Abstract

The invention relates to an anti-embolism protection device and a medical instrument. The anti-embolism protection device comprises a supporting frame and a filtering piece, the supporting frame comprises a main body part, a first supporting part and a second supporting part, the first supporting part and the second supporting part are connected with the far end of the main body part, the first supporting part is located below the second supporting part, in the unfolded state, the first supporting part is bent towards the lower portion of the main body part, and the filtering piece covers themain body part and the second supporting part. The anti-embolism protection system and the medical instrument are good in coverage and high in stability.

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...
