Description
Technical Field
The utility model belongs to the technical field of laser medicine, concretely relates to laser treatment equipment for skin healing is assisted to laser.
Background
Scars are the general term for the morphological and histopathological changes of normal skin tissues caused by various skin injuries, and are the necessary products in the process of repairing human wounds. During the healing process of a wound, pathological scars can be formed by breaking the balance between anabolism and catabolism of collagen caused by various reasons. The scars bring psychological and physiological pains to patients from the aspects of appearance and body functions, and serious patients even influence the self-confidence of the patients, so that the patients can have inferior psychology. Therefore, scars are a focus of high clinical attention in both burn and wound, plastic surgery, and dermatology.
There are 2.34 hundred million surgical operations worldwide each year. Regardless of the technique or material used, these surgical procedures invariably result in various degrees of aesthetic scarring for the patient. A number of factors (specific anatomical location, genetic predisposition, age, blood supply, infection, sun exposure, etc.) have been shown to potentially increase the risk of abnormal scar formation, even after minor surgery. Especially for non-caucasian human skin types, the risk of known hypertrophic and cicatricial diseases is very high. According to literature, 10-70% of surgical interventions result in hypertrophic scars. In order to reduce the aesthetic impact of surgical scars, a number of different strategies have been identified, such as silicone dressings, pressure therapy and compression devices.
Clinical studies have shown that lasers can be used immediately after surgery to reduce the appearance of scarring. Laser-Assisted Skin Healing (LASH) techniques result in elevated Skin temperatures, altering the wound Healing process. Guy Magalon et al performed a prospective comparative clinical trial using a 810nm semiconductor laser system to irradiate the laser immediately after the skin is sutured, achieving the effect of accelerating and improving the healing process of the surgical scar. This laser was only used for Fitzpatrick grading type I-IV skin patients, since the 810nm wavelength is readily absorbed by melanin.
Studies with skin grafts and subsequent studies with healthy volunteer subjects showed that 1210nm wavelength is the most appropriate wavelength in the index HSP7 (heat shock protein 70) and that it is poorly absorbed by melanin, thus allowing it to be used in patients of all skin types, including Fitzpatrick graded types V and VI.
In the existing laser treatment equipment, the stability of a power supply has a crucial influence on the output of laser, so that the stability of the output wavelength of the laser is often poor due to the fluctuation of an input power supply of the existing laser equipment, and in order to solve the problems, the laser in the prior art generally adopts constant current drive, and provides active control for driving current through current sampling feedback, but the instability of a voltage reference and the precision deviation of a sampling resistor can influence the stability of the output current; moreover, as the laser power is larger, the heat dissipation heat flux density is higher and higher (for example, the total power of a single high-power solid-state laser is typically tens of watts to hundreds of watts, and the contact area is small, so the heat flux density is large, and reaches the magnitude of hundreds of watts to thousands of watts per square centimeter), while the conventional air cooling and other methods have difficulty in achieving the requirement of cooling the high-power solid-state laser, which causes serious heating of the laser during long-time operation, deviation of laser frequency generated by the laser, difficulty in homogenizing light beams, and even burnout of the laser, so the heat dissipation problem has become one of the major bottlenecks limiting the development of the high-power solid-state laser. In order to solve the problems, a water flow circulation refrigeration system is generally adopted in the prior art, the water flow circulation system needs long pipelines, the water quantity of a water tank needs to be relatively large, the power consumed by water flow transmission and heat exchange is large, the whole refrigeration system occupies a large amount of space, and the refrigeration system is inconvenient to use in practice.
