Medical science is the earliest, most extensive and most active frontier subject in which laser technology is applied. There are dozens of varieties of laser medical equipment used clinically, including various wavelengths from ultraviolet to visible light and infrared, continuous, pulse, giant pulse, super pulse and other output modes.
Laser surgery is a general name for all kinds of operations, such as using laser instead of knife, scissors, saw, chisel, etc. to remove the focus of tissues by means of separation, cutting, excision, drilling, osteotomy, etc., and anastomosing tissues, blood vessels, nerves, etc. Laser surgery has many incomparable advantages over other methods: First, it has less damage to the surrounding normal tissues, faster wound healing and smaller scars; Secondly, the hemostatic effect is good, the hemostatic time is one-fourth of that of the electrotome, and the effect is 2-4 times of that of the electrotome, which can greatly shorten the operation time; In addition, the laser can be transmitted by optical fiber, and can be coupled with various surgical microscopes to perform various fine microsurgery; It can also be used in combination with various endoscopes or puncture needles for various interventional operations; In addition, laser surgery has no interference with various monitoring instruments during operation, which is very important in some operations, especially neurosurgery.
Laser can produce monochromatic light with high energy and precise focus, and it has certain penetrating power. When it acts on human tissues, it can produce high heat locally. Laser cosmetology is to use this characteristic of laser to remove or destroy the target tissue and achieve the purpose of cosmetology. Including laser cutting and laser skin peeling. In recent years, with the emergence of different wavelength lasers, high-energy ultra-pulse CO2 lasers, variable pulse lasers and erbium lasers, high-tech laser cosmetology is coming into our lives more and more. The biggest advantage of laser beauty: Laser can thoroughly treat all kinds of skin symptoms and repair skin texture, which can achieve the purpose of killing two birds with one stone. The combination of modern laser technology and clinical medicine can improve or restore the congenital defects of appearance and appearance through treatment, leaving no scars on the skin after treatment, so that you can regain your confidence in beauty.
The biggest advantage of laser cutting is less incision bleeding and clear surgical field. At present, the ultra-pulse laser is used to gather the energy emitted by the laser and release the energy in an instant through a special switch. The powerful energy quickly vaporizes the tissue, which not only cuts quickly, but also reduces the heat conduction around the incision to the minimum, and the damage to the tissue around the incision is minimal. It has been used in double eyelid surgery, pouch plastic surgery, facial wrinkle removal, etc., and achieved good results.
Laser skinning uses laser grinding technology. Its principle is to change the focusing characteristics of the laser to make the laser spot become a spot, and then use a pattern generator to scan the spot according to a certain pattern, so that the high heat generated by the laser spot in an instant will remove the target tissue within the scanning range. The intensity and density of each spot, the shape and size of the scanned image are controlled by a computer, so as to accurately control the depth of removing the target tissue and achieve the purpose of treatment. Laser skin replacement not only overcomes the shortcomings of traditional methods such as easy bleeding and difficult depth control, but also stimulates skin elastic fibers to shrink. The contraction of elastic fibers can tighten the skin, further promote the disappearance of superficial wrinkles, and the wrinkle removal effect is more obvious.
More and more diseases are treated with laser, which is a substitute for other treatments and represents revolutionary progress. For example, the treatment of superficial vascular diseases such as wine stains and rosacea, congenital pigmented diseases such as nevus of Ota and freckle, the treatment of senile plaque and partial acquired pigmentation, and the elimination of artificial tattoos or superficial traumatic tattoos, laser has become the first choice in the above fields. Therefore, plastic surgeons need to master these new treatment methods more, so as to surpass the conventional surgical methods such as skin grafting and provide more ideal treatment for patients.
The application of laser technology in medicine, in addition to the above-mentioned medicine, has made new achievements and developments in the treatment of gallstones, orthopedics, gynecology, digestive tract and laser sterilization. In addition, laser devices and all kinds of laser-specific or multi-purpose medical equipment are also developing rapidly. Coupled with the promotion of world economic integration in the future, researchers from all over the world will cooperate with doctors to innovate. It can be believed that under the greater demand of human beings for laser medicine, a laser medicine that can cure diseases and save people is in the ascendant and developing vigorously.
