Abstract
The utility model discloses a nano-film single-rivet occluder for congenital heart disease interventional therapy. The occluder comprises a support, a metal sleeve and a flow blocking layer. The support comprises a head disc, a tail disc and a waist portion arranged between the head disc and the tail disc and is woven through nickel-titanium alloy wires and provided with a net structure. A nano film layer is coated on the nickel-titanium alloy wires, and the metal sleeve is arranged at the center of the tail disc. The head disc is in a flat net structure. According to the occuluder, the metal sleeve is only arranged at the center of the tail disc instead of the center of the head disc, the head disc has a flat end surface and cannot cause unnecessary injuries to human bodies easily, and the effect on blood flowing can be reduced to the greatest extent.
Description
Technical field
This utility model relates to a kind of nanometer film list riveting stopper, for interventional therapy in congenital heart diseases, belongs to medical instruments field.
Background technology
Heart septal defect is a kind of common congenital heart disease, and the mechanism of pathological changes is that normally closed is failed at the interval between left and right ventricles or left atrium.Healthy people, the blood pressure of its left heart is higher than the blood pressure of the right heart.Patients with congenital heart is failed normally closed due to the interval between left and right ventricles or left atrium, causes the burden of its heart to increase, and its pulmonary circulatory blood volume increases, and finally can cause pulmonary hypertension, arrhythmia and heart failure.Generally adopt at present heart occluder, shutoff heart defect position.
Refer to Fig. 1, conventional heart occluder is dual disc, comprise support 1 ', head stainless steel sleeve 21 ' and afterbody stainless steel sleeve 22 ', support 1 ' comprise head disk 11 ', afterbody disk 12 ' and described head disk 11 ' and described afterbody disk 12 ' between waist 13 '; Head stainless steel sleeve 21 ' be arranged on head disk 11 ' center; Afterbody stainless steel sleeve 22 ' be arranged on afterbody disk 12 ' center.Support 1 ' formed by nitinol alloy wire braiding, for braided support 1 ' nitinol alloy wire, support 1 ' head disk 11 ', afterbody disk 12 ' center fixedly become nitinol alloy wire bundle, head stainless steel sleeve 21 ' and afterbody stainless steel sleeve 22 ' correspondingly described Nitinol tow is fixed.
Refer to again Fig. 2 and Fig. 3, because stopper adopts head stainless steel sleeve 21 ' and afterbody stainless steel sleeve 22 ' fixing made more, the head disk 21 of heart occluder ' and afterbody disk 22 ' card certainly will be uneven, for hemodynamics, association affects; Heart occluder need to be by recovering needed shape after tiny tube chamber, due to head stainless steel sleeve 21 ' and afterbody stainless steel sleeve 22 ' existence, the heart occluder heart inner tissue of easily stabbing in sending conduit, causes unnecessary injury; And due to head stainless steel sleeve 21 ' and afterbody stainless steel sleeve 22 ' existence, endothelialization and hematodinamics are organized in impact; Use in addition the support 1 that head stainless steel sleeve 21 ' and afterbody stainless steel sleeve 22 ' fixing nitinol alloy wire is woven into ', owing to existing chemical potential poor between dissimilar metal, in solution, easily cause galvano-cautery, therefore the corrosion resistance of stopper is poor.
Utility model content
The purpose of this utility model is that a kind of nanometer film list riveting stopper is provided in order to overcome the deficiencies in the prior art, it can make head disk have more smooth end face, be difficult for human body to cause how unnecessary injury, and can reduce the impact on blood flow as far as possible.
A kind of technical scheme that realizes above-mentioned purpose is: a kind of nanometer film list riveting stopper, comprise support, metallic sheath and impermeable barrier, described support comprises head disk, afterbody disk, and waist between described head disk and described afterbody disk, wherein, described support is woven into by nitinol alloy wire, there is network structure, described impermeable barrier is built in described support, is coated with nanometer rete on described nitinol alloy wire, and described metallic sheath is located at the center of described afterbody disk.
Above-mentioned a kind of nanometer film list riveting stopper, wherein, described nanometer rete is TiOx nano rete or titanium nitride nano rete.
Above-mentioned a kind of nanometer film list riveting stopper, wherein, described head disk is smooth network structure.
Above-mentioned a kind of nanometer film list riveting stopper, wherein, described metallic sheath is made up of medical stainless steel.
Above-mentioned a kind of nanometer film list riveting stopper, wherein, the head disk of described support, afterbody disk and waist have double-deck network structure or multilamellar network structure.
Above-mentioned a kind of nanometer film list riveting stopper, wherein, described head disk and afterbody disk are umbrella or mushroom.
Above-mentioned a kind of nanometer film list riveting stopper, wherein, described impermeable barrier is made up of medical macromolecular materials.
Above-mentioned a kind of nanometer film list riveting stopper, wherein, described medical macromolecular materials are polyethylene terephthalate or politef.
Adopt the technical scheme of a kind of nanometer film list riveting stopper of the present utility model, by being located at the fixing netted support being woven into by nitinol alloy wire of metallic sheath on afterbody disk, the technical scheme that suppresses the release of nickel ion by be coated with nanometer rete on nitinol alloy wire.Its technique effect is: make head disk have more smooth end face, be difficult for human body to cause how unnecessary injury, can reduce organizing endothelialization and hemodynamic impact as far as possible, and on nitinol alloy wire, be coated with one deck nanometer rete, can suppress the release of nickel ion, reduce owing to existing chemical potential poor and easily cause galvano-cautery in solution between dissimilar metal, improve the corrosion resistance of stopper.
