The invention relates to a bifurcation aneurysm occlusion device. The device comprises a supporting part, a connecting part and a blocking part; the blocking part is of a net-shaped structure and can be attached to a neck opening of an aneurysm; one end of the connecting part is fixed to the net face of the blocking part, and the other end of the connecting part is connected with the supporting part; the supporting part is of a hollow tubular structure; and the supporting part can be attached to the inner wall of the blood vessel. After being released, the hollow tubular supporting part can be attached to the inner wall of the bifurcation blood vessel, and the supporting part and the blocking part are connected through the connecting part; the connecting part is located at the fork position of the bifurcation blood vessel, so that the blocking part of the net-shaped structure can be fixed to the neck opening of the aneurysm, dense blocking in the aneurysm is achieved, the problem of bifurcation aneurysm branch occlusion is solved, and the occurrence probability of ischemic complications is reduced; and more specifically, for medical staffs, the device reduces the operation difficulty in the process of implanting instruments into the human body, so that the operation time is shortened, and the operation risk is reduced.
Description
Technical field [0001] The present application relates to the field of medical devices, and more particularly to a branch aneurysm closure device. Background technique [0002] Minimally invasive interventional surgery is a common treatment for vascular aneurysms, which is the same for bifurcated aneurysms. [0003] At present, the main treatment technique of the base artery branch aneurysm has different methods of denseness, bracket auxiliary spring ring dense blocker, and aneurysm blocking device. The objective of the above treatment technique is to achieve the occlusion of the insertion of the pork portion after the implantation of the instrument is implanted. In the above technique, the balloon auxiliary spring ring embolization has a high degree of ability to the balloon, and the spring ring still has the risk of detaching from the tumor after implantation, while the stent assist spring ring embolism, in order to avoid bifurcation Blood vessel occlusion, for the release skil...
