Abstract
The invention relates to an adjustable bicuspid valve forming device. The adjustable bicuspid valve forming device comprises an annulus body, a right metal wire and a left metal wire. After a flexible pipe is bent, two ends of the flexible pipe are connected to form the annulus body. The connecting position of the annulus body is divided into a right end and a left end. Two holes are formed in the middle of the annulus body and connected with a left catheter and a right catheter respectively. One end of the left metal wire is fixed on the inner side of the left end, and the other end of the left metal wire penetrates through the connecting position of the two ends of the annulus body to penetrate into the right end and penetrate out from the right catheter. One end of the right metal wire is fixed on the inner side of the right end, and the other end of the right metal wire penetrates through the connecting position of the two ends of the annulus body to penetrate into the left end and penetrate out from the left catheter. The left end is sleeved into the right end or the right end is sleeved into the left end. Inverted hook-shaped teeth are arranged on an opposite surface of the connecting position of the left end and the right end. According to the adjustable bicuspid valve forming device, secondary thoracotomy does not need to be conducted, an annular inner diameter is adjusted through an adjusting handle so that a prospective result can be obtained, pain of mind and body and economical burden of a patient can be relieved, and complication of the secondary operation can be avoided, and the mortality rate of the secondary operation can be reduced.
Description
Technical field
The invention belongs to the cardiac valve technical field of medical instruments, particularly relate to a kind of adjustable mitral valvuloplasty device.
Background technology
(mitral regurgitation MR) is one of modal heart disease to mitral incompetence.(mitral valve plasty is the surgical intervention method of MR first-selection MVP) to plastic surgery for mitral valve, uses the mitral valvuloplasty ring can significantly improve success rate and the durability of MVP in the art.But the MVP postoperative is residual and/or recurrence MR is puzzlement cardiac surgeon's a clinical difficult problem always.Often need to go again valvoplasty or prosthetic valve replacement, this not only increases financial burden, also can cause bigger misery to the patient, and the risk of second operation is apparently higher than operation for the first time.In the past experience shows that the main cause of residual MR is that ring-like number selection of mitral valvuloplasty is improper, and model is bigger than normal and cause the involutory area deficiency of lobe leaf often.
Summary of the invention
Technical problem to be solved by this invention provides a kind of adjustable mitral valvuloplasty device, at the tinsel of the built-in two mutual buckles of traditional forming ring, can unidirectionally relatively move between this two one metal wire, thereby the forming ring internal diameter is diminished.
The technical solution adopted for the present invention to solve the technical problems is: a kind of adjustable mitral valvuloplasty device is provided, comprise ring body, right tinsel and left tinsel, described ring body by a flexible pipe bending after two ends link to each other and to form, described ring body junction is divided into right-hand member and left end, described ring body middle part has 2 holes, connect left conduit and right conduit respectively, described left tinsel one end is fixed on the inwall of left end, the other end passes junction, ring body two ends and penetrates right-hand member and pass from right conduit, described right tinsel one end is fixed on the inwall of right-hand member, the other end passes junction, ring body two ends and penetrates left end and pass from left conduit, described left end is inserted in right-hand member or right-hand member is inserted in left end, have barb-shaped tooth on the opposite face of the junction of described left end and right-hand member, described right tinsel and left tinsel are connected guide wire respectively after passing left conduit and right conduit respectively.
Described left conduit and right conduit and ring body are single piece.
Described left conduit and right conduit and ring body are made by macromolecular material.
Beneficial effect
The invention has the advantages that tinsel is connected with guide wire, pass through the interatrial septum, lead to outside the skin through femoral vein or jugular vein again that the outer end connects regulating handle.After the operation, transesophageal ultrasonography is estimated the effect of MVP, if forming effect is dissatisfied, the forming ring model is excessive.Do not need open chest surgery again, only need to adjust through regulating handle the internal diameter of forming ring, can obtain expected effect.By this method, both can alleviate patient's body and mind misery and financial burden, can avoid complication and the mortality rate of second operation again.
