Description
本発明は、関節に装着して使用する関節アシスト装置及びこの関節アシスト装置の調整方法に関する。 The present invention relates to a joint assist device used by being mounted on a joint, and a method for adjusting the joint assist device.
特許文献１に示すように、本発明者は、装具の主要構造部材をアルミ合金で構成した装具を実用化している。本発明は、その装具の問題点を解決して装具性能の飛躍的改善と品質の安定化及び装着性の向上を実現しようとするものである。
アルミ合金製装具の第一の問題点は、患者の症状に合せて装具アームの形状を最終調整しても、使用により装具アームが繰返し荷重を受けることで塑性変形して、よって、調整時の矯正力を持続的に発揮しなくなることである。第二の問題点は、アルミが汗の塩分等により腐食をして破損の原因となることである。第三の問題点は、患者が金属製の装具を装着して航空機へ搭乗する際に、金属探知機により金属が探知され、確認検査を受けなければならないことである。
これら前記の問題点を改善し、従来装具よりも軽量で性能と装着感が改良された装具を提供することが求められている。
As shown in Patent Document 1, the present inventor has put into practical use an appliance in which the main structural member of the appliance is made of an aluminum alloy. The present invention is intended to solve the problems of the orthosis and realize dramatic improvements in the performance of the orthosis, stabilization of quality, and improvement of wearability.
The first problem with aluminum alloy braces is that even if the shape of the brace arm is finally adjusted according to the patient's symptoms, the brace arm is plastically deformed by repeated loading due to use, and therefore the It means that the corrective power is not exhibited continuously. The second problem is that aluminum corrodes due to the salt content of sweat and causes damage. The third problem is that when a patient wears a metal brace and gets on an aircraft, the metal must be detected by a metal detector and subjected to a confirmation test.
There is a need to improve the above-mentioned problems and to provide a brace that is lighter than conventional braces and has improved performance and feel.
特許文献１又は特許文献２によるアルミ製装具においては、アルミの塑性を利用して患者の症状に合せてアーム形状と連結部材を調整することができる。しかし、使用中の繰返し荷重によりアルミアームの形状を変化させ、初期の矯正力を維持できなくなる。従って患者の体形や症状に合せてアームの形状を調整でき、使用中の繰返し荷重に対して塑性変形をしない装具の実用化が期待されていた。
関節装具のアーム部を樹脂で構成した装具はすでに実用化されている。その装具の構造材は頑丈なものが多く、使用中に形状変化する心配はないけれども、患者の症状に合せてアームの形状または連結部材を調整することを意図していない。
In the aluminum orthosis according to Patent Document 1 or Patent Document 2, the arm shape and the connecting member can be adjusted according to the patient's symptoms using the plasticity of aluminum. However, the shape of the aluminum arm is changed by the repeated load during use, and the initial correction force cannot be maintained. Therefore, the arm shape can be adjusted according to the patient's body shape and symptom, and the practical use of the brace which does not undergo plastic deformation with respect to the repeated load during use has been expected.
An orthosis in which the arm portion of a joint orthosis is made of resin has already been put into practical use. The brace structure is often rugged and does not worry about shape changes during use, but is not intended to adjust the shape of the arm or the connecting member to the patient's symptoms.
そこで、本発明は、使用者の体形にフィットした調整が可能となり装具装着の被視認性を改善することができる関節アシスト装置及びこの関節アシスト装置の調整方法を提供することを目的とする。 Therefore, an object of the present invention is to provide a joint assist device that can be adjusted to fit the user's body shape and can improve the visibility of the wearing of the brace and a method for adjusting the joint assist device.

