Laser lipolysis system coupling laser lipolysis, skin surface temperature measurement and spray cooling

Abstract

The invention discloses a laser lipolysis system coupling laser lipolysis, skin surface temperature measurement and spray cooling. Laser non-invasive external lipolysis, refrigerant spray cooling based skin cold protection and infrared skin temperature measurement are combined to form a treatment system, fat layer thickness is obtained by back calculation according to measured skin surface temperature, and refrigerant spray cooling parameters and laser parameters required by lipolysis are calculated according to the fat layer thickness; meanwhile, the skin surface temperature can be monitoredin real time, and temperatures of an epidermal layer, a corium layer and a fat layer are calculated. By means of regulation and control for laser parameters and the refrigerant spray cooling parameters as well as real-time monitoring, the temperature of the fat layer is controlled in a lipolysis working range, and heat injury of the epidermal layer and the corium layer is avoided.

Description

technical field [0001] The invention relates to the field of laser biomedical engineering medical devices, in particular to a precise and intelligent non-invasive fat-melting device that combines laser fat-melting in the treatment area, skin surface temperature measurement and spray cooling during the laser fat-melting process. Background technique [0002] Laser lipolysis is a method of fat reduction that uses laser energy to act on fat cells, and ablate the fat cells through the photothermal effect or light modulation effect of the laser. The current non-invasive external laser lipolysis usually has two wavelength ranges. One is to use the laser beam with a wavelength of 630-680nm to directly irradiate the local skin, and act on the fat tissue through the intact skin to ablate the fat cells. Treatment usually uses 10-17mW laser energy for about 30 minutes. Multiple treatments can reduce the circumference of the waist and buttocks by about 8-9 cm. The other is to use 1060n...

AI Technical Summary

Problems solved by technology

[0006] 2. Physicians have high requirements for operation level, high operation cost, long operation time and many times

[0007] 3. The dosage of laser mainly depends on clinical data and doctor’s experience, and there are few quantitative studies on the relationship between laser dosage and fat mass

[0008] 4. Complications such as skin burns may occur in laser lipolysis surgery. The measurement of skin surface temperature is mostly judged by the doctor touching the skin surface with his hands, which is easy to misjudge and has high requirements for doctors.

[0011] 2. Fat and water in adipose tissue have high absorption of 1060nm wavelength laser, which is not conducive to the absorption of laser energy by fat

However, the current laser treatment of port wine stains uses millisecond-level continuous spraying. If the continuous spraying time is too short, the cooling capacity in the depth direction is insufficient. If the continuous spraying time is too long, it will cause frostbite to the skin.
