Abstract
The invention relates to an OCT (optical coherence tomography) catheter for reducing usage of a contrast medium; the OCT catheter comprises a catheter, a connection segment, an injection segment, an intervention segment, and a center tube; the center tube is connected respectively to the connection segment, the injection segment and the intervention segment; an outer tube of the intervention segment is a multi-cavity tube; the multi-cavity tube includes a center cavity and a side cavity; the front end of the center cavity is closed, and an imaging tube is arranged in the center cavity; the side cavity is used for the passage of a guide wire; the injection segment is connected with an injector; the connection segment is connected to OCT equipment. The closed design for the front end of the center cavity can prevent blood from flowing into the center cavity, so that injecting a contrast medium to discharge the blood in the catheter is not required; therefore, the OCT catheter allows reduced overall usage for the contrast medium, the adverse effect of the contrast medium upon human bodies is reduced, surgical time is shortened, surgical difficulty is lowered, and surgical success rate is increased.
Description
【Technical field】
The present invention relates to a kind of imaging catheter device, more particularly to a kind of OCT image conduit for reducing contrast agent consumption.
【Background technology】
Optical coherence tomography (Optical Coherence Tomography, abbreviation OCT) applies modern computer graphical
Treatment, advanced optical technology is integrated with hypersensitive detector, has evolved into a kind of emerging fault imaging diagnosis skill
Art.Since obtaining high-definition image in human coronaries from the external application OCT technology of report first in 2001, OCT technology exists
Application report gradually increases in coronary heart disease intervention field.Compared with other imaging techniques, OCT has the resolution ratio of superelevation, not only
The form and composition of atherosclerotic plaques can clearly be observed, for the adherent situation of support that IVUS etc. cannot judge and
The postoperative endometrial hyperplasia situation of stenter to implant, OCT is distinguishable and evaluates, therefore OCT has nothing in the intervention diagnosis and treatment of coronary heart disease
Play an important roll in alternative effect, and Long-term after stenting.
Injection contrast agent is generally needed during the intervention diagnosis and therapy that coronary heart disease is carried out using OCT to be preferably imaged, so
And also highlighted therewith on contrast medium associated nephropathy problem, radiographic contrast nephropathy also oneself into there is acute kidney in Hospitals at Present
The common cause of exhaustion, also causes late period cardiovascular event incidence to increase, its acute renal failure disease caused by drug poisoning
Because in, it is only second to antibiotic and occupies the 2nd, though incidence is less than 2%, hair survivor's death rate is up to 34%.Therefore contrast agent is reduced
Consumption in OCT uses will reduce the illness rate of radiographic contrast nephropathy, there is very important positive role to patient health.
To sum up, work out it is a kind of reduce contrast agent consumption OCT conduits turn into currently need badly.
【The content of the invention】
The problem to be solved in the present invention is to provide a kind of OCT image conduit for reducing contrast agent consumption, in being performed the operation for intervention, leads to
The design of remaining silent of the chambers of the heart in the catheter is crossed, the consumption of contrast agent is reduced, operating time is shortened.
To achieve the above object, the technical scheme taken of the present invention is：
A kind of OCT image conduit for reducing contrast agent consumption, including conduit, linkage section, enter and note section, intervene section, maincenter pipe;It is described
Conduit is provided with maincenter pipe, the maincenter pipe respectively with linkage section, enter to note section, intervention section and be connected；The intervention section outer tube is many
Lumen；The multi-lumen tube is contained within center cavity and side chamber;To remain silent, the center cavity inside is imaging for the center cavity front end
Pipe；The side chamber is used to penetrate guide seal wire；It is described to enter to note section connection injection device；The linkage section is connected with OCT equipment.
Further, the multi-lumen tube is made up of the good material of translucency.
Compared with prior art, the present invention has the advantages that：
The catheter center chamber front end is design of remaining silent, and when in use, blood may not flow into center cavity, does not interfere with optic probe and sweeps
Retouch imaging, thus contrast agent discharge blood need not be injected, not only reduce contrast agent consumption, reduce contrast agent to human body not
Good influence, while decreasing operating time, reduces operating difficulty, improves success rate of operation.
【Brief description of the drawings】
Fig. 1 is a kind of OCT image conduit for reducing contrast agent consumption 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- linkage sections, 2- enters to note section, 3- maincenter pipes, 4- intervention sections, 5- side chambers, 6- center cavities, 7- multi-lumen tubes.
Embodiment:
As shown in figure 1,
A kind of OCT image conduit for reducing contrast agent consumption, including linkage section 1, enter to note section 2, intervene section 4, maincenter pipe 3;It is described
Conduit is provided with maincenter pipe 3, the maincenter pipe 3 respectively with linkage section 1, enter to note section 2, intervention section 4 and be connected；Outside the intervention section 4
It is multi-lumen tube 7 to manage；The multi-lumen tube 7 is contained within center cavity 6 and side chamber 5;The front end of the center cavity 6 is to remain silent, the center cavity 6
Inside is image forming tube；The side chamber 5 is used to penetrate guide seal wire；It is described to enter to note the connection injection device of section 2；The linkage section 1 with
OCT equipment is connected.
In operation, conduit penetrates blood vessel under the guide of seal wire and reaches lesions position, and the effect of side chamber 5 is exactly for wearing
Enter seal wire.To remain silent, inside is image forming tube to the front end of center cavity 6.The design of remaining silent of center cavity 6 can prevent blood from flowing into center cavity shadow
Probe imaging is rung, and then contrast agent need not be injected by the blood discharge in conduit, so conduit of the invention reduces contrast agent
Overall consumption, reduce harmful effect of the contrast agent to human body, while decreasing operating time, reduce operating difficulty,
Improve success rate of operation.
Wherein, the multi-lumen tube 7 is made up of the good material of translucency.
General principle of the invention and principal character and advantages of the present invention has been shown and described above.The technical staff of the industry
It should be appreciated that the present invention is not limited to the above embodiments, the present invention is simply illustrated described in above-described embodiment and specification
Principle, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these change and
Improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention is by appending claims and its equivalent
Thing is defined.
