Abstract

The invention relates to an inferior vena cava filter which comprises a filter main body, wherein the filter main body is made of nickel-titanium alloy and can be bound to a loader or can be released and unfolded in a blood vessel; the inlet end of the filter main body is provided with first internal threads connected with a conveyor. The invention aims at providing a simple and convenient inferior vena cava filter which is novel in structure, obvious in effect, easy to fix, accurate to embed, good in thrombus collection effect and less in influence on blood flow and is a novel intervention-type treatment device capable of replacing traditional drug therapy such as anticoagulation and thrombolysis or other surgical operation treatment methods. The invention further provides a preparation method of the inferior vena cava filter.

Description

technical field [0001] The invention relates to a medical operation instrument, in particular to an inferior vena cava filter which can effectively prevent pulmonary embolism and a preparation method thereof. Background technique [0002] Pulmonary embolism (PE) is a clinical and pathophysiological syndrome in which endogenous or exogenous emboli block the pulmonary artery or its branches and cause pulmonary circulation disturbance. The main and most common type is pulmonary thromboembolism (PTE), which also includes other types with pulmonary thromboembolism as the etiology, such as fat embolism, amniotic fluid embolism, air embolism, foreign body embolism, and tumor embolism. Pulmonary hemorrhage or necrosis after pulmonary embolism is called pulmonary infarction, and those originating from pulmonary artery in situ are called pulmonary thrombosis. [0003] The traditional inferior vena cava filter has the problems of inaccurate placement in the blood vessel, difficult rec...
