A kind of arrhythmia radio-frequency (RF) ablation blood vessel camera end sacculusTechnical field
Arrhythmia radio-frequency (RF) ablation blood vessel camera end sacculus of the present invention belongs to medical instruments field and in particular to a kind of arrhythmiaRadio-frequency (RF) ablation blood vessel camera end sacculus.
Background technology
Arrhythmia is common cardiovascular disease, more and more obvious with China human mortality aging, and some complicated arrhythmia are sent outRaw rate accordingly raises；2014, China's Epidemiological study showed, atrial fibrillation rises to respectively in >=60 years old men and women's prevalence1.83% and 1.92%；As atrial fibrillation, ventricular arrhythmia prevalence raises also with aged tendency of population level and raises.
From 20 century 70s, with DSA, cardiac three-dimensional imaging sequential use in clinic, and radio frequencyWith the progress of the development of medical apparatus and instruments and arrhythmia rationale, Percutaneous radiofrequency ablation ablation has become ARR one of radical cureMain Means, are greatly improved ARR diagnosis and treatment level.But compare supraventricular tachycardia radiofrequency ablation therapyFor art, atrial fibrillation and ventricular arrhythmia radio-frequency (RF) ablation either in anatomical structure, or on electrophysiological mechanism all morePlus complicated, and, Percutaneous radiofrequency ablation ablation is all the imaging skill being imaged this non-intuitive using DSA and cardiac three-dimensionalArt, doctor or patient it is seen that the cardiovascular organization image that processed through computer, do not reach similar Gastrointestinal Endoscopes, peritoneoscope thatSample intuitively observing effect, this also becomes the very important factor that current restriction arrhythmia radio-frequency ablation procedure continues to advance.
Angioscope method is a kind of method that application angioscope obtains visual image, compares DSA, cardiac three-dimensional imaging skillArt is more directly perceived, more accurate, and angioscope develops the history having for more than 90 years so far, but before the eighties, due to cardiovascularThe interior image that cannot obtain full of blood, angioscope, contributes to the inspection during cardiac thoracic surgery.Entering 20 generationAngioscope after the eighties of recording starts to assemble the air bag of effective blocking blood flow, the comparable change being clear that lumen of vessels, and this isReally promote angioscope and be used for clinic, also start the epoch that angioscope intervention checks.But need frequency during due to AngioscopyNumerous blocking blood flow, open blood flow, constrain the clinical practice of angioscope.Although patent (the united states occurring in recent yearsPatent number4784133) blood vessel camera end is had made some improvements, define certain work platformses in head end, but exist brightAobvious defect, one is cannot to solve blood between blood vessel camera lens and cardiovascular organization to be emptied completely problem；Two is blood vessel camera endHarder, and operate relative complex；Three is the interventional therapy that cannot complete with angioscope for work platformses for cardiovascular disease.
Content of the invention
It is an object of the invention in place of avoiding the deficiencies in the prior art, and provide one kind can be connected with blood vessel camera end, can be full ofLiquid, transparent, shape can be with the cardiovascular organization alteration of form being in contact with it, and disposable arrhythmia radio-frequency (RF) ablation is usedBlood vessel camera end sacculus.
The present invention is to reach above-mentioned purpose, including sacculus, balloon tip electrode, expandable prosthetic electrode, balloon electrode wire, ballCapsule blood vessel camera end interface.Sacculus is double-decker, is divided into internal layer and outer layer；Balloon tip electrode and expandable prosthetic electrode and ballIntracapsular layer and outer layer linking, and be exposed at outside sacculus；Balloon electrode wire is connected with balloon tip electrode and expandable prosthetic electrode,Traveling is between sacculus internal layer and outer layer；Balloon camera lens end interface is engaged on balloon interior, balloon camera lens end interface twoEnd hollow, the inside is helical structure, and balloon camera end interface internal tail end has balloon electrode conductor interface, with balloon electrodeWire connects.For reducing the damage to sacculus for the balloon camera lens end interface, adopt streamlined outside balloon camera lens end interfaceDesign.
The beneficial effect that the present invention obtains is (1) is offer one when the inspection of angioscope row cardiovascular and arrhythmia radiofrequency ablation therapyPlant medium and platform, eliminate the impact to image for the blood, without blocking blood flow, easy and simple to handle；(2) can look at straight in angioscopeDescending arrhythmia radiofrequency ablation therapy, reduces the use of ray, and simple, convenient, safety, reduces patient and medical personnel penetrateThe irradiation of line.

Specific embodiment
In order that present disclosure is easier to be clearly understood, below according to specific embodiment and combine accompanying drawing, to the present inventionIt is described further.
As shown in Fig. 1,2,3,4,5, a kind of arrhythmia radio-frequency (RF) ablation blood vessel camera end sacculus, including sacculus 1, ballCapsule blood vessel camera end interface 2, balloon tip electrode 3, expandable prosthetic electrode 4, balloon electrode wire 5, sacculus 1 is double-deck knotStructure, is divided into internal layer and outer layer；Balloon tip electrode 3 and expandable prosthetic electrode 4 are connected with sacculus 1 internal layer and outer layer, and are exposed atOutside sacculus 1；Balloon electrode wire 5 traveling between sacculus 1 internal layer and outer layer, with balloon tip electrode 3 and expandable prostheticElectrode 4 connects；Balloon camera lens end interface 2 is engaged on inside sacculus 1, balloon camera lens end interface 2 two ends hollow,The inside is helical structure 2-1, and balloon camera lens end interface 2 inner tail end has balloon electrode conductor interface 2-2, with balloon electrodeWire 5 connects.For reducing the damage to sacculus 1 for the balloon camera lens end interface 3, adopt outside balloon camera lens end interface 3Use airflow design.
