Description

この考案は、突き指などの外傷により生じた槌指に対し用いる、（固定力を強めた３点支持型）指装具に関するものである。 The present invention relates to a finger orthosis (three-point support type with increased fixing force) used for a mallet finger caused by an injury such as a fingertip.

従来の槌指に対する指装具は、セフティピン型（安全ピン型）などの三点支持型指装具が現在一般的に用いられる治療装具であり、本考案の原型である。ところが、このセフティピン型指装具は、従来指背おさえがフェルトなどの柔らかい素材であった。 As a conventional finger orthosis for a mallet finger, a three-point support type finger orthosis such as a safety pin type (safety pin type) is a treatment device generally used at present, and is a prototype of the present invention. However, in this safety pin type finger orthosis, the finger back is conventionally made of a soft material such as felt.

従来の外傷性の槌指に対する保存的治療としての指装具、特にセフティピン型などの三点支持型指装具において指背おさえがフェルトのみであるので、末節骨骨折のある槌指（骨性槌指）に対し、末節骨基部背側の遊離骨片を押さえる力が弱く、骨片が少し離開したまま骨癒合する事が非常に多かった。
本考案は、このような従来のセフティピン型指装具などの槌指用三点支持型指装具の固定力の弱さを補うためになされたものである。又、この為に考えられた本考案である指背おさえが硬質板である指装具は圧迫力が強いため、皮膚障害が起こりやすい。これを緩和するためにも本考案がなされる。In a conventional finger orthosis as a conservative treatment for a traumatic mallet finger, particularly a three-point support type finger orthosis such as a safety pin type, since only the felt back is made of felt, the hammer finger having a distal phalanx fracture (bone hammer) On the other hand, the force to hold the free bone fragments on the dorsal side of the distal phalanx to the finger was weak, and bone fusion was very often performed with the bone fragments slightly separated.
The present invention has been made in order to compensate for the weak fixing force of a three-point support type finger orthosis for hammer fingers such as the conventional safety pin type finger orthosis. In addition, the finger orthosis of the present invention, which is conceived for this purpose, in which the back of the finger is a hard plate, has a strong compression force, and thus easily causes skin disorders. The present invention is also made to alleviate this.

槌指用三点支持型指装具の指背おさえ（１）をアルミニウムや硬質プラスチックなどの硬質板（２）を主材とし、その裏地（３）として、フェルトやフォームラバーなどの柔軟な素材よりなる緩衝材とする。又、この硬質板及び裏地の緩衝材には通気孔（４）を持たせ、通気性を良くする。硬質板（２）の上面には、本体とを結ぶストラップ（５）が貼付される。
本考案は以上の構成よりなる指背おさえと指腹部を支える本体とを持つ槌指用三点支持型指装具である。The finger back support (1) of the three-point support type finger orthosis for hammer fingers is mainly made of a hard plate (2) such as aluminum or hard plastic, and its lining (3) is made of a flexible material such as felt or foam rubber. Cushioning material. In addition, the hard plate and the cushioning material of the lining are provided with ventilation holes (4) to improve air permeability. On the upper surface of the hard plate (2), a strap (5) for connecting to the main body is attached.
The present invention is a three-point support type finger orthosis for a hammer finger having a finger back support and a body for supporting a finger abdomen having the above configuration.

槌指用（三点支持型）指装具において可動性の指背おさえがアルミニウム又はプラスチックなどの硬質のものであるので、指背への圧迫力がよくかかり、外傷性の槌指、特に末節骨骨折のあるもので、骨片に対し従来のものより強い圧迫力が得られる。硬性の指背おさえの裏、つまり指背に当たる部分には、柔軟な素材として、フェルトやフォームラバーが介在するが、この硬質板および裏地には通気孔がある事により通気性が良くなり、この硬質の指背おさえによっておこる可能性のある皮膚の循環障害を防止あるいは軽減する事が出来る。 Since the movable finger back is made of a hard material such as aluminum or plastic in the hammer finger (three-point support type) finger orthosis, the compressive force is applied to the back of the finger, and the traumatic hammer finger, especially the distal phalanx With a fracture, a stronger compression force can be obtained on a bone fragment than conventional ones. Felt and foam rubber are interposed as a flexible material on the back of the hard finger back, that is, on the part that touches the back of the finger, but this hard plate and lining have ventilation holes so that ventilation becomes better. It is possible to prevent or reduce skin circulatory disturbance that may be caused by a rigid finger back.

以下、本考案の実施の形態について説明する。
アルミニウム又は硬質プラスチックなどの硬質板（２）で長さ（指の長軸方向）１０ｍｍ、横幅１４ｍｍ程度の大きさのものの裏面にフェルトなどの線維素材又はフォームラバーなどを貼付する。この硬質板（２）およびその裏地（３）には、通気性を持たせるために数ｍｍ程度の間隔で直径０．５〜３ｍｍ程度の通気孔（４）が開けられる。この指背おさえ（１）の硬質板（２）の上面にマジックテープ付ストラップ（５）を貼付する。この硬質板は、平面か、又は指の長軸方向にも横方向にも上面（指背面）凸の僅かな曲を持つ方が装着時に安定する。本考案である三点支持型指装具の本体は、従来より用いられているセフティピン型指装具などの指装具の本体をそのまま活用し、近位部（８）、遠位部（９）および両部を結合する両側面のループピン（７）よりなる。実際に外傷性の槌指（特に末節骨骨折）に対して用いる時は、本体（６）の近位部（８）、遠位部（９）をそれぞれ、指の中節および末節の指腹に当て、又、指背おさえ（１）を遠位指節間（ＤＩＰ）関節（１０）の背面に当て、指背おさえ上部のストラップ（５）を本体の両側面のループ（７）にかけ、締めて指背おさえの上でマジックテープで留める。Hereinafter, embodiments of the present invention will be described.
A fibrous material such as felt or foam rubber is attached to the back surface of a hard plate (2) of aluminum or hard plastic having a length (long axis of a finger) of about 10 mm and a width of about 14 mm. The hard plate (2) and its lining (3) are provided with ventilation holes (4) having a diameter of about 0.5 to 3 mm at intervals of about several mm in order to provide air permeability. A strap (5) with a magic tape is attached to the upper surface of the hard plate (2) of the finger back holder (1). This hard plate is more stable when worn when it has a flat surface or a slightly curved upper surface (rear surface of the finger) that is convex in both the major axis direction and the lateral direction of the finger. The body of the three-point support type finger orthosis of the present invention utilizes the body of a finger orthosis such as a conventionally used safety pin type finger orthosis as it is, and includes a proximal portion (8), a distal portion (9) and It consists of loop pins (7) on both sides connecting both parts. When actually used for a traumatic mallet finger (especially a distal phalanx fracture), the proximal part (8) and the distal part (9) of the main body (6) are respectively located on the middle and distal flank of the finger. The back of the finger (1) against the back of the distal interphalangeal (DIP) joint (10), the strap (5) on the top of the back of the finger and the loop (7) on both sides of the body, Tighten and fasten with velcro on finger back.
