Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an orthosis for preventing and treating ankle sprains and contusions, particularly injuries to the tibiofibular joint ligament, deltoid ligament, lateral collateral ligament, etc. It is something.

(bl) Conventional technology When a joint is moved by internal and external forces beyond its physiological range of motion, the ligaments and joint capsule that reinforce the joint are damaged.

A sprain is when the relationship between the joint surfaces is still normal after this damage, and a sprain is when the joint surfaces become misaligned due to this damage. Therefore, joints whose range of physiological motion is originally limited to only one direction are more likely to suffer such damage. Also, from one perspective, since these joints are not ball and socket joints, they often rely on reinforcements such as ligaments and elbows, so W
4 @ It can be said that it is easy to do.

Sprains are especially common when you put equipment on your body while playing sports.
This is easy to occur because the direction of movement is unilaterally restricted, and is very common in the case of skiing.

Treatment (although surgical therapy is also available for severe cases) is to apply a cold compress to stop the bleeding, a warm compress to promote the absorption of the bleeding, in this order, followed by fixation with only a bandage (taping). ), or by wearing special braces or other methods such as splints or casts.

Of these, taping and wearing special braces are used not only as treatment, but also to preserve joints after splints or casts are removed, or as preventive measures when such injuries are expected, such as when skiing. or

Taping provides a good fit because it can be performed according to the case, and is often used in sports clubs and the like that have dedicated trainers.

Although the usage of dedicated braces is not as great as that of taping, they have the advantage of not requiring any special techniques to wear them.

(C) Problems to be Solved by the Invention However, such taping and conventional specialized braces have various drawbacks, and it is difficult to say that they are the best preventive devices or therapeutic aids.

First of all, taping has disadvantages such as being prone to rashes, metal fittings being used to fasten the ends of the bandage, and the fact that it spoils quickly and is almost disposable, increasing the cost required for complete recovery. One drawback is that the procedure requires very advanced techniques. In other words, there are various types and severity of injuries, and taping must be applied depending on each individual.For example, excessive tightening may cause circulation disorders, or hematoma in soft tissue may occur, which may worsen the injury. There are cases where this procedure has been performed, and there is always the problem that it can only be performed by experienced doctors or specialized trainers.

Next, conventional specialized braces have the drawbacks of being high-tension and difficult to adjust. Among these, the drawback regarding adjustment is particularly serious because if it cannot be adjusted according to the degree of detonation during the healing stage, healing will be delayed. Furthermore, conventional dedicated orthoses have the disadvantage of being extremely lacking in versatility, which leads to the disadvantage that they are difficult to manufacture as ready-made products and are expensive.

(d) Means for Solving the Problems In view of the above points, the inventors of the present invention have conducted extensive research over many years, and as a result have developed an extremely versatile orthosis for ankle joint disorders. Its features include a heel encasement made of a flexible material with a window opening to expose a portion of the heel, and a heel encasement that secures the core to the heel while wrapping around the ankle and instep. It consists of a belt part that fixes the rotation, so it is lightweight, feels very comfortable to wear, and does not require any special skills to wear.
This orthosis has the advantages of being able to easily accommodate various symptoms and individual differences.

In order to solve the various problems mentioned above, the present inventor has developed a soft orthosis for preventing and treating sprains or contusions of the ankle joint, in which a part of the foot has a curved inner surface that wraps around the heel. Invented an ankle orthosis that is composed of a flexible heel encasing part closed like a bag and a belt part that wraps around and fixes the ankle and instep while fixing the core part to the heel part. (Japanese Patent Application No. 107145/1982), however, as a result of repeated research, it was found that the orthosis according to the invention may cause problems in terms of comfort, tension adjustment, ease of wearing shoes, etc. This is thought to be mainly due to the shape of the heel encasing portion, which led to the present invention.

In other words, for ankle joint disorders typified by ski sprains,
In many cases, it is not necessary to preserve the heel in an encapsulated state;
This is because if the heel portion is also subjected to the tension generated by the belt portion being wound and fixed, the effect of preserving the affected area may be reduced as a result. The present invention is revolutionary in that it eliminates these drawbacks due to the presence of the window.

"Flexible braces" refers to braces that do not use metal or are fixed in a cast, and are mainly made of cloth or other materials.

The "window" is an opening for partially exposing the heel.

The "heel enveloping part" refers to a part that envelops the heel, and is a part corresponding to the periphery of the window part. It also serves as a support when winding and fixing the belt while applying tension.

"Wrapping fixation" literally means fixing a suitable part of the ankle joint by stirring, but the fixation method is not limited and can be adjusted depending on the injury location, degree of injury, and injury details. It can be wrapped as appropriate, and this is one of the features of the brace of the present invention.

(e) Examples The present invention will be described in more detail below based on examples shown in the drawings.

FIG. 1 shows an example of an ankle orthosis (1) (hereinafter simply referred to as an orthosis (11)) according to the present invention.

