Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a multifunctional venous thrombus taking device.
Background
Venous thrombosis blocking the venous vessels is a common venous disease that can occur anywhere in the venous system, with the inferior limb veins being most common and the secondary major inferior vena cava. The disease has great harm to patients, the thrombus falls off to pulmonary artery to cause fatal pulmonary embolism, and the long-term retention of the thrombus in the deep vein of the lower limb can cause post-thrombotic syndrome. Clinical evidence suggests that treatment as early as possible and thorough definition of thrombi is a central tool in the treatment of venous thrombi.
In the prior art, methods for treating venous thrombosis include: phlebotomy embolectomy, intravenous catheterization, thrombolysis, and venous thrombectomy. The vein incision embolectomy can remove most of thrombus in the vein cavity, and is a more thorough treatment method for treating vein thrombus. However, after the vein is cut and the thrombus is taken, postoperative symptoms such as incision infection, lymphatic leakage, delayed wound healing and the like are easy to occur, and in addition, the operation of the inferior vena cava thrombus shell is difficult and has large wound; in the vein catheterization thrombosis, thrombolytic medicines such as urokinase and the like directly act on thrombus through a thrombolytic catheter. The operation can dissolve thrombus partially, but a large amount of thrombus remains after the operation, and the incidence rate of post-thrombus syndrome is still high. The thrombus aspiration adopts devices such as a catheter, a sheath tube and the like, and the thrombus is extracted out of the body by adopting a negative pressure suction mode. The technical scheme has the advantages of thorough thrombus removal in the phlebotomy thrombus removal operation and minimally invasive characteristic of the catheterization thrombolysis operation, so that the thrombus aspiration is an ideal operation method for treating venous thrombus, and residual thrombus can be hurt to a human body because the thrombus cannot be completely removed.
