Description
Technical field
The invention belongs to technical field of medical instruments, specifically, particularly a kind of radio frequency that adopts is as the instrument for treating acne of energy source.
Background technology
Acne is that a kind of chronic inflammatory skin of pilosebaceous unit is sick, is mainly apt to occur in teenager, to teen-age psychology and social influence very large, but often can naturally alleviate or fully recover after adolescence.Clinical manifestation is to be apt to occur in the pleomorphism skin lesion such as acne, pimple, pustule, tuberosity of face for feature.In 11 ~ 30 years old adolescence, incidence of acne is 80%, 12 ~ 24 years old up to 85%, within 25 ~ 34 years old, be 80%.
The factors such as the generation of acne is main and hypersteatosis, pilosebaceous duct block, bacteriological infection and inflammatory reaction are closely related.After adolescing, in human body, the level of androgen particularly testosterone raises rapidly, promotes that sebaceous gland is grown and produces a large amount of sebum.The dyskeratosis of pilosebaceous duct causes catheter blockage, dyssebacia simultaneously, forms horn plug.Multiple-microorganism especially propionibacterium acnes amount reproduction in hair follicle, the lipase decomposition sebum that propionibacterium acnes produces generates free fatty, chemotactic inflammatory cell and medium simultaneously, final induction also exacerbate inflammation reaction.
The Therapeutic Method of acne is a lot, and common Drug therapy has oral isotretinoin, oral antibiotic, oral glucocorticoid etc., and these medicines are large to normal organ side effect.And phototherapy only acts on skin, without any side effects to other organs.In the phototherapy product of Acne treatment, have near infrared light, mid-infrared light, the modes such as radio frequency, based on the acne treatment mode of heat effect effect, add hot injury to sebaceous gland.But in these products, because sebaceous gland and normal epidermis absorbance do not have the difference of significance, can cause there is pain in therapeutic process, the generation of Epidermal necrosis or cicatrix to the dosage of sebaceous gland damage.In pyogenic acne treatment, and the treatment of traditional phototherapy apparatus adopts manual type to needle the acne of suppurating, and allows pus flow out, then treats.This method improves cure rate to a certain extent, but has the risk of reporting to the leadship after accomplishing a task and infecting simultaneously.
The physiotherapy of acne mainly divides two kinds: one directly acts on propionibacterium acnes, and one directly acts on sebaceous gland.The therapeutic modality of effect propionibacterium acnes, the metabolite porphyrin being penetrated propionibacterium acnes by illumination produces singlet oxygen and free radical, makes propionibacterium acnes inactivation and reaches the object for the treatment of; And act on the therapeutic modality of sebaceous gland, be mainly the temperature changing acne spots sebaceous gland and treat.
Adopt the physiotherapy for the treatment of sebaceous gland, concrete has IPL, 1320nm laser, 1450nm laser, 1540nm laser, near infrared light, radio frequency etc.The mechanism of heat effect, carries out heating to destroy propionibacterium acnes to sebaceous gland, and the required temperature of target tissue is at about 70 DEG C, and wider scope is the 60-80 DEG C of effective Acne treatment of ability.Because the absorbance of sebaceous gland for energy source is compared with epidermis, the difference of significance, does not cause the temperature of whole skin area all can reach 60-70 degree Celsius, causes epidermis impaired.
According to acne lesions character and the order of severity, acne is divided into 4 grades: 1 grade clinically: only have acne; 2 grades: except acne, also have some inflamed papules; 3 grades: except acne, also have more inflamed papules or pustule; 4 grades: apart from outside acne, inflamed papules and pustule, go back nodosity, cyst or cicatrix.In 3 grades and 4 grades of acnes, all pustulate existence, this kind of acne, easy recurrent exerbation, gets rid of pus and externally to treat again, clinically significance improve curative effect.Eliminating for pus is external, be mainly needle point in the market and puncture the mode chosen, but this mode easily causes repeated infection, and doctor's workload significantly increases.Another kind method is, adopt the mode of vac sorb that pustule is inhaled broken, and pus is adsorbed skin, adopt in this way, treatment time is quick, and avoids the cross infection risk in evacuation of pus process.
There is the phototherapy product treatment pustular acne of two employing vac sorb in the market, as the Isolaz of Acleara and the solta company of palomar, but adsorb after before treatment needing acne to needle, in addition the treatment energy source of this two product is IPL intense pulsed light respectively, epidermis and sebaceous gland are not obvious for the light selective absorbing difference of these wave bands, cause therapeutic process mesocuticle temperature very high, and sebaceous gland spot temperature does not reach the effect destroying propionibacterium acnes, cause therapeutic effect not good.Meanwhile, the skin rdativery sensitive of acne happening part, epidermis very easily damages.This two product all can only be used for the treatment of slight and moderate acne, and namely 1,2,3 grades of acnes.
