Description

technical field

[0001] The invention relates to the technical field of medical devices, in particular to an anti-embolism protection device and a medical device. Background technique

[0002] During some procedures involving the heart and aorta, such as cardiac surgery, cardiopulmonary bypass, catheter-based interventional cardiac surgery, and aortic surgery, surgical instruments cause blood to form platelet aggregates (such as emboli debris, grease droplets, bacterial clots and / or other foreign bodies, tumor cells, or other small pieces of tissue) or atheroma debris and debris that break off from the artery wall and travel through the bloodstream into the bloodstream of the brain Circulation and other important systemic arterial systems become embolized material. Embolic substances entering the blood circulation of the brain will block arterioles, leading to local cerebral vascular embolism. Currently, cerebral vascular embolism has become an important complication of hear...