請求項３記載の本発明は、請求項１又は請求項２に記載の関節アシスト装置において、前記短繊維強化熱可塑性樹脂、前記長繊維強化熱可塑性樹脂、及び前記布強化熱可塑性樹脂に、炭素繊維、ガラス繊維、ボロン繊維、アラミド繊維、ポリエチレン繊維、ザイロン、及び液晶ポリマーのいずれか一種又は複数種を用いたことを特徴とする。
請求項４記載の本発明は、請求項１から請求項３のいずれかに記載の関節アシスト装置の調整方法であって、変形の必要性を判断する判断ステップと、前記判断ステップで変形の必要性があると判断した場合に変形量を計測する計測ステップと、少なくとも前記第１の内側アーム、前記第１の外側アーム、前記第２の内側アーム、及び前記第２の外側アームを加熱する軟化処理ステップと、軟化させた前記第１の内側アーム、前記第１の外側アーム、前記第２の内側アーム、及び前記第２の外側アームに変形処理を行う変形処理ステップと、少なくとも前記第１の内側アーム、前記第１の外側アーム、前記第２の内側アーム、及び前記第２の外側アームを冷却する硬化処理ステップとを有することを特徴とする。
According to a first aspect of the present invention, there is provided the joint assist device according to the first aspect, wherein the inner support plate disposed inside the joint, the outer support plate disposed outside the joint, the inner support plate, and the outer support plate are moved backward. A connecting member connected on the knee side, a first inner arm rotatably provided on the upper end side of the inner support plate, and a second inner arm rotatably provided on the lower end side of the inner support plate A joint assisting device comprising: a first outer arm rotatably provided on an upper end side of the outer support plate; and a second outer arm rotatably provided on a lower end side of the outer support plate. there, the first inner arm, said first outer arm, the second inner arm, before Symbol second outer arm, and the connecting member is constituted by a thermoplastic resin, wherein the first inner An arm, the first outer arm, the second inner arm, Fine the second outer arm and short fiber reinforced thermoplastic, characterized in that the connecting member has a long fiber-reinforced thermoplastic resin or fabric-reinforced thermoplastic resin.

One or more of fiber, glass fiber, boron fiber, aramid fiber, polyethylene fiber, zylon, and liquid crystal polymer are used.
A fourth aspect of the present invention is the joint assist device adjusting method according to any one of the first to third aspects, wherein a determination step for determining the necessity of deformation and the necessity for deformation at the determination step are provided. A measuring step for measuring the amount of deformation when it is determined that there is a possibility, and softening for heating at least the first inner arm, the first outer arm, the second inner arm, and the second outer arm A processing step, a deformation processing step for performing a deformation processing on the softened first inner arm, the first outer arm, the second inner arm, and the second outer arm, and at least the first And a curing process step for cooling the inner arm, the first outer arm, the second inner arm, and the second outer arm.
本発明の関節アシスト装置によれば、着用者の体形にフィットした調整が可能である。
関節アシスト装置において要求される機能の第一は、変形性膝関節症の矯正力即ち支持力である。アルミに比してはるかに剛性に優れる炭素繊維強化樹脂を装具アームに採用することで、装具アームが受ける繰り返し荷重で塑性変形するため、患者に合せて調整した矯正力が落ちることはない。更に発明者らの経験によると、患者の症状のレベルにもよるが、装具装着の被視認性、即ち装具を装着していること、を他人に認知されることを忌避する傾向が強いということがわかった。しかし、本発明の関節アシスト装置は、装具装着の被視認性を改善することができる。
アルミ構造材は汗の塩分などによって腐食破損を起こしやすいが、樹脂化することで腐食破損の問題も解決できる。
更に金属製の膝装具を装着して航空機搭乗をする際に、金属探知機により金属が探知され、確認検査を受ける等の煩わしさが生じる。オールプラスチック装具であれば金属探知機に探知されることはなくなる上に、装具の軽量化も可能である。その結果、着用者にとって日常生活を支障なく過ごす膝装具を提供できる。
According to the joint assist device of the present invention, adjustment that fits the wearer's body shape is possible.
The first function required in the joint assist device is the correction force or support force of knee osteoarthritis. By adopting a carbon fiber reinforced resin, which is much more rigid than aluminum, for the brace arm, the orthodontic arm undergoes plastic deformation under repeated loads, so that the correction force adjusted for the patient does not drop. Furthermore, according to the experience of the inventors, although depending on the level of symptoms of the patient, there is a strong tendency to avoid being recognized by other people that the visibility of the wearing of the brace, that is, wearing the brace. I understood. However, the joint assist device of the present invention can improve visibility of wearing of the brace.
