Abstract

PROBLEM TO BE SOLVED: To solve problems in a cervical traction brace in which some patients complain of pain in a jaw, a temporomandibular joint and a tooth when using the cervical traction brace, and the patients complain of pain during cervical traction treatment, and therefore rest treatment is not possible for the patients with a proper traction force, however, there is no cervical traction brace compatible with this and capable of performing the safe and proper cervical traction treatment, also it is very troublesome to adjust the size of the brace according to an age difference and an individual difference, and the brace compatible with all sizes in one is not present.SOLUTION: In a cervical traction brace and a cervical traction brace unit worn on a patient's head when performing cervical traction treatment, a limit extension part not extending more than a predetermined length is provided in a jaw tool contained in the cervical traction brace, a portion of the traction connector, or in both of them.

Description

本発明は、頸椎の牽引治療時に使用する頸椎牽引装具及びその周辺部に関するものであり、特に、治療を受ける人が、牽引時に安全で効果的な牽引治療を行うことができる頸椎牽引装具を提供することを目的とする。    The present invention relates to a cervical traction device used in traction treatment of the cervical spine and its peripheral portion, and in particular, to provide a cervical traction device that allows a person receiving treatment to perform safe and effective traction treatment during traction. The purpose is to do.

頸椎牽引療法は、頸椎症の牽引療法として用いられており、整形外科やリハビリテーションなどの分野で広く用いられている。
頸椎牽引療法では、持続牽引と間欠牽引とに分けられる。
持続牽引は、一例として、患者をベッド上に安静に寝かせて、頸部をやや屈曲させ約５ｋｇの力で４５度の角度で後頭部を牽引する方法がある。目的は、頸椎部の動的因子を解消し、脊髄の安静を保持し、これによって脊髄循環を改善するためである。
間欠牽引は、一例として、患者を座位にとらせ、頚椎をやや屈曲させ約１０ｋｇの力で１０分間程度牽引する方法を繰り返す方法がある。目的は、頸部周囲筋の牽引によるマッサージ効果によって筋の血流改善と前角細胞への求心性刺激の減少による筋スパズム改善である。この方法によるマッサージ効果に伴い交感神経への作用により、上肢や手部にかかる血流増大効果も期待される。（非特許文献１） Cervical traction therapy is used as traction therapy for cervical spondylosis, and is widely used in fields such as orthopedics and rehabilitation.
Cervical traction therapy is divided into continuous traction and intermittent traction.
As an example of continuous traction, there is a method in which a patient is rested on a bed, the neck is slightly bent, and the occipital region is pulled at an angle of 45 degrees with a force of about 5 kg. The purpose is to eliminate dynamic factors of the cervical spine and maintain spinal cord rest, thereby improving spinal cord circulation.
As an example of intermittent traction, there is a method in which the patient is placed in a sitting position, the cervical vertebra is slightly bent, and traction is performed for about 10 minutes with a force of about 10 kg. The aim is to improve muscle spasm by improving muscle blood flow and reducing afferent stimulation to anterior horn cells by massage effect by pulling the peri-cervical muscle. Along with the massage effect by this method, the effect on the sympathetic nerve is also expected to increase blood flow on the upper limbs and hands. (Non-Patent Document 1)

頸椎牽引治療をする際は、必ず頸椎牽引装具を患者の頭部に装着しなければならず、患者の頸椎牽引装具の装着具合によっては、適正に牽引治療を施せない場合もある。
そこで、これまで様々な頸椎牽引装具が生み出されてきた。 When performing cervical traction treatment, the cervical traction device must be mounted on the patient's head, and depending on how the patient's cervical traction device is mounted, traction treatment may not be performed properly.
Thus, various cervical traction orthoses have been created so far.

