Description

膝関節用装具Knee joint orthosis

　本発明は、膝関節に装着して歩行補助を行える膝関節用装具に関する。 The present invention relates to a knee joint orthosis that can be attached to a knee joint to assist walking.

　膝関節用装具は、副木の原理を応用して、障害部である膝関節を副木に固定し、膝の変形を矯正し加えて障害部位を保護するものであると考えられてきた。膝装具のカフは患者の障害レベルに応じて、カフ数を調整して適用するのが一般的である。従来の複数カフ構造の装具は、１本カフ装具よりも支持力・矯正力を強化することで、障害部位を保護する。すなわち、膝関節の動揺を抑制することを目的とするため、第１カフ及びその他のカフは、装具アームに結合しており、カフが装具アームに対して回動することはない。したがって、患者は障害のある脚を頑丈な箱状の装具に入れて固定することで、膝の変形を矯正して膝痛を減少する。しかし、装具の骨組みが強固であるために、歩行動作（膝の屈伸運動）に伴い装具がずれる。更に、装具から受ける束縛感が装着に対する違和感が大きいために、長時間装着の妨げになっていた。
　装具のずれ防止としては、特許文献１にも見られるように、大腿骨内側上顆の上部の窪んだ部分に懸垂パッドを当て懸垂ベルトで抑え、さらに下腿の脹脛上部にアシストベルトを巻きつけて止める方法がある。特許文献１は、連結部材を有する装具に懸垂装置（懸垂アーム、懸垂パッド及び懸垂ベルト）を採用している。
　特許文献１で採用する方法は、装具のずれ防止に関しては従来の複数カフ構造の膝関節用装具においても有効である。 The knee joint orthosis has been considered to protect the damaged part by applying the splint principle, fixing the knee joint, which is an obstacle, to the splint, and correcting the knee deformation. The knee brace cuff is generally applied by adjusting the number of cuffs according to the level of injury of the patient. A conventional multi-cuff structure orthosis protects an obstacle site by strengthening support force / correction force more than a single cuff orthosis. That is, in order to suppress the shaking of the knee joint, the first cuff and the other cuffs are coupled to the appliance arm, and the cuff does not rotate with respect to the appliance arm. Therefore, the patient corrects the knee deformation and reduces knee pain by fixing the disabled leg in a sturdy box-like brace. However, since the skeleton of the brace is strong, the brace is displaced with the walking motion (the knee flexion and extension movement). Furthermore, since the sense of restraint received from the orthosis is uncomfortable with the wearing, it has been a hindrance to wearing for a long time.
In order to prevent the displacement of the brace, as seen in Patent Document 1, a suspension pad is applied to the recessed portion of the upper part of the femoral medial epicondyle and restrained with a suspension belt, and an assist belt is wound around the upper calf of the lower leg. There is a way to stop. Patent Document 1 employs a suspension device (a suspension arm, a suspension pad, and a suspension belt) for a device having a connecting member.
The method adopted in Patent Document 1 is also effective in a conventional knee joint device having a multi-cuff structure with respect to prevention of device displacement.

特開２０１１－１６７３６９号公報JP 2011-167369 A

　しかし、大腿が肥大した患者の場合では、大腿骨内側上顆の上部に窪みがないため、特許文献１による懸垂装置を用いても、装具のずれを防止する機能が弱くなる。
　そのため、特許文献１では、腓骨筋の上部、すなわち脹脛の最大膨れ部よりも上方に下腿下部バンドを配置することを提案している。
　しかし、懸垂装置が十分に機能せずに下腿下部バンドだけで装具のずれ落ちを防止する場合、下腿下部バンドを強く締める必要がある。そのため、腓骨神経を過度に締め付けることになってしまい、圧迫感で装着感が悪くなる上に、装具のずれ落ち防止の効果も十分ではない。
　また、下腿下部バンドのベルト幅を広げて締め付け力を緩和すると、下腿下部バンドが脹脛の最大膨れ部よりも下部に至ってしまい、脹脛の伸縮に伴って装具がずれる。よって、装具の装着に対する違和感なく、装具がずれなく長時間装着可能な膝関節用装具が求められていた。
　一方、膝関節に障害を持つ患者にとって、装具を装着時の外見的被視認性（装具装着を他人に認知されること）は気になることである。装具は、脚線に沿ったアームの形状の調整で多少のフィッティング性の改善は可能である。しかし、特に複数カフ構造の膝装具の場合、支持力・矯正力が強くなる分アームの形状の調整が難しくなっている。ズボンやスカートの着衣により他人に認知されないような脚線に沿った調整を、アームの形状調整だけで実現するのは難しかった。 However, in the case of a patient whose femur is enlarged, since there is no depression at the upper part of the medial epicondyle of the femur, even if the suspension device according to Patent Document 1 is used, the function of preventing the displacement of the brace becomes weak.
For this reason, Patent Document 1 proposes to arrange a lower leg lower band above the peroneal muscle, that is, above the maximum swollen portion of the calf.
However, when the suspension device does not function sufficiently and only the lower leg lower band prevents the orthosis from falling off, it is necessary to tighten the lower leg lower band strongly. For this reason, the radial nerve is excessively tightened, the feeling of wearing becomes worse due to the feeling of pressure, and the effect of preventing the device from falling off is not sufficient.
Further, when the belt width of the lower leg lower band is widened and the tightening force is eased, the lower leg lower band reaches below the maximum swollen part of the calf, and the orthosis shifts with expansion and contraction of the calf. Therefore, there has been a demand for a knee joint orthosis that can be worn for a long time without discomfort with the orthosis.
On the other hand, for a patient having a disorder in the knee joint, the apparent visibility when wearing the brace (being recognized by others) is anxious. The orthosis can be slightly improved by adjusting the shape of the arm along the leg line. However, especially in the case of a knee brace having a multi-cuff structure, it is difficult to adjust the shape of the arm because the supporting force and the correcting force are increased. It was difficult to achieve adjustments along leg lines that would not be recognized by others by wearing trousers or skirts, simply by adjusting the shape of the arm.

　そこで本発明は、支持力・矯正力を落とさないで、装具がずれなく、装着に対する違和感もないフィッティング性が改善された、長時間装着が可能な膝関節用装具であり、膝関節障害者であっても、健常者同様の日常生活が営める膝関節用装具を提供することを目的とする。 Therefore, the present invention is a knee joint orthosis that can be worn for a long time, with an improved fitting property that does not cause discomfort and does not feel uncomfortable without lowering the support force / correction force. Even if it exists, it aims at providing the orthosis for knee joints which can carry out daily life like a healthy subject.
