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 protecting sleeve pipe optical fiber, TEC power line, water pipe to be 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 separates with laser medicine hands tool in such a system, so laser medicine hands has the features such as little, lightweight, the anti-condensation of volume.
Two, water circulation system
Hands has 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 purpose of cisten mechanism is to dispel the heat for TEC, and this structure has the feature of radiating efficiency height, 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 designs exclusively for this device, have that refrigerating efficiency height, stability is strong, the feature of good reliability. The refrigeration head that TEC is front end freezes. TEC produced heat when refrigeration is dispelled the heat by the cisten mechanism of rear end, finally realize system stability, Effec-tive Function, concrete such as Fig. 6, shown in 7: cooling circulating water is the hot-side heat dissipation of TEC through water tank, the cold end of TEC is refrigeration head and fiber waveguide refrigeration, ensure that relatively low temperature when treatment, reduces the produced pain for the treatment of, the recirculated water of water tank can take away heat produced by TEC hot junction in time simultaneously, enables the work of TEC efficient stable.
The operation principle of semiconductor cooler (TEC):
Semiconductor cooler, also known as TEC, connects metal two pieces different with conductor, connects unidirectional current, then a junction temperature reduces, and another junction temperature raises. If by reverse power connection, then the temperature inverse variation of junction. This phenomenon is called peltier effect, also known as thermo-electrically effect. The thermo-electrically effect of simple metal is only small, if replacing metal with a N-type semiconductor and a P-type semiconductor, effect is just much bigger. After switching on power, producing electron-hole pair near upper contact, interior energy reduces, and temperature reduces, and outwardly absorbs heat, is called cold end. 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. Produced by a pair semicondcutor thermoelements, the temperature difference and cold are all only small, and practical semiconductor cooler is by a lot of, thermoelement to be formed through in parallel, tandem compound, also referred to as thermoelectric pile. Single stage thermoelectric heap can obtain the temperature difference of about 60 DEG C, namely cold junction temperature up to-10～-20 DEG C.Increasing thermoelectric pile progression can make the temperature difference at two ends strengthen.
Four, optical system
As it is shown in figure 5, laser enters laser medicine hands tool by the conduction of light, then through the transmission of fiber waveguide with homogenize final output.
Optical system adopts one-part form optical waveguide structure, makes hot spot more homogenize; And adopt cambered surface design in the position of contact skin, can be more smooth and easy when treatment.
