The invention discloses a cardiac valve repair
system. The
system comprises at least two suture lines, a
suture line implanting device and a
suture line knotting device, wherein the
suture line implanting device is used for implanting the suture lines into different valve leaflets of a cardiac valve, and the suture line knotting device is used for fixing the suture lines together. The suture lineimplanting device comprises a pushing guide
pipe, a clamping component used for clamping the valve leaflets and a
puncturing component used for
puncturing the valve leaflets. The suture line knottingdevice comprises a suture line lock catch used for fixing the suture lines, a lock catch pushing device detachably connected with the suture line lock catch, and a pushing control device used for controlling the suture line lock catch to fix and release the suture lines. According to the
system, the suture lines are implanted into the anterior lobe and the posterior lobe of the
bicuspid valve respectively, then the suture lines are fixed together, and the gap in the
bicuspid valve is reduced or eliminated, so that the
bicuspid valve is prevented from forming two holes, mitral regurgitation istreated, the operation process is simple, the operation cost is low, the trauma degree of a patient is low, the complication risk is low, and the
recovery process is relatively quick.