Aluminum structural materials are prone to corrosion damage due to the salt content of sweat, etc., but the problem of corrosion damage can be solved by using resin.
Further, when a user wears a metal knee brace to board an aircraft, the metal detector detects the metal, and troubles such as receiving a confirmation inspection occur. An all-plastic device will not be detected by a metal detector, and the weight of the device can be reduced. As a result, it is possible to provide a knee brace that allows the wearer to spend daily life without hindrance.

次に図５及び図６を用いて本実施例による関節アシスト装置の装着方法について説明する。
図５は本実施例による関節アシスト装置を装着した状態を示す側面図、図６は同装置を装着した状態を示す正面図である。
外側支持板１ａは大腿骨外側上顆１０１の上方に配置され、内側支持板１ｂは大腿骨内側上顆１０２の上方に配置する。従って、外側パット５０ａは大腿二頭筋１０３の下部に位置し、内側パット５０ｂは半腱様筋１０４の下部に位置する。内側パット５０ｂは弾性接続部６０ｂによって第１の内側アーム１０ｂに懸架されており、第３のバンド４３は接続部６０ａによって第１の外側アーム１０ａに接続されている。そのため、第３のバンド４３による締め付けによって内側パット５０ｂは半腱様筋１０４に密着する。また第３のバンド４３による締め付けによって第１の外側アーム１０ａには大腿骨１０５の方向に力が加わるため、外側支持板１ａにも大腿骨１０５の方向に力が加わり、外側パット５０ａは大腿二頭筋１０３に密着する。このように内側パット５０ｂは半腱様筋１０４の位置に、外側パット５０ａは大腿二頭筋１０３の位置に配置されるために押圧による密着性が高い。その結果、内側パット５０ｂは大腿骨内側上顆１０２によってずれ落ちを防止でき、外側パット５０ａは大腿骨外側上顆１０１によってずれ落ちを防止できる。
Next, a method for mounting the joint assist device according to the present embodiment will be described with reference to FIGS.
FIG. 5 is a side view showing a state where the joint assist device according to the present embodiment is mounted, and FIG. 6 is a front view showing a state where the device is mounted.
The lateral support plate 1a is disposed above the femoral lateral epicondyle 101, and the medial support plate 1b is disposed above the femoral medial epicondyle 102. Accordingly, the outer pad 50 a is located at the lower part of the biceps femoris 103 and the inner pad 50 b is located at the lower part of the semitendon-like muscle 104. The inner pad 50b is suspended from the first inner arm 10b by an elastic connecting portion 60b, and the third band 43 is connected to the first outer arm 10a by a connecting portion 60a. Therefore, the inner pad 50 b comes into close contact with the semi-tendon-like muscle 104 by tightening with the third band 43. Further, since the force is applied to the first outer arm 10a in the direction of the femur 105 by the tightening by the third band 43, the force is also applied to the outer support plate 1a in the direction of the femur 105, and the outer pad 50a is Close contact with the head muscle 103. Thus, since the inner pad 50b is disposed at the position of the semi-tendon-like muscle 104 and the outer pad 50a is disposed at the position of the biceps femoris 103, adhesion by pressing is high. As a result, the medial pad 50b can be prevented from slipping by the femoral medial epicondyle 102, and the lateral pad 50a can be prevented from slipping by the femur lateral epicondyle 101.
