研究目的:

第一阶段目标(动物实验): 1) 验证假体在大型动物体内的生物相容性(通过组织学分析)。 2) 评估假体的短期稳定性与固定强度。 3) 测试智能传感系统在活体环境中的功能可靠性。 第二阶段目标(人体研究): 本研究旨在首次于人体中评估一款融合了智能晶格结构、3D曲面打印与压电传感技术的个性化仿生距骨假体的安全性、可行性与初步疗效,为终末期距骨疾病治疗难题提供一种全新的、智能化的治疗方案,并为后续大规模临床研究奠定基础。  

Objectives of Study:

First-stage goals (animal experiments) :1)Verify the biocompatibility of the prosthesis in large animals (through histological analysis).2) Evaluate the short-term stability and fixation strength of the prosthesis.3) Test the functional reliability of the intelligent sensing system in a living environment.The second-stage goal (human research) :This study aims to evaluate for the first time in humans the safety, feasibility and preliminary efficacy of a personalized bionic talus prosthesis that integrates intelligent lattice structure, 3D surface printing and piezoelectric sensing technology, providing a brand-new and intelligent treatment solution for the treatment of end-stage talus diseases and laying the foundation for subsequent large-scale clinical research.
