Abstract
The present application provides a valve annulus contraction surgical system with an adjustable annulus contracting force at a single point, and relates to the technical field of medical devices. The system includes a plurality of anchors, an implantation device, a plurality of groups of locking sutures and a suture locking device. A suture locking tab is arranged on at least one of two sides of each of the anchors. The implantation device is configured to implant the anchors into a valve annulus; each group of locking sutures includes a first locking suture and a second locking suture for connection with the suture locking tab. The suture locking device is configured to lock and fix the other end of the first locking suture and the other end of the second locking suture. In the present application, a valve orifice can be completely covered by a valve, thereby ensuring a therapeutic effect.
