Abstract

The invention relates to a plugging device, which comprises a plugging unit and a plugging head connected with the plugging unit, wherein the plugging unit is provided with a central shaft; and the central shaft penetrates through the far end and the near end of the plugging device. The plugging device also comprises a marking structure, wherein the marking structure comprises a far end marker andat least two first markers; the far end marker is arranged on the plugging head; each first marker is independently connected with the plugging unit; the first markers are positioned in the same placement plane which is vertical to the central shaft; the far end marker is positioned out of the placement plane; a projection point of each first marker in a projection plane vertical to the placementplane is positioned on one straight line segment; and under a natural state of the plugging device, connection lines of the far end marker and two end points of the straight line segment form a triangle. According to the plugging device, a success rate of an implantation surgery can be improved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an occluder. Background technique [0002] In 1974, King and Mills completed the first transcatheter intervention for atrial septal defect (atrial septal defect, ASD). Since then, with the continuous improvement of occlusion devices, especially since 1997, with the Amplatzer nickel-titanium alloy braided With the advent of occluders, nickel-titanium alloy braided occluders are widely used in congenital heart defects such as atrial septal defect (ASD), ventricular septal defect (VSD), patent ductus arteriosus (PDA) and patent foramen ovale (PFO). disease intervention. At present, the minimally invasive treatment of congenital heart diseases such as atrial septal defect (ASD), VSD, PDA and PFO by transcatheter interventional occluder has become an important method. After occluding the heart defect, the tissue around the defect grows inward and completes endothelialization. Non-deg...