従来の頸椎牽引装具の一例を図５に示す。図５（ａ）は特許文献１に記載の頸椎牽引装置の一例である。
図５（ａ）の装置は、牽引機構部及び制御部を包含する本体１、ワイヤー支持部３を有する牽引アーム２、ワイヤー５、頸椎牽引装具７とで構成され、患者を椅子４に着座させ患者の頭部に頸椎牽引装具７を装着させて治療する装置である。本体１の内部には牽引機構部、牽引力検出部、制御部、表示部及び操作部があり、牽引機構部にあるモータとモータに接続されたドラムによってワイヤー５を巻取り、ワイヤー５に接続された頸椎牽引装具７によって患者の頭部を牽引することで頸椎牽引治療を行う。
これは、一般的に用いられている牽引装置の一例であり、整形外科など身近な医療機関でよく見かける装置である。 An example of a conventional cervical traction device is shown in FIG. FIG. 5A is an example of a cervical traction device described in Patent Document 1. FIG.
5A includes a main body 1 including a traction mechanism and a control unit, a traction arm 2 having a wire support unit 3, a wire 5, and a cervical traction device 7, and a patient is seated on a chair 4. This is a device for treating the patient's head by attaching the cervical traction device 7 to the patient's head. The main body 1 includes a traction mechanism unit, a traction force detection unit, a control unit, a display unit, and an operation unit. The motor 5 in the traction mechanism unit and a drum connected to the motor wind the wire 5 and are connected to the wire 5. Cervical traction treatment is performed by pulling the patient's head with the cervical traction device 7.
This is an example of a traction device that is generally used, and is often found in familiar medical institutions such as orthopedics.

近年、頸椎牽引装具を使用する際、顎部や顎関節、歯などに疼痛を訴える患者がおり、頸椎牽引治療をする際、患者が疼痛を訴えるため、適正な牽引力で患者に対し安静な治療が行えないという問題が発生していることが判明した。
調査すると、原因は、頸椎牽引装具の装着具合によって、本来必要とする後頭部側への頸椎牽引がなされず、顎部へ牽引力が集中してしまうということであった。
そこで、現在、このような問題に対し適正に頸椎牽引治療が施せるような頸椎牽引装具が要求されている。 In recent years, when using cervical traction devices, some patients complain of pain in the jaw, temporomandibular joint, teeth, etc. It turned out that there was a problem that could not be done.
When investigated, the cause was that the cervical vertebral traction toward the occipital side, which was originally required, was not performed depending on how the cervical traction device was attached, and the traction force concentrated on the jaw.
Therefore, there is a need for a cervical traction device that can appropriately perform cervical traction therapy for such problems.

図５（ｂ）は特許文献１に記載の頸椎牽引装具の一例である。
図５（ｂ）の頸椎牽引装具は、頸椎牽引装具と牽引接続具（ハンガ）との組み合わせた状態を示している。この装具では、発生した衝撃から患者を保護するため、頚椎牽引装具を構成する部材の至る所に緩衝材又は伸縮する材料を設けている。
しかし、この装具では、ただ衝撃から患者を保護するために漠然と緩衝材を設けているだけであったため、ただ単に全体的な衝撃が柔らぐのみで、現在要求されている問題に対し具体的に効果を生じるものではなかった。 FIG. 5B is an example of the cervical traction device described in Patent Document 1.
The cervical traction device of FIG. 5B shows a state in which the cervical traction device and a traction connector (hanger) are combined. In this device, in order to protect the patient from the generated impact, a cushioning material or a material that expands and contracts is provided throughout the members constituting the cervical traction device.
However, with this brace, only shock absorbers were provided vaguely to protect the patient from impacts, so the overall impact was only softened, specifically addressing the issues currently required. It did not produce an effect.

