Abstract
The utility model relates to a stopper for ventricular septal defect, which comprises a left disk frame, a right disk frame, a pole body, a flow resisting body and a connection head, wherein the left disk frame, the right disk frame and the pole body which is used for connecting the left disk frame and the right disk frame are all in a telescopic metal net pipe structure. The left disk frame which is arranged at the side of a left ventricle is gradually recessed from two edges to the middle to form a leaf shape, so the left disk frame avoids important contiguous tissues, such as an aortic valve, etc. The left disk frame and the right disk frame are not parallel, and the left disk frame is gradually inclined to the right disk frame from bottom to top. The upper part of the distance of the disk edges of the left disk frame and the right disk frame is narrower than the lower part of the distance, the narrow position is arranged at a thinner film part, and the wide position is arranged at a thicker muscle part, and therefore, a stop effect is enhanced. The upper part of the left disk frame is inclined to make the left disk frame be away from the aortic valve to avoid damaging the aortic valve, etc. The utility model adopts medical terylene sheet as the flow resisting body to ensure the excellent biocompatibility of the utility model.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, is specifically related to a kind of shutoff device of medical human ventricular septal heart defect.
Background technology
The traditional therapy of human heart ventricular septal defect is to carry out surgical operation, the interventional therapy of congenital heart disease has obtained developing rapidly in recent years, the clinical practice of patent ductus arteriosus closing stopper, atrial septal defect closing stopper occurred.It is damaged on every side damaged on every side with pars muscularis that interventricular septal defect is divided into membranous part, and membranous part peripheral chambers septal defect is modal congenital heart disease.Existing ventricular septal defect blocking apparatus only is applicable to the muscular ventricular septal defect that accounts for ventricular septal defect 1-5%.And the structures surrounding complexity of membranous ventricular septal defect, contiguous aortic valve, Bicuspid valve, Tricuspid valve are its conductive beam, right ventricle in more than the muscle bundle etc.At present, the ventricular septal defect blocking apparatus of development can cause and close on above-mentioned tissue, particularly can cause aortic valve damage and produce severe complication such as aortic regurgitation, thereby the interventional therapy of membranous ventricular septal defect does not still have sophisticated closing stopper and can be applicable to clinical.
The utility model content
In order to overcome existing ventricular septal defect blocking apparatus easy damaged important adjacent tissue structure on every side, be difficult to be applied to clinical deficiency, this utility model provides a kind of ventricular septal defect blocking apparatus, this ventricular septal defect blocking apparatus can block up and close polytype ventricular septal defect, have the good stifled effect of closing, the most important thing is this closing stopper can avoid damaging damaged around important adjacent tissue structure such as aortic valve; And its easy-to-operate.
The technical scheme that its technical problem that solves this utility model adopts is:
A kind of ventricular septal defect blocking apparatus, comprise left and right double-deck plate rail, connect by cylinder between the left and right plate rail, in the inner chamber of left and right plate rail and cylinder pipe, bluff body is housed all, left and right plate rail and cylinder pipe are telescopic wire netting tubular construction, one end of right plate rail links to each other with union joint, and the top of left plate rail is recessed gradually to the centre by both sides, forms " leaves " shape.
Described left and right two plate rails are not parallel, and left plate rail is plate rail inclination to the right gradually from bottom to top, and the spacing of two plate rail webs is up-narrow and down-wide.
This utility model will place the top of left plate rail of left ventricle side recessed down in the ventricular septal defect blocking apparatus, its recess then can be avoided important adjacent tissues such as aortic valve.Because left and right plate rail is not parallel, left plate rail top web and right plate rail web place thin membranous part, and the web of bottom apart from each other place thicker pars muscularis, makes it to have the good stifled effect of closing at a distance of nearer.And upper angled, also make them a little from the aortic valve distance, avoid damage to aortic valve, also avoided the left and right plate rail of closing stopper to protrude in chamber, interventricular septum left and right sides side.
The beneficial effects of the utility model are: this utility model ventricular septal defect blocking apparatus both can be used for muscular ventricular septal defect, also can be used for common membranous ventricular septal defect, can stifled close polytype ventricular septal defect, stifled close respond well, easy for operation, thus make interventional therapeutic technique can in the treatment of ventricular septal defect, obtain extensive clinical practice.
Description of drawings
Fig. 1 is the structural representation of this utility model ventricular septal defect blocking apparatus

The specific embodiment
Below in conjunction with drawings and Examples this utility model is further specified
Illustrated in figures 1 and 2 is an embodiment of this utility model ventricular septal defect blocking apparatus, and this ventricular septal defect blocking apparatus comprises left plate rail 1, right plate rail 2, cylinder 3, bluff body 4 and union joint 5.Left side plate rail places the left ventricle side, and right plate rail places the right ventricle side.The top of left side plate rail 1 is recessed gradually to the centre by both sides, forms " leaves " shape, and right plate rail is circular.Left and right two plate rails are not parallel, and left plate rail 1 is plate rail inclination to the right gradually from bottom to top, and the spacing of two plate rail webs is up-narrow and down-wide.Human body left and right ventricles interventricular septum membranous part up is thin to be 2-3mm, below pars muscularis thicker be 4-5mm.The web narrower part (2-3mm) of this utility model closing stopper places thin membranous part side, and web wide portions (4-5mm) then places thicker pars muscularis side, and middle waist closes rejected region for stifled, and its diameter is φ 4-10mm.Left side plate rail 1 and right plate rail 2 are connected with cylinder 3 two ends respectively, and the other end of right plate rail links to each other with union joint 5.Left and right plate rail and cylinder pipe are telescopic wire netting tubular construction.In the inner chamber of left and right plate rail and cylinder pipe bluff body 4 is housed all, the bluff body 4 in the present embodiment is the medical polyester flake of surgical repair ventricular septal defect, to guarantee its excellent biological compatibility.
The operating process of this utility model ventricular septal defect blocking apparatus is as follows: the induction system of ventricular septal defect blocking apparatus is by carrying long sheath, delivery conduit, the short sheath of guiding to form.The external screw thread of delivery conduit one end links to each other with the female thread of the union joint of interventricular septum closing stopper, the other end of delivery conduit is contained in the short sheath of guiding, by guiding short sheath closing stopper is sent into the long sheath of conveying, carry long sheath closing stopper to be sent into heart by vein blood vessel, guide to the ventricular septal defect position, and block with closing stopper.Again delivery conduit is twisted in the other direction, the screw thread of conduit and closing stopper is unclamped and break away from,, finish treatment again with delivery conduit and carry long sheath to withdraw from human body.This utility model closing stopper is safe and effective, easy and simple to handle, easily reclaims.
