関節の運動軌跡を考慮した指用創外固定器の開発

抄録

We have developed a finger external fixator which considered motion trajectory of joint. The external fixator has design conditions of four as follows: (i) Material that is easy to penetrate X-ray. (ii) Conceived the link mechanism of the same movement as the finger joint. (iii)Small size that can be mounted on the dorsal surface of finger. The following results were obtained from the research:(i)The Material used CFRP is easy to penetrate X-ray. (ii)Movement of the rotation center when the finger bends is obtained, and a link mechanism similar to the function has been devised. (iii)Because it is small in comparison to the typical fixator, it's considered that the difficulty in daily life is reduced.
