摘要

下肢假肢可以代替身体缺失的部分，提高病人的生活质量。假肢的个性化设计和制造对佩戴者尤其有益。3D打印技术可用于用回收聚酰胺粉末(PA2200)制作假体插座，但这些打印材料的机械性能尚未得到详细研究。进行了拉伸和弯曲测试，获得的结果在这些材料之间没有统计学上的显着差异。不合适的假肢会影响步态的生物力学。使用“Qualisys”、“AMTI”力板和“Zebris”系统对佩戴义肢的人进行姿势和步态分析，结果显示义肢与健康腿之间存在差异。

Transfemoral Prostheses: Importance of Proper Fitting and Materials for Socket 3D-Printing

Lower limb prostheses can replace missing parts of the body and improve a patient's quality of life. The individual design and manufacture of a prosthesis is particularly beneficial for the wearer. The 3D printing technique can be used to make prosthesis sockets from recycled polyamide powder (PA2200), but the mechanical properties of these printed materials have not been studied in detail. Tensile and bending tests were performed, and the results obtained did not show statistically significant differences between these materials. An improperly fitted prosthesis affects the biomechanics of gait. Posture and gait analysis of a person wearing a prosthesis was performed using the “Qualisys”, "AMTI" force plates, and “Zebris” systems, and the results showed differences between the prosthetic and the healthy leg.
