Description

Laser therapeutic system
Technical field
The present invention relates to a kind of laser therapeutic system, especially a kind of cutting hemoglobin tissue of both can effectively having vaporized also has good solidified structure and haemostatic effect, and clearly indicates the laser therapeutic system of therapeutic goal.
Background technology
Laser has high brightness and high directivity, is easy to control and phtotpolymerizable Jiao, and laser can also import body cavity with fiber-optic transfer.Laser also has characteristics such as monochromaticity and coherence, makes laser obtain extensive use in medical science.Wherein most of medical applications are that the heat effect of utilizing laser energy is solidified, carbonization and vaporization tissue, when injected organism tissue is melted or cut and reach the purpose of treatment.
The green laser of 532 nanometers relatively is fit to melt or cut the hemoglobin tissue.Because the green laser penetration tissue depth of 532 nanometers is shallow, only there are 800 microns, absorptance to water is little, the cutting of can in water environment, vaporizing, and contain 80% the moisture of having an appointment in the tissue, so the green cut hemoglobin function of organization of 532 nanometers is strong, can be absorbed by the hemoglobin tissue selectivity, only the green laser of acousto-optic Q modulation 532 nanometers with tens of watts of power just makes the hemoglobin tissue vaporization when cutting, human body is cut open, cutting speed is fast, and wound is little, and wound heals easily.Again because the green laser of 532 nanometers belongs to four-level system, system parameter is influenced by external condition to change to compare with other laser less, and stable work in work can also import body cavity by the ordinary optic fibre transmission, loss is low, uses so be fit to very much medical treatment cutting hemoglobin tissue.
Because water is little to 1.06 microns laser absorption rate, therefore 1.06 microns laser have solidified structure and hemostatic capability preferably.Go deep into the dark advantage of when injected organism tissue 1.06 the Nd:YAG laser of micron wave length has, the degree of depth of infiltrating when injected organism tissue can reach 10mm, solidifies hemoglobin tissue and hemostatic effect preferably so have.Therefore use the Nd:YAG laser of 1.06 micron wave lengths to undergo surgery and treat.
There is the green laser of frequency multiplication of wavelength 2.94 μ m Er:YAG, 10.6 μ m CO2,2.09 μ mHo:YAG and wavelength 1.06 μ m Nd:YAG in present medical laser system.But these laser systems are single wavelength or multi-wavelength no matter, all is the simple modes of operation of pulse running mostly.And containing multiple compositions such as hemoglobin and water in the human body, heterogeneity has characterized absorption the holding property of human body to laser to the absorption of different wave length laser.The composition high, laser to the laser energy absorption rate just can moment just with tissue vaporization, have good cutting.Therefore can be used for surgical cut vaporization when injected organism tissue, but defective is the hemostatic function deficiency, carbonization is serious and wound is very big.
And Er:YAG laser can not transmit by silica fibre, can only transmit with special optical fiber, yet the price of special optical fiber is very expensive, and medical expense is very high.And Ho:YAG laser strict to operating temperature, lasing efficiency is just very low when being higher than 5 ℃ of operating temperatures, and output reduces so that can not use.CO2 laser belongs to gas laser again, and the life-span is shorter than solid state laser, and beam quality is good not as Solid State Laser.
Existing a kind of green laser therapeutic system that is used for the treatment of is a lamp pump Nd:YAG quasi-continuous laser.It is made up of quasi-continuous 532nm green glow and 1.06 μ m infrared lights.But at first, because the solid state laser of lamp pump just contains the defective of many lamp pump lasers inevitably.Big such as system bulk, service life is short, needs huge power supply and control section.And the efficiency of laser of lamp pumping is low, and slope efficiency is on average between 1%-3%, and beam quality is relatively poor relatively, the system reliability instability.And the laser therapeutic apparatus that uses as medical treatment must have the reliable quality assurance, just can reach satisfactory therapeutic effects, so the laser system of this lamp pump must face a lot of difficulties in clinical use.
Secondly, this system is the 532nm green glow and the 1.06 μ m infrared light laser systems of quasi continuous operation.This is the output laser that is obtained under the situation that fundamental frequency light does not have to turn-off by frequency double laser, just determined frequency doubled light 532nm green glow to have identical oscillating characteristic with fundamental frequency light 1.06 μ m laser, promptly the both is the very high laser instrument of peak power of quasi continuous operation.Fig. 1 represents the pulse envelope of quasi-continuous 532nm green glow and quasi-continuous fundamental frequency light 1.06 μ m laser, and solid line is represented the pulse envelope of 1.06 μ m laser among the figure, and dotted line is represented the pulse envelope of quasi-continuous 532nm green glow, and it is the Pt curve of power P and time t.Having determined that by the generation mechanism of this laser instrument both laser generation parameters such as pulsewidth, cycle, modulating frequency and peak power are identical, also is simultaneously substantially on the time, has only the wavelength difference, and t=0 represents among the figure, and two enveloping surfaces overlap.Therefore, in medical treatment, the pulse that both peak powers are very strong can be cut human body effectively, but this form turns round to such an extent that laser instrument hemostatic effect is too poor, amount of bleeding is very big in the operation, and the wound healing difficulty has directly increased patient's the misery and the difficulty of operation.Thus, there is the hemostatic capability defect of insufficient in the laser instrument of pulse.And the raising of green glow power has also improved pump power, the corresponding system cost that improved.
