Research On The Design Of Individualized Artificial Knee Joint Based On Function

The artificial knee joint technology is following behind the West Developed Nations' in our country at present, and the artificial knee joint markets are dominated by the import artificial knee joint products, these import products were usually designed according to European or American standard, so no matching things will be happened when don't finding a fitting size import products; in addition, there are some patients whose knee joints are abnormal don't find approving artificial knee joint in the markets. So it has important significance and practical value to develop the individualized artificial knee joint design and research.At present, most design of artificial knee joints are based on the comparability of knee joints geometrical figure, the geometrical figure is the starting point of design. Author brings forward a new idea and attempts to design artificial knee joint by this idea, taking the function as the starting point of design, designing the approving artificial knee joint by the mapping connection of function and structure, at last, validating the structure structural rationality by finite element analysis.The design of individualized artificial knee joint is a typical multi-subject field, it contains orthopaedics,biomedicine,biomechanics,image processing, surface reconstruction, CAD technology, and so on. Individualized artificial knee joint is the cooperative result of physic and engineering. In the paper, author develops the design of individualized artificial knee joint based on function, particular researches contain the theory foundation of artificial knee joint design,the design principle of individualized artificial knee joint based on function,the key technologies of individualized artificial knee joint design,the finite element analysis of individualized artificial knee joint.
