Device for removing emboli of cerebral embolism

Abstract

The invention discloses a device for removing emboli of cerebral embolism. The device comprises a puncture device (1) and a embolus removing apparatus (2). The puncture device (1) is used for reachingfocus locations along the extension directions of blood vessels to provide channels for the embolus removing apparatus (2) for removing the emboli of the embolism, the embolus removing apparatus (2)is used for fixing the emboli of the embolism and removing the emboli along the extension directions of the puncture device (1) and comprises a removing apparatus front end (21), an embolus removing apparatus catheter (22) and an embolus removing apparatus operating end (23), the removing apparatus front end (21) is used for being screwed into the emboli of the embolism and fixing the emboli of the embolism, the embolus removing apparatus catheter (22) is used for driving the removing apparatus front end (21) to synchronously rotate when the embolus removing apparatus operating end (23) rotates, and the embolus removing apparatus operating end (23) is used for providing power for the removing apparatus front end (21) during rotation. The device has the advantages that the emboli of the embolism can be effectively fixed and removed by means of distal synchronous operation, accordingly, the surgical safety can be effectively improved, and the surgical success rate can be effectively increased.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a device for removing emboli from cerebral embolism. Background technique [0002] Cerebral embolism (cerebral embolism) is also called embolic cerebral infarction (embolic infarction). Refers to certain abnormal solid, liquid or gas embolic substances in the blood circulation of the human body, which enter the cerebral arteries or the carotid arteries supplying the brain with the blood flow, causing acute occlusion of the vascular lumen, causing local cerebral blood flow interruption, resulting in local cerebral arteries. Tissue ischemia, hypoxia, or even softening and necrosis lead to clinical manifestations of acute brain dysfunction. [0003] According to the source of emboli, the etiology can be divided into: cardiogenic, non-cardiac, and unknown sources. The main treatment methods include intra-arterial thrombolysis, mechanical thrombectomy, and emergency angiopla...

AI Technical Summary

Problems solved by technology

[0006] The Penumbra device is a thrombus suction device. Its suction force is difficult to control. If the force is too high, it may cause convulsions. If the force is too small, the thrombus cannot be sucked

[0007] The Solitaire AB stent device is a self-expanding stent, which is more flexible than the ball-expandable stent, but it may cause pressure on the vessel wall, causing spasm so that it cannot be removed from the body, and it grasps the thrombus by expansion force, only touching the surface of the thrombus instead of embedded inside , the contact area is small, and the thrombus is easy to escape