図６は特許文献２に記載の頸椎牽引装具の一例である。
図６の頸椎牽引装具は、問題とする顎部に対して直接考慮した効果を有するが、後頭部のみを後頭部に当てただけの装具で牽引する方式であるため、装具に後頭部が的確にフィットしない場合、装具が滑って外れてしまう。また、従来の装具のような頭部をホールドする手段を有さない構造のため、あらゆる患者の後頭部のサイズに合わせることは、甚だ困難であり、様々な諸問題が発生することが考えられ、適正な頸椎牽引治療を施せるか疑問が残る。 FIG. 6 is an example of a cervical traction device described in Patent Document 2.
Although the cervical traction device shown in FIG. 6 has an effect that directly considers the jaw part in question, the cervical traction device does not fit the device correctly because the device is towed by a device that only applies the occipital region to the occipital region. If so, the brace slips off. In addition, because of the structure that does not have a means for holding the head like a conventional brace, it is extremely difficult to match the size of the back of the head of any patient, and various problems may occur. The question remains whether proper cervical traction therapy can be performed.

図７は特許文献３に記載の頸椎牽引装具の一例である。
図７の頸椎牽引装具は、頚椎牽引装具によって後頭部を優先的に牽引させる構造をとることで、患者を前屈姿勢にさせ、よって、顎の負担を和らげる効果を発生させている。
ただし、かかる装具は顎側のベルトの長さを毎回患者毎に調整しなければならないため、装着に大変手間である。また、ファスナを牽引金具のように牽引力がかかる部分に直接使用していることから、ファスナの劣化により牽引治療中に装具が外れることが想定されるため、大変危険である。 FIG. 7 is an example of a cervical traction device described in Patent Document 3.
The cervical traction device in FIG. 7 has a structure in which the occipital region is preferentially pulled by the cervical traction device, thereby causing the patient to bend forward and thereby reducing the burden on the jaw.
However, such an appliance is very troublesome to wear since the length of the belt on the chin side must be adjusted for each patient each time. Further, since the fastener is directly used in a portion where a traction force is applied like a traction metal fitting, it is assumed that the appliance is detached during the traction treatment due to the deterioration of the fastener, which is very dangerous.

頸椎牽引装具を使用する際、顎部や顎関節、歯などに疼痛を訴える患者がおり、頸椎牽引治療をする際、患者が疼痛を訴えるため、適正な牽引力で患者に対し安静な治療が行えないという問題があるが、これに対応することができ、且つ、安全で適正な頸椎牽引治療が施せる頸椎牽引装具がない。
また、年齢差、個人差により装具のサイズの調整をするのは非常に手間であるとともに、全てのサイズを１つで対応できる装具も存在しない。 When using the cervical traction device, some patients complain of pain in the jaw, temporomandibular joint, and teeth. There is no problem, but there is no cervical traction device that can deal with this problem and can perform cervical traction therapy safely and appropriately.
Further, adjusting the size of the brace due to age differences and individual differences is very troublesome, and there is no brace that can handle all sizes in one.

この機能を設けることで、患者のあらゆる頭部形状に装具を適応させることができ、制限伸長機能が有効に作用することで後頭部が牽引された後に顎部が牽引され、最初に顎部に牽引力が加わることが無くなり、頭部も前屈した状態で牽引されることとになる。
したがって、頸椎牽引治療において、頸椎牽引装具を使用する際、これまで顎部や顎関節、歯などに疼痛を訴えていた患者が減り、適正な牽引力で患者に対し安静な治療が施せるようになる。
また、年齢差、個人差があっても無調整で装具が適正に装着でき、適正な治療が施せるようになる。 The cervical vertebral traction device of the present invention is a material that is attached to a patient's chin and is stretchable on a part of the chin tool 1 or a hanger 32 applied to the chin tool in the chin tool 1 in which traction force is applied to the patient's chin. The structure is provided and the part provides a limited extension function that extends only to a certain length.
By providing this function, the brace can be adapted to any head shape of the patient, and the jaw extension is pulled after the back of the head is pulled by the effective extension and extension function. Will not be added, and the head will be pulled in a bent state.
Therefore, when using the cervical traction device in cervical traction therapy, the number of patients who have complained of pain in the jaw, temporomandibular joint, teeth, etc. has been reduced so that the patient can be treated with proper traction force. .
In addition, even if there are age differences and individual differences, the appliance can be properly worn without adjustment, and appropriate treatment can be performed.

