Description
Technical field
The invention belongs to the metrology and measurement field of selective spectral bright light medical science, be specifically related to a kind of intense pulsed light (intense pulsedlight, IPL) quality detecting system and the method for the treatment shaven head of photon therapy instrument, the quality inspection that is mainly used in the treatment shaven head of IPL photon therapy instrument such as photo instrument, photon delicate skin instrument is controlled.
Background technology
Developing rapidly mainly of selective spectral bright light medical domain has benefited from " selective light heat effect " theory, its implication is: according to the biological characteristics of different tissues, as long as select suitable wavelengths, energy, pulse duration, to guarantee that pathological tissues is effectively treated the while, avoid normal structure is on every side caused damage as far as possible.The therapeutic equipment that is used for the selective spectral bright light medical domain at present mainly contains laser and intense pulsed light.The treatment mechanism of IPL is similar to laser, also is according to the selective photothermolysis intreractive theory.
Any variation of caused laser and biological tissue all was called laser biological effects after laser and biological tissue interacted.The biological effect of laser is the theoretical basis that is applied to medical science.Usually the variation of laser is used for diagnosis, and the variation of biological tissue then is the theoretical basis of laser therapy.The power of laser biological effects was both relevant with the character of biological tissue, and was relevant with the performance of laser again.The mechanism of laser biological effects it is generally acknowledged heat effect, pressure effect, actinic effect and galvanomagnetic-effect.
Laser is to be converted into heat energy after light is absorbed by biological tissue to the heat effect of biological tissue, and the temperature of tissue is raise, and character changes.Laser can make the fine particle that is suspended in the solution to all the winds move with very big acceleration to the pressure action of biological tissue, makes tissue produce mechanical damage and destruction.Laser can cause that to the photochemical reaction of biological tissue enzyme, aminoacid, protein, nucleic acid isoreactivity change, the higher structure of molecule also has variation in various degree, thereby produces as biological effects such as bactericidal action, erythemal effect, pigmentation, vitamin D synthesize.Above-mentioned three kinds of effects are light form and function of organization generations with particle, and laser is again electromagnetic wave, and laser also acts on the form and the biological tissue of electromagnetic field.Electrostriction can take place in biological tissue under the effect of light, the electrostriction that light causes can produce ultrasound wave again, and cavitation effect of ultrasonic waves can make cell rupture or edema takes place.
The performance of laser mainly comprises wavelength, energy and pulse duration.At first to select to affact target tissue and by the wavelength of target tissue strong absorption.Because the penetration depth of laser in tissue is directly proportional with Wavelength of Laser, the size of laser penetration power should be at first considered in the selection of optical maser wavelength when therefore treating; diseased region is dark more; then required optical maser wavelength is long more; especially the pathological changes in corium deep must be selected long optical maser wavelength, otherwise laser action is less than diseased region.
Its less important selection can produce enough temperature on target tissue, make it destructive appropriate energy.Enough laser energies are the prerequisites that guarantees curative effect, and modern laser device all has powerful power.The energy density fibrous root of laser waits to determine according to character, shade, big or small thickness and the treatment reaction at that time of target tissue during practical clinical, should constantly debug and revise laser energy in the therapeutic process.As the low excessively curative effect of selecting, too high then tangible ulotic danger of not reaching of laser energy.
The pulse duration of last laser should be less than or equal to the thermal relaxation time of target tissue.Necessary long enough of the pulse duration of laser, the abundant destruction that just can cause target tissue, but heat conducting how much being directly proportional with the pulse duration, the time is long more, and hot injury's scope is big more.According to optical theory, as long as make the pulse duration of laser be less than or equal to the thermal relaxation time of target tissue, the hot injury that can not cause surrounding tissue just.
The principle of IPL photon therapy instrument treatment skin is that skin selectivity absorbing wavelength is the high power pulse photon of 560nm-1200nm, produces different photoproductionization, pyrolytic reaction.Wherein, short-wave band photon selectively acting is in subcutaneous pigment or vascular lesion tissue, makes that its pigment and vascular lesion tissue decompose, solidify, carbonization comes off, and reaches therapeutical effect; Long-wave band photon stimulation collagen and elastic fiber make collagen protein and elastic fiber rearrange and thicken, and reinvent skin elasticity.The depilation principle of IPL photon therapy instrument is the high power pulse photon that the melanin in the hair selectively absorbs 690nm-1200nm, melanin is mainly in the hair follicle stromal cell, in the hair growth process, be sent to the hair shaft part, melanin during follicular epithelium, hair papilla and hair are protruding is the abundantest, behind these melanin absorption luminous energy, make local temperature be elevated to 65-70 ℃, thereby destroy hair follicle, hinder and stop the growth of hair.
At present since IPL photon therapy instrument in the process of using, the check of instrument performance and quality generally realizes by clinical effectiveness.And manifesting of clinical effectiveness needs the cycle, and the information that the while clinical effectiveness shows is a kind of integrated information, i.e. the concentrated expression of physical property key element and the biological key element of skin that is applied.So the information that clinical effectiveness displays can not reflect directly whether the instrument parameters reaches designing requirement.A lot of home-made the said equipments, the effect that not only can not play treatment that has, on the contrary than original worse off cake, its basic reason is exactly not have perfect quality control system and detection means in process of production after finishing.
