Valve repair system for implanting artificial chordae tendineae

A valve repair system for implanting artificial chordae tendineae, comprising:

• a handle operation device at a proximal end;
• a valve clamping device at a distal end;
• at least one set of valve puncturing devices at the distal end;
• a catheter connected between the handle operation device and the valve clamping device;
• and
• a grasping-feedback device configured to determine whether a valve is correctly grasped, wherein the valve clamping device comprises a clamping mechanism at the distal end and a clamping-control component connected to the clamping mechanism, the clamping-control component configured to control the clamping mechanism to open or close, the clamping-control component is configured to receive the artificial chordae tendineae, the clamping mechanism comprises a proximal clamp and a distal clamp;
• wherein each of the at least one set of valve puncturing devices comprises a pulling loop configured to pull the artificial chordae tendineae, a connecting component configured to fix the pulling loop, and a puncture needle assembly, the pulling loop and the connecting component are received in the distal clamp;
• the puncture needle assembly comprises a puncture needle and a puncture hollow tube sleeved on the puncture needle, a distal end of the puncture needle assembly is received in the proximal clamp, the puncture hollow tube is detachably connected to the connecting component;
• the handle operation device comprises a handle, a puncturing-operation mechanism received in the handle, a clamping-operation mechanism received in the handle, and a feedback-operation mechanism received in the handle, the puncturing-operation mechanism is connected to the puncture needle assembly, the clamping-operation mechanism is connected to the clamping-control component, and the feedback-operation mechanism is connected to the grasping-feedback device.