本発明の請求項１に係る頸椎牽引装具についてその構造を図１に基づき説明する。
本発明に係る頸椎牽引装具は、図１において、顎部具１、顎緩衝材２、後頭部具３、後頭部緩衝材４、ファスナ５、留具Ａ６、留具Ｂ７、ハンガ８、ハンガ留具９からなる。
顎部具１と後頭部具３とはこの実施例では別個独立のものとしているが、取り扱いが煩雑で手間である場合は、一部に繋げる部材を設けることで一体の装具とすることができる。 The structure of the cervical traction device according to claim 1 of the present invention will be described with reference to FIG.
The cervical spine orthosis according to the present invention is shown in FIG. 1 with a jaw part 1, a jaw cushioning material 2, a back head part 3, a back head part cushioning material 4, a fastener 5, a clasp A 6, a clasp B 7, a hanger 8, and a hanger clasp 9. It consists of.
The chin tool 1 and the occipital tool 3 are separate and independent in this embodiment. However, when handling is troublesome and troublesome, it is possible to provide an integrated brace by providing a member connected to a part thereof.

図１の実施例では、装具の留具Ａ６、留具Ｂ７をそれぞれハンガ８のＡ、Ａ’、Ｂ、Ｂ’に留めた上で使用する。この実施例では、ハンガ８に留めた状態で一体の頸椎牽引装具ユニットとなる。そして、ハンガ留具９を図５（ａ）に記載のワイヤ５に取り付けることで牽引治療を行うことができる。    In the embodiment of FIG. 1, the fasteners A6 and B7 of the appliance are used after being fastened to A, A ', B and B' of the hanger 8, respectively. In this embodiment, the cervical traction device unit is integrated with the hanger 8. And traction treatment can be performed by attaching the hanger retainer 9 to the wire 5 shown in FIG.

顎部具１、後頭部具３の材質は、可撓性があり人体頭部にフィットし易い材質が良く、その一例として塩化ビニルレザー、合成皮革、樹脂繊維、ゴム、高分子エラストマー等が挙げられる。また、当該部具は、あらゆる患者の頭部にフィットする形状にする必要があるため、標準的なモデルを最初に決めておき、その後の様々な頭部形状に対する装着テストを行い、どのような頭部形状であってもおよそ適応できる形状にしておく。その際、装具が強く当たり、頭部の痛みが発生し易いポイントを把握しておき、緩衝材を設けて当該部分に対する痛みの軽減を図る。    The material of the chin part 1 and the back head part 3 is preferably a material that is flexible and easily fits the human head, and examples thereof include vinyl chloride leather, synthetic leather, resin fiber, rubber, and polymer elastomer. . In addition, since the device needs to be shaped to fit any patient's head, a standard model should be determined first, and then a variety of head shapes can be tested for mounting. Even if it is a head shape, it is made a shape that can be adapted approximately. At that time, the point where the orthosis hits strongly and the head pain is likely to occur is grasped, and a cushioning material is provided to reduce the pain on the part.

