研究目的:

为了克服传统人工血管的上述局限,研发一款能够实现“即时穿刺”(early cannulation)并促进“快速内皮化”(rapid endothelialization)的新一代仿生人工血管,已成为血管外科和生物材料领域的研究热点和迫切需求。本研究项目所开发的新型中、小管径人工血管(以下简称“本产品”),正是基于这一临床需求,采用前沿的“静电纺丝”与“增材制造(3D打印)”相结合的技术,旨在通过多层次、多功能的结构设计,从根本上解决血栓形成、内膜增生和等待期过长三大痛点,为血液透析患者提供更优越的血管通路解决方案。本产品内径设计为4-6 mm,长度40 cm,精准定位于血液透析AVG应用最常见的规格。该设计旨在实现快速内皮化、降低血栓与狭窄风险,并缩短透析前等待时间,为慢性肾脏病患者提供更安全、高效的血管通路解决方案。  

Objectives of Study:

To overcome the aforementioned limitations of conventional vascular grafts, the development of a new-generation biomimetic artificial blood vessel capable of "early cannulation" and promoting "rapid endothelialization" has become a research hotspot and urgent demand in the fields of vascular surgery and biomaterials. The novel small-to-medium diameter vascular graft developed in this study (hereinafter referred to as "this product") is precisely designed to address this clinical need. By integrating cutting-edge "electrospinning" with "additive manufacturing (3D printing)" technologies, this product aims to fundamentally resolve three critical pain points—thrombosis formation, intimal hyperplasia, and prolonged waiting periods—through hierarchical, multifunctional structural design, thereby providing a superior vascular access solution for hemodialysis patients. This product features an internal diameter of 4–6 mm and a length of 40 cm, precisely targeting the most commonly used specifications for hemodialysis AVG applications. This design aims to achieve rapid endothelialization, reduce the risks of thrombosis and stenosis, and shorten the pre-dialysis waiting time, offering a safer and more efficient vascular access solution for patients with chronic kidney disease.
