Abstract
The invention discloses a thrombus suction device for vascular surgery, which belongs to the technical field of medical equipment and solves the problem that thrombus residues are caused by the fact that a large amount of thrombus fragments are generated in the traditional technology and can not be absorbed by all the fragments in the suction process.

Technical Field
The invention belongs to the technical field of medical equipment, and particularly relates to a thrombus suction device for vascular surgery.
Background
Thrombi are small patches of blood flow that form on the surface of a denuded or repaired site within a blood vessel of the cardiovascular system. In the variable fluid-dependent type, the thrombus is composed of insoluble fibrin, deposited platelets, accumulated white blood cells and entrapped red blood cells. Thrombosis is a multifactorial process of change that is influenced by the interaction of a set of genetic and environmental factors. The clinical common thrombus patients are mainly characterized by familial inheritance, recurrent attacks, symptom severity, abnormality of thrombus formation sites and younger onset time. Objective evidence is needed to suspect arterial or venous thrombosis or thromboembolism. Angiography is the reference standard for diagnosis, but superficial blood vessels and the heart can also be examined by well-understood ultrasound tests.
In patients with venous imaging demonstrating spontaneous deep vein thrombosis, genetic predisposition is present in 25% to 50% of cases. In the presence of a deficiency in the innate anti-coagulation mechanism (e.g., factor V activated protein C, homocysteinemia, protein C deficiency, protein S deficiency, antithrombin deficiency, fibrinolytic insufficiency) in a subject, venous thromboembolism may be sufficient in combination with a thrombotic stimulus (e.g., surgery, pregnancy, administration of contraceptives, antiphospholipid antibodies). Early patients with multiple sites of thrombosis had a significantly increased frequency and severity of episodes compared to single thrombosis.
Antithrombotic therapy uses thrombolytic drugs, antiplatelet drugs and anticoagulants. In formulating anti-thrombotic treatment strategies, attention is first paid to thrombolytic drug therapy, which removes a formed thrombus, and anti-thrombotic therapy is diversified depending on whether the affected site is the venous or arterial circulatory system, the degree and site of vascular involvement, the extension of thrombosis, the risk of embolism or recurrence, and the relative advantages and disadvantages of anti-thrombotic therapy and hemorrhage.
The artificial mechanical method for restoring the unobstructed blood vessel comprises balloon catheter operation and surgical embolectomy; the indications and complications are associated with antithrombotic treatment of specific disease species (e.g. myocardial infarction, venous thrombosis, pulmonary infarction, cerebrovascular accident, prosthetic heart valves, arterial embolism).