図１の実施例では、顎部や後頭部の各部分に顎緩衝材２、後頭部緩衝材４を設けているが、これはその一実施例であり、当該部分に限らず、必要とする適所に緩衝材を設けることが重要である。
緩衝材２、４の材質は、樹脂性又はゴム性のものを使用し、劣化防止及び耐久性向上のため、当該箇所の緩衝材の表面をコーティングするか、当該箇所を袋状にしておき緩衝材を挿入する等の手当てをしておくのが望ましい。
ファスナ５は、病院等で使用する場合、脱着頻度が高いため耐久性の良いものを選ぶことが望ましい。図１の実施例では、ファスナ５をオス側とし、顎部具の表面をファスナ５が取り付け可能となる生地を用いている。こうすることで、ファスナ５の取り付け位置に制約を持たさないようにし、あらゆる頭部形状に適応することが可能となる。
なお、ファスナ５の取り付け位置が確定できる場合は、装着する部分にファスナのメス側を設けておいても良い。 In the embodiment of FIG. 1, the chin cushioning material 2 and the occipital cushioning material 4 are provided in each part of the jaw and the occipital region. It is important to provide a cushioning material.
The material of the cushioning materials 2 and 4 is made of resin or rubber, and in order to prevent deterioration and improve durability, the surface of the cushioning material at the location is coated or the location is buffered. It is desirable to take care such as inserting materials.
When the fastener 5 is used in a hospital or the like, it is desirable to select a fastener having a high durability because of its high desorption frequency. In the embodiment of FIG. 1, the fastener 5 is the male side, and the cloth on which the fastener 5 can be attached is used on the surface of the jaw part tool. By doing so, it is possible to adapt to any head shape without restricting the attachment position of the fastener 5.
In addition, when the attachment position of the fastener 5 can be decided, you may provide the female side of the fastener in the part to mount.

図１の実施例では、顎部具１をハンガ８に取り付けるために留具Ｂ７設け、後頭部具３をハンガ８に取り付けるために留具Ａ６を設けている。
留具Ａ６、留具Ｂ７は、共に材質は金属性又は樹脂性で良いが、牽引力が繰り返し加えられる部分にあたるため、樹脂性を使用する場合は、強度に注意が必要である。 In the embodiment of FIG. 1, a fastener B <b> 7 is provided for attaching the jaw tool 1 to the hanger 8, and a fastener A <b> 6 is provided for attaching the back head tool 3 to the hanger 8.
Both the clasp A6 and clasp B7 may be made of metal or resin. However, since the strut is a portion where traction force is repeatedly applied, attention should be paid to the strength when using resin.

本発明の特徴を示す制限伸長部を図２に基づき説明する。
図２（ａ）は、顎部具１をハンガ８に繋げる部分の一部である。ここで留具Ｂ７に繋ぐ帯の部分を伸縮する材料にする。ただし、伸縮するだけではなく、一定の長さまでしか伸びない構造を有する材料とする。例えば、織りゴムや平ゴムを織り込んだベルトなどであり、当該機能を有する帯を用いる。一定の長さとは、使用する目的によって様々であるが、通常の場合１〜１５ｃｍであれば足りる。また、当該部分は、牽引力が繰り返し加えられる部分であるため、安全性を確保するため品質を優先し、事前に十分な耐久試験をしておく必要がある。 The limiting extension part showing the features of the present invention will be described with reference to FIG.
FIG. 2 (a) is a part of a portion that connects the chin tool 1 to the hanger 8. Here, the part of the belt connected to the fastener B7 is made of a material that expands and contracts. However, the material has a structure that not only expands and contracts but also extends only to a certain length. For example, a belt woven with woven rubber or flat rubber is used, and a band having the function is used. The fixed length varies depending on the purpose of use, but is usually 1 to 15 cm. Moreover, since the said part is a part to which tractive force is repeatedly applied, in order to ensure safety, it is necessary to give priority to quality and to conduct a sufficient durability test in advance.