As is clear from the figure, the orthosis (11 is the four belt parts (
2)...The convergence of these four belt parts (2) forms a heel-wrapping part (3) that wraps around the heel when worn. However, rather than completely covering the heel, a portion of the heel is exposed due to the presence of the window (5) provided near the center of the heel encasement (3). At the free end of each belt section (2) there is a hook-and-loop fastener (4).
is provided. The material is the hook-and-loop fastener (4
Vyrene:
U, S, manufactured by Rubber Co., Ltd.) were used. Although this alone showed a sufficient effect, it is also possible to construct a multilayer structure in which the bilene is used as the outer material and further provided with a lining material. In that case, the lining material is, for example, Opelon:
(manufactured by Toyo Products) etc. can be suitably used. Both of these materials are classified as polyurethane-based elastic fibers, and are well suited to the properties of braces (1), which apply appropriate pressure to the affected area by applying tension and wrapping and fixing. However, it is of course possible to use other materials.

FIG. 2 is an exploded view of the appliance (1) shown in FIG. 1. The brace (L) is roughly obtained by sewing together four belts. The sutures are made by suturing two belts at a time so that the included angle is about 150 degrees [sewn points (A) and (A)), and then suturing the sewn belt so that the overall shape is X-shaped. [Suturing location (B)] In this case, a heel encasing part (3) is naturally obtained, but as far as the inventor has made the prototype, it is better to partially overlap stitches (sewn part (B)) as shown in the figure. The shape of the joining part (3) closely followed the heel of the foot, making it easy to wind the belt, and providing a good feeling of wearing. Note that the window portion (5) may be cut out after the four belts are sewn together, or the shape of the belt may be changed in advance so that the window portion appears during stitching. (In the illustrated example, one vertex of the belt is cut out in advance.) Next, Figure 3 (al, (bl, and (C) shows an example of how to use the brace (1) shown in Figure 1. (As mentioned above, the orthosis according to the present invention is versatile and can be applied to various conditions such as damage to the medial and lateral ligaments and damage to the soil base, and cannot be used for a fixed purpose.) There is no method) First, bring the inner surface of the heel encasing part (3) into contact with the heel (hl),
The four belt parts (2)... can be pulled toward the front of the foot (see figure (a)). At this time, from the window (5) to the heel (
Part of h) will be exposed. Next, place the two upper belt parts (2) and (2) on your ankles. At this time, the window (5) becomes somewhat larger due to the tension of the belt, so this must be taken into consideration when determining the size of the window (5).

Then, place the two lower belt parts (2) and (2) on the instep of the foot ((C) in the same figure). Belt part raised in this way (2)
Various symptoms can be dealt with by adjusting the tension and the direction of hitting. Actually, 3 of LM-3
Since it seems that most individual differences can be covered by size,
For example, it can be said that it is an equipment that is easy to keep at all times in sports facilities and the like.

In most cases, the state shown in Figure 4 (C1) shows a sufficient effect of holding and fixing the affected area, but if reinforcement is required, a separate hook-and-loop fastener band (6) is used as shown in Figure 4.
) and (6) together is also an effective method.

It is preferable that the shape and elasticity of the surface fastener band (6) are taken into consideration in consideration of reinforcing force and fit. That is, if strong reinforcement is desired, a non-stretchable material is preferable, and if a comfortable wearing experience is desired, rather than strong reinforcement, a stretchable material should be used. The one used and illustrated by the present inventor is two slightly stretchable rectangular pieces with a width of 25 mm, but the number of pieces to be used and their shape should be considered on a case-by-case basis depending on the symptoms and other factors. It is. Furthermore, it is thought that the uses of the present invention product will be further expanded if a tape-like material is provided as an accessory member of the present invention device and the tape is cut to an appropriate length at the discretion of the user. Of course, the use of this hook-and-loop fastener band (6) is not an essential element of the invention.

Although the explanation has been made so far assuming that the number of belts is four, the present invention is not limited to this, and it is also possible to use two or three belts.

The point is, as shown in Figure 3 (a), the heel encasing part (3) (a part of the heel) is the part that supports the belt part (2) when it is wound and fixed while applying tension. (requires the presence of an open window to expose the
For example, as shown in FIG. 5, the number of belt portions (2) may be two.

In addition, in cases where the fixing force is insufficient when fixing with only the belt part (2), instead of using the above-mentioned hook-and-loop fastener band 6) after attaching the brace, you can attach something like cardboard to the belt in advance. Another method is to use it as a splint by sandwiching it between part (2) and the skin. (Not shown) (f) Effects of the invention As explained in detail above, the ankle orthosis according to the present invention has the following effects:
Consists of a heel encasing part made of a flexible material that has a window opening to expose a part of the heel, and a belt part that wraps around and fixes the ankle and instep while fixing the core part to the heel part. This orthosis is characterized by being lightweight and does not use hard materials such as metal members, so there is little discomfort when wearing it, and it feels very comfortable to wear. It can be used to treat a variety of conditions depending on the winding method, such as adjusting the tension, and since it does not require special techniques unlike taping, it is easy to use, and its versatility reduces the number of ready-made products. Therefore, it can be provided at a low price.
Furthermore, the presence of the window has the following advantages: it provides a better fit, improves the ability to support and fix the transverse tarsal joint, and makes it easier to wear regular footwear. This is an advanced invention.
