Technical Field

The invention relates to the technical field of medical science and beauty, in particular to a semiconductor laser scanning unhairing system and a semiconductor laser scanning unhairing method.

Background

Laser medical cosmetology is an important branch of medicine and is developing at a rapid pace. Laser depilation also becomes an important component of laser medical cosmetology, and the semiconductor laser depilation therapeutic apparatus is a main therapeutic apparatus that can realize human depilation at present, can reach permanent and painless depilation, and safe, no trace, convenient. Laser pulses with proper wavelength range and energy are emitted to generate heat action so as to destroy hair follicles, and the aim of laser depilation is achieved.

Scanning galvanometer technology is gradually widely applied in various industries, and is partially applied in the medical and cosmetic fields, but is not applied in the laser depilation field. The scanning galvanometer is composed of a scanning reflecting mirror, a swing motor, a position sensor, a driving circuit, a servo controller and the like, and is a high-precision and high-speed position follow-up control system. The scanning galvanometer is utilized to change the laser propagation direction, the semiconductor laser forms linear light spots after collimation, and the light beams form surface light spots spliced by the linear light spots on the surface of the skin under the high-speed reciprocating swing of the scanning galvanometer. Because the motion frequency of the scanning galvanometer is fast, uniform laser spots can be formed in effective time. The same treatment effect as that of the traditional multi-semiconductor laser depilation with uniform light spots is achieved.

At present, the laser depilation mainly adopts a semiconductor laser, and the power of the semiconductor laser is mainly 300W, 500W, 600W, 1200W and 2400W. The high-power laser adopts a multi-bar stacked array form, and the main structural components of the existing device are shown in fig. 5:

a system host: the system mainly comprises a display system, a control system, a power supply, a sensor, a cooling water circulation system and a filtering system. The display system mainly interacts with a user, sets parameters and displays an alarm. The control system mainly controls the sensor parameters and the laser power supply. The power supply mainly comprises a laser power supply, a water pump power supply, a control panel power supply, a refrigerator power supply and the like. The sensor mainly detects rivers, temperature and quality of water and is used for protecting the laser instrument. The cooling water circulation system mainly provides cooling circulating water for the laser and comprises a water tank, a water pump and a refrigerator. The filter system is mainly used for protecting the laser, and a PP cotton filter element and ion exchange resin are selected and matched according to different lasers.

The treatment handle: the device mainly comprises a semiconductor laser, a water cooling structure, an optical waveguide, a refrigerating head and a TEC refrigerating piece. The semiconductor laser (stacked array) mainly emits laser pulses with proper wavelength ranges (808 nm, 755nm and 1064 nm) and energy to generate heat action so as to destroy hair follicles and achieve the aim of laser depilation. The water cooling structure mainly provides water cooling heat dissipation for the semiconductor laser (stacked array) and the TEC refrigeration piece. The optical waveguide functions to homogenize the semiconductor laser light, making the laser light reaching the skin uniform. The refrigerating head is mainly used for cooling the skin, reducing the pain of a user and improving the user experience.

The disadvantages are that: the power of the high-power semiconductor laser is 300-2400W, so that potential safety hazards exist; the radiation generated by the laser device is harmful to the human body, especially the eyes, so that radiation-proof spectacles have to be worn before the machine is used. The higher the power is, the greater the potential safety hazard is, and the higher the laser power is, the greater the heat generation is, and the system must adopt a refrigerator with higher power;

the treatment handle has a complex structure; because the semiconductor laser must be too high, the minimum power is 300W at present, heat must be taken away through a water path, and meanwhile, the refrigeration TEC refrigeration module needs to dissipate heat. The handle must have a cooling water circulation structure. Meanwhile, an optical shaping part (optical waveguide) is also arranged, so that the structure of the handle is complex and heavy.
