Abstract

The invention provides a thrombus extraction device capable of preventing thrombus from falling off, and relates to the technical field of medical apparatuses and instruments. The thrombus extraction device comprises a delivery tube and a guide wire arranged in the delivery tube; a spherical picking net is fixed to the top end of the delivery tube, a conical cover is arranged at the top end of the delivery tube in an inwards-sunken mode, and the spherical picking net is located in the conical cover at the initial position; and a hole for the guide wire to pass through is formed in the middle of the conical cover, and the top of the guide wire is fixedly connected with the spherical picking net. The thrombus extraction device is easy to operate, thrombus can be prevented from sliding, the thrombus can be completely taken out, and the working efficiency of medical staff is effectively improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a thrombus retrieval device for preventing thrombus from falling off. Background technique [0002] Thrombus is a solid mass formed by coagulation of blood or aggregation of certain formed components in blood in the heart and blood vessels of a living body. In the variable fluid-dependent type, the thrombus is composed of insoluble fibrin, deposited platelets, accumulated white blood cells, and trapped red blood cells. Thrombosis is a multifactorial process in which a set of genetic and environmental factors interact and influence each other. The main characteristics of common clinical thrombosis patients are familial heredity, recurrence, severity of symptoms, abnormal thrombosis site, and younger onset time. [0003] Therefore, in order to prevent the thrombus from falling off and causing more serious harm, the thrombus should be removed in time. The existing thrombus ...
