Hand tool for treating chloasma

Abstract

The invention discloses a hand tool for treating chloasma. The hand tool comprises a first fitting, a second fitting and a metal shell, wherein the first fitting comprises a first hollow cylinder with two opened ends, threads are formed in the outer walls of the upper and lower ends of the first hollow cylinder, a convex lens and a concave lens are fixedly arranged in the first hollow cylinder, the convex lens is located above the concave lens, and a gap is formed between the convex lens and the concave lens; the second fitting comprises a second hollow cylinder with two opened ends, threads are formed in the outer wall of the second hollow cylinder, a first round disc is fixedly arranged in the second hollow cylinder, and a plurality of small convex lenses are arranged on the first round disc; and the metal shell is a hollow cylinder with two opened ends, and threads are formed in the inner wall of the metal shell. According to the hand tool for treating the chloasma, the laser beams with strong explosion capacity of big light spots are decomposed into needle tip-shaped small light spots with strong explosion capacity, so that the injury caused by strong laser to normal skin tissues is avoided, and the laser resistance of the skin is enhanced.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a hand tool for treating chloasma. Background technique [0002] Chloasma is an extremely difficult-to-treat hyperpigmentation disease, which can easily affect the physical and mental health of patients. Because the existing lasers have many disadvantages in the treatment of chloasma to a certain extent, such as excessive energy, it is very difficult to It is easy to cause the aggravation of chloasma, and if the energy is too light, it is easy to cause the treatment of chloasma to be ineffective. In order to solve the targeting of chloasma laser treatment and reduce the adverse consequences caused by over-weight or under-treatment, the special invention This tool for the treatment of chloasma. [0003] The existing ways of using optical equipment to treat chloasma are: 1. Intense pulsed light is to use the selective photothermal effect of light and the corresponding ...

Problems solved by technology

[0002] Melasma is an extremely difficult-to-treat hyperpigmentation disease, which can easily affect the physical and mental health of patients. Because the existing lasers have many disadvantages in the treatment of chloasma to a certain extent, such as excessive energy, it is very difficult to treat chloasma. It is easy to cause the aggravation of chloasma, and if the energy is too light, it is easy to cause the treatment of chloasma to be ineffective. This tool for the treatment of chloasma

[0003] The existing ways of using optical equipment to treat chloasma are: 1. Intense pulsed light is to use the selective photothermal effect of light and the corresponding biological stimulation to achieve the purpose of treating chloasma. The disadvantage is that it is difficult to control and easy to control. Blisters and scabs appear, and improper operation can easily aggravate chloasma, and it is difficult to disappear

2. Q-switched laser has a strong ability to blast pigments, and it is easy to cause excessive stimulation and aggravate chloasma

3. Drug therapy: External drug therapy can easily cause drug dependence, or destroy the existing skin barrier, and aggravate the influencing factors of chloasma; long-term oral drug use is also difficult to ensure that oral drugs will not cause any harm to the body

4. Although the latest picosecond laser has a stronger effect on pigment blasting and less damage, it is difficult to adjust the size of each spot with a "honeycomb" hand, and it is impossible to adjust the optical density of each "honeycomb" spot
