Laser Light Application In Medicine
Journal Title: Український журнал медицини, біології та спорту - Year 2017, Vol 8, Issue 6
Abstract
The article deals with the recent laser light application in medicine experience. Laser technology development became the basis for innovative scientific and technical field – laser medicine. It studies connection between coherent monochromatic electromagnetic radiation and different biological structures. The purpose of the study is to examine the properties of laser radiation, the structure and types of laser installations, possibilities of laser application in medicine, and also in the physics learning in educational institutions. Laser light is successfully used in surgery, oncology, ophthalmology, therapy, dentistry, urology, gynecology, maxillofacial surgery, neurosurgery, endoscopy, physiotherapy. Discovering of laser photohydraulic effect offers wide opportunities for plastic surgery conducting. Low-intensity laser light is applied for the treatment of wounds, ulcers, and skin diseases in oncology. Mainly there are two main directions of laser application in medicine: as an instrument for influence on different kinds of biological objects and as research instrument. According to scientific experiments’ results and data, there were no deep dehydration, tissue evaporation, defects formation under the influence of pulsatile or continuous laser radiation (power density of about 105W/m2) in the first group observed. From this perspective, laser is considered to be a unique light source in spectral studies, such as laser microscopy, holography etc. in the second group. Thus, advantages of laser radiation application in medicine are: exact localizing of the coagulation place and soft heating of tissues around the region of coagulation is due to the short exposure time. The monochromaticity of laser light reduces chromatic aberration effect of the eye and facilitates observation. Moreover, laser light proved itself to have widespread use in various fields of laser medicine, which confirms the importance of further studying of laser radiation properties in medical and biological physics.
