Abstract
Provided is an elliptical eccentric interventricular septal defect stopper, relating to the technical field of congenital heart disease interventricular septal defect treatment. The stopper comprises an elliptical titanium-nickel wire support (1), a stainless steel sleeve (2), polyester films (3), and a suture (4). The stainless steel sleeve (2) is arranged on the elliptical titanium-nickel wire support (1), 3-5 polyester films (3) are arranged in the elliptical titanium-nickel wire support (1), and the 3-5 polyester films (3) are fixed on the elliptical titanium-nickel wire support (1) through the stitching of the suture (4). The stopper provided is simple in structure and achieves the aim of interventricular septal defect healing, as well as prevents the life safety problem caused by the disc surface which touches the aortic valve due to the overlarge edge.
Description
Technical field:
This utility model relates to Closure of Ventricular Septal Defects treatment technology field, relates in particular to a kind of oval eccentric type ventricular septal defect.
Background technology:
Closure of Ventricular Septal Defects, atrial septal defect is a kind of common Congenital Heart disease, the characteristics of pathological changes are on a left side, right atrium and a left side, normally closed is failed at interval between right ventricle after birth, due to the pressure of left atrium and left ventricle higher than right atrium and right ventricle, under pressure, the blood part in left side branches to right atrium or right ventricle through atrial septal defect or ventricular septal defect, the burden that causes the right side to feel concerned about system increases, cause right ventricular hypertrophy, pulmonary circulatory blood volume increases, finally can cause pulmonary hypertension, arrhythmia and heart failure, in the past to ventricular septal defect, traditional Therapeutic Method of atrial septal defect is surgical operation, surgical operation needs general anesthesia, open breast, extracorporeal circulation, need blood transfusion in art, large to patient trauma, the incidence rate of complication is high, and stay the operative incision cicatrix at body surface.
through the vessel occlusion ventricular septal defect, the main apparatus of atrial septal defect is a kind of for the closed-chamber septal defect, the utensil of atrial septal defect, be called stopper, stopper is dual disc, the stopper disc is formed by the braiding of superelastic metal silk, send into the position of heart defect through the heart conduit, release the rear original shape that automatically recovers design in conduit, be clipped in damaged interatrial septum or the both sides of ventricular septal defect, make damaged closure, reach the healing ventricular septal defect, the purpose of atrial septal defect, existing stopper in use can cause the life security problem due to the excessive touching aortic valve in the limit of card.
The utility model content:
The purpose of this utility model is to provide a kind of oval eccentric type ventricular septal defect, and it is simple in structure, can reach the purpose of curing thermal defect septal defect, prevents the life security problem that causes due to the excessive touching aortic valve in the limit of card.
In order to solve the existing problem of background technology, this utility model is by the following technical solutions: it is comprised of oval titanium-nickel wire support 1, stainless steel sleeve 2, polyester film 3, stitching thread 4; Be provided with stainless steel sleeve 2 on oval titanium-nickel wire support 1, be provided with 3-5 sheet polyester film 3 in oval titanium-nickel wire support 1, polyester film 3 is sewed up by stitching thread 4 and is fixed on oval titanium-nickel wire support 1.
Described oval titanium-nickel wire support 1 forms for the braiding of super-elasticity Nickel-titanium alloy for medical purpose silk.
Described stainless steel sleeve 2 is that the stainless steel sleeve end of its afterbody is provided with a nut for the fixing nitinol alloy wire at two ends, is complementary with the screw of induction system push rod head end.
Described polyester film 3 is to be formed by pure polyester fiber non-woven fabric cutting, and each support intracavity has the polyester film of 3-5 layer.
Described stitching thread 4 is medical continuous synthetic fibre line, is used for polyester film 3 is sewed up being fixed in oval titanium-nickel wire support 1.
This utility model is simple in structure, can reach the purpose of curing thermal defect septal defect, prevents the life security problem that causes due to the excessive touching aortic valve in the limit of card.

Fig. 2 is perspective view of the present utility model.
The specific embodiment:
With reference to Fig. 1, Fig. 2, this specific embodiment by the following technical solutions: it is comprised of oval titanium-nickel wire support 1, stainless steel sleeve 2, polyester film 3, stitching thread 4; Be provided with stainless steel sleeve 2 on oval titanium-nickel wire support 1, be provided with 3-5 sheet polyester film 3 in oval titanium-nickel wire support 1, polyester film 3 is sewed up by stitching thread 4 and is fixed on oval titanium-nickel wire support 1.
Described oval titanium-nickel wire support 1 forms for the braiding of super-elasticity Nickel-titanium alloy for medical purpose silk.
Described stainless steel sleeve 2 is that the stainless steel sleeve end of its afterbody is provided with a nut for the fixing nitinol alloy wire at two ends, is complementary with the screw of induction system push rod head end.
Described polyester film 3 is to be formed by pure polyester fiber non-woven fabric cutting, and each support intracavity has the polyester film of 3-5 layer.
Described stitching thread 4 is medical continuous synthetic fibre line, is used for polyester film 3 is sewed up being fixed in oval titanium-nickel wire support 1.
This specific embodiment is simple in structure, can reach the purpose of curing thermal defect septal defect, prevents the life security problem that causes due to the excessive touching aortic valve in the limit of card.
