Embodiment Construction

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0044] The core of the present invention is to provide a thrombus remover, which can improve the success rate of operation and the efficiency of thrombus removal.

[0045] In a specific embodiment of the thrombus remover provided by the present invention, please refer to figure 1 and figure 2 , including a bolt-removing member 3 and a mandrel 1 . The thrombus removal part 3 is self-expandable, and can shrink to make the volume smaller or release to make the...

Abstract

The invention discloses a thrombus remover, comprising: a thrombus remover, the thrombus remover has self-expandability; a mandrel, the thrombus remover is connected to the mandrel, and the mandrel is used to drive the thrombus remover from the blood vessel to the side of the thrombus The entry wound on the other side is moved to the removal wound on the other side, so that the thrombus can be driven by the thrombus removal part to move out from the removal wound. In the thrombus remover in this application, the entrance and exit of the thrombus removal part are different, and it is only necessary to set the mandrel connected to the thrombus removal part to push the thrombus removal part to pass through the thrombus. When the released thrombus removal part reaches the thrombus After removal, continue to move in the original direction, and the thrombus will move together with the thrombus removal piece until the thrombus is taken out from the removal wound by the thrombus removal piece. For the diseased segment of the long thrombus segment, the mandrel is easier to pass through, which increases the passing rate of the thrombus retriever through the thrombus, can improve the efficiency of thrombus removal, and can improve the success rate of the operation.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a thrombus retriever. Background technique [0002] Intravascular embolism is a common clinical and frequently-occurring disease, which refers to the abnormal coagulation of blood in blood vessels. The coagulation reason can be external inducing factors or genetic factors. Thrombosis often occurs in the human body, and the emboli formed in the blood of the human body can cause partial or complete blockage of the blood vessel, hindering the blood supply to the distal end of the blood vessel. The formed thrombus may also fall off, block the blood vessels in other parts with the blood flow, cause ischemia and hypoxia in the corresponding parts of the tissue and organ, and eventually lead to pathology such as tissue or organ necrosis and edema. [0003] Clinically, there are different treatment methods depending on the location of the thrombus and the severity of the thr...
