Description
Technical field
This utility model relates to medical science guiding puncture technique field, is specifically related to a kind of positioning catheter and adopts the puncture arrangement for guiding of this positioning catheter.
Background technology
Atrial septal puncture art is by Ross etc. in nineteen fifty-nine reported first, and after this Brockenbrough and Mullins etc. are improved puncture needle and sheath pipe and puncture technique on this basis.Be mainly used in the left heart catheterization of valve pathological changes at that time, constantly popularizing now along with catheter ablation for atrial fibrillation, melting atrial septal puncture art has become clinical common technology.
Atrial septal puncture can be used for that left shunt melts through interatrial septum approach, atrial fibrillation is melted in catheter ablation operation, left atrium atrial tachycardia ablation and left room atrial flutter ablation, meanwhile, atrial septal puncture is also the alternative route that melts of the relevant arrhythmia of left ventricle and necessary complement.
The conduit of cutaneous routes direct motion can not arrive left atrium, and need by aortic valve and Bicuspid valve, this two place all has certain camber, and conduit is difficult to reach, and can reach in time, and catheter manipulation is also very loaded down with trivial details.
Interatrial septum is between left atrium, and fossa ovalis is position the thinnest on interatrial septum, and therefore fossa ovalis is the ideal position that atrial septal puncture enters left atrium.When atrial septal puncture, first need the position determining fossa ovalis.In traditional operation, puncture mainly through radiation Anatomical orientation method.By showing shape and the position of lancing system under X-ray two-dimentional system, moved on interatrial septum by the head end of arrangement for guiding, the anatomical structure due to fossa ovalis is a recessed nest shape, in moving process, certain dynamics can be had to feed back to operator, thus determine the position of fossa ovalis.After determining the position of fossa ovalis, also need X-ray irradiation development under certain angle, judge that whether lancing system is perpendicular to face, interatrial septum.If vertical, just can insert puncture needle and carry out atrial septal puncture, danger may be caused in the puncture direction of mistake.
In traditional atrial septal puncture art, location and the puncture direction of fossa ovalis are determined to need doctor to have good experience, even so, still need repeatedly to use X-ray to show heart shape and judge the position of arrangement for guiding and determine direction of puncturing.This causes a large amount of radiation to patient and doctor.
Sichuan Jinjiang Electronic Science and Technology Co., Ltd. proposes a kind of technology, this technology can construct the three-dimensional stereo model of the interatrial septum wall surface of fossa ovalis, and can show on the display of computer intuitively, the position that can be locating fossa ovalis provides more convenient more reliable information, can reduce due to individual variation cause the impact of the location on fossa ovalis position, but, prior art is difficult to the particular location of accurate location guiding piercing assembly at heart, and be difficult to judge that whether arrangement for guiding front end vertical with face, interatrial septum accurately, these are all very easy to cause site of puncture mistake, great pain and sufferer risk is brought to patient.
In sum, be difficult at present to position the arrangement for guiding that medical science puncture field uses accurately in real time, easily cause site of puncture mistake, bring huge misery and sufferer risk to patient.
Therefore, need a kind of technology badly, can accurately to the arrangement for guiding for atrial septal puncture that the arrangement for guiding used during puncture positions.
