Biological tissue different depth layer is to the backward scattered wave echo time delay and echo signal intensity of incident weak coherent light, by sweeping
Retouch and obtain sample two dimension or three-dimensional high-resolution heterogeneous microstructure, so as to obtain sample in the lossless tomography layer of body
Analyse image.OCT image technology need not add any developer, without ionisation effect and fluorescent effect, than traditional image technology
Security is higher, is referred to as " optical biopsy ".
Compared to x-ray imaging, ultrasonic imaging and nmr imaging technique, OCT Tomography technologies have higher
Resolution ratio, at present universal OCT Tomographies technology can reach 10 μm of rank resolution ratio, than X-ray and nuclear magnetic resonance
Imaging technique is higher by two magnitudes.The advantages of high-resolution, Non-Destructive Testing, causes OCT Tomographies technology in such as eye
The fields such as section, dept. of dermatology, dentistry and handicraft detection are widely used, and achieve gratifying effect.
Existing OCT layer scanning technologies all using near infrared light (such as 1300nm) as probe source, and near infrared light
The red blood cell in blood vessel can not be penetrated well, so the short time must be taken to hinder in cardiovascular field application OCT technology
The method such as clinopodium polycephalum or local douche blood vessel excludes the blood in blood vessel, is then scanned imaging.This detection method wind
Danger is larger, easily causes patient's myocardial ischemia, and complex operation, there is very high operation requirement to operator.By OCT technology
It is widely applied to angiogram, intraluminal tissue (such as lung) and checks field, improves the imaging matter of OCT Tomography technologies
Amount is crucial.
The OCT probe detected currently used for blood vessel, existing has lacking for air gap between scanning head and outer protective jacket
Fall into.The presence of air gap make it that the hot spot from probe outgoing easily produces distortion, becomes ellipse light spot, influences the convergence of light beam
Effect, so as to cause the decline of image quality.For the problem, patent CN201520036955.2 is taken in a kind of protection sleeve pipe
The method that wall is matched completely with probe body front end, though the problem of solving the air gap, due to matching completely, now protects
Between sleeve pipe and probe body have drive connection, and OCT probe in biopsy mainly using circumference circular scanning by the way of, this
It is required that the OCT protection sleeve pipes contacted with tissue can not carry out circumferential circulatory motion.Therefore, finding one kind can effectively improve
The method of OCT Tomography quality is significant.
Utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is that providing a kind of human body that is applied to opens tube chamber
The OCT probe in road, it can be solved when scanning imagery, because there is the air gap between probe body and external probes guard
And cause the defect of fogging image.
The purpose of this utility model is realized using following technical scheme：
A kind of OCT probe applied to human body open pipes cavity, including probe guard, probe body, oil-based liquid, metal
Coil, the probe shield tip and light-conductive optic fibre, the probe body and wire coil Matching installation, and wire coil is installed on probe originally
The rear end of body, the light-conductive optic fibre is fixed on inside probe body, and the probe shield tip is socketed on probe body, the probe
Guard is socketed on the probe shield tip and wire coil, and the oil-based liquid is filled in the probe shield tip and wire coil and protected with probe
Between part.
Preferably, in addition to fixture, the fixture, which is used to probe body and probe protecting the tip, fixes.It can be further
Solve the technical problem of the fixation of the probe shield tip and probe body.
Preferably, the probe guard is medical round end nylon elastic pipe.It can further solve the material of probe guard
Selection technical problem.
Preferably, the front end of the probe guard is hemispherical, and probe guard external diameter is less than or equal to 3mm.It can enter one
Step solves the technical problem of the selection of probe guard.
Preferably, the fixture is medical plastic fixture or medical stainless steel fixture.It is further solved
The technical problem of the selection of the material of fixture.
Preferably, the probe shield tip is the medical stainless steel probe shield tip.It further solves the material of the probe shield tip
Selection technical problem.
Preferably, the oil-based liquid has identical refractive index with probe guard.It further solves guide-lighting skew
Technical problem.
Preferably, in addition to linking stator, the linking stator be used for wire coil is fixed with light-conductive optic fibre.It can enter
One step solves the technical problem of the fixation of wire coil and light-conductive optic fibre.
Compared with prior art, the beneficial effects of the utility model are：
The utility model effectively compensate for by filling oil-based liquid between OCT external probes guard and probe body
Scanning imaging technology is peeped in OCT when the complicated human body open pipes cavity of human body is scanned, because of probe body and external probes shield
There is air gap between part and cause the defect of fogging image, optimize imaging effect.
