Apr 23, 2020

As one of the most advanced manufacturing and processing technologies in the world, laser technology has been widely used in industrial production, communication, information processing, medical cosmetology, 3D sensing, military, cultural education and scientific research, and has become a major driving force for the advancement of science and technology. Because the laser has the characteristics of high brightness, high directivity, high monochromaticity and high coherence. As soon as it appeared, it was welcomed by the industry and attracted great attention from the medical and biological circles. In 1961, zaret, Campbell and others used laser to study retinal detachment welding, which was soon used in clinic. In 1981, the World Health Organization listed laser medicine as a discipline of medicine.

Laser medicine is a special subject that uses laser technology to study, diagnose and treat diseases. Laser medicine has a wide range of clinical application, high accuracy and small side effects. It is an ideal method for clinical treatment of some diseases and plays an increasingly important role in medical research and clinical practice. The application of laser in medical field can be divided into two categories: application in treatment and application in measurement and diagnosis. According to different applications, medical laser can be divided into Ophthalmology, gynecology, dermatology, Urology, dentistry and cardiology. Currently, ophthalmology and dermatology are the main departments.

Semiconductor laser has the advantages of small size, light weight, low cost, long life, wavelength selection, stable output power, simple power drive system, etc. it is especially suitable for medical equipment. Its clinical application covers almost all other types of laser applications.

Free beam CO2 laser is used in CO2 laser surgery, which usually adopts the way of non-contact between light beam and skin tissue to provide more convenient conditions than conventional surgery, including reducing mechanical damage, increasing the protection of surrounding tissue, and easier to maintain aseptic surgery. Compared with other laser surgery, CO2 laser scalpel has strong cutting ability, large tissue absorption coefficient and tissue The continuous CO2 laser is widely used in the clinical treatment of surgical operation because of its small penetration concentration, less injury to arteries and blood vessels during the operation.

With the development of laser medicine and the improvement of laser technology, the spring of medical laser market is coming. Just take beauty as an example: at present, the number of hairdressing practitioners in China has grown from 120000 at the beginning of reform and opening up to more than 16 million now, there are nearly 4 million enterprises, more than one million specialized beauty agencies, and the beauty and hairdressing industry is expanding rapidly with a growth rate of 15% every year. The demand of domestic medical institutions for laser medical equipment keeps a strong growth trend. With the continuous improvement of people's pursuit of beauty, laser technology is more widely used in the field of medical beauty. At present, the market scale of laser beauty instruments in beauty salons in China is constantly expanding, providing huge business opportunities for the future development of medical laser market.

In addition to beauty, laser is more and more widely used in the medical field, and a large number of medical laser equipment is needed for support, such as marking, detection, treatment, surgery and so on. At present, laser medical centers have been set up in major hospitals nationwide, and 80% of small and medium-sized hospitals have set up laser medical departments. The demand for laser medical equipment in the domestic medical sector has increased significantly. The sales volume of medical laser equipment will be greatly increased, and the market space of medical laser will continue to expand.

Looking forward to the future, with the deepening of basic research, new laser diagnosis and advanced treatment instruments continue to appear, clinical applications will continue to expand, and the laser medical industry will gradually expand. It can be predicted that as long as the laser technology exists, the medical laser market will get greater development.
