Background
"peripheral arterial disease" includes a variety of diseases that result in progressive stenosis or occlusion or aneurysm expansion of the aorta and its non-coronary artery branches, including carotid, upper, visceral and lower limb arterial branches. PAD is closely related with cardiovascular disease, its severity is the postcure index of cardiovascular risk, at present, still face very big challenge in PAD's thrombus clear away art, often need carry out the thrombus and clear away when patient's emergency call intervenes treatment, medical staff need hold accurate rescue time when carrying out the thrombus to patient and clear away the operation, the quick orientation pathological change position saves the operation time, quick high efficiency clears away the thrombus in vitro, when clearing away the thrombus of pathological change blood vessel, need guarantee to clear away the blood vessel of protective lesion department not damaged when the thrombus. In the current thrombus treatment scheme, two main treatment schemes are mainly adopted, one scheme is stent treatment, a stent is implanted at the position of a thrombus lesion generated in a blood vessel, the stent has the advantages of short treatment time and obvious clinical effect, and the defects of foreign body implantation, namely the stent implantation, long-term administration of an antithrombotic drug is required for the follow-up implantation, the stent cannot be taken out once implanted, and only bypass surgery can be performed if thrombus is coagulated at the stent again. The second method is to embed a thrombolysis catheter in the lesion where thrombus occurs and continuously release thrombolysis drug to the lesion by using drug spray holes on the thrombolysis catheter, and the method has the disadvantages of slow thrombolysis effect and long period. At present, mechanical thrombus removal is a great trend of thrombus removal, and mechanical thrombus removal requires that damage to a target blood vessel is reduced as much as possible while thrombus is broken, so that complications are reduced, and the use of a stent is reduced.
