Abstract

The invention relates to a superfine OCT (optical coherence tomography) imaging catheter. The superfine OCT imaging catheter comprises a socket, an injection section, a pivot tube and an intervention section. An optical fiber at the front end of the catheter is coated with an ultra-thin coating instead of a bourdon tube, so that the diameter of the catheter is reduced greatly, and the catheter can pass through capillary cavities of the whole body; the flexibility of the optical fiber is enhanced by the ultra-thin coating, so that optical fiber breakage is prevented when the catheter passes through circuitous focuses. The superfine OCT imaging catheter has a small diameter and can be applied to the capillary cavities and circuitous blood vessels of the whole body, so that the application range of the OCT imaging technology is greatly widened, and convenience is brought to interventional diagnosis and treatment of these parts.

Description

A kind of ultra-fine OCT image conduit

【Technical field】

The present invention relates to a kind of imaging catheter device, more particularly to a kind of ultra-fine OCT image conduit.

【Background technology】

Optical coherence tomography (Optical Coherence Tomography, abbreviation OCT) applies modern computer graphical Treatment, advanced optical technology is integrated with hypersensitive detector, develops into a kind of emerging fault imaging diagnostic techniques. The resolution ratio that OCT technology can reach is 10um, is one of Ink vessel transfusing imaging technique of highest resolution so far, is described as " internal histology microscope ".

The OCT equipment OCT conduits that need to arrange in pairs or groups are used in clinical practice, and the rotation of tube at one end connection OCT systems withdraws dress Put, other end intravasation is scanned, obtain the imaging features of vascular wall to carry out the diagnosis of disease.Because human vas are walked Shape is mostly bending, and has many tiny branch vessels, and existing OCT catheter products cannot be introduced into this due to oversized A little minute blood vessels, limit the intervention diagnosis and treatment of these diseased regions, limit the application of OCT technology.Therefore, reduce The diameter dimension of OCT conduits, makes it to apply in slightly larger blood vessel, moreover it is possible to be applied in more minute blood vessels, greatly The OCT image technology scope of application is widened, is that the intervention diagnosis and treatment at these positions offers convenience.To sum up, work out a kind of ultra-fine OCT conduits turn into currently to be needed badly.

【The content of the invention】

The problem to be solved in the present invention is to provide a kind of ultra-fine OCT image conduit, in being performed the operation for intervention, by reducing conduit The setting of diameter dimension and microthin coating, can apply in the capilary cavity of whole body, expand the scope of application, reduce operation wind Danger, beneficial to popularization and application.

To achieve the above object, the technical scheme taken of the present invention is:

A kind of ultra-fine OCT image conduit, including plug receptacle, enter and note section, maincenter pipe, intervene section;Conduit upper end is provided with maincenter pipe;Institute The maincenter pipe of stating respectively with plug receptacle, enter to note section with intervention section be connected;The plug receptacle is connected with OCT equipment;It is described enter note section with Injection device is connected;The intervention section outermost layer is outer protection tube, and the outer protection tube front end is provided with thread eye.

Further, the outer protection tube is made up of the good material of translucency.

Further, the optical fiber front end is prism.

Further, the prism has fixed light reflection angle.

Further, the intervention section center is optical fiber, optical fiber outer cladding bourdon tube, the optical fiber coating stretched out outside bourdon tube There is microthin coating.

Further, the outer protection tube that the optical fiber is stretched out at bourdon tube is provided with taper gradual change.

Compared with prior art, the present invention has the advantages that:

The 1st, a kind of ultra-fine OCT image conduit, the uncoated bourdon tube of optical fiber of catheter proximal end are provided, but coat microthin coating, greatly Conduit diameter size is reduced greatly, can be enabled the duct to by the capilary cavity of whole body.

2nd, microthin coating can play a part of transmitting torque, it is ensured that spin stabilization before and after optical fiber;Microthin coating increased light Fine flexibility so that prevent optical fiber from fractureing when conduit is by tortuous focus.

3rd, the outer protection tube that optical fiber is stretched out at bourdon tube is provided with taper gradual change, reduces stress concentration, prevents deformation of guide tube;Protect The concentricity of card optical fiber and conduit;Increase the smoothness of conduit.

【Brief description of the drawings】

Fig. 1 is the structural representation of ultra-fine OCT image conduit of the invention.

【Specific embodiment】

For technological means, creation characteristic, reached purpose and effect for making present invention realization are easy to understand, with reference to specific Implementation method, is expanded on further the present invention.

1- plug receptacles, 2- enters to note section, 3- maincenter pipes, and 4- intervention sections, 5- bourdon tubes, 6- taper gradual changes, 7- outer protection tubes, 8- surpasses Shallow layer, 9- thread eyes, 10- prisms, 11- optical fiber,

Embodiment:

As shown in figure 1, a kind of ultra-fine OCT image conduit, including plug receptacle 1, entering to note section 2, maincenter pipe 3 intervenes section 4;On conduit End is provided with maincenter pipe 3;The maincenter pipe 3 respectively with plug receptacle 1, enter to note section 2 with intervention section 4 be connected;The plug receptacle 1 and OCT Equipment is connected;It is described to enter to note section 2 and be connected with injection device;Intervention section 4 outermost layer is outer protection tube 7, the front end of the outer protection tube 7 It is provided with thread eye 9.

Plug receptacle 1 connects OCT equipment, for conduit provides light source and rotary power.Enter to note the connection injection device of section 2, be used for The injection of contrast agent.Intervention section 4 center is optical fiber 11, and the front end of optical fiber 11 is the prism 10 with fixed light reflection angle, light Fine 11 outer cladding bourdon tubes 5, the optical fiber 11 stretched out outside bourdon tube 5 is coated with microthin coating 8.Microthin coating 8 can play transmission and turn round The effect of square, it is ensured that spin stabilization before and after optical fiber;Microthin coating 8 increased the flexibility of optical fiber 11 so that conduit is by tortuous disease Prevent optical fiber from fractureing during stove.Intervention section 4 outermost layer is outer protection tube 7, and outer protection tube 7 is made up of the good material of translucency, improves into As quality.The front end of outer protection tube 7 is provided with thread eye 9, for penetrating seal wire.The outer protection tube that optical fiber 11 is stretched out at bourdon tube 5 is provided with Taper gradual change 6, reduces stress concentration, prevents deformation of guide tube;Ensure that the concentricity of optical fiber and conduit;Increased the suitable of conduit Slip, is more easy to by tortuous vascular site.The uncoated bourdon tube of optical fiber of catheter proximal end, but coating microthin coating, drop significantly Low conduit diameter size, can enable the duct to greatly be expanded by the capilary cavity of whole body the application model of OCT Enclose.
