Abstract

Osseointegration prosthesis is a directly implanted fixation in the bone for limb amputees. It has been used as an excellent alternative for amputees experiencing difficulties from the use of a traditional socket type prosthesis. A novel implant used for implanted prosthetics is designed and it depended on polymer as a primary material to increase bone osseointegration. As an alternative to the metallic material on the interface with the bone. The design consists of several parts and relies on thread to increase installation. This research aims to overcome the problems of loss implantation by using new designs for fixations. Evaluated this design by FEA (Finite element analysis) in different load cases to obtain the distribution of stress and force reaction when the implant displacement was applied. The polymeric part was designed in two shapes, each shape relies on a different size of threaded to verify the change of fixation with the threaded. As for the metal part, two cases were used, the first case, stainless steel 316L, and the second case titanium metal to reach the best stress distribution in this design.

基于有限元分析的新型假体种植接头评价

骨整合假体是一种为截肢者直接植入骨内的固定装置。对于因使用传统的承窝型假体而遇到困难的截肢者来说，它已被用作一种极好的替代品。设计了一种用于植入假体的新型植入物，该植入物依靠聚合物作为主要材料来增加骨-骨结合。作为与骨骼界面上的金属材料的替代方案。该设计由几个部分组成，并依靠螺纹来增加安装。本研究旨在通过使用新的固定设计来克服丢失植入的问题。通过FEA（有限元分析）在不同载荷情况下对该设计进行评估，以获得植入物位移时的应力和反作用力分布。聚合物部件设计为两种形状，每种形状都取决于不同尺寸的螺纹，以验证螺纹固定的变化。对于金属部件，使用了两种情况，第一种情况是316L不锈钢，第二种情况是钛金属，以在本设计中达到最佳应力分布。
