Abstract

The invention provides a device and an assembly for removing foreign matter in a blood vessel. The device for removing the foreign matter in the blood vessel comprises a support body and a fluff assembly, wherein the support body is of a net-shaped pipe structure, the fluff assembly is arranged on the support body and comprises at least two fiber units, and each fiber unit is fixedly connected with the support body. According to the device and the assembly for removing the foreign matter in the blood vessel, the fluff assembly can be used for capturing the foreign matter, escape and residues of the foreign matter are effectively prevented, and therefore a better foreign matter removing effect is achieved.

Description

technical field [0001] The present disclosure relates to the field of medical devices, in particular to a device and component for removing foreign bodies in blood vessels. Background technique [0002] In my country, acute stroke is the third leading cause of death and the first leading cause of disability. According to statistics, there are about 2 million new strokes in the country every year, of which ischemic stroke accounts for about 85% of all patients. [0003] Once acute ischemic stroke occurs, how to quickly remove the thrombus blocking the blood vessel is the key to the success of the treatment. There are two conventional treatment methods. The first is to eliminate thrombus with thrombolytic drugs; the second is to remove thrombus mechanically The device removes the thrombus. Arterial and venous thrombolysis is a routine method for the treatment of acute ischemic stroke, but this method has high requirements on the treatment time window. It is strictly required...