このような機能を設けた際、生じる作用効果について図４（ａ）（ｂ）に基づき説明する。
図４（ａ）は従来の頸椎牽引装具の人体装着図であり、図４（ｂ）は本発明の制限伸長部を設けた頸椎牽引装具の人体装着図である。
従来は、装具を牽引した際、図４（ａ）に示すとおり装具が一体となって頭部を牽引するため、顎部と後頭部が同時に牽引される。
ここで図を見ると判り易いが、後頭部は装具がズレ易く、顎部は装具がズレ難い。したがって、頭部形状により仕方ないことであり、従来の装具であれば、後頭部を牽引するよりも顎部を牽引する方がより確実に牽引できてしまう。
このため、場合によっては、顎部に優先的に牽引力が加わってしまい、前述した顎部や顎関節、歯などに疼痛を訴える患者が発生してしまう。
そこで、顎部ではなく後頭部に優先的に牽引力が加わるような機能を施したのが本発明の頸椎牽引装具である。 The effects produced when such a function is provided will be described with reference to FIGS.
4A is a human body wearing view of a conventional cervical traction device, and FIG. 4B is a human body wearing view of a cervical traction device provided with a limiting extension part of the present invention.
Conventionally, when the brace is towed, the brace and the back of the head are pulled simultaneously because the brace is pulled together as shown in FIG.
Here, it is easy to understand by looking at the figure, but the brace is easy to shift the orthosis, and the jaw is difficult to shift the brace. Therefore, it is unavoidable depending on the shape of the head, and if it is a conventional brace, it will be able to tow the jaw part more reliably than tow the back head.
For this reason, depending on the case, a traction force is preferentially applied to the jaw part, and a patient who complains of pain in the above-described jaw part, temporomandibular joint, tooth, etc. occurs.
Therefore, the cervical traction device of the present invention is provided with a function that preferentially applies a traction force to the occipital region rather than the jaw.

図４（ｂ）は本発明の頸椎牽引装具の構造説明図である。
図を見ると判るが、適正な制限伸長部４１を頚椎牽引装具の図示する部分に設けることで、牽引当初は後頭部具３に優先的に牽引力が加わり、制限伸長部４１によって後から追随するよう顎部具１に牽引力が加わることになり、顎部には牽引力が直後にかかることが無くなった。
しかし、単なる伸縮性を有する部材を用いた場合、当該部材は牽引によって延々と伸びてしまい、適正に牽引力を頭蓋に伝えられず、適正な頸椎牽引治療を施せない。 FIG. 4B is a structural explanatory view of the cervical traction device of the present invention.
As can be seen from the figure, by providing an appropriate limited extension 41 in the illustrated portion of the cervical traction device, a traction force is preferentially applied to the occipital device 3 at the beginning of traction so that the limited extension 41 can follow it later. A traction force is applied to the jaw part 1 and no traction force is immediately applied to the jaw part.
However, when a member having a simple stretchability is used, the member stretches endlessly by traction, and the traction force cannot be properly transmitted to the skull, so that proper cervical traction therapy cannot be performed.

そこで、本発明では、当該伸縮する部材に一定の長さ以上は伸びない機能を設けることで適正に牽引力を頭蓋に伝えられる機能を設けた。
したがって、これまで問題であった、顎部を牽引されることで顎部や顎関節、歯などに疼痛が発生する事が無くなった。
また、同様の効果から、後頭部を優先的に牽引し頭部が前屈する姿勢で牽引したとしても、適正に牽引力が頭蓋に直接作用するようになることで、適正な牽引治療を行うことができる。
また、顎部具３が伸縮性を有するため、顎部に簡単に装着し易くなり、装着に関し煩わしさが無くなった。
また、長期間使用していくうち伸縮性が劣化してしまい破損したとしても、一定の長さの基材の強度は未だ劣化せず保持できているため突然の断裂による危険性も防ぐことが可能となる。 Therefore, in the present invention, a function for properly transmitting the traction force to the cranium is provided by providing the member that expands and contracts with a function that does not extend beyond a certain length.
Therefore, the jaws, temporomandibular joints, teeth, etc. are no longer painful by pulling the jaws, which has been a problem until now.
In addition, from the same effect, even if the head is pulled in a posture that preferentially pulls the back of the head and the head is bent forward, it is possible to perform appropriate traction treatment by appropriately applying the traction force directly to the skull. .
Moreover, since the jaw part tool 3 has elasticity, it became easy to attach to a jaw part easily, and there was no troublesome about attachment.
In addition, even if the stretchability deteriorates and breaks after long-term use, the strength of the base material of a certain length can still be maintained without deterioration, thus preventing the risk of sudden tearing. It becomes possible.

