laser, summarized the law of the effect of He Ne laser on organisms, and proved that it has the effects of relieving pain, accelerating wound healing, reducing scar tissue and so on. In 1963, McGuff published “Discussion on biological effect of laser”, Goldman published “effect of laser beam on skin”, and fine published “biological effect of laser”.
In 1970, bopohnha and others in the former Soviet Union used He Ne laser to treat hypertension and other medical diseases. Yremypatoba reported 118 cases of hypertension treated by irradiating acupoints and reflex areas. Blood pressure returned to normal in 108 cases. In 1972, bopohnha reported the treatment of bronchitis. The results showed that 21 cases took effect immediately, and the vital capacity increased by 30%. In 1973, Austria plog used laser as an agent for acupuncture and moxibustion to do experiments, and in 1975, it made the first He Ne laser acupuncture and moxibustion instrument for the treatment of diseases at meridians and acupoints, which achieved success. This therapy has been widely used in Europe and Asia. A large amount of data have been accumulated. Hundreds of evidence-based medicine laboratories have confirmed its clinical efficacy, and more than 1000 research reports have been published.
Therefore, this low-intensity laser is an effective treatment. In 1985, the Symposium on medical application of low-intensity laser was held in Japan to prove that the research on low-intensity laser therapy has extended to the fields of effects on the peripheral nervous system, effects on immune function and inflammatory process, regularity of experimental wound healing, and promotion of bone cell regeneration.
Medical laser history
With the development of laser technology, a new applied discipline – laser medicine has gradually formed. The unique advantages of laser have solved many problems that traditional medicine can not solve in basic research and Linchuan application, and have attracted the attention of medical circles at home and abroad.
After Maiman developed the first ruby laser in 1960, he used the welding technology for retinal detachment in 1961, such as zaret, Campbell in 1963, zwen in 1964, Goodman in 1964 and stern in 1964. In Ophthalmology, laser is the earliest and most mature discipline. In some ophthalmic diseases, laser therapy is listed as the first choice. Such as retinal breaks in fundus diseases, central serous retinopathy, diabetes retinopathy Coats disease, and retinoschisis.
Retinal hemangioma, primary glaucoma and laser keratoplasty are used to treat myopia. This treatment method is a new technology of computer technology applied to refractive medicine and a revolution in the field of refractive cornea. Laser keratectomy (PRK), laser in situ keratomileusis and laser subepithelial keratomileusis have been carried out, and the last one is the latest operation.
With the continuous research on laser, laser therapeutic instruments have been widely used, safe and effective in the treatment of diseases and medical cosmetology. Therefore, the development history of laser therapeutic instruments continues to progress.
