Abstract: A system for repairing a valve leaflet in minimally invasive surgery includes: a delivery device comprising: an operating handle; an outer delivery tube coupled to the operating handle; a delivery needle coupled to the operating handle; and a pushing tube coupled to the operating handle. The system further comprises a repair component comprising an anchor and a connection wire. The delivery device is configured to perform, in response to a trigger operation, a linkage release operation that includes actuating the delivery needle and releasing the repair component.

Abstract: A repair assembly and a repair assembly implantation device are provided. The repair assembly comprises a first implant, a second implant, and a wire clamping device; the first implant and the second implant each comprises a first fastener, a second fastener, a transverse tube and a locking wire; the first fastener and the second fastener are connected to the transverse tube by means of connecting wires, and the locking wire is connected to the transverse tube; the wire clamping device is configured to clamp the locking wire.

Abstract: Disclosed are a suture locking device and a suture locking device implanting apparatus. The suture locking device comprises a suture pressing housing, a squeezing part and a driving component, wherein a suture pressing cavity is provided inside the suture pressing housing, the squeezing part is arranged in the suture pressing cavity, a first suture routing hole and a second suture routing hole are provided in the housing wall of the suture pressing housing, the driving component is configured to squeeze the squeezing part, and therefore, a locking suture sequentially penetrating the second suture routing hole and the first suture routing hole is squeezed.

Abstract: Provided are fastening nail, fastening nail implanting apparatus and medical instrument, wherein the fastening nail includes a nail seat and a spiral part, wherein front end of the spiral part is formed as a tip, rear end of the spiral part is fixedly connected to front end of the nail seat, and a first positioning part is provided on an end surface of rear end of the nail seat. The fastening nail implanting apparatus implants the fastening nail into a human body and includes a base, a conveying cable and an anchoring handle, wherein rear end of the conveying cable is connected to the anchoring handle, and front end of the conveying cable is provided with a second positioning part; and the anchoring handle is installed on the base, and drives the conveying cable to rotate or release the fastening nail under first working condition or second working condition.

Abstract: The present application provides a valve stent and a prosthetic valve having the same, and belongs to the technical field of cardiac valves. The valve stent comprises a stent body, a positioning ring and elastic connection wires, wherein the positioning ring in a compressed state is adapted to be arranged in series with the stent body sequentially along an axis thereof, and when the positioning ring has elastically deformed from the compressed state to a propped open state, the positioning ring becomes coaxially sleeved on the stent body due to traction of the elastic connection wire. In the valve stent of the present application, after being implanted, the positioning ring can automatically expand to reach the propped open state by elastic deformation, and due to the traction of the elastic connection wire, the positioning ring can become coaxially sleeved on the stent body. Therefore, in the process of an implanting surgery, the positioning ring and the stent body can be positioned at the same time.
