Enhancing Biocompatibility and Performance of Multi-directionally Expanding Materials for Dental Applications: Design and Analysis
摘要
Stents are vital in maintaining artery and duct patency by preventing blockages. However, modern stent types have complications, including thrombosis and bleeding. Our goal is to create a 3D-printed, biocompatible, self-expanding polymer stent to address these issues. Auxetic stents, characterized by their unique mechanical properties, hold promise in addressing these complications. Achieving the Auxetic structure involves a comprehensive exploration of various unit cell designs. In our research, we have meticulously crafted computer-aided design (CAD) models of stents, focusing on the arrowhead unit cell design, utilizing solid works software. Subsequently, we conducted a thorough analysis of the stent-ballooning system using Ansys software, with the stent material modeled as structural steel. This analysis lays the foundation for our upcoming simulations, where we aim to investigate the use of polymer materials, such as PLA. Ultimately, our goal is to discover and refine an optimal stent design, bolstering confidence in the utilization of polymer materials like PLA (polylactic acid) for stent placement and thereby enhancing patient outcomes.
