Abstract

The invention relates to a thrombus taking device. The thrombus taking device comprises a thrombus taking support, a thrombus breaking support and a conveying assembly, wherein the thrombus taking support and the thrombus breaking support are of support structures capable of contracting and expanding; the far end of the conveying assembly is connected with the thrombus taking support and the thrombus breaking support and used for containing the thrombus taking support and the thrombus breaking support which are in a contracting state; and the conveying assembly can release the thrombus taking support and the thrombus breaking support to an expanding state and can drive the thrombus breaking support to move in the internal space of the thrombus taking support in the expanding state in the axial direction of the thrombus taking support. According to the thrombus taking device, the thrombus taking support is matched with the thrombus breaking support, when the thrombus taking support contains thrombus in blood vessels in the thrombus taking support, the conveying assembly controls the thrombus breaking support to stretch into the internal space of the thrombus taking support, and the thrombus breaking support can move in the axial direction relative to the thrombus taking support to cut the thrombus; and therefore, the thrombus in the thrombus taking support is continuously cut and broken; the intractable, large and hard thrombus can be easily broken, and the thrombus taking effect is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a thrombus removal device. Background technique [0002] Venous thromboembolism (VTE) includes deep vein thrombosis (DVT) and pulmonary embolism (PE). [0003] Deep vein thrombosis (DVT) of the lower extremities is a high-incidence vascular surgical disease, which is mostly caused by abnormal coagulation of blood in the veins of the lower extremities, resulting in obstruction of blood return. Pulmonary embolism (PE) has become the third leading cause of cardiovascular death. Risk factors for pulmonary embolism include both environmental and personal factors. Personal factors include age, previous VTE history, cancer history, cardiopulmonary failure, congenital or acquired coagulation disorders, and hormone therapy. Acute PE can lead to systemic hypotension and even heart failure, which can lead to patient death. [0004] Therefore, early, rapid and effective thrombus r...
