Fig. 3 is the third structural representation of optic path of the present invention.

The specific embodiment

Fig. 1 is structural principle sketch map of the present invention, as shown in the figure: the laser therapeutic apparatus based on the OCT imaging system of present embodiment, comprise coherence chromatographic imaging (OCT)system 2 and lasertherapeutic system 1, the output laser optical path range of exposures of described lasertherapeutic system 1 is positioned at the range of exposures of the flashlight that the measurement of coherence tomography system props up; Both light paths can be coupled and form a light path, also can export by light path separately respectively, all can realize the two range of exposures overlaid or identical purpose.

In the present embodiment, comprise that also a flashlight that the measurement of the output laser of lasertherapeutic system 1 andcoherence tomography system 2 is propped up is coupled into theoutput coupling mirror 3 of same output light path, the flashlight that the output laser of described lasertherapeutic system 1 and the measurement ofcoherence tomography system 2 are propped up is output alternately; The flashlight that utilizesoutput coupling mirror 3 that the measurement of the output laser of lasertherapeutic system 1 andcoherence tomography system 2 is propped up is coupled into same light path, make that device structure of the present invention is simple, volume is little, reduce cost, and the two light path shares, make that tracking detects, treatment is more accurate, avoid occurring asynchronous and the inaccurate problem in treatment orientation; The flashlight that the output laser of laser therapeutic system and the measurement of coherence tomography system are propped up alternately output avoids the two to interfere with each other, generally control by automatic control system, control the emission of the two and close frequency, belong to general automation field, do not repeat them here.

In the present embodiment, flashlight and reflected light full impregnated that the output laser of 3 pairs of lasertherapeutic systems 1 of described output coupling mirror is all-trans and the measurement ofcoherence tomography system 2 is propped up, this output coupling mirror is the 45 setting; 45 refers to: the output laser of laser therapeutic system is 45 and is incident to output coupling mirror and total reflection, the flashlight that the measurement of coherence tomography system is propped up is 45 and is delivered to output coupling mirror and total transmissivity, and the two is gone the same way by the light path of output coupling mirror transmission and reflection.

In the present embodiment, the flashlight that the output laser of described lasertherapeutic system 1 and the measurement ofcoherence tomography system 2 are propped up is coupled into a branch of coaxial collimated beam by output coupling mirror and outputs tocondenser lens 6 behind collimating mirror collimation separately; As shown in the figure, thelaser alignment mirror 4 of the output laser of lasertherapeutic system 1 beforeoutput coupling mirror 3, the flashlight collimating mirror 5 of the flashlight that the measurement ofcoherence tomography system 2 is propped up beforeoutput coupling mirror 3.

In the present embodiment, also comprise thegalvanometer 12 for scanning, the flashlight that the measurement of the coherence tomography system that is set forth in 2 is propped up through collimation and aftergalvanometer 12 reflection and the output laser of lasertherapeutic system 1 be coupled into same output light path byoutput coupling mirror 3; Make the present invention when the treatment that is used for subcutaneous pathological tissues or beauty treatment, form sweep limits, with obtain comparatively accurately, information on a large scale; For the treatment in later stage is prepared.

When the present invention used, for treatment or the beauty treatment of subcutaneous pathological tissues, the flashlight that the output laser of described laser therapeutic system and the measurement of coherence tomography system are propped up focused on behind the line focus lens and shines lesion region or the beauty treatment zone that needs treatment; Described laser therapeutic apparatus based on the OCT imaging system can be doctor or cosmetologist's manual adjustments irradiation area, also the treatment head of therapeutic instrument can be placed on the electric platforms, by computer regulating and controlling irradiation area.

Fig. 2 is second kind of structural representation of optic path of the present invention; The difference of present embodiment and above-described embodiment only is: in the present embodiment, present embodiment comprisesendoscopic system 7, is not provided withgalvanometer 12; The fiber-optic transfer of the conduit of the output light path of describedoutput coupling mirror 3 by being positioned atendoscopic system 7; As shown in the figure, output light path inputs in the conduit ofendoscopic system 7 byoptical fiber 8; Utilize endoscope to realize detecting and treating for human internal organs, as intestinal, stomach etc.; Theendoscopic system 7 general flexible catheter formula endoscopic systems that adopt, structure and the operation of this endoscopic system and conduit thereof belong to prior art, do not repeat them here.

Fig. 3 is the third structural representation of optic path of the present invention; In the present embodiment, compriseendoscopic system 7 equally, but do not comprisegalvanometer 12 andoutput coupling mirror 3, after focusing on respectively, the flashlight that the output laser of lasertherapeutic system 1 and the measurement ofcoherence tomography system 2 are propped up is coupled into the interior same optical fiber of conduit ofendoscopic system 7, as shown in the figure, the present invention utilizes 2 * 1 fiber couplers 13 to realize above-mentioned purpose, the output laser of lasertherapeutic system 1 collimates also throughlaser alignment mirror 4 and enters 2 * 1 fiber couplers 13 byoptical fiber 10 after theline focus lens 4a focusing, and the flashlight that the measurement ofcoherence tomography system 2 is propped up enters 2 * 1 fiber couplers 13 byoptical fiber 11 after flashlight collimating mirror 5 collimations and line focus lens 5a focusing; The flashlight that the output laser of described lasertherapeutic system 1 and the measurement ofcoherence tomography system 2 are propped up alternately or is synchronously exported; Do not adopt output coupling mirror, still can realize goal of the invention.

Certainly, can also adopt the structure that has following difference with the third structure:

Can compriseendoscopic system 7 equally, after focusing on respectively, passes through the flashlight that the output laser of lasertherapeutic system 1 and the measurement ofcoherence tomography system 2 are propped up fiber-optic transfer separately respectively, the output laser that is lasertherapeutic system 1 is exported by independent optical fiber, and the flashlight that the measurement ofchromatographic imaging system 2 is propped up is by another independent optical fiber output; Two optical fiber all are positioned at the conduit ofendoscopic system 7; Adopt separately independently that optical fiber transmits, the inessential trouble that can avoid maloperation to bring, and an optical fiber breaks down therein, and still tool has certain effect.

Explanation is at last, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although with reference to preferred embodiment the present invention is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technical scheme of the present invention, and not breaking away from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
