FIELD
The invention relates to the technical field of medical instruments, in particular to a water flow replacement thrombus suction device.
Background
Peripheral Arterial Disease (PAD) includes a series of non-coronary systemic syndromes caused by structural and functional changes in the arteries supplying the brain, internal organs and limbs, i.e., stenosis, occlusion or neoplastic-like expansion of the aorta and its branches other than the coronary arteries. Multiple pathophysiological mechanisms can lead to stenosis or neoplasia of these non-coronary blood circulation, but atherosclerosis remains a major cause of involvement of the aorta and branch arteries. With the development of the intracavity treatment technology and interventional instrument technology, Percutaneous Transluminal Angioplasty (PTA) has become an important treatment means for ischemic diseases of lower limbs, however, the long-term restenosis rate of PTA reaches about 40%, which becomes a development bottleneck of the technology, and is unavoidable and unresolved; in recent years, thrombus volume reduction technology (TDT) is proposed in the development of peripheral vascular therapy technology, and TDT is an important surgical auxiliary treatment means. Can effectively save medical cost, improve cure rate and reduce pain, disability rate and fatality rate of patients. Mechanical thrombus removal pmt (transient thrombus) is the most advanced and effective peripheral arterial and venous thrombus volume reduction technology at present, however, when a thrombus removal operation is performed, a diseased blood vessel can be injured, so that mechanical thrombus removal is required to achieve the aims of breaking thrombus and reducing thrombus flow as far as possible, thereby threatening life and reducing complications.
