摘要
背景:随着科技的不断进步,新技术和新方法的引入将为形状记忆合金在辅助和康复领域的应用带来更多的可能性和新的突破。目的:通过综述形状记忆合金在辅助器具和康复设备中的应用现状,讨论它们的主要方法、技术和结果,归纳总结并提出建议,希望形状记忆合金能够不断优化,为辅助和康复设备的发展带来更多新的变革。方法:通过计算机检索万方、Pub Med和Web of Science数据库,以“形状记忆合金,应用进展,正畸,矫形,假肢,康复,特性,植入,力学性能,镍钛记忆合金,驱动”为中文检索词,以“Shape memory alloys,Application,Orthodontics,Orthopedic,Prosthetics,Rehabilitation,Properties,Implant,Drive,Progress,Prostheses”为英文检索词,最终纳入91篇文献进行综述。结果与结论:(1)形状记忆合金具有耐腐蚀性、耐磨性、生物相容性、抗疲劳性和抗扭结性等特性,相比其他传统材料(不锈钢、钛合金、钴铬合金等)具有更低的弹性模量且无生物毒性,适合作为假体长期植入体内。由于其具有形状记忆效应和优异的力学性能,遂主要作为驱动元件或作为连接设备和人体的桥梁应用于假肢、矫形器和康复设备中。(2)使用形状记忆合金驱动元件能够减轻设备质量、消除噪声、容易操作、便于携带和更好地辅助关节运动等,比起使用气动、液压和电气驱动方法的设备优势明显。(3)另外形状记忆合金在变形时能够产生恒久、稳定的应力,相比不锈钢、钛合金和铝合金矫形器具有更高的材料回收率且不用频繁更换调整,所以在矫治畸形方面更具实用价值。(4)目前形状记忆合金在矫形器中应用最多,在镫骨假体中的临床应用效果最好。而由于技术及成本等的限制,形状记忆合金在假肢和康复设备中的应用较少,且缺乏对应用效果的大样本研究。(5)虽然形状记忆合金在辅助和康复领域得到了一定的发展,但�
BACKGROUND:With the continuous progress of science and technology,the introduction of new technologies and methods will bring more possibilities and new breakthroughs for the application of shape memory alloys in the fields of assistive and rehabilitation.OBJECTIVE:To review the application status of shape memory alloys in assistive and rehabilitation equipment,discuss their main methods,techniques and results,summarize and put forward suggestions,hoping that shape memory alloys can be continuously optimized and bring more new changes for the development of assistive and rehabilitation equipment.METHODS:WanFang,PubMed,and Web of Science databases were searched by computer.“Shape memory alloys,application progress,orthodontics,orthopedic,prosthesis,rehabilitation,properties,implantation,mechanical properties,nickel-titanium memory alloys,actuation”were used as Chinese search terms.“Shape memory alloys,application,orthodontics,orthopedic,prosthetics,rehabilitation,properties,implant,drive,progress,prostheses”were used as English search terms.Finally,91 articles were included for review.RESULTS AND CONCLUSION:(1)Shape memory alloy has the characteristics of corrosion resistance,wear resistance,biocompatibility,fatigue resistance,kink resistance and other properties.Compared with other traditional materials(stainless steel,titanium alloy,cobalt-chromium alloy,etc.),shape memory alloy has lower elastic modulus and no biological toxicity,which is suitable for long-term implantation as an implant prosthesis.Due to its shape memory effect and excellent mechanical properties,it is mainly used as a driving element or as a bridge connecting the device and the human body in artificial limbs,orthoses and rehabilitation equipment.(2)The use of shape memory alloy drive elements can reduce the weight of the device,eliminate noise,easy to operate,easy to carry,better assist joint movement;compared with the use of pneumatic,hydraulic,and electrical drive methods of the device,it has obvious advantages.(3)In addition,shape
