Description

A kind of skin wound diagnosis and treatment integrated probe and its implementation
Technical field
The present invention relates to skin diagnosis therapy fields, more particularly to a kind of skin wound diagnosis and treatment integrated probe and in fact Existing method.
Background technique
Skin is the important protective barrier of human body, and is the important component of body immune system, be human body area most Big organ.Skin continuity caused by any reasons such as operation, scald, burn, incised wound is destroyed and Deletional damage, if It is closed not in time, easily the acute and chronic infection of the generation surface of a wound and its corresponding complication, and may cause pathologic scar Generation.Therefore, it is always that doctor and patient are closed jointly that the quick healing of skin wound and the perfect of structure and function, which are repaired, The problem of heart.LED light has been shown to have Photobiomodulation, can accelerate the metabolism of irradiated site cell, promotes blood Liquid circulation, accelerates tissue trauma repair process.It has been favourably utilised for treatment chronic ulcer of skin etc..LED illumination creates skin The treatment repair in face depend on the optical parameters such as optical wavelength, flow, intensity, irradiation time, continuous wave or impulse wave and Treatment number of times clinically, treatment interval.Different lightwave grows the difference of the penetration capacity in skin histology, and usual wavelength is longer Penetration depth is deeper;Meanwhile the light of different wave length can be absorbed by different color bases in tissue, realize different therapeutic purposes and Effect.For example, clinically feux rouges (630nm~700nm) can penetrate the skin histology that skin histology reaches deep layer, it is usually used in treating Disease of sebaceous glands etc..Meanwhile the wavelength of 660nm can improve the microcirculation of the hematological system and lymphatic system of skin, stimulate cell Interior mitochondria activity, and it can reach the lamina reticularis of dermis of skin and make to play the skin fibroblasts in corium With stimulation generates collagen, accelerates wound repair.Blue light (400nm~470nm) penetration capacity is weaker, is usually used in treating position In the skin lesion of epidermis, still, 470nm blue light has apparent bactericidal effect, and can promote revascularization and tissue repair.In addition, After 595nm yellow light skin, has and accelerate blood circulation, activating cell stimulates the active effect of cell excitability, and promotes Collagen synthesis.Multi-wavelength's LED light combination irradiation generates different therapeutic effects to skin wound, also just studied application To promote the more preferable reparation of the surface of a wound.
Meanwhile skin wound reparation is a various kinds of cell and the complex process that cytoplasm participates in jointly.All ages and classes The ability of its skin wound reparation of the patient of different physical conditions is not quite similar.If can be supervised in time in LED illumination therapeutic process The state change for surveying cell and cytoplasm in skin epidermis and corium can adjust the light such as wavelength and the power for the treatment of light in time Parameter is learned to advantageously promote the quick and perfect reparation of skin wound.Develop rapidly in recent years based on tissue it is inherent at The nonlinear optics imaged skin mirror of the two-photon fluorescence excitation and second harmonic signal that divide can perform well in non-destructive monitoring Skin injury reparation.Keratin in skin epidermis and hair follicle, in the flavoprotein, NAD (P) H and skin corium in cell Elastic fibers etc. can generate self fluorescence signal, the collagen with non-centrosymmetric structure in skin corium by multiphoton excitation Albumen etc. can generate second harmonic signal, by these in skin histology in the autofluorescence of ingredient or harmonic signal Acquisition and imaging simultaneously can carry out lossless diagnosis and monitoring to skin histology under without additional compounds probe conditions.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of skin wound diagnosis and treatment integrated probe and its implementation, base In nonlinear optics imaging and LED array light exposure treatment, diagnosing and treating dual function is organically combined, is realized real-time Monitoring and in time adjustment LED light wavelength, photoradiation treatment dosage etc., improve the validity and accuracy for the treatment of, realize personalized Precisely treatment.
