Abstract
The present invention relates to a kind of adjustable mitral valvuloplasty device, comprise ring body, right tinsel and left tinsel, after described ring body is bending by a flexible pipe, two ends are connected forms, described ring body junction is divided into right-hand member and left end, 2 holes are had in the middle part of described ring body, connect left conduit and right conduit respectively, described left tinsel one end is fixed on the inwall of left end, the other end penetrates right-hand member through junction, ring body two ends and passes from right conduit, described right tinsel one end is fixed on the inwall of right-hand member, the other end penetrates left end through junction, ring body two ends and passes from left conduit, described left end is inserted in right-hand member or right-hand member is inserted in left end, with barb-shaped tooth on the opposite face of the junction of described left end and right-hand member.The present invention does not need open chest surgery again, only need adjust the internal diameter of forming ring through regulating handle, can obtain expected effect, both can alleviate body and mind misery and the financial burden of patient, can avoid again complication and the mortality rate of second operation.
Description
Technical field
The invention belongs to cardiac valve technical field of medical instruments, particularly relate to a kind of adjustable mitral valvuloplasty device.
Background technology
Mitral incompetence (mitral regurgitation, MR) is one of modal heart disease.Plastic surgery for mitral valve (mitral valve plasty, MVP) is the methods of surgical of MR first-selection, uses mitral valve forming ring can significantly improve success rate and the durability of MVP in art.But MVP Postoperative Residual and/or recurrence MR are clinical problem of puzzlement cardiac surgeon always.Often need row valvoplasty or prosthetic valve replacement again, this not only increases financial burden, also can cause larger misery to patient, and the risk of second operation is apparently higher than first time operation.Experience display in the past, the main cause of residual MR is that mitral valve forming ring model is selected improper, and model is bigger than normal and to cause the involutory area of lobe leaf not enough often.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of adjustable mitral valvuloplasty device, at the tinsel of the built-in two mutual buckles of traditional forming ring, can unidirectional relative movement between this two one metal wire, thus forming ring internal diameter is diminished.
The technical solution adopted for the present invention to solve the technical problems is: provide a kind of adjustable mitral valvuloplasty device, comprise ring body, right tinsel and left tinsel, after described ring body is bending by a flexible pipe, two ends are connected forms, described ring body junction is divided into right-hand member and left end, 2 holes are had in the middle part of described ring body, connect left conduit and right conduit respectively, described left tinsel one end is fixed on the inwall of left end, the other end penetrates right-hand member through junction, ring body two ends and passes from right conduit, described right tinsel one end is fixed on the inwall of right-hand member, the other end penetrates left end through junction, ring body two ends and passes from left conduit, described left end is inserted in right-hand member or right-hand member is inserted in left end, with barb-shaped tooth on the opposite face of the junction of described left end and right-hand member, described right tinsel and left tinsel pass left conduit respectively and are connected guide wire respectively with after right conduit.
Described left conduit and right conduit and ring body are single piece.
Described left conduit and right conduit and ring body are made up of macromolecular material.
Beneficial effect
The invention has the advantages that, tinsel is connected with guide wire, passes through interatrial septum, then leads to outside skin through femoral vein or jugular vein, and outer end connects regulating handle.Post operation, transesophageal ultrasonography evaluates the effect of MVP, if forming effect is unsatisfied with, forming ring model is excessive.Do not need open chest surgery again, only need adjust the internal diameter of forming ring through regulating handle, can expected effect be obtained.By the method, both can alleviate body and mind misery and the financial burden of patient, complication and the mortality rate of second operation can be avoided again.
