Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, is specifically related to a kind of heart septal defect blocking device for the treatment of congenital heart disease.
Background technology
Congenital heart disease comprises patent ductus arteriosus (PDA), patent foramen ovale (PFO), atrial septal defect (ASD) and indoor every damaged (VSD) etc.PDA may make blood flow between aorta and pulmonary artery, and PFO and ASD may make blood flow between left atrium and right atrium, and VSD may make blood flow between left ventricle and right ventricle, and flow more generally needs to repair.At present existing polytype heart septal defect plugging device is used for the treatment of geneogenous heart disease, and these plugging devices are delivered to the patient's heart certain location by conduit or lead through femoral vein or jugular vein.
Past has proposed some and has been used for the mechanicalness locking device of the congenital heart defect of shutoff.Wherein widely used, representative example is disclosed in people's such as Frank Ke Shila CN97194488.1 and the patent of CN 98808876.2, and wait in people's the patent of CN98813470.5 now the Ku Ertean pula.This device generally comprises a supporting network with the default profile of shrinkage, the built-in choked flow film of supporting network.Supporting network discharges after being elongated and delivering to the intravital defect of patient in conduit, reaches the effect of shutoff.This device has easy recovery, from the good characteristics of centrality.But it is outside that metallic support net left and right sides disk seal head process goes out at metallic support net about 1 dishes, shown in Figure 1A, 1B, 1C, 1D; Make stopper left side disk seal head 4 to enter large artery trunks (being used for PDA), left atrium (being used for PFO, ASD) and left ventricle (being used for VSD) with outstanding state, perienchyma's (as aortic valve and other internal cardiac structures of left pulmonary vein mouth, orifice of coronary sinus and the left ventricle of left atrium) may be touched or damage to end socket, causes serious injury; Because end socket 4, end socket 5 is in metallic support net 1 outside, for reducing the injury of end socket to heart perienchyma, in the groove that part end socket indentation one is preset that has, even it is fluted, under free expansion state, end socket is in groove, but when stopper left side dish just when sheath pipe 8 discharges, end socket still can be given prominence to outside, as Fig. 1 E, also groove only can about dish at interval bigger PDA stopper make, for left side dish 2, the right dish 3 intervals only VSD stopper of about 2mm then can't be made, therefore it does not solve the outstanding harm outside of end socket at all, and the groove of card might influence the mode of blood flow.Under existing technical conditions and operational means, be difficult to accurately determine damaged hole size and shape simultaneously, because the restriction of waist sizes, increased the difficulty of doctor aspect selection plugging device model, if numerical selection is bigger than normal, dish was heaved and is formed the calabash shape about the stopper waist was made by the cardiac septum compression, make at the end socket of metallic support net outside more outstandingly, the danger that touches perienchyma is arranged, cause serious consequence.The choked flow film is arranged again in metallic support net inside, about check and regulate a metallic support net and be exposed to fully in the blood, cause the formation of thrombosis and the release of harmful metallic element easily, influence surgical effect.
The utility model content
Give prominence in metallic support net outside in order to overcome the existing end socket that is used for the locking device of shutoff congenital heart disease, the deficiency that perienchyma is existed harm, the purpose of this utility model is: a kind of heart septal defect blocking device is provided, this stopper has been removed the harm of end socket touching perienchyma, can reduce the incidence rate of thrombosis.
The technical scheme that its technical problem that solves this utility model adopts is as follows:
A kind of heart septal defect blocking device, its main body are the metallic support nets with default expansion profile.Its front end is provided with a left side dish, and the rear end is provided with a right dish, an end socket is respectively arranged with the sealing of metallic support net in the nearly center of left and right card, and fixedlys connected with the metallic support net.The end socket at left end or left and right two ends is by the inside of metallic support net of anti-package in sealing, and fixedlys connected with the metallic support net.The outer card central part of anti-package end socket does not promptly have end socket is not had obvious groove, the almost plane shape yet.
Can be surrounded by one deck choked flow film at the outer surface of described left side dish or left and right two dishes, this choked flow film is fixedlyed connected with left side dish or left and right two dish outer surfaces.
Can between described end socket, connect a backguy of respective length.
The beneficial effects of the utility model are:
Because left disk seal head anti-package is in stopper inside, make outer left card form a more smooth card that does not have end socket, not only removed the harm of end socket touching heart inner rim tissue, but also reduced the mode that influences blood flow, reduced the thrombosis rate, and created condition for outsourcing choked flow film; Because the choked flow film encased left card, help promoting the growth of endothelium, reduced the formation rate of thrombosis and the release of harmful metallic element.Because end socket wraps in metallic support net inside, even stopper forms the calabash shape, can not touch perienchyma yet, it is more reliable that the doctor is operated.
