The Application of Laser in the Medical Industry
Release time：2024.02.23
Views：2296Laser in medicine refers to the use of stimulated emission amplification to generate high coherence and intensity monochromatic light. Laser has a wide range of applications in the medical field. Laser medicine is an emerging interdisciplinary field that includes the use of new laser technologies to study, diagnose, prevent, and treat diseases. Laser has been applied to various clinical departments such as internal medicine, external medicine, gynecology, children, eyes, ear, nose and throat, oral cavity, skin, tumor, acupuncture and moxibustion, physiotherapy, etc. It not only opens up new research avenues for the study of life sciences and the occurrence and development of diseases, but also provides new means for clinical diagnosis and treatment of diseases.
Types of medical lasers
There are several commonly used medical lasers: ① He-Ne laser. Output a red laser directly to the material. The characteristics are simple structure, convenient operation, low price, long service life, and over 10000 hours of use. Used for anti-inflammatory, analgesic, or for laser acupuncture and physical therapy Carbon dioxide laser. Output a far-infrared laser with a wavelength of 10.6 μ m. The characteristic is high output power, used as a laser knife for burning, cutting, and vaporization Argon ion laser. Green laser has the characteristic is high power and within the visible light range. Used for photocoagulation therapy, such as for fundus diseases and duodenal and gastric ulcers. ④ Neodymium doped yttrium aluminum garnet laser. Output near-infrared laser with a wavelength of 1.064 μ m. The characteristic is high output power, deep and uniform effect on tissues, affinity for red tissues, and can be transmitted through optical fibers. It is often combined with an endoscope to enter the cavity for the treatment of tumors, polyps, bleeding, etc., and is one of the most commonly used lasers.
Other excimer lasers, copper vapor lasers, ruby solid-state lasers, semiconductor lasers, etc. are also frequently used in clinical practice.
