Problems solved by technology

[0002] Atrial septal defect and ventricular septal defect in congenital heart disease are usually repaired by surgery, but the trauma is large, the pain is much, and there are certain risks. In recent years, more and more occlusive umbrellas are used for occlusion, but recently The occlusive umbrella has certain defects and complications. Due to the direct contact of the alloy with the tissue, complications are caused, and the alloy material is prone to form a thrombus when exposed to the blood, and is also prone to conduction block; foreign countries and the Ministry of Health have stopped the production of this product. clinical use

Embodiment Construction

[0016] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0017] see figure 1 The occluder of this embodiment is dumbbell-shaped as a whole, and the occluder is composed of a dumbbell-shaped skeleton support 10 and a sealing film 20 covering the surface of the skeleton support 10 .

[0018] Skeleton support body 10 comprises waist 11 and left disc 12, right disc 13 respectively positioned at the two ends of waist 11, is provided with end 14 at the center of left and right disc 12, 13, among the figure only in right disc 13 The above shows the end 14. The structural components of the skeleton support body 10 can be columnar or mesh-shaped. The skeleton support body 10 constitutes the main structure of the occluder. It should be compatible with the existing occluder. The device is average, with bo...

Abstract

The invention discloses a closure device, which comprises a skeleton supporting body and a sealing membrane which covers the surface of the skeleton supporting body. The sealing membrane integrally forms a sealed bag. The sealing membrane is made of a nylon fabric, a polyester fabric, PTFE (polytetrafluoroethylene), an autologous or heterologous pericardium, an autologous or heterologous artery organic membrane, an autologous or heterologous vein organic membrane or the like. When the closure device is clinically used, the sealing membrane isolates the skeleton supporting body from a human body. Only the sealing membrane is in contact with blood and tissues and metallic materials do not enter the blood and the risk of complications is reduced. Since the sealing membrane is made of the nylon fabric, the polyester fabric, the PTFE (polytetrafluoroethylene), the autologous or heterologous pericardium, the autologous or heterologous artery organic membrane, the autologous or heterologous vein organic membrane or the like, the biocompatibility is good, the human body repulsion is small and the physiological harmfulness is small; and since the sealing membrane is integrally sealed, the situation that thrombus is caused because the blood seeps into the sealing membrane is avoided and the safety in clinical use is improved.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an occluder. Background technique [0002] Atrial septal defect and ventricular septal defect in congenital heart disease are usually repaired by surgery, but the trauma is large, the pain is much, and there are certain risks. In recent years, more and more occlusive umbrellas are used for occlusion, but recently The occlusive umbrella has certain defects and complications. Due to the direct contact of the alloy with the tissue, complications are caused, and the alloy material is prone to form a thrombus when exposed to the blood, and is also prone to conduction block; foreign countries and the Ministry of Health have stopped the production of this product. clinical use. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide an occluder, which can replace the original occluding umbrella and be used in surgical operations o...
