Abstract

The invention discloses a local circulation type thrombus removing device. The local circulation type thrombus removing device mainly comprises an impeller assembly used for smashing the thrombus, a head end protective pipe, an inner pipe, an outer pipe, a first Y-shaped valve and a second Y-shaped valve. A first annular cavity is formed between the inner pipe and the impeller assembly, a second annular cavity is formed between the outer pipe and the inner pipe, the first Y-shaped valve is provided with a fluid infusion connector used for being connected with a fluid infusion pump, the fluid infusion connector is communicated with the second annular cavity, the second Y-shaped valve is provided with a thrombus removing connector used for being connected with a thrombus sucking pump, and the thrombus removing connector is communicated with the first annular cavity. The local circulation type thrombus removing device can improve the thrombus removing rate, prevent the venous intima from being injured, completely discharge the thrombus broken grains out of the body and prevent normal blood from excessive loss. The local circulation type thrombus removing device is especially suitable for removing the human body deep femoral vein thrombus by the adoption of the percutaneous minimally invasive surgery.

Description

technical field

[0001] The invention relates to a medical device, in particular to a partial circulation thrombus remover. Background technique

[0002] Due to changes in dietary structure and other reasons, the incidence of thrombosis in people is on the rise, especially the number of cases of deep vein thrombosis in the lower extremities is increasing. Thrombus deposition in veins can cause blood flow disturbance and stasis, resulting in thrombophlebitis within the veins. For patients with chronic iliofemoral vein thrombosis, venous thrombosis can lead to long-term swelling of the lower limbs, varicose veins, and ulceration. In addition, after the venous thrombus falls off, it may also transfer to other parts and organs of the body, resulting in serious complications. For example, a thrombus in a vein travels through the vein and deposits in the lung, causing a pulmonary embolism that can lead to death. Therapeutic methods for thrombosis include: 1. Internal medicine tr...
