Embodiment 1
[0025] As shown in Figure 1, the present invention provides a safety device for preventing cardiac implants from falling off, which is a safety rope made of degradable silk thread, the specification of the safety rope is 6-0, and the wire diameter is 0.095-0.149 mm, tensile strength ≥ 2.5N.
[0026] When the above-mentioned safety device for preventing cardiac implants from falling off is used in transthoracic interventional surgery in cardiac surgery, the safety device 3 is first inserted from one side of the cardiac implant device 2, that is, the occluder, wrapped around it, and passed through from the other side. Come out and fix on the occluder (such as Figure 1a shown), the distances from both ends of the safety device 3 to the fixed point of the occluder are the same, and the safety device 3 fixed on the occluder follows the occluder, using the cardiac implant delivery device 4, and the delivery of the occluder The sheath is implanted at the defect site, and after the o...
Embodiment 2
[0029] As shown in Figure 1, the present invention provides a safety device for preventing cardiac implants from falling off, which is a safety rope made of degradable silk thread, the specification of the safety rope is 2-0, and the wire diameter is 0.340-0.399 mm, tensile strength ≥ 26.8N.
[0030] When the above-mentioned safety device for preventing the heart implant device from falling off is used in transapical interventional surgery in cardiac surgery, the safety device 3 is first penetrated from one side of the heart implant device 2, that is, the valve stent, wound around it, and passed out from the other side. fixed on the valve support (such as Figure 1b shown), the distances from the two ends of the safety device 3 to the fixed point of the valve support are the same, the safety device 3 fixed on the valve support is delivered with the valve support, and then the two ends of the safety device 3 are sewn on the outer surface of the apex of the heart 1 on the myoca...