なお、この実施例では、後頭部具３は伸縮性が無いものとして説明しているが、要旨は後頭部具３に優先的に牽引力が加えられれば良いため、後頭部具３に顎部具１と同様の制限伸長部を設けて顎部具１と後頭部具３の伸縮強度に差異を設けて同様の機能を持たせることも可能である。    In this embodiment, the occipital tool 3 has been described as having no stretchability. However, the gist of the occipital tool 3 may be preferentially applied to the occipital tool 3, so that the occipital tool 3 is similar to the chin tool 1. It is also possible to provide a similar function by providing a difference in the expansion / contraction strength between the jaw part tool 1 and the occipital part tool 3 by providing a limited extension part.

図２（ｂ）は、別の一実施例であり、図２（ａ）の織りゴム２１の代わりに伸縮性ｂのゴムバンド２３と非伸縮材のベルト２２を別個に設ける。この際、材質の選定及び形状設計は、前述した方法で同様に行う。
この構造を用いると一定の伸びる長さ、及び伸びを制限する長さを簡単に調整変更することが可能となる。 FIG. 2B shows another embodiment, in which a stretchable b rubber band 23 and a non-stretchable belt 22 are separately provided in place of the woven rubber 21 shown in FIG. At this time, material selection and shape design are performed in the same manner as described above.
When this structure is used, it is possible to easily adjust and change a certain length of extension and a length that limits the extension.

図２（ｃ）は、別の一実施例であり、図２（ａ）の織りゴム２１の代わりに留具Ｂ７を制限伸長部４１としたものである。当該留具の外周を構成するゴムリング金具２５は従来の留具Ｂ７と同材質で良いが、その内側にゴムリング２７を設ける。ゴムリング２７によって顎部具１に伸縮性を持たせ、ゴムリング金具２５によってその伸びしろに制限を設ける。ここでゴムリング２７は牽引力が繰り返し加えられる部分であるため、高強度のゴムを設ける必要がある。一般のゴムリングで強度不足であれば、リニアダンパーなどを使用する事も可能である。
この構造を用いると、顎部具１の伸縮性を表す弾性をより精度良く一定にすることが可能となる。 FIG. 2 (c) shows another embodiment, in which a clip B7 is used as the limiting extension 41 instead of the woven rubber 21 shown in FIG. 2 (a). The rubber ring metal fitting 25 constituting the outer periphery of the fastener may be made of the same material as the conventional fastener B7, but a rubber ring 27 is provided on the inside thereof. The jaw ring 1 is made stretchable by the rubber ring 27, and the stretch allowance is limited by the rubber ring metal fitting 25. Here, since the rubber ring 27 is a portion where traction force is repeatedly applied, it is necessary to provide high strength rubber. If the strength is insufficient with a general rubber ring, a linear damper or the like can be used.
If this structure is used, it will be possible to make the elasticity representing the stretchability of the jaw unit 1 constant with higher accuracy.

図３は、別の一実施例であり、制限伸長部４１をハンガ８におけるハンガ緩衝材３２に設けたものである。
図３において、ハンガ８はハンガ金具３１、ハンガ緩衝材３２で構成される。ここで、ハンガ緩衝材３２のＢ、Ｂ’の箇所を弾力性もしくは伸縮性のある材質にし、当該部分が伸び切らないよう、適正な位置まで伸びるとハンガ金具３１で留まるようにしておく。
この構造を用いると、装具が従来の頸椎牽引装具であってもハンガ８を取り替えるだけで本発明と同様の機能を有する頸椎牽引装具にすることが可能となる。 FIG. 3 shows another embodiment, in which the limit extension 41 is provided on the hanger cushion 32 in the hanger 8.
In FIG. 3, the hanger 8 includes a hanger fitting 31 and a hanger cushioning material 32. Here, the portions B and B ′ of the hanger cushioning material 32 are made of an elastic or stretchable material so that the hanger metal fitting 31 stays at the proper position so that the portion does not fully extend.
By using this structure, even if the orthosis is a conventional cervical traction device, it is possible to obtain a cervical traction device having the same function as that of the present invention only by replacing the hanger 8.
