Problems solved by technology
When the pushing device reaches the implantation site through the tortuous path of the human body, its main body will produce one or more local bends due to conforming to the path of the human body, and the farthest end of the pushing device will therefore accumulate a certain amount of potential energy, which will affect the implanted device connected to it. A certain push or pull force is generated. At this time, the shape of the implanted device observed by the operator on the medical imaging equipment is formed under the influence of the external force of the push device. After the push device is detached, the elimination of the above push or pull force may lead to sealing. The displacement or deformation of the occluder, once the occluder is found to be abnormally installed, the pushing device cannot be reconnected to the occluder
In the prior art, when the shape of the occluder is abnormal, the shape of the occluder can only be adjusted through open thoracotomy, which is cumbersome and very risky

Embodiment Construction
[0055] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will briefly introduce the drawings that need to be used in the description of the embodiments or the prior art. Obviously, the accompanying drawings in the following description are only These are some embodiments of the present invention. Those skilled in the art can also obtain other drawings based on these drawings without creative work.
[0056] As a specific example, such as Figure 1-3 As shown, an occlusion system includes: an occluder 1, including an occluder body 11 and a connection structure 12, the occluder body 11 and the connection structure 12 can be connected by welding, screw fixing, etc. It is sufficient that the connection structure 12 does not fall off after being used for a long time. The connection structure 12 is arranged in the middle of the bottom of one side of the occluder 1. In actual production, the connecti...

The patent of the present invention discloses a occlusion system, comprising: an occluder, including a occluder body and a connection structure, the occluder body is connected to the connection structure; a pushing device, which is provided with a through inner cavity The push device is detachably connected to the connection structure; the guide is detachably connected to the connection structure through the inner cavity; when the push device is separated from the blocking member, the push device It can be moved to a position where it can be connected with the connection structure under the guidance of the guide piece. This patent adopts a pushing device that penetrates the inner cavity, and a guide that passes through the inner cavity and is connected with the occluder. When the placement position or shape of the occluder is different, the pushing device can be guided by the guide to move to In a suitable position, the pushing device can be reconnected with the occluder to adjust the position and state of the occluder.
Description
technical field [0001] The invention relates to the field of interventional therapy and occluder, in particular to an occlusion system. Background technique [0002] Occluder is a commonly used implant in interventional therapy. It can be used for the prevention or treatment of various heart and brain diseases, such as congenital heart diseases such as atrial septal defect and ventricular septal defect, or for the prevention of stroke. Left atrial appendage occlusion, etc. The occluder needs to be transported in the sheath to the vicinity of the occluded area, and then pushed to the implantation position with a push device and the shape of the occluder adjusted. Install status. When the pushing device reaches the implantation site through the tortuous path of the human body, its main body will produce one or more local bends due to conforming to the path of the human body, and the farthest end of the pushing device will therefore accumulate a certain amount of potential en...
