本发明公开了一种封堵器及封堵装置,包括网状带有空腔的封堵本体和近端栓头,近端栓头具有与空腔贯通的锁定孔,封堵器还包括锁定件,锁定件的远端与封堵本体的远端
相接,锁定件为弹性件,锁定件包括与封堵本体连接的连接部以及第一弯折部,具有第一弯折夹角,第一弯折部在垂直于其长度方向上的横截面上的投影的外接圆的直径小于
锁定孔的最小内切圆的直径,第一弯折部在锁定孔的纵向中心轴方向垂直的平面上的投影宽度大于锁定孔的最大内切圆的直径。本发明结构简单,锁定件尺寸易于控制,方便
加工,简化了制备工艺和锁定操作,同时锁定件的锁定可靠性高,不易失效,锁定操作过程可逆,锁定过程和回收过程均简单易行。
An occluder and an occlusion device, including: a mesh occlusion body, which defines a cavity, and a proximal end bolt head; the proximal end bolt head configured with
a locking hole which penetrates the cavity; the occluder further having a locking member, a distal end of the locking member being connected to a distal end of the occlusion body;the locking member having a connecting portion which is connected to the occlusion body; the diameter of a circumscribed circle of a projection of the
first bending portion on across section perpendicular to a length direction thereof being smaller than the diameter of the smallest inscribed circle of a locking hole,
cross section perpendicular to a length direction thereof being smaller than the diameter of the smallest inscribed circle of a locking hole, being larger than the diameter of
the largest inscribed circle of the locking hole
