Problems solved by technology

However, at present, medical treatment commonly used in clinical practice cannot quickly remove thrombus and relieve blockage. The volume expansion, anticoagulant, and thrombolytic therapy adopted not only have poor efficacy, but also have a limited treatment time window, and are even prone to serious consequences of tissue hemorrhage.

Abstract

The invention provides a thrombectomy device. The thrombectomy device includes a catheter and a cutting assembly. The cutting assembly includes a knife net, a knife head, a transmission shaft and a power source. The knife net is fixed on the end face of the catheter. The net is provided with a hollow part, the cutter head is connected to one end of the transmission shaft, at least a part of the cutter head and the transmission shaft are located in the conduit, and the power source drives the cutter through the transmission shaft The head rotates in the guide pipe; the cutter head is a semi-circular-like body, and its surface close to the knife net is the first surface, and the first edge and the third edge are respectively connected to the second edge and the fourth edge. two ends; the cutter head and the cutter net form a cutting structure, the cutting structure includes a first cutting edge and a second cutting edge, the first edge and the third cutting edge constitute the first cutting edge, and the second cutting edge located on the knife net. The thrombectomy device provided by the invention has the advantages of good thrombectomy effect and the like.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a thrombectomy device. Background technique [0002] A thrombus is a small block formed by blood flow on the surface of the inner surface of the blood vessel in the cardiovascular system, which is peeled off or repaired. It is composed of insoluble fibrin, deposited platelets, accumulated white blood cells and trapped red blood cells. Thrombosis causes a decrease in blood flow or interruption of blood supply to the local brain, and ischemia and hypoxia of cerebral tissue lead to softening and necrosis, resulting in focal neurological symptoms, resulting in atherosclerotic cerebral or myocardial infarction. When a thrombus occurs, the activity of the nerve center and important physiological functions are threatened due to the ischemia of the local tissue due to vascular occlusion. If the blockage in the blood vessel cannot be removed in time to make the blood flow unobstructed, the ...
