Description
Invention field
This application involves the light processing being applied on human skin tissue, more particularly in intense pulsed light device it is sharp
With the light processing of selective bandpass optical filter.
Background of invention
Light ray radiation is the known way for skin disease disorder processing.In order to obtain clinical effectiveness in skin, irradiate
Luminous energy be preferably absorbed in skin.
Light absorption in skin is dominated by three kinds of endogenous chromophories: water, melanin and hemoglobin.Optical wavelength or wavelength
Correctly matching between spectrum and target chromophore may cause optical energy absorption, may be by one or more photo-thermal, light
Chemistry or photomechanical effect bring clinical effectiveness.When luminous energy irradiates on the skin, light scattering effect may influence light and wear
The depth organized thoroughly.Since the concentration of collagenous fibres in corium is higher, this effect (if any) is in the dermis than in table
It is more dominant in skin.In general, the wavelength of scattered quantum and light is inversely proportional until the mid infrared region of luminous energy.As Anderson and
" selective light thermal decomposition: the carrying out accurate microsurgery by the selective absorbing of impulse radiation " of Parrish is mentioned
And, Science, April 29 nineteen eighty-three；220 (4596): 524-7, as described above, by selecting wavelength appropriate to appropriate
Chromophore, may be implemented selective laser treatment, by apply energy pulse be shorter than or equal to target chromophore thermal relaxation
Time, and the energy by being higher than threshold value to destination organization delivering.Different various laser and intense pulsed light (IPL) device make
The optical treatment of wide scope is provided with these principles for skin disease.
Polychrome of the IPL device transmitting in about 400nm to the about spectral region of Isosorbide-5-Nitrae 00nm, incoherent and non-collimated light,
And usually with the delivering of various pulse durations.Therefore, the selectivity of IPL is lower, because can aim in the range not
Same chromophore.A kind of selection for improving the selectivity for the luminous energy that IPL is generated is using filter.In the transmitting light of IPL device
The lower end of spectrum uses cut-off filter, and uses incision filter in the upper end of emission spectrum.This filter can improve
Processing selectivity reduces parasitic wavelength, this may make patient be in danger, such as ultraviolet light or increased whole heating,
Such as there are infrared ingredients in the light emitted.Common medical IPL cut-off filter include 550,560,570,590,
615,645,695,755 and 780nm filter.Cut-off filter and incision filter can be used together to create so-called band
Bandpass filter.
Bandpass filter is provided by some suppliers (for example, Alma Lasers etc.), for example, providing
The narrow spectrum processing based on IPL within the scope of 500nm-600nm, for medical needle to the vascular lesion of larger blood vessel.In 550nm-
Another narrow-band pass filter is provided in the range of 600nm and is used for skin regeneration.One of the problem of this filter, is, is filtering
In photoreduction process, they also remove the partial optical energy generated by light source, and light source is IPL light source.Therefore, meet to pass through
Above-mentioned threshold energy requires to generate clinical effectiveness, can only remove limited amount spectrum.
In laser domain, vascular lesion is treated by aiming at the intravascular chromophore of oxyhemoglobin, oxygenated blood is red
Albumen has optical absorption peak at 418nm, 542nm and 577nm.The most common blood vessel laser is KTP, 532nm, pulsed dye
Laser (PDL) 585nm-595nm, alexandrite 755nm, diode laser 940-980nm and Nd:YAG 532 or 1,
064nm.PDL is considered as " main force " blood vessel laser.
As described above, IPL light source can be used for the treatment of vascular lesion, using including at least one in these absorption peaks
A filter and removal may cause the destructive UV wavelength and/or infrared wavelength of subsidiary thermal damage.Two companies,
Lumenis and Palomar provides this two band filter.For example, in blood vessel two band filter, shorter wavelength be used for compared with
Small superficial vein, and longer wavelength is used for biggish deeper blood vessel.
Pigment lesions are also by laser therapy, and by using laser, such as KTP (532nm), ruby (694nm) is emerald green
Jewel (755nm) etc., using the melanin in melanosome as target chromophore, using the various pulse durations, from millisecond
Grade start to picosecond.IPL can also be used for some pigmented lesions, such as pigmentation disease or solar lentigines mole.Equally, pass through choosing
The filter for generating appropriate spectral energy is selected, as long as the sufficiently wide energy density for making sufficient amount of spectrum reaches destination organization, IPL
The device of driving can be used for treating at least some pigmented lesions.However, spectrum is wider, different chromophories can be aimed at simultaneously
And selectivity can be reduced.In addition, in order to avoid cicatrization or the side effect of decoloration, it may be necessary to which short pulse targets to limit
The area or volume of any fuel factor in tissue.These short pulses can be within nanosecond or smaller range, and IPL is only in millisecond
Pulse is provided in range.
Various types of dermopathic flexibilities are treated on various types of skins using single source IPL in a device
Still it haves a great attraction.Therefore, it is necessary to a kind of more advanced systems to provide the processing based on IPL, have with higher
Selective or higher absorbance is imitated, its equivalent known laser wavelength designed for simulation is similar to.
