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...

Abstract

The invention discloses a safety device and method for preventing a heart implanting device from shedding and application thereof. The safety device is a safety rope made of degradable threads. When an implanting device sheds or needs to be taken out due to serious complication after a patient receives a surgery, the safety device can fix the implanting device, so that moving of the implanting device under action of blood flow is limited; when the implanting device is taken out, shedding position of the implanting device can be determined according to position of a safety rope, and the safetyrope can be utilized to assist to drag the implanting device into a recycling sheath, so that convenience is brought to capturing the implanting device, and suffering from major injury caused by thoracotomy of the patient is relieved. The safety device can effectively fix the heart implanting device which is more convenient to capture.

Description

technical field [0001] The invention relates to a safety device, a method and an application thereof for preventing a cardiac implant device from falling off, and belongs to the technical field of medical devices. Background technique [0002] Cardiac implantable devices are widely used in clinical practice and can be used to treat various heart diseases, mainly including congenital heart defects, heart valve calcification and regurgitation, atrial fibrillation and other diseases. Congenital heart defect is a common congenital heart disease. At present, the commonly used surgical method is to use an occluder to occlude to achieve the purpose of treatment. The commonly used surgical occlusion methods include medical percutaneous interventional occlusion and surgical Thoracic interventional closure. With the popularization of congenital heart disease occlusion technology, the number of cases of congenital heart disease occlusion treatment in my country is increasing, and the ...
