Background
Thrombus is a small block of blood flow formed on the surface of the inside surface of a cardiovascular system vessel where it is exfoliated or repaired. In the variable fluid dependency (variable flow dependent patterns)), the thrombus consists of insoluble fibrin, deposited platelets, accumulated white blood cells and entrapped red blood cells. If thrombus forms a blockage in the blood vessel of a human body, the blood flow is interrupted, myocardial infarction can occur when the thrombus is blocked in coronary arteries, cerebral infarction can occur when the thrombus is blocked in cerebral arteries, pulmonary embolism can occur when the thrombus is blocked in pulmonary arteries, limb infarction can occur when the thrombus is blocked in limb artery and vein, and the coronary artery are serious diseases and even endanger lives.
For thrombus treatment, the traditional treatment methods mainly comprise a vascular cut thrombolysis operation, a vascular intima stripping operation, a catheter thrombolysis operation, a cut thrombolysis operation and an intima stripping operation, the vascular cut thrombolysis operation and the intima stripping operation need to be dissected and separated, and the vascular cut thrombolysis operation is carried out after the cut, so that the operation wound is very large. With the development of the endoluminal interventional technique and the innovation of materials, the open surgical mode is gradually replaced by minimally invasive interventional endoluminal treatment, including catheter thrombolysis, thrombus aspiration and the like.
The thrombus aspiration is commonly carried out by adopting a thin-wall large-cavity catheter design and adopting a negative pressure suction pump; for subacute, coanda or lump-shaped thrombus, the suction difficulty, even the blockage of the catheter head end and the collapse of the catheter can be caused by the adhesiveness and the difficult separation of the thrombus due to the simple suction of the catheter.

Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1 to 3, in an embodiment of the present utility model, an anti-thrombus-blockage separator includes a guide wire 1 and a thrombus aspirator, wherein the thrombus aspirator is sleeved on the guide wire 1, and specifically, the thrombus aspirator includes a suction sheath tube 3 and a tailstock 4 sleeved on the guide wire 1, one end of the suction sheath tube 3 is fixedly connected with the tailstock 4, and the tailstock 4 is connected with a joint 5 through a hose, one end of the guide wire 1 is provided with a handle 2, an outer wall at the other end of the guide wire 1 is provided with a thrombus separator, the thrombus separator includes at least one expandable mesh sphere 7, the mesh sphere 7 is in an ellipsoidal shape, one end of the mesh sphere 7 is fixed on the guide wire 1, the other end of the mesh sphere 7 is slidably connected with the guide wire 1, and the thrombus separator further includes a solid metal body 8 sleeved on the guide wire 1.
