AI Technical Summary
Technical Problem
Existing thrombus aspiration devices cannot completely remove stubborn thrombi adhering to the blood vessel wall when removing thrombi.
Method used
The device employs a combination of expansion and scraping components. The expansion component expands the filter cartridge to filter thrombi, while the scraping component scrapes away thrombi adhering to the blood vessel wall. Combined with the negative pressure device of the suction tube, the thrombi are completely removed.
Benefits of technology
It achieves complete removal of thrombi within blood vessels and thrombi adhering to the vessel walls, ensuring thorough and safe thrombus removal.

Abstract
This invention discloses a thrombus aspiration and filtration device for interventional therapy, comprising at least a pusher, an external catheter, a suction tube, an inner catheter, a connecting flexible tube, and a thrombus removal mechanism. The pusher is configured as an operating part, the external catheter is disposed at the front end of the pusher, the external catheter is configured as a flexible tube, and there is a certain pushing distance between the external catheter and the pusher. The suction tube is connected to the inner wall of the external catheter, and the inner catheter is connected to the front end of the external catheter. One end of the connecting flexible tube is fixed to the front end of the pusher, and the other end slides through the external catheter and the inner catheter in sequence. The thrombus removal mechanism is disposed at the front end of the inner catheter for completely removing thrombi from the blood vessel. The suction tube is equipped with at least one negative pressure device for aspirating thrombi.
