Abstract

The invention relates to the technical field of medical instruments, and discloses a thrombus removing device. The device comprises a thrombectomy stent, an inner tube and a pushing tube, the inner tube penetrates through the thrombectomy stent and the pushing tube, the far end of the inner tube is connected with the far end of the thrombectomy stent, and the inner tube can move relative to the pushing tube in the axial direction; the near end of the thrombectomy stent is connected with the far end of the pushing tube; the thrombectomy stent is of an expandable and retractable stent structure and comprises a collecting part and a cutting part; the far end of the collecting part is smoothly connected with the near end of the cutting part, the collecting part is of a tubular structure with the closed far end, meshes are formed in the peripheral wall of the cutting part, and an opening is formed in the near end of the cutting part. According to the embodiment of the invention, the thrombus extraction efficiency and thrombectomy effect can be improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a thrombus removal device. Background technique [0002] Vascular disease has become the number one fatal disease in my country, and vascular embolism has become the main pathogenic factor in vascular disease. In particular, patients with ischemic stroke, pulmonary embolism, and lower extremity venous embolism have a total of more than 5 million new cases each year. [0003] The use of thrombectomy device for interventional thrombectomy has many advantages such as less trauma, short postoperative recovery time, fewer complications after treatment, and good surgical effect, and is more acceptable to patients. Existing interventional thrombectomy programs mainly include catheter-based thrombolysis and thrombus aspiration. Thrombolytic therapy with catheters has the risk of causing cerebral hemorrhage or systemic hemorrhage, and thrombolysis with catheters for a long t...
