Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a correction supporter for correcting hallux valgus.
[0002]
[Prior art]
As shown in FIG. 4, the hallux valgus refers to a state where the heel is bent toward the second heel, and is said to be caused by forcibly walking with a shoe having a high heel and a pointed tip. Looking at the internal skeleton of the hallux valgus, as shown in FIG. 5, (1) the toe 1 is valgus, (2) thickening of the head of the first metatarsal bone, (3) lateral metastasis of the seed bone 3, 4 A phenomenon of varus of the first metatarsal bone 2 occurs. In this state, the center of gravity does not fall to the correct position (between the first metatarsal bone and the second metatarsal bone), and if left unattended, it will eventually strain the knee and may trigger knee pain. It has been.
[0003]
As a method of correcting hallux valgus in so-called brace therapy, an external force directed toward the varus direction is applied to the hallux, and an external force directed toward the valgus direction is applied to the first metatarsal bone. Has been.
For example, in Japanese Utility Model Laid-Open No. 60-71213, a band body made of a stretchable cloth and having a substantially frustoconical shape and a distal end extended obliquely from the large-diameter base edge of the band body An ankle joint holding band comprising a band-shaped fixing belt having a portion is described.
[0004]
In Japanese Utility Model Laid-Open No. 60-144414, one end of each of two stretchable belts is fixed to a bag portion covered with a mother's heel, and one belt winds an ankle across an instep diagonally. There is described a hallux valgus orthosis that is fixed to the instep of the belt with a hook-and-loop fastener and the other belt is wound from the sole to the instep and fixed to the one belt with the hook-and-loop fastener at the ankle.
Further, Japanese Patent Publication No. 2-12094 discloses a joint fixing band having a width and a length capable of covering and covering the entire first middle toe joint portion of a toe, and a bag shape connected to the joint fixing band. And a tension band with one end fixed to the outer side surface of the thumb container. The thumb is placed in the thumb container, the joint fixing band is wound around the foot, and the tension band is attached to the heel. There is described a supporter for correcting hallux valgus which is turned forward and then fixed to the band for joint fixation.
[0005]
[Problems to be solved by the invention]
By the way, the first metatarsal head is round and the bone is easy to move at the joint. Therefore, when the toe is evacuated due to pressure, the first metatarsal is varusally reversed and tries to remove the pressure. Therefore, in the hallux valgus, as shown by the arrows in FIGS. 4 and 5, the hallux of the first metatarsal occurs simultaneously with the hallux valgus. At the same time, a clockwise twist occurs in the mother's heel, and a counterclockwise twist occurs in the first metatarsal bone (both in the case of the right foot, both in the left foot are symmetrical).
[0006]
Therefore, in order to correct the hallux valgus and return the heel and the first metatarsal bone to the correct positions, simply apply an external force in the varus direction to the toe and apply an external force in the valgus direction to the first metatarsal. Instead, it is necessary to apply an external force to correct this twist at the same time. However, none of the conventional examples focus on the twist in the hallux valgus, and do not have a sufficient function as a device for correcting the hallux valgus. Specifically, the ankle joint holder disclosed in Japanese Utility Model Laid-Open No. 60-71213 does not have a force to cause the hallux varus, does not have the ability to correct the twist, and is difficult to correct the hallux valgus, and Japanese Utility Model Laid-Open No. 60-144414. The hallux valgus orthosis and the joint fixing band disclosed in Japanese Examined Patent Publication No. 2-12094 only have a function of pushing the heel 1 in the varus direction and pushing the first metatarsal 2 in the valgus direction.
[0007]
The present invention has been made in view of such problems of the prior art, and applies an external force directed in the varus direction to the toe and an external force directed in the valgus direction to the first metatarsal bone. It is an object of the present invention to provide a supporter for hallux valgus correction that can apply an external force for correcting the twist to the mother toe and the first metatarsal bone.
[0008]
[Means for Solving the Problems]
The hallux valgus correction supporter according to the present invention covers the entire first middle toe joint part of the toe and is attached around the sole and instep, and the toe attached around the toe. The mounting portion is attached by connecting the second heel side of the main heel mounting portion and the first heel side of the joint portion mounting portion obliquely, and a tensile force is applied between the two , and the heel and the first middle foot It is characterized by comprising a connecting belt that applies an external force to correct the twist on the bone . The hallux valgus correction supporter according to the present invention covers the entire first toe joint part of the toe and is attached around the sole and the instep, and around the toe. From a single connecting belt that is mounted by connecting the second heel side of the main heel mounting portion and the first heel side of the joint mounting portion obliquely and applying a tensile force between them. The connecting belt is characterized in that it passes from the second heel side of the thumb mounting portion to the side of the heel and reaches the first metatarsal side of the first metatarsal joint.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
As a specific form of this, the joint part mounting part is a joint part mounting belt that covers the entire first toe joint part of the toes and is wound around the sole and instep, The hull mounting part is cylindrical, and a hull is inserted here.
