Description

Technical Field

[0001] This utility model relates to the field of thrombectomy technology, and more specifically, to a thrombectomy support and device. Background Technology

[0002] Thrombectomy is the surgical procedure to remove a blood clot from a blood vessel, a treatment for thrombosis. This interventional procedure removes the clot from the vessel to restore normal blood flow. Thrombectomy is suitable for various conditions, including deep vein thrombosis, pulmonary embolism, and other thrombosis-related diseases such as cerebral thrombosis and cardiac thrombosis. Specifically, the procedure involves anesthesia, catheterization, and guidewire guidance to remove the clot from the blood vessel. In the treatment of acute ischemic stroke, thrombectomy is an important endovascular treatment method that mechanically removes the clot and restores vascular patency.

[0003] A search revealed an existing patent (publication number: CN209474728U) that discloses a thrombectomy stent. This stent includes an expandable mesh lumen comprising a proximal portion, a mid-section portion, and a distal portion connected sequentially. The mesh openings in the mid-section portion are all of the same size; the mesh openings in the proximal portion are larger than those in the mid-section portion; the mesh openings in the distal portion are smaller than those in the mid-section portion; and the distal portion is covered with a mesh film, the mesh openings of which are smaller than those in the distal portion. This invention helps prevent thrombi in the thrombectomy stent from slipping and flowing distally into the blood vessel, thereby improving thrombus removal efficiency.

[0004] The device uses a mesh membrane to expand and remove blood clots. However, if the doctor operates it improperly in an emergency, the mesh membrane may expand excessively, causing its bulging structure to damage the inner wall of the blood vessel and resulting in irreversible damage to the patient. Utility Model Content