また、第２のバンド４２は腓腹筋１０６の上部、すなわち腓腹筋１０６の最も大きな位置よりも上方、に配置することで、第２のバンド４２のずれ落ちも防止できる。
下肢の姿位によって異なるが、極度な内反膝の場合を除き、内側支持板１ｂの位置に対して、第２の内側アーム２０ｂのピン２２ｂは頸骨１０７の方向に寸法ｗ３だけ近くなる。このとき、第２の内側アーム２０ｂは、内側支持板１ｂに対して回動するとともにピン２２ｂに対しても所定範囲で回動しなければならないため、第２の内側アーム２０ｂの中間部で傾斜面２０ｘを構成する必要がある。しかし、この傾斜面２０ｘを大腿骨内側顆１０８から頸骨１０７上部に沿わせることで、特に内側支持板１ｂ及び第２の内側アーム２０ｂを、大腿部１０９から下腿部１１０に沿った状態に配置することができる。
従って、膝蓋骨１１１の両側部には、第２の外側アーム２０ａと第２の内側アーム２０ｂが位置することになる。
Further, the second band 42 is disposed above the gastrocnemius muscle 106, that is, above the largest position of the gastrocnemius muscle 106, so that the second band 42 can be prevented from slipping off.
The pin 22b of the second inner arm 20b is close to the position of the inner support plate 1b by the dimension w3 in the direction of the tibia 107 except for an extreme varus knee, although it depends on the posture of the lower limbs. At this time, since the second inner arm 20b must rotate with respect to the inner support plate 1b and also with respect to the pin 22b within a predetermined range, the second inner arm 20b is inclined at an intermediate portion of the second inner arm 20b. It is necessary to configure the surface 20x. However, by placing the inclined surface 20x along the femoral medial condyle 108 and the upper part of the tibia 107, the medial support plate 1b and the second medial arm 20b are brought into a state along the crus 110 from the femur 109. Can be arranged.
Accordingly, the second outer arm 20a and the second inner arm 20b are positioned on both sides of the patella 111.

ステップ２において、これらの標準品の中から使用者に最も適したサイズの関節アシスト装置が選択される。
そして、ステップ２で選択した関節アシスト装置を仮装着し（ステップ３）、変形の必要性を判断する（ステップ４）。
Next, a method for adjusting the joint assist device according to the present embodiment will be described with reference to FIG.

It is a front view which shows the appliance frame of the state which was made.
First, a joint assist device as a standard product is produced (step 1). In the standard product, the first outer arm 10a, the first inner arm 10b, the second outer arm 20a, the second inner arm 20b, and the connecting member 30 are each formed by injection molding, and thereafter from FIG. It is assembled in the state shown in FIG. The standard product is manufactured in advance in several sizes according to the body shape.
In step 2, a joint assist device having a size most suitable for the user is selected from these standard products.
Then, the joint assist device selected in step 2 is temporarily mounted (step 3), and the necessity for deformation is determined (step 4).
図８は、ステップ３における関節アシスト装置の仮装着状態を示している。
ステップ４において、変形の必要があれば、変形量の計測を行う（ステップ５）。
ステップ５における変形量の計測の後に関節アシスト装置を取り外し（ステップ６）、関節アシスト装置の軟化処理を行う（ステップ７）。関節アシスト装置の軟化処理は、加熱によって行う。例えば、第１の外側アーム１０ａ、第１の内側アーム１０ｂ、第２の外側アーム２０ａ、第２の内側アーム２０ｂ、及び連結部材３０の中で必要部材又は必要部位に熱風を吹き付ける。
ステップ７における軟化処理の後に、第１の外側アーム１０ａ、第１の内側アーム１０ｂ、第２の外側アーム２０ａ、第２の内側アーム２０ｂ、及び連結部材３０の中で必要部材又は必要部位の変形処理を行う（ステップ８）。
ステップ８における変形処理の後に、特に変形処理部材又は変形処理部位を冷却して硬化処理を行う（ステップ９）。なお、硬化処理は、冷風を吹き付け、又は冷却ガスの吹き付けによって強制的に冷却する場合に限らず、自然冷却であってもよい。
ステップ９による硬化処理の後に、再度仮装着を行い（ステップ３）、変形の必要性を判断する（ステップ４）。
ステップ４において変形の必要性が無いと判断されると、関節アシスト装置の調整は完了する（ステップ１０）。
FIG. 8 shows a provisional wearing state of the joint assist device in step 3.
