▎ 摘　　要

NOVELTY - The bracket has a bearing pipe body whose inflow end is communicated with a distal end of a graphene. An outflow end of the bearing pipe body is communicated with a near-end flow guide of the graphene, when a graphene near-end flow guide ports are coaxially distributed, when maximum pipe diameter of the graphene far-end flow guide hole is measured for about 1.5-2.5 times of the pipe diameter of the bearing pipe body. A graphene proximal end flow guide opening forms a working group, where the graphene proximal end flow guide opening of a previous working group and the graphene near-end flow guide port of a subsequent primary working group are mutually connected and coaxially distributed. USE - Interventional bracket for preventing large amount of bleeding from cardiology department. ADVANTAGE - The bracket has better vascular expansion performance, small surface area, high supporting force, better biocompatibility, high bearing capacity, high covering capacity, better tracer performance and better hydrodynamic performance, and effectively improves blood flow property of a blood vessel, and effectively reduces risk of thrombus formation, and greatly improves convenience and precision of detection and positioning of the bracket after heart bridging operation. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of an interventional bracket.
