Inferior vena cava thrombus filter convenient for thrombus ablation

Abstract

The invention discloses an inferior vena cava thrombus filter convenient for thrombus ablation. The inferior vena cava thrombus filter comprises an outer sleeve, one end of the outer sleeve is provided with a console, the other end of the outer sleeve is provided with a filtering assembly used for filtering thrombus, and the outer sleeve is internally provided with a driving catheter used for driving the filtering assembly to be unfolded and folded. A movable groove is formed in the outer sleeve, the driving guide pipe is slidably connected in the movable groove in a sleeved mode, the driving guide pipe is driven by the telescopic driving unit to achieve axial movement in the outer sleeve, and a medicine spraying assembly used for spraying medicine is arranged at an opening in the front end of the filtering assembly. The inferior vena cava thrombus filter has the beneficial effects that 1, in the vein, blood is filtered through the filtering assembly, so that thrombus in the blood is blocked; 2, the medicine spraying heads which are distributed circumferentially are arranged at the front end of the filtering assembly, and thrombus in the blood can be sprayed and melted.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to an inferior vena cava thrombus filter which facilitates thrombus ablation. Background technique [0002] Inferior vena cava thrombosis is an acute non-suppurative inflammation of the vein. The most common clinical manifestation is swelling and pain in both lower extremities, especially after standing upright and walking. Because the inferior vena cava thrombus is not firm in the early stage, it is easy to fall off, leading to a higher probability of pulmonary embolism. Therefore, some patients may experience chest tightness, shortness of breath, chest pain, bloody cough, and even dyspnea and coma. A life-threatening situation arises. For the treatment of inferior vena cava thrombosis, interventional thrombolysis or thrombus suction can be used to remove the thrombus in the blood.

Problems solved by technology

[0004] 1. When filtering, the thrombus captured by the filter umbrella is easy to attach to the mesh surface, thereby blocking the blood circulation channel, resulting in poor blood circulation;