If there is a need for deformation in step 4, the amount of deformation is measured (step 5).
After the deformation amount is measured in step 5, the joint assist device is removed (step 6), and the joint assist device is softened (step 7). The softening process of the joint assist device is performed by heating. For example, hot air is blown to a necessary member or a necessary part in the first outer arm 10a, the first inner arm 10b, the second outer arm 20a, the second inner arm 20b, and the connecting member 30.
After the softening treatment in Step 7, the necessary members or necessary portions of the first outer arm 10a, the first inner arm 10b, the second outer arm 20a, the second inner arm 20b, and the connecting member 30 are deformed. Processing is performed (step 8).
After the deformation process in step 8, in particular, the deformation process member or the deformation process part is cooled to perform the curing process (step 9). The curing process is not limited to the case where cooling is forcedly performed by blowing cold air or cooling gas, and natural cooling may be used.
After the curing process in step 9, temporary mounting is performed again (step 3), and the necessity for deformation is determined (step 4).
If it is determined in step 4 that there is no need for deformation, the adjustment of the joint assist device is completed (step 10).
図９は、ステップ１０で調整が完了した関節アシスト装置の装着状態を示している。
なお、図７における処理流れは、標準品としての関節アシスト装置を制作し、その後標準品を選択するステップを含めて説明した。しかし、既に関節アシスト装置を着用している使用者が、所定期間経過後に関節アシスト装置を再調整する場合にも適用できる。関節アシスト装置の再調整にあっては、ステップ３からの処理流れとなる。
また、本実施例の説明では、関節アシスト装置を図１から図３に示す状態に完成させた後の調整方法として説明した。しかし、図４に示す装具フレームの状態で調整を行うこともできる。装具フレームの状態で調整を行う場合には、装具フレーム以外の部材を治具として装具フレームの仮装着を行う。
また、他の方法としては、ステップ３からステップ５の工程を、データを用いたシミュレーションで行うこともできる。シミュレーションで行う場合には、使用者の装着部位に関する寸法データをあらかじめ計測して入力する。寸法データは画像データを用いてもよい。その場合、三次元立体模型をシミュレートし、シミュレートした三次元立体模型に選択した装具（部材）を適用することで、変形の必要性の判断と、変形量の算出を行う。
FIG. 9 shows a mounted state of the joint assist device that has been adjusted in Step 10.
The processing flow in FIG. 7 has been described including the step of producing a joint assist device as a standard product and then selecting the standard product. However, the present invention can also be applied to a case where a user who has already worn the joint assist device readjusts the joint assist device after a predetermined period has elapsed. In the readjustment of the joint assist device, the processing flow from step 3 is performed.
In the description of this embodiment, the adjustment method after the joint assist device is completed in the state shown in FIGS. 1 to 3 has been described. However, the adjustment can also be performed in the state of the appliance frame shown in FIG. When the adjustment is performed in the state of the appliance frame, the appliance frame is temporarily attached using a member other than the appliance frame as a jig.
As another method, the processes from step 3 to step 5 can be performed by simulation using data. In the case of simulation, dimension data relating to the user's wearing part is measured and input in advance. Image data may be used as the dimension data. In that case, the three-dimensional model is simulated, and the selected equipment (member) is applied to the simulated three-dimensional model, thereby determining the necessity of deformation and calculating the amount of deformation.
本発明の関節アシスト装置は、半身麻痺のリハビリやポリオなどの反張膝用、Ｏ脚、Ｘ脚や関節リュウマチなどの変形性関節用、靱帯損傷や半月板損傷などのスポーツ用としてだけでなく、膝や肘などの関節に負担のかかる作業者にも広く用いることができる。 The joint assist device of the present invention is used not only for reflexive knees such as rehabilitation of hemiplegia and polio, for deformable joints such as O-legs, X-legs and rheumatoid arthritis, and for sports such as ligament damage and meniscal damage. It can also be widely used by workers who place a burden on joints such as knees and elbows.
