Description
Technical field
This utility model relates to a kind of heart arter patent ductus stopper.
Background technology
Patent ductus arteriosus is the one in common congenital heart disease, and refer to a kind of birth defect passage between aorta and pulmonary artery, multidigit is between aortic isthmus and left pulmonary artery root.Patent ductus arteriosus is mainly formed in the growth and development process of fetus, owing to have impact on the growth of heart by certain factor, thus defines patent ductus arteriosus.For the patient of patent ductus arteriosus, blood can flow to pulmonary artery by aorta through patent ductus arteriosus usually, and the blood entering pulmonary circulation returns left atrium and left ventricle again.Thus cause left atrium and left ventricular hypertrophy, expansion, finally cause left heart failure.If catheter diameter is comparatively thick, right ventricle plumpness, dynamic property pulmonary hypertension etc. also may be caused.
Heart arter patent ductus is common congenital heart disease, and traditional therapeutic modality is surgical operation.Operating Therapeutic Method, patient surgically need open breast, and its maximum shortcoming is: need extracorporeal circulation in (1) art, operation may cause complication and cause death; (2) surgery operating wound is large, postoperatively leaves cicatrix; (3) surgery cost is expensive; (4) patent ductus arteriosus surgical operation is dangerous when being grown up and caliber is larger increases.
From the eighties in 20th century along with the development of intubation intervention Treatment and diagnosis technology and raising, China progressively introduces Wicresoft's interventional technique treatment congenital heart disease, is developed rapidly by the method for Minimally Interventional Therapy patent ductus arteriosus, now very ripe.Compare traditional surgery, Minimally Interventional Therapy is the treatment of a kind of modern high technology invasive.By femoral venous puncture, under the guiding of medical imaging device, by guide wire along femoral vein, postcava until enter right ventricle, through pulmonary artery, enter aorta through patent ductus arteriosus.Subsequently delivery conduit is placed in patent ductus arteriosus position along guide wire, finally heart arter patent ductus stopper is pushed in delivery conduit patent ductus arteriosus place and implement Occlusion therapy.Such Minimally Interventional Therapy have do not operate on, wound is little, few intercurrent disease, recovery are fast, effective, indication scope is wide and surgery cost is relatively low etc. advantage.
Authorization Notice No. CN2737328Y utility model patent discloses a kind of ductus arteriosus stopper, and one end of this stopper is double-deck containing guard, and this guard is provided with connector, and the other end of stopper is Open architecture, for monolayer turns up guard.The monolayer of this stopper guard that turns up is open architecture, there is recovery and all poor problem of support force.
Utility model content
The technical problems to be solved in the utility model is that the wire side of non-installation connecting element in order to overcome existing stopper exists recovery and all poor defect of support force, provides a kind of heart arter patent ductus stopper.
This utility model solves above-mentioned technical problem by following technical proposals:
A kind of heart arter patent ductus stopper, it comprises the one first plate-like net, a tubular reticulum and the one second plate-like net that connect successively, its feature is, described first plate-like net is double-deck guard, described second plate-like net is monolayer guard, the two ends of described tubular reticulum are connected to the interior wire side of described first plate-like net and described second plate-like net, and described first plate-like net, described tubular reticulum and described second plate-like net are formed in one; The outer net face of described first plate-like net comprises a closing in end, the described end that closes up is for multiple ring-type netting twine adjacent successively, described first plate-like net is also provided with a closing in line, described closing in line is arranged in all described ring-type netting twines, after described closing in line closes up, the outer wire side of described first plate-like net forms netted of continuous print, and described second plate-like net is welded with a connector closed up by wire side.
Preferably, the described end that closes up is positioned at the center of the outer wire side of described first plate-like net.Like this, make outer wire side more smooth.The risk that stopper surface local thrombus is formed can be reduced, be conducive to accelerating the endothelialization process on stopper surface, make patent ductus arteriosus place being repaired by autologous tissue more early.Meanwhile, decrease the release length of stopper in operation process, significantly can reduce the damage to heart, make operation more effective, safer.
Preferably, the external diameter of described first plate-like net is greater than the external diameter of described second plate-like net.First plate-like net is positioned at aorta side; second plate-like net is positioned at pulmonary artery side; for the patient of patent ductus arteriosus; blood can flow to pulmonary artery by aorta through patent ductus arteriosus usually; so this structure makes the first plate-like netting gear being positioned at aorta side have larger support force; the impact of blood flow can be resisted, to make stopper more firmly be clamped in patent ductus arteriosus place, realize effective shutoff.
Preferably, the external diameter of described first plate-like net 5.5-6.5mm larger than the external diameter of described second plate-like net.First plate-like net is positioned at aorta side; second plate-like net is positioned at pulmonary artery side; for the patient of patent ductus arteriosus; blood can flow to pulmonary artery by aorta through patent ductus arteriosus usually; so this structure makes the first plate-like netting gear being positioned at aorta side have larger support force; the impact of blood flow can be resisted, to make stopper more firmly be clamped in patent ductus arteriosus place, realize effective shutoff.
Preferably, the length of described tubular reticulum is 4.5-6.5mm.This length can adapt with the length at patent ductus arteriosus place, makes stopper can firmly be clamped in patent ductus arteriosus place, effective Transcatheter Closure of Patent Ductus Arteriosus, also can not affect the flowing of pulmonary artery inner blood.
Preferably, the material of described first plate-like net, described tubular reticulum and described second plate-like net is nitinol alloy wire.
Positive progressive effect of the present utility model is: the structure adopting closing in line to close up at wire side center due to this stopper, therefore, when manufacturing stopper, the NiTi silk screen that can intercept tubular is suppressed, and then shell nosing treatment is carried out to the outer wire side of the first plate-like net, form smooth netted, add support force and the recovery of stopper; In addition, this stopper also has the advantage of low cost of manufacture.
