Description

Technical Field

[0001] The utility model mainly relates to the technical field of medical beauty equipment, and particularly relates to a spray-cooled skin radiofrequency instrument. Background Art

[0002] At present, the equipment in the field of radiofrequency beauty uses radiofrequency energy to output radiofrequency energy to tissues below the epidermis, such as the dermis layer, fat layer, etc., so as to achieve the beauty effect. Among these equipment, there are invasive ones that will puncture the skin tissue, and there are also non-invasive ones. One cooling method used in non-invasive ones is natural cooling (including natural skin heat dissipation or applying heat-conducting substances), which is common in beauty institutions and household products. For the equipment of this method, if high energy is used, it is extremely easy to cause burns. To ensure safety, the temperature and energy are generally strictly restricted, resulting in a low temperature of the target tissue, making it difficult to achieve the treatment effect, leading to an extremely long required treatment time and very unstable effects.

[0003] There are also forced cooling methods used in the existing market, such as Peltier cooling, water cooling, liquid nitrogen cooling, etc., which are common in beauty institutions. These refrigeration measures greatly increase the complexity of the equipment. Among them, methods such as Peltier cooling and water cooling have high requirements for the control of heat distribution. Otherwise, it is very easy to cause burns due to uneven heat. At the same time, the increase in equipment complexity also increases the equipment volume. And the liquid nitrogen cooling equipment has very high requirements for the environment and instruments, and requires the ability to store, transport and use liquid nitrogen. Moreover, this kind of equipment has extremely high requirements for energy and refrigeration, poor safety, and is easy to cause frostbite, burns and pain, and requires pretreatment with anesthetic. On this basis, a spray-cooled skin radiofrequency instrument is proposed. Content of the Utility Model
