Laser dot matrix method and laser dot matrix system for skin therapy

Abstract

The invention discloses a laser dot matrix method and a laser dot matrix system for skin therapy. The high-power semiconductor laser device dot matrix system for the skin therapy comprises a semiconductor laser device, an optical fiber patch cord, a supporting part and a focusing part, wherein the optical fiber patch cord is arranged at the output end of the semiconductor laser device; the supporting part is a hollow part; the output end of the optical fiber patch cord is arranged in a hollow part of the supporting part; the focusing part is used for focusing laser output by the optical fiber patch cord; the focusing part is arranged on a position, close to the output end of the optical fiber patch cord, of the hollow part of the supporting part. The supporting part and the focusing part are moved by a certain step length to form an extreme dot matrix to achieve a skin therapy purpose. The laser dot matrix system is simple in structure and low in cost.

Description

technical field [0001] The invention belongs to laser medical treatment, and relates to a high-power semiconductor laser lattice forming method and a high-power semiconductor laser system for skin treatment. Background technique [0002] As an important field of laser application, laser medical treatment develops very rapidly and gradually matures. semiconductor excitation [0003] Optical devices are especially suitable for the manufacture of medical equipment due to their small size, light weight, long life, low power consumption, and wide wavelength coverage. [0004] An important application of semiconductor lasers in the field of beauty is skin reconstruction surgery for wrinkle removal and skin rejuvenation. The laser is absorbed by the water in the collagen tissue of the dermis, which produces a thermal effect, stimulates the regeneration and remodeling of collagen, and makes the skin smooth and tender, and restores its elasticity. In addition, laser can also be us...

Problems solved by technology

However, in this technical solution, multiple small lenses with different structures are required to form a cup-shaped scanning element, which has a complex structure and high cost.

[0008] Chinese patent "a device for generating laser point light source clusters (CN10348793A)", this patent discloses a technical solution for forming laser point light source clusters, this technical solution Through the diffraction principle of the micropores of the filter paper, the laser light source is incident on the quantitative filter paper to form a laser point light source cluster. This technical solution is suitable for lasers with low power. For lasers with tens of watts or even hundreds of watts, this kind of The technical solution is not applicable, but in laser medical treatment, the power of the laser light source ranges from tens of watts to thousands of watts

[0009] US patent "Dermatological device having a zoom lens system (US2008 / 0186591A1)" discloses a skin disease treatment device, which discloses the use of microlens arrays in this technical solution To realize the technical scheme of laser dot array, the energy dispersion of this technical scheme is relatively serious, and the energy density of a single point is low, which will eventually lead to low treatment efficiency
