形狀記憶合金應用於指關節動態副木之研究
A STUDY ON THE APPLICATION OF SHAPE MEMORY ALLOY ON DYNAMIC SPLINT IN FINGER JOINT
摘要
本研究針對手指損傷術後復健所需，提出一種新型『全指關節動態副木』。主 要是利用形狀記憶合金(Shape Memory Alloy , SMA)來提供手指復建所需的助力或 阻力，本文將針對動態副木的結構設計及控制方法進行研究。 本研究採用Ti50N45Cu5銅系SMA線，將4支ψ1.0mm的SMA為一捆穿設於矽膠套 管中，再將六支矽膠套管沿手指方向在指腹或指背上平行排列，並將其設計成可順 應指關節運動的撓性指套結構。當患者進行復健時，指套上的SMA通以適當的電流 即可提供復健所需的阻力或助力。 研究中開發了兩種動態副木：(1)固定型動態副木在設計上賦予多種可調整機 制，可廣泛的活用於各種大小不同的手指，並針對全指關節進行復健，適合於醫療 診所使用，主要以PC為控制核心。(2)可攜式型動態副木則針對家庭復健方便攜帶而 設計，以單晶片作為控制核心。 以上二者均具備SMA溫度迴授控制功能，使副木可在設定的安全溫度下操作， 此副木的輸出力量可提供最大22N的復健阻力或助力。

A new type of “Full finger joint dynamic splint” was proposed in this paper. The SMA was used to construct the full finger joint dynamic splint to offer resistance and auxiliary for rehabilitation in need. The structure design and the control method for dynamic splint were investigated in this study. Four SMA wire with Ti50Ni45Cu5 of ψ1.0mm were bound in one and put it into a silica gel tube. Six pieces of such a silica gel tube can be set along the up or down side of fingers. When patients were going to rehabilitate, the suitable electric current was supplied to the SMA and then it can offer resistance and auxiliary in need. Two kinds of dynamic splint were developed here: The first one offers many kinds of operation functions. It can be used not only for any fingers size but also whole finger in hand. It also fit for using on medical treatment and was controlled by a PC. The second one was designed for personal convenient to use at home and was controlled by single chip microcontroller. Both of them have SMA temperature feedback control capability, and can be operated under a setting temperature safely. The output strength of splint can offer maximum 22N resistance or auxiliary in rehabilitation.
