Device for medical beauty treatment of skin using binary raster focus

Abstract

The invention discloses a device for medical cosmetology of skin by utilizing the focusing of a binary grating, which comprises an optical filter, an aperture diaphragm, and a focusing element consisting of a binary Dammann grating and a Fourier transform lens, wherein the optical filter, the aperture diaphragm and the focusing element are orderly positioned on an emitting light path behind an external light source and are all placed perpendicularly to an optical axis; light emitted from the light source passes through the optical filter to remove parasitic light with unneeded wavelengths in the light source; then a light beam is adjusted through the aperture diaphragm; and then the adjusted light beam is incident to the focusing element and forms a periodical light spot array through the coaction of the binary Dammann grating and the Fourier transform lens to act on skin of a human body, thereby utilizing focusing light spots to realize the medical cosmetology. The device has the advantages that the device has simple structure and low cost, is convenient to carry, can meet the needs of small-sized hospitals even individuals and families, and is convenient to popularize.

Description

technical field [0001] The invention relates to a medical device, in particular to a device for skin medical beauty by using binary grating focusing. Background technique [0002] The use of light for medical treatment has been developed for many years, and a variety of medical devices using light have been developed to meet the requirements of patients. For example, at some point in the past, ultraviolet light has been used to treat psoriasis. There are also many people who use some light exposure in winter to reduce the body's seasonal response. [0003] The use of lasers in medicine was developed in the 1960s, when they were used as cutting tools in some surgical procedures; in the past few decades, lasers have been used to treat various skin problems, such as burns, psoriasis and acne, etc. ; and lasers are also playing an increasing role in the treatment of ophthalmic diseases, such as surgery for the treatment of myopia. [0004] In the past, skin rejuvenation and s...

AI Technical Summary

Problems solved by technology

[0004] In the past, skin rejuvenation and skin wrinkle removal could only be done through physical excision or grinding, which were difficult to control and easily damaged the skin and even caused scars, etc.

[0005] At present, in foreign countries, there are also devices that use lasers for medical cosmetology, such as for freckle removal, etc., but in the medical process, the cosmetology process of this device is carried out point by point, so the efficiency is relatively low
