Thrombectomy device and thrombectomy system for aorta and branch arteries thereof

Abstract

The invention provides a thrombectomy device and a thrombectomy system for aorta and branch arteries thereof and belongs to the field of medical instruments. The thrombectomy device for aorta and branch arteries thereof comprises a guide tube, a guide wire tube, a sheath and a collection assembly, wherein the guide wire tube penetrates through the guide tube, and the front end of the guide wire tube extends out of the guide tube; the collection assembly is arranged at the front end of the guide wire tube and comprises a filter net sleeve arranged on the guide wire tube, an elastic ring and binding wires; the net bottom of the filter net sleeve is arranged on the outer wall of the guide tube, and the net opening of the filter net sleeve surrounds the elastic ring; one ends of multiple binding wires are connected with the elastic ring, and the other ends penetrate through the guide wire tube to be led to the outside of the guide wire tube; and the sheath is arranged on the outer side ofthe guide tube and can move in the length direction of the guide tube so as to retract or release the collection assembly. The thrombectomy device can cooperate with a thrombectomy balloon assembly totake out tumor embolus and effectively prevent the risk of far-end embolism in a thrombectomy process.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a thrombus removal device and a thrombus removal system for an aorta and its branch arteries. Background technique [0002] Embolic lesions of the aorta and its primary branches have always been a difficult point in vascular surgery. The minimally invasive thrombus aspiration method can extract acute thrombus, but it cannot deal with subacute and chronic thrombus, let alone tumor thrombus, and there is a risk of thrombus easy to fall off and cause remote embolism; minimally invasive catheter thrombolysis method It can dissolve acute thrombus and some subacute thrombus, but it cannot deal with tumor thrombus, and there is a high risk of bleeding and the risk of distal embolism caused by thrombus falling off. [0003] In summary, it is difficult to deal with tumor thrombi in the prior art, and there is a risk that the thrombus is easy to fall off during thrombectomy, resulting in di...
