Abstract

The invention relates to an embolus collection device, an embolus protection system and an embolus collection method. The embolus collection device comprises a near-end connecting piece, a first supporting element comprising a plurality of supporting rods arranged around an axis, wherein at least part of the supporting rods are bent to form a concave face facing the axis, each supporting rod is provided with a first near end and a first far end, and the first near ends are arranged on the near-end connecting piece after being folded; and a first filter element disposed on the first support element and having a second proximal end and a second distal end, wherein the second proximal end being disposed on the first proximal end, the second distal end forming an opening. The device has the advantages that embolism is effectively prevented from entering brain blood vessels and downstream blood vessels, and interference is not caused when surgical instruments enter and exit the blood vessels.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an embolus collection device and an embolism protection system. Background technique [0002] In cardiac surgery, cardiopulmonary bypass, catheter-based interventional cardiac surgery, ascending aortic surgery, and other procedures involving the heart and aorta, surgical instruments can generate platelet aggregates (e.g., embolism, grease droplets, bacterial clots, tumor cells or other small pieces of tissue) or atherosclerotic fragments and debris that are detached from the arterial wall during the operation are sent into the cerebral blood circulation and other important systemic arterial systems with the blood flow to become embolic substances. Embolic material entering the blood circulation of the brain can block small arteries and cause localized cerebral vascular embolism (causing a stroke), which has become a common complication of heart and aortic surgery. Emboli...
