技术领域technical field
本发明属于骨科器械技术领域，具体涉及一种结构合理、配装简便的耐用型仿生合金指关节替换件。The invention belongs to the technical field of orthopedic instruments, in particular to a durable bionic alloy finger joint replacement part with reasonable structure and simple assembly.
背景技术Background technique
人们在日常生产与生活过程，难免会受到意外造成手掌及手指骨折伤害，或者因为风湿等疾病导致手掌指关节活动受限，甚至失去正常的生理功能。常规技术手段就是人工假体进行关节替换，但是，用现有技术的可替换假体进行修复，不仅初始稳定性不好，而且长期骨生长也不好，长期稳定性也不好。尤其全关节替换之情形，用现有技术人工关节则前述弊端更加凸显出来。究其原因在于假体关节面的适形性差，结合面的连接结构不合理，导致上述不良效果的发生。本发明人以为针对现有技术之不足，开发更符合人体生物力学结构，机械配合性好，成本低廉，适形性好且耐固接的仿生指关节替换部件，代替现有技术之假体，是克服现有技术缺陷的有效方式。In the process of daily production and life, people will inevitably suffer from accidental fractures of the palm and fingers, or because of diseases such as rheumatism, the activities of the palm and finger joints are limited, or even lose their normal physiological functions. The conventional technical means is to replace the joint with an artificial prosthesis. However, using the replaceable prosthesis in the prior art for repair not only has poor initial stability, but also has poor long-term bone growth and long-term stability. Especially in the case of full joint replacement, the aforementioned drawbacks are more prominent when using the existing artificial joint. The reason is that the conformability of the articular surface of the prosthesis is poor, and the connection structure of the joint surface is unreasonable, which leads to the occurrence of the above-mentioned adverse effects. The inventors of the present invention believe that aiming at the shortcomings of the prior art, to develop a bionic finger joint replacement part that is more in line with the human body's biomechanical structure, has good mechanical compatibility, low cost, good conformability and resistance to fixation, instead of the prosthesis in the prior art, It is an effective way to overcome the defects of the prior art.
