Background technology
Laser is that the energy height of being launched by the working-laser material generation stimulated radiation that is in the population inversion state is concentrated, the light beam that directivity is extremely strong, monochromaticity is good, laser therapy aparatus is heat effect and the controllability of utilizing laser, to tissue shine, the optical, mechanical and electronic integration armarium of the operations such as cutting, ablation.utilize the selective thermal principle of absorption of tissue to laser, the color that laser therapy aparatus utilizes laser moment emission high-energy effectively to smash and dispel in pathological tissues is plain, the laser-induced blasting principle: laser gathers high-energy moment emission, the laser that makes fixed wave length at the utmost point in the short time (only 6ns) moment penetrate epidermis and arrive diseased tissue, smash rapidly corresponding color element, the very fast expansion moment explosion of being heated of corresponding pigment group is cracked, a part (substrate microstructure in) pigment group is fragmented into the fine particle that can be engulfed by macrophage in human body, after being digested by macrophage, finally by human body, by the lymphsystem circulation, got rid of external, the pigment of pathological tissues will be thin out until disappear gradually, the surrounding normal skin histology is because the laser that does not absorb fixed wave length does not form any damage.Thereby laser therapy aparatus extensive use on the beauty treatment projects such as the nevus of dispelling, speckle dispelling at present, but present laser therapy aparatus output energy is relatively low, the conversion efficiency of crystal is not high yet, when adopting laser therapy aparatus to treat, do not reach dark pigment cell or black/blue dyes granule of deep skin, treatment nevus fuscoceruleus ophthalmomaxillaris corium pigment pathological changes and dispel that dark color is tatooed, eyebrow tattooing, profiling eyelid line be not thorough yet.
YAG, be the abbreviation of yttrium-aluminium-garnet, and chemical formula is Y3Al5O12, is a kind of composite oxides that generated by Y2O3 and Al2O3 reaction, belongs to cubic system, has garnet structure.Garnet structure cell can be regarded the link net of dodecahedron, octahedral and tetrahedral as.
The Nd:YAG crystal is the most excellent laser crystal of present combination property.Optical maser wavelength 1064nm, be widely used in military affairs, industry and the industry such as medical.
Existing YAG laser therapy aparatus has plenty of monochromatic light road, single chamber work system, and the instrument energy can only reach 1064nm800mj and 532nm250mj, the traditional accent Q output that also has, and energy can only reach 1064nm400mj and 532nm100mj.
But the said equipment energy is relatively low, the purity of the conversion efficiency of crystal and 532nm wavelength is not good, do not reach dark pigment cell or black/blue dyes granule of deep skin, treatment nevus fuscoceruleus ophthalmomaxillaris corium pigment pathological changes and dispel that dark color is tatooed, eyebrow tattooing, profiling eyelid line be not thorough.
The YAG laser therapy aparatus is as the equipment for the treatment of nevus fuscoceruleus ophthalmomaxillaris corium pigment pathological changes, need energy can reach 1064nm1200mj and 532nm600mj assembling two-chamber double light path work system, adopt the single transverse mode lasers pattern of present state-of-the-art Gauss distribution, make the flat hat type output of laser, just can reach therapeutic effect.Therefore, existing YAG laser therapy aparatus need to be improved.
The utility model content
For the problems referred to above, main purpose of the present utility model be to provide a kind of by the irradiation to the human body pigment tissue to reach the YAG YAG laser photocoagulation treatment machine of therapeutic effect.
This utility model solves above-mentioned technical problem by following technical proposals: a kind of YAG YAG laser photocoagulation treatment machine, described YAG laser photocoagulation treatment machine comprises helium neon laser, Nd:YAG crystal, multiplier crystal and energy meter, between described helium neon laser and Nd:YAG crystal, diaphragm, total reflective mirror and dye is installed successively; Half anti-mirror is installed between Nd:YAG crystal and frequency-doubling crystal; In described energy meter, probe is installed.
In specific embodiment of the utility model, described Nd:YAG crystal one side is equipped with pumping lamp.
In specific embodiment of the utility model, be provided with working station indicator on described pumping lamp.
Positive progressive effect of the present utility model is: this utility model and existing similar YAG laser photocoagulation treatment machine compare, the YAG YAG laser photocoagulation treatment machine that this utility model provides, adopt the single transverse mode lasers pattern of present state-of-the-art Gauss distribution, make the flat hat type output of laser, energy can reach 1064nm1200mj and 532nm600mj, the purity of the conversion efficiency of crystal and 532nm wavelength, just can reach therapeutic effect.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Provide this utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
The technical solution of the utility model is as follows:
1064nm and the 532nm laser of the output of YAG laser therapy aparatus can be absorbed consumingly by melanin and hemoglobin, and its hetero-organization of human body is minimum to the absorption of laser.Therefore, this equipment can be dispelled pigment and the vascular tissue of pathological changes very effectively under the prerequisite of not damaging surrounding tissue, the selective thermal principle of absorption of the laser in medical science that Here it is, this machine output 1064nm Q-switch laser penetration capacity is strong, can reach dark pigment cell or black/blue dyes granule of deep skin, be applicable to treat nevus fuscoceruleus ophthalmomaxillaris corium pigment pathological changes and dispel that dark color is tatooed, eyebrow tattooing, profiling eyelid line etc.The 532nm laser energy is more consumingly by melanin absorption, thereby the laser penetration of this wavelength is more shallow, is mainly used in treating birthmark, coffee speckle, freckle, senile plaque and various pigmentation.
