Abstract

The invention discloses a multifunctional thrombolysis and thrombus breaking large-caliber suction catheter, which comprises a thrombus suction connector, a thrombolysis medicine connector and a catheter, wherein the thrombus suction connector is provided with the thrombolysis medicine connector; the right end of the thrombus suction connector is provided with the catheter; the inner cavity of the catheter is a suction inner cavity; the catheter is provided with an X-ray-proof marker point A and an X-ray-proof marker point B; in addition, positions which are near the front position and the back position of the X-ray-proof marker point A, are independently provided with a first near-end ejection hole and a second near-end ejection hole; a position, which is near the left side of the top end of the X-ray-proof marker point B, is provided with a first far-end ejection hole; a position, which is near the left side of the bottom end of the X-ray-proof marker point B, is provided with a second far-end ejection hole; and the first near-end ejection hole communicates with a first near-end ejection hole medicine conveying channel. The multifunctional thrombolysis and thrombus breaking large-caliber suction catheter can efficiently and quickly remove thrombus, quickly recovers unobstruction of blood vessels, also can reduce a thrombolysis bleeding risk, reduces postoperative complications and improves a clinical effect.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a multifunctional thrombus-dissolving large-diameter suction catheter. Background technique [0002] Both venous thromboembolism (VTE) and arterial thromboembolic disease are common and frequently-occurring diseases that seriously endanger human health. Forgarty first applied balloon thrombectomy in 1963, and the mortality rate was 10%-25%. The recurrence rate of VTE during 10 years after treatment is about 20%-30%. Among them, VTE includes deep vein thrombosis (deep vein thrombosis, DVT) and pulmonary thromboembolism (pulmonary thromboembolism, PTE). The incidence of DVT is about 88 / 100,000 person-years to 112 / 100,000 person-years. In 1854, Virchow first discovered arterial thromboembolic disease and named it Embolus. The incidence of arterial thrombosis is about 6%, and the incidence of arterial embolism is about 1%. Severe arterial thromboembolic disease can lead to a...
