Abstract
The utility model discloses a membrane ventricular septal defect plugging device which comprises a metal net, wherein the outline of the metal net is preset. The metal net is divided into a left disc face, a right disc face and a waist part, wherein the left disc face and the right disc face are connected through the waist part. A sealing head is arranged on the left disc face. A bolt head is arranged on the right disc face. The sealing head and the bolt head are fixedly connected with the metal net and the metal net is sealed by the sealing head and the bolt head. A flow chocking membrane is arranged in the metal net. The height of the waist part is 3.0-10.0 mm. According to the membrane ventricular septal defect plugging device, the diameter of the waist part is matched with the size of ventricular septal defect, the height of the waist part is matched with the thickness of ventricular septum, the edge of the plugging device is enabled to be perfectly attached to the ventricular septum, pressing blocking and friction of partial endocardium are avoided, and severe arrhythmia such as III degree atrioventricular block is avoided.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, relate to specifically a kind of stopper of minimally-invasive treatment Congenital Heart perimembranous ventricular septal defect.
Background technology
Interventricular septum is the muscular septum of cutting apart left ventricle and right ventricle, is extended to the apex of the heart by infundibulum, and thickness increases gradually; And at different age brackets, the interventricular septal thickness at same position is also different, and with advancing age, thickness increases.Ventricular septal defect (VSD) is modal congenital heart disease, and this damaged blood that may make flows between left and right ventricles, need to repair damaged when blood flow is more.The stopper of generally using both at home and abroad has two kinds of symmetric form and eccentric types, but these two kinds of stopper design waist height are 1.5-2.0mm, can not be complementary with the interventricular septal thickness at all positions, patient VSD place, generally speaking, child's interventricular septal thickness is 3.0mm-5.0mm, and adult's interventricular septal thickness is 7.0-10.0mm.
Yet the waist height is placed to the VSD that interventricular septal thickness surpasses 2mm for the stopper of 1.5mm-2.0mm, certainly will cause the stopper edge that the endocardial card of local interventricular septum is pressed, along with heartbeat also causes repeatedly friction, the most seriously can affect subendocardial conductive beam, cause severe arrhythmia, such as III ° of atrioventricular block.
Summary of the invention
The present invention will provide a kind of stopper that is applicable to perimembranous ventricular septal defect, and stopper disclosed in this invention is applicable to different chamber's spacer thickness.
The present invention adopts following technical scheme:
A kind of perimembranous ventricular septal defect stopper, comprise the wire netting with default profile, wire netting is divided into left card, right card and the waist that is connected left and right sides card, an end socket is arranged on the left card, a bolt head is arranged on the right card, and end socket is fixedly connected with wire netting with the bolt head, and wire netting is sealed, metal mesh built-in choked flow film is characterized in that: the waist of waist is high to be 3.0mm-10.0mm.
Further, described stopper left and right sides card shape same position is symmetrical.
Further, described stopper left and right sides card is eccentric type.
Further, the diameter at the minimum place of described stopper waist is 4.0mm-16.0mm.
Further, described stopper wire netting adopts complete or collected works' titanium nonmagnetic alloy silk thread.
Further, the diameter of described stopper metal twine is 0.004 inch.
Further, a kind of perimembranous ventricular septal defect stopper group, this stopper group comprises the stopper of 8 waist height between 3.0mm-10.0mm, and the waist height of each stopper is respectively 3.0mm, 4.0mm, 5.0mm, 6.0mm, 7.0mm, 8.0mm, 9.0mm, 10.0mm in this stopper group.
The invention has the beneficial effects as follows:
Because the waist height of waist is 3.0mm-10.0mm between the card of the left and right sides, the diameter at the minimum place of waist is 4.0mm-16.0mm, the diameter of waist and ventricular septal defect size are complementary, height is complementary with interventricular septal thickness, the good plumage in stopper edge is labelled on the interventricular septum, in order to avoid cause local endocardial pressure card and friction, avoid the generation of the III ° of severe arrhythmia such as atrioventricular block.
The metal twine selects complete or collected works' titanium nonmagnetic alloy silk thread of 0.004 inch of diameter to be woven into net, and it is interior as the choked flow film that dacron patch is sutured in stopper, is convenient to rapid blocking blood flow.
