Abstract

The invention belongs to the technical field of medical equipment, and particularly relates to a closure device. The closure device comprises a sealing part and a fixing part, the fixing part comprises a plurality of supporting rods and at least one anchor thorn arranged on at least one supporting rod, a first end of each anchor thorn is fixed to the corresponding supporting rod, a second end of each anchor thorn faces the outside of the fixing part, wherein at least one anchor thorn is provided with at least one limiting piece, and the outer diameter of the part, located between the second end and the limiting piece, of the anchor thorn is smaller than that of the limiting piece. According to the closure device of the invention, at least one limiting piece is arranged on at least one anchor thorn, and the outer diameter of the part, located between the second end and the limiting piece, of the anchor thorn is smaller than that of the limiting piece, when the anchor thorn pierces the inner wall of the left auricle, the limiting piece on the anchor thorn can effectively limit the piercing depth of the anchor thorn, so that pericardial effusion and other problems caused by the situation that the anchor thorn pierces through the inner wall of the left auricle due to the excessively high piercing depth of the anchor thorn are solved, and the possibility of medical negligence is reduced.

Description

technical field [0001] The invention belongs to the technical field of interventional medical devices, and in particular relates to a blocking device. Background technique [0002] Using interventional methods to treat diseases through catheter technology is currently using more and more treatment methods. Catheter interventional therapy can place various materials, instruments and drugs to the heart and arteriovenous blood vessels of the human body. [0003] Such as the placement of occlusion devices (such as atrial septal defect (ASD) occlusion device, ventricular septal defect (VSD) occlusion device, patent ductus arteriosus (PDA) occlusion device, patent foramen ovale (PFO) Closure device, etc.) to the defect site of the heart, and seal the defect to treat congenital heart disease. This is a device with relatively mature applications. Through the connection between the device and the pusher, the pusher transports it to the predetermined site, and then disconnects the co...
