Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a sectional type serrated thrombus breaking balloon catheter.
Background
Venous Thromboembolism (VTE) includes Deep Venous Thrombosis (DVT) and Pulmonary Thromboembolism (PTE), both of which are manifestations of the same disease at different stages of pathogenesis and in different tissues and organs. Deep venous thrombosis of the lower limb refers to a clinical syndrome that blood in a deep venous system is coagulated to form thrombus and cause corresponding blood vessel blood backflow disorder due to various reasons. Venous stasis, venous wall damage and hypercoagulable state of blood are currently considered as the three major causes of deep vein thrombosis. When the vein thrombus of the lower limb falls off, emboli can enter pulmonary artery along the blood flow, and can cause fatal pulmonary artery embolism to seriously harm the life of a patient. In the United states, VTE incidence is about 1.17/1000 year, and VTE is newly issued about 35 ten thousand cases each year; the incidence of VTE in China is also gradually increased, and the VTE is still the third vascular disease causing death at present.
At present, the treatment scheme of the deep vein thrombosis of the lower limb mainly comprises medicine conservation treatment and operation treatment. Among them, anticoagulant therapy is the most basic method of DVT, and is effective in inhibiting thrombus propagation, and accelerating thrombolysis and revascularization. The thrombolytic therapy comprises systemic thrombolysis and catheter thrombolysis, the systemic thrombolysis is a thrombolytic drug injected through peripheral veins, and the thrombolytic efficiency is low and the bleeding risk is high; the catheter thrombolysis is to inject thrombolytic medicine directly into thrombus with side hole, and this can reduce the dose of thrombolytic medicine and reduce hemorrhage risk, but it is still difficult to eliminate thrombus completely. The vein is needed to be cut in the process of surgical thrombus removal, and then a Fogarty catheter is used for removing the thrombus in the vein; but often with complications such as damage to the venous valve and the vessel wall, bleeding, etc. The drug-mechanical combined thrombectomy is to crush and suck thrombus out of the body by utilizing the negative pressure suction principle, and simultaneously, the local thrombolytic drug injection is combined to accelerate thrombolysis and reduce thrombolytic drug dosage; however, the operation mode has high treatment cost, and most patients are difficult to pay high operation cost, so that the further application of the operation mode is limited. Therefore, a medical instrument with good clinical effect, rapid thrombus removal, high quality and low price is urgently needed in clinic, and a split type balloon thrombus crushing catheter is invented, so that the thrombus is expected to be removed rapidly and thoroughly, the venous blood flow is recovered, and the economic burden of a patient is reduced.