As a more specific form, the joint mounting part is a joint mounting belt that covers the entire first toe joint part of the toes and is wound around the sole and instep, The joint portion is connected to the front of the joint portion mounting belt to form a cylinder, the connecting belt extends from the main shaft mounting portion, and the joint portion mounting belt and the connecting belt are provided with a detachable mounting fastener.
[0010]
In this supporter, it is preferable that any of the joint portion mounting portion, the buckle mounting portion, and the connecting belt has some elasticity.
In addition, in order to add a twist between the mother toe and the first metatarsal bone, it is preferable that the inner surface side of the mother toe mounting part and the joint part mounting part is made of a material that is not slippery with respect to the skin. For this purpose, it is preferable to have air permeability. Examples of the material that hardly slips against the skin include well-known materials such as a material in which neoprene rubber is stretched, a urethane film, and a urethane resin foam. Urethane resin foams also have the advantage of good breathability.
[0011]
Hereinafter, the supporter for hallux valgus correction according to the present invention will be described in more detail with reference to FIGS. In addition, the example shown here is a supporter formed essentially from a single material, FIG. 1 is a diagram showing a mounting state of the supporter, and FIGS. 2 and 3 are bent joint mounting belts approximately in half. It is a figure which shows a state and the state extended.
[0012]
This supporter includes a joint mounting belt 4 having a width that covers the entire first middle toe joint of the toe, and a length that is wound around the sole and instep, and the front of the joint mounting belt 4. A cylindrical hull mounting part 5 connected to the hull, a second hull side (arrow a) extending from the hail mounting part 5 and a first hush side (arrow b) of the joint mounting belt 1 It is composed of a connecting belt 6 that is attached obliquely and applies a tensile force between them. Also, hook-and-loop fasteners 7 and 8 are attached to one end of the joint portion mounting belt 4 and the leading end of the connecting belt 6 for detachably fixing them when mounted.
[0013]
The material of this supporter is made of a urethane resin foam on one side, and the other side is made of a fastener material that can be fixed in a pair with the surface fasteners 7 and 8, with the urethane resin foam side on the inside. On the side, the main body mounting portion 5 is sewn in a cylindrical shape (sewn portion 9). In addition, it is good for the main body mounting | wearing part 5 to be made into the cylinder shape of the grade which lightly tightens the main body.
[0014]
When installing, insert the main hook into the cylindrical main hook mounting section 6 so that the sewing part 9 is on the second hook side (arrow a), and connect one side 4a of the joint mounting belt 4 to the first middle. The torso is wound around the toe through the sole of the toe joint and slightly pulled around the instep, and is wound around the instep with the other side 4b pulled slightly, and fixed to the surface on the one side by the hook-and-loop fastener 7. Next, the connecting belt 6 is pulled obliquely rearward, and is fixed to the surface on the first heel side (arrow b) of the joint portion mounting belt 4 that covers the first middle toe joint portion by the hook-and-loop fastener 8. At this time, the fixing portion by the hook-and-loop fastener extends from the center of the first metatarsal joint and comes to the first metatarsal side.
[0015]
By doing so, as shown by an arrow A in FIG. 1, a force that presses in the valgus direction acts on the first metatarsal joint, and an external force that corrects in the valgus direction is applied to the first metatarsal bone. In addition, as shown by the arrow B, an oblique pulling force acts between the main body mounting portion 5 and the joint portion mounting belt 4, and an external force is applied to the main body in the varus direction, and at the same time, An external force that corrects the twist is applied to the first metatarsal bone (twist is applied to the mother toe and the first metatarsal bone with the joint belt 6 sandwiching the joint portion).
[0016]
In addition, the supporter for hallux valgus correction according to the present invention is not limited to the above example, and can be variously modified within the scope of the claims. For example, in the above example, the joint attachment belt and the main body attachment portion are connected to each other. However, as long as a tension can be applied obliquely by the connection belt, this may be configured as a separate body. It is also possible to configure the three parts of the part mounting belt, the hull mounting part and the connecting belt as separate bodies. Furthermore, although the main body mounting portion is formed by sewing in a cylindrical shape, it may be formed into a cylindrical shape at the time of mounting with, for example, a hook-and-loop fastener. Furthermore, instead of the joint portion mounting belt fixed by the hook-and-loop fastener, a joint portion mounting portion formed in a cylindrical shape from the beginning can be used.
[0017]
【The invention's effect】
According to the supporter of the present invention, an external force directed in the varus direction is applied to the main heel, an external force directed in the valgus direction is applied to the first metatarsal bone, and at the same time, twist is corrected in the heel and the first metatarsal bone. Because it can apply external force, it is highly effective in correcting hallux valgus.
