Implant and adjustable wire locking device

Abstract

The invention relates to an implant and an adjustable wire locking device. The implant comprises a shell assembly, a winding piece and a retainer. An opening is formed in the near end of the shell assembly; the winding piece is installed in the shell assembly, and the near end of the winding piece is movably arranged in the opening in a penetrating mode. The retainer is connected with the shell assembly, and a first limiting piece is arranged at the near end of the retainer; wherein the far end of the winding piece is far away from or close to the near end of the retainer, so that the first limiting piece is separated from the winding piece, or the first limiting piece is matched with the far end of the winding piece in an inserted mode. The adjustable wire locking device comprises the implant. According to the implant and the adjustable suture locking device, the suture winding degree can be adjusted in real time, so that the suture locking degree is proper.

Description

technical field

[0001] The present application belongs to the technical field of medical devices, and in particular, relates to an implant and an adjustable wire locking device. Background technique

[0002] Annulus dilatation, one of the most common causes of heart valve disease, can cause the valve leaflets to separate from each other during ventricular systole, creating gaps that can no longer close or coapt effectively, resulting in blood regurgitation and reduced blood output from the heart .

[0003] Annuloplasty for annular expansion is an important procedure for mitral or tricuspid valve repair. The tricuspid valve orifice area is reduced to allow the leaflets to conform to each other during ventricular systole, thereby reducing or eliminating regurgitation. Although surgical annuloplasty can repair the valve annulus well, it has disadvantages such as large trauma, high risk, and slow patient recovery. In recent years, transcatheter minimally invasive intervention...
