a brain protection system

Abstract

The invention discloses a brain protection system, which relates to the technical field of medical devices. It includes a catheter 1 and a collection assembly 2 for collecting blood clots and emboli, the collection assembly is movably arranged inside the catheter 1, the collection assembly includes a catheter 2, and the inner part of the catheter 2 is movably provided with a catheter 3, the The bottom end of the third conduit is provided with a connecting wire, and the bottom end of the third conduit is provided with a collection net 1, and the collection net 1 is used for intercepting the emboli and blood clots entering the subclavian artery. By setting the collecting assembly, the connecting wire pulls the closing wire 2 through the bending part, so that the two closing wires 2 move relative to each other and fit together, thereby avoiding the disengagement of blood clots and emboli inside the collecting net 2 when the collecting net 2 is taken out. , when the conduit 3 moves upwards, it drives the connecting wire to move upwards, so that the collection net 1 and the collection net 2 are tightened at the same time, which further ensures the collection effect and operation efficiency, and has broad application prospects.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a brain protection system. Background technique [0002] Brain cells have a high demand for oxygen supply. The human brain is mainly supplied by four arteries, including a basilar artery synthesized by two vertebral arteries, and two internal carotid arteries, which are co-injected and redistributed through a circle of Willis. The tissue supplies blood, so a blood supply artery is blocked, and other arteries can have a certain compensatory blood supply. However, when the collateral circulation cannot or is insufficient to compensate, the brain tissue supplied by the blocked artery will produce irreversible ischemic necrosis, that is, cerebral embolism occurs, resulting in partial loss of human body functions, which can be fatal in severe cases. [0003] Specifically, cerebral embolism refers to the blockage of various emboli in the blood (such as mural thrombus in the he...

AI Technical Summary

Problems solved by technology

[0005] At present, most of the existing emboli collection methods use a filter-type cerebral embolism protection device, that is, the filter is placed in a catheter and pushed into the femoral artery at the surgical site, and then the filter is stretched in the femoral artery to protect the emboli. Intercept and recover, but when the filter is taken out, it first touches the catheter, and it is easy to make the blood clots and emboli collected inside re-enter the artery, which cannot be effectively collected, and the use effect is not ideal
