Multifunctional thrombus treatment device and use method thereof

Abstract

The invention provides a multifunctional thrombus treatment device and a using method thereof.The multifunctional thrombus treatment device comprises a guide wire, a variable-diameter thrombus extraction support, a fixing catheter and a recycling catheter, the density of a far-end net part of the variable-diameter thrombus extraction support is large, so that escaped small thrombus can be caught, and the thrombus can be recycled. A sliding opening is formed in the far end of the variable-diameter thrombus extraction support and sleeves the guide wire, the near end of the variable-diameter thrombus extraction support is connected with the far end of the fixed catheter, the diameter of the variable-diameter thrombus extraction support can be adjusted by adjusting the positions of the guide wire and the fixed catheter, and thrombus of different sizes in a blood vessel can be fully captured; the recycling catheter is arranged on the outer wall of the fixed catheter in a sleeving mode and can be used for containing the variable-diameter thrombus taking support, thrombus can be captured and netted to the maximum extent by repeatedly changing the diameter of the variable-diameter thrombus taking support, and large thrombus difficult to capture can be captured after being dissolved and reduced in advance through the fixed catheter and the recycling catheter. And various treatment methods such as thrombolysis, thrombus extraction and net thrombus can be completed at the same time.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a multifunctional thrombus treatment device capable of simultaneously realizing thrombolysis and thrombus removal and a method for using the same. Background technique [0002] Abnormal vascular channels cause blood to flow abnormally in the blood vessels. This abnormal flow of blood flow will cause a series of adverse consequences such as tissue hypoxia, abnormal intravascular pressure, increased cardiac load, and even heart failure. Therefore, abnormal channels generally need to pass through catheters. Interventional techniques restore or reestablish blood flow within vessels. [0003] When blood vessels are narrowed or blocked, it can also cause multiple adverse effects, such as turbulent blood flow, slowing down the flow rate, which can lead to the formation of blood clots, which restrict the blood supply to the downstream areas of the vasculature. When the blood clot is loc...
