Abstract

The invention relates to a thrombus extraction device for pulmonary artery embolism. The thrombus extraction device comprises a thrombus extraction net rack; the thrombus extraction net rack is connected with the left end of a pushing guide wire through welding; the right end of the pushing guide wire is arranged on a guide wire twister; the pushing guide wire is sleeved with a micro catheter in a sliding mode; the micro catheter is sleeved with a middle catheter in a sliding mode; the middle catheter is sleeved with a guide catheter in a sliding mode; the micro catheter is connected with a first Y-shaped connector through a Luer taper; the middle catheter is connected with a second Y-shaped connector through a Luer taper; the guide catheter is connected with a third Y-shaped connector through a Luer taper; the guide catheter is connected with a first injector through a three-way valve and the third Y-shaped connector; the middle catheter is connected with a second injector through the three-way valve and the second Y-shaped connector; and a thrombus extraction net rack protective sleeve is arranged on the thrombus extraction net rack in a sleeving mode. According to the thrombus extraction device, the thrombus extraction device can be better matched with a blood vessel in size and more firmly embedded with thrombus, and newly-formed acute and old thrombus can be taken out.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a thrombectomy device for pulmonary embolism. Background technique [0002] Most of the thrombectomy grids in the existing market are used to treat intracranial thrombus, for example: the "intracranial thrombus removal device" disclosed in Chinese patent CN203379185U, the intracranial thrombus removal device includes a radial expansion and contraction thrombectomy grid, using At the same time, the thrombus retrieval grid is placed in the microcatheter, the thrombus retrieval grid is connected with the guide wire, the microcatheter is sent to the thrombus site, and then the microcatheter is removed, and the thrombus retrieval grid is released and embedded without the restriction of the microcatheter into the thrombus to form a retention force with the thrombus, and then pull the guide wire to remove the thrombus retrieval grid from the blood vessel, and the thr...
