Anti-falling recyclable safety plugging device

Abstract

The invention relates to an anti-falling recyclable safety plugging device which comprises a bidiscoidal nickel-titanium wire bracket, a screw thread steel bushing, a polyester film and a sewing line. The screw thread steel bushing is arranged on the bidiscoidal nickel-titanium wire bracket; the polyester film is arranged in the bidiscoidal nickel-titanium wire bracket; the screw thread steel bushing is provided with a process slot in a truncated cone shape; the process slot is provided with a through hole; and the sewing line passes through the through hole. The safety plugging device disclosed by the invention solves the problem that an existing plugging device is likely to fall off to cause safety risk; moreover, the safety plugging device realizes that if the plugging device falls off after being separated from a push rod in the minimally invasive or interventional therapy of the congenital heart disease, recycling or regulation of the plugging device can be carried out again; the anti-falling recyclable safety plugging device has a simple structure and is easy to operate; safety risk of an operation is greatly reduced; the admission threshold of the minimally invasive or interventional operation on skills of a doctor is also relatively reduced; and the anti-falling recyclable safety plugging device is beneficial to selection of a patient and popularization of an operation method.

Description

technical field [0001] The invention relates to the field of minimally invasive or interventional medical devices, in particular to a fall-off-preventing and recoverable safety occluder for cardiac septal defects. [0002] Background technique [0003] [0004] Existing medical technology has long been committed to being able to occlude septal defects through minimally invasive or interventional non-traditional operations. The existing main device for transcatheter closure of ventricular septal defect, atrial septal defect and patent ductus arteriosus is a The device used to close atrial septal defect, ventricular septal defect and patent ductus arteriosus is called an occluder. The occluder is in the shape of a double disc. The occluder disc is made of superelastic metal wire and is fed through the catheter. The part of the heart defect, after being pushed out of the catheter, automatically restores the original shape of the design, and is clamped on both sides of the hea...

Problems solved by technology

[0011] The purpose of the present invention is to provide a safety occluder that is anti-falling off and recyclable, which solves the problem that the existing occluder is easy to fall off and causes safety risks, and realizes the occluder and pushing in the minimally invasive or interventional treatment of congenital heart disease. If the rod is detached, the occluder can be recovered or adjusted again. The safety occluder of the present invention has a simple structure and is easy to operate, which greatly reduces the safety risk of the operation and relatively lowers the technical access threshold of the operation. Conducive to the promotion of patients' treatment and surgery
