人工髋、膝关节磨损测试标准及模拟试验机研究进展

Review of the Artificial Hip and Knee Wear Testing Standards and Simulation Testing Machines

  • 摘要: 髋膝关节植入物假体在体内发生摩擦磨损进而造成骨溶解、无菌松动是导致其失效的重要原因之一. 人工髋膝关节磨损试验是对假体材料、设计和加工进行评价的重要形式. 天然髋膝关节承受的运动和载荷十分复杂,研究天然关节在各种行为下的受力和运动范围,并利用专门的髋膝关节模拟器来进行试验和评价,有助于人工关节的设计和耐磨关节材料的发展. 本文中整理了天然髋膝关节的运动范围及载荷,对比了人工髋膝关节假体磨损的国内外标准,总结了主流髋膝关节模拟试验机的结构及主要技术参数,为我国关节行业的研究者提供参考.

     

    Abstract: Hip and Knee joint prosthesis suffers friction and wear in the body, which leads to bone dissolution and aseptic loosening. Hip and Knee joint implants wear test is a major way to evaluate the materials, design and processing of prosthesis. The movement and load of the synovial hip and knee joints are very complicated, so studying the force and range of motion of synovial joints under various behaviors, as well as using the special hip/knee joint simulator for testing and evaluation, is helpful for the design and development of artificial joints and wear-resistant materials. This paper sorts the movement range and load of synovial hip and knee joints, compares the domestic and international wear standards of artificial hip and knee prosthesis, summarizes the structure and main technical parameters of the mainstream hip and knee joint simulator, and provides a reference to studies in the artificial joint industry in China.
