Description
Technical field
The present invention relates to medical science guiding puncture technique field, and in particular to a kind of sheath for atrial septal puncture.
Background technology
By Ross etc. in nineteen fifty-nine reported first, hereafter Brockenbrough and Mullins etc. is improved on this basis atrial septal puncture art to puncture needle and sheath and puncture technique.The left heart catheterization of valve pathology was mainly used at that time, and now with the continuous popularization of catheter ablation for atrial fibrillation, ablation atrial septal puncture art has become clinical common technology.
Atrial septal puncture can be used for the approach ablation of left shunt Jing atrial septums, auricular fibrillation ablation, atrium sinistrum atrial tachycardia ablation and left room atrial flutter ablation in catheter ablation operation, meanwhile, atrial septal puncture is also the alternative route and necessary complement of the relevant arrhythmia cordis ablation of left ventricle.
The conduit of cutaneous routes can not direct motion reach atrium sinistrum, need by aorta petal and bicuspid valve, this is respectively provided with certain camber at two, and conduit is difficult to reach, that is, allow to reach, and catheter manipulation is also very loaded down with trivial details.
Atrial septum is located between left atrium, and fossa ovalis is position most thin on atrial septum, therefore fossa ovalis is the ideal position that atrial septal puncture enters atrium sinistrum.In atrial septal puncture, it is necessary first to determine the position of fossa ovalis.It is main to be punctured by radiating Anatomical orientation method in traditional operation.By shape and position that lancing system is shown under X-ray two-dimentional system, the head end of arrangement for guiding is moved on atrial septum, because the anatomical structure of fossa ovalis is a recessed nest shape, in moving process, there can be certain dynamics to feed back to operator, so that it is determined that the position of fossa ovalis.Behind the position for determining fossa ovalis, in addition it is also necessary to the X-ray irradiation development under certain angle, judge lancing system whether perpendicular to atrial septum face.If vertical, just can be inserted into puncture needle carries out atrial septal puncture, and the puncture direction of mistake is likely to result in danger.
In traditional atrial septal puncture art, the positioning of fossa ovalis and the determination of puncture direction need doctor to have good experience, even so, still need to that X-ray is used for multiple times to show heart shape and judge that the position of arrangement for guiding and determination puncture direction.This causes substantial amounts of radiation to patient and doctor.
Sichuan Jinjiang Electronic Science and Technology Co., Ltd. proposes a kind of technology, the technology can construct the three-dimensional stereo model of the atrial septum wall surface of fossa ovalis, and intuitively can show on the display of computer, more convenient more reliable information can be provided for the position of locating fossa ovalis, can reduce due to caused by individual difference to the impact of the positioning of fossa ovalis position, but, prior art is difficult to accurately position particular location of the sheath in heart, and be difficult to accurately judge whether sheath front end vertical with atrial septum face, these are all very easy to cause site of puncture mistake, great pain and sufferer risk are brought to patient.
In sum, the sheath that current medical science puncture field uses is difficult to position, and easily causes site of puncture mistake, and to patient huge pain and sufferer risk is brought.
Therefore, need a kind of technology badly, accurately the sheath in heart can be positioned.
The content of the invention
