Background
In the aspect of medical beauty treatment, the laser mainly adopts a light wave band which is beneficial to human bodies, has strong transmission capacity and high human tissue absorption rate, utilizes the selective photothermal effect and the focal photothermal effect of the laser on biological tissues, and enhances the activity of skin collagen by removing aged and atrophied epithelial cells, thereby increasing the elasticity of the skin, delaying the aging of the skin and playing the effects of beautifying and beautifying.
The dermal tissue is stimulated to generate new collagen tissue, and the stimulation to skin may be a gasified treatment method with wound or a non-gasified treatment method without obvious wound. The gasified treatment method with wound has obvious wound, needs longer time for recovery, and has larger treatment risk, and the single treatment effect is not ideal although the risk of the non-gasified treatment method is small. Until the invention of the lattice laser technology, the treatment is carried out by using the focal photothermal effect, thereby achieving a satisfactory curative effect to a certain extent, but greatly improving the safety and shortening the operation time and the postoperative recovery time.
The lattice laser technology is that tiny laser beams which are arranged in a lattice shape and emitted by a lattice laser treatment system irradiate a treatment area, and tiny small holes are drilled on skin and scars, so that a three-dimensional lattice-shaped gasification area is formed on the skin and the scars, a series of skin and scar reactions are caused, the skin and the scars are stimulated to carry out self-repairing, the effects of tightening the skin, tendering the skin, removing color spots and improving the scars are achieved, and the lattice laser technology is minimally invasive treatment between invasive and non-invasive. The clinical advantages of the traditional Chinese medicine are clear effect, small damage and short downtime, and are well received by doctors and patients.
In the laser medical and beauty industry, the application hand of laser treatment equipment is used for realizing the purpose of treating patient tissues by using a treatment handle, such as a honeycomb lattice handle, a DOE diffraction handle and the like. The hand tool disperses and focuses a large spot parallel beam input by a laser into a plurality of finer micro beams in a lattice shape. Thereby realizing more tiny wound surface treatment and more concentrated laser energy. In clinical application, the laser dot matrixes with different densities and intervals need to be selected according to the specific conditions of patients, so that the best data effect is achieved. The existing handpieces have the defects that the dot matrix density and the inter-dot distance are not adjustable, and different handpieces need to be replaced for adjustment; or adjust the structure complicacy, mostly change the interval between the lens light path through step motor to change the dot matrix distance, because optical lens piece has higher to the interval requirement, thereby has higher to the control accuracy requirement of motor, simultaneously because the joining of motor, the cost is higher on the one hand, causes the reliability reduction in addition.
