Detailed description of the invention
As shown in Figure 2 and Figure 4, fiber coupling module, TEC power supply, water-cooling system are all built in the equipment of rear end the overall structure of the present embodiment, by protective casing, optical fiber, TEC power line, water pipe are drawn, and are connected with the laser medicine hands tool of front end.
One, light source
Adopt fiber coupling module as treatment light source, fiber coupling module has the advantages such as hot spot uniformity is good, pliability is good, and fiber coupling module is separated with laser medicine hands tool in such a system, so laser medicine hands tool has features such as volume is little, lightweight, anti-condensation.
Two, water circulation system
Hands tool built-in circulating water structure part structure, is made up of water inlet, water outlet and water tank, and uses O-ring to seal, and the object of cisten mechanism is TEC heat radiation, and this structure has that radiating efficiency is high, the feature of good stability, as shown in Figure 7.
Three, refrigeration system
The refrigeration components and parts adopted in refrigeration system are annular TEC, and as shown in Figure 8, the structure of this TEC is this device and designing specially, have that refrigerating efficiency is high, stability strong, the feature of good reliability.TEC is that the refrigeration head of front end freezes.The heat that TEC produces when freezing is dispelled the heat by the cisten mechanism of rear end, finally realize system stability, Effec-tive Function, concrete as Fig. 6, shown in 7: cooling circulating water through water tank be the hot-side heat dissipation of TEC, the cold junction of TEC is refrigeration head and fiber waveguide refrigeration, can ensure lower temperature, reducing the pain for the treatment of and producing when treating, the recirculated water of water tank can take away the heat that TEC hot junction produces in time simultaneously, enables the work of TEC efficient stable.
The operation principle of semiconductor cooler (TEC):
Semiconductor cooler, also known as TEC, connects two blocks of different metals with conductor, connects unidirectional current, then a contact place temperature reduces, and another contact place temperature raises.If by reverse power connection, then the temperature inverse variation at contact place.This phenomenon is called peltier effect, also known as heat-electrical effect.Heat-the electrical effect of simple metal is very little, if replace metal with a N-type semiconductor and a P-type semiconductor, effect is just much bigger.After switching on power, produce electron-hole pair near upper contact, interior energy reduces, and temperature reduces, and outwardly absorbs heat, is called cold junction.The other end is because of electron-hole pair compound, and interior energy increases, and temperature raises, and to environment heat release, is called hot junction.The temperature difference that a pair semicondcutor thermoelements produces and cold all very little, practical semiconductor cooler is by much forming through in parallel, tandem compound thermoelement, also claiming thermoelectric pile.Single stage thermoelectric heap can obtain the temperature difference of about 60 DEG C, and namely cold junction temperature can reach-10 ~-20 DEG C.Increasing thermoelectric pile progression can make the temperature difference at two ends strengthen.
Four, optical system
As shown in Figure 5, laser enters laser medicine hands tool by the conduction of light, is then finally exporting through the transmission of fiber waveguide and homogenize.
Optical system adopts one-part form optical waveguide structure, makes hot spot homogenize more; And adopt cambered surface design in the position of contact skin, can be more smooth and easy when treating.
