Adjustable bicuspid valve forming device

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 [0001] The invention belongs to the technical field of heart valve medical devices, in particular to an adjustable mitral valve shaping device. Background technique [0002] Mitral regurgitation (MR) is one of the most common heart diseases. Mitral valve plasty (MVP) is the preferred surgical treatment for MR, and the use of mitral valve plasty ring during the operation can significantly improve the success rate and durability of MVP. However, residual and / or recurrent MR after MVP has always been a clinical problem for cardiac surgeons. It is often necessary to perform valvuloplasty or valve replacement again, which not only increases the economic burden, but also causes greater pain to the patient, and the risk of the second operation is significantly higher than that of the first operation. Past experience has shown that the main cause of residual MR is the inappropriate selection of the mitral annuloplasty ring size, often due to the size being too larg...

Problems solved by technology

It is often necessary to perform valvuloplasty or valve replacement again, which not only increases the economic burden, but also causes greater pain to the patient, and the risk of the second operation is significantly higher than that of the first operation

Past experience shows that the main cause of residual MR is the inappropriate choice of mitral annuloplasty ring size, often due to the size of the ring being too large and resulting in insufficient leaflet coaptation area
