Description

A laser medical cosmetic device using focused light spots

technical field

The invention relates to a medical device, in particular to a laser medical cosmetic device utilizing focused light spots.

Background technique

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.

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.

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 or even caused scars.

At present, abroad, 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.

How to provide a safe and efficient skin cosmetic device is an urgent problem to be solved.

Contents of the invention

The technical problem to be solved by the present invention is to propose a safe, effective and portable skin cosmetic medical device in view of the disadvantages and problems existing in the skin medical cosmetic device in the prior art.

The technical solution adopted by the present invention to solve the technical problem is: a laser medical cosmetic device using focused spot, which is characterized in that it includes an optical filter, an aperture stop and a focusing element capable of forming a periodic array of light spots; the light source The emitted light passes through the filter to remove the stray light of unnecessary wavelengths in the light source; then passes through the aperture diaphragm and enters the focusing element, and then passes through the focusing element to form a periodic spot array to act on the human skin to achieve medical beauty.

The light source is a laser with a wavelength range of 1um-12um.

The shape of the optical filter can be various shapes as required, including a circle, a quadrangle, or a hexagon.

The focusing element can form a periodic light spot array, which can be composed of a micro-optical element, or a main micro-optical element and other auxiliary elements.

The periodic light spot array formed by the focusing element ranges from 20 to 1000.

The focal length f of the focusing element ranges from 5 mm to 100 mm.

The shape of the focusing element can be in various shapes as required, including circular, quadrangular, or hexagonal.

The optical filter, aperture diaphragm and focusing element are packaged in a unified package by packaging technology, and can also be packaged in two or three sections. Each section contains one or two components and is screwed together.

The material used for the above package is metal or alloy.

Compared with the prior art, the present invention has the following advantages:

(1) The medical cosmetology device of the present invention uses a focusing element to divide the laser beam into a focused spot array, that is, the energy of the laser beam is split, and the spot array is used to perform medical cosmetology, and the device does not need to directly contact the skin. The thermal effect of focused light spots destroys the collagen of the skin, allowing it to regenerate into new young skin;

(2) The focus spot size of the medical cosmetic device of the present invention is on the order of microns, and the spot only destroys about 20% of the skin collagen tissue in the treated area, and the skin tissue of the rest is not destroyed, so the destroyed collagen can be quickly Growth into new youthful collagen, skin regeneration of the entire treatment area can be completed through multiple treatments;

(3) The medical cosmetic device of the present invention can produce tens to hundreds of independent focusing spot arrays by using the focusing element of the periodic light spot array, which improves the efficiency and efficiency of the device compared with the existing single-point laser scanning technology. Practical applicability;

(4) The medical cosmetic device of the present invention has simple structure and low cost, can meet the needs of small hospitals and even individual families, and is easy to popularize.

(5) The medical cosmetic device of the present invention is non-contact with the skin during actual treatment, which can avoid damaging the skin or causing scars.
