BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape bun which is attached to a foot and is used for correcting and preventing bunions.

2. Description of the Related Art With regard to hallux valgus, research is progressing in Europe and the United States rather than Japan, and many reports have been made regarding its pathological condition. With reference to them, the present inventor considered the pathological condition of hallux valgus as follows. The first cause of hallux valgus is
That is, when the load is applied, the entire toe including the toe 14 and the first metatarsal bone 15 (example of toe) is pronation (the anterior side of the toe faces the second toe). As a result, bending of the toes results in bending of the toes in the valgus direction. This is the early deformation of the hallux valgus. In short, in the early stage of hallux valgus, valgus of the hallux valgus occurs due to pronation of the hallux valgus. The valgus deformity and the pronation deformity of the toes are enhanced by the compression of the forefoot by wearing the shoes. However, this initial transformation is reversible and relieves at rest.
To make this initial deformation progress and make it irreversible,
It is a powerful force of the flexor flexor of the elbow. The flexor long toe muscle is a muscle that bends the big toe and has a powerful muscle strength that can support the weight of the big toe. The flexor longus flexor tendon 16a that is the tendon
Runs along the bottom side of the toes and reaches the tip of the toes.
Even when the ball of the big toe is pronation and the toe is valgus, the flexor tendon of the long toe is pulled by a great force and tries to run in a straight line. As a result, the flexor long toe flexor tendon runs outside the second toe (second toe side) 16b. Then, the flexor long flexor tendon acts like a chord of the bow, increasing the pronation and valgus of the ball of the toe, and at the same time, the first metatarsal 15 is varus (the tip is the second medial). Bending so that it can be released from the foot bone, and bending the joint 17a (first metatarsal interphalangeal interphalangeal joint) 17a in between to the inside 17b. The positions of other muscles and tendons around the toes also change with the long toe flexor tendon, thus failing to function normally. Further, two bean-like small bones (seed bones) 18a on the bottom side of the first metatarsal interphalangeal joint also move to the outside together with the flexor pollicis longus muscle, and these may be dislocated to the outside 18b. . A vicious cycle is repeated with the progress of these deformities and the action of the bowstring of the flexor longus tendon, and the deformity of the hallux valgus becomes progressive and becomes irreversible. On the other hand, patients with hallux valgus,
I feel that focusing on the flexor longus muscles can potentially exacerbate the symptoms of hallux valgus. Therefore, a patient with hallux valgus has an unnatural gait that does not put force on the flexor longus flexor muscles and does not put weight on the toes. This unnatural way of walking adversely affects other parts of the foot, such as the knees and hips. The above is the condition of hallux valgus. Conventionally, a large number of orthoses, supporters, and adhesive tapes have been produced and devised for the purpose of correcting and preventing bunions. However, these are all aimed at correcting the apparent deformity of the hallux valgus, such as valgus valgus and inward protrusion of the first metatarsal interphalangeal joint, and in the hallux valgus, The pronation of the toes and the effects of the flexor longus flexor tendon are not considered. We believe that these conventional methods make it difficult to radically correct bunions. In addition, the conventional one is bulky, so it is especially suitable for wearing shoes, especially shoes such as high heels where the forefoot is narrow.
There were many obstacles. Even if the shoes are designed so that they do not interfere with the wearing of shoes, most of them basically try to correct the hallux valgus by widening the space between the toes and the toes, so that the front legs such as high heels should be used. The effect was completely lost when wearing the narrowed shoes.

[0003]

DISCLOSURE OF INVENTION Problems to be Solved by the Invention To correct the hallux valgus, the present inventor first corrects the position of the flexor malleolar flexor tendon to return it to the original position. We considered it important to correct varus deformity. By these corrections, the position of the flexor longus flexor tendon 17b becomes close to the normal position, and
The action of the bowstring of 7b is mitigated, conversely its great force is directed to correct the deformity of the hallux valgus. The valgus of the toe and the inward protrusion of the first metatarsal interphalangeal joint are corrected,
The position of the seed bone is also corrected. In this way, by restoring the positional relationship between the toe row and the flexor long toe muscle tendon, the deformation of the hallux valgus is fundamentally corrected. However, there are two issues here. The first is the pronation of the hallux valgus, and the varus deformity of the first metatarsal bone, which is reinforced by the powerful force of the flexor hallucis longus. Correcting the varus deformity of the foot bone requires a force that opposes the great force of the flexor longus muscle. The other is continuous proversion of the hallux valgus and varus valgus of the first metatarsal during standing load when the great force of the flexor hallucis longus acts and when wearing shoes that worsen the hallux valgus deformity. Deformation correction is necessary.

[0004]

In order to solve the above-mentioned problems, the present invention provides a space between the back of the toes 6 and the toes 7 between the toes and the toes.
The bottom side 8 of the first metatarsal interphalangeal joint, below the protrusion 9 of the first metatarsal interphalangeal joint, the inner side 10 of the first metatarsal bone, the dorsal part 11 of the foot, and the lateral ankle 12 The lower ankle 12 through the lower part of the
Has a length to be attached from a rear part of the toe to a rear part of the heel 13 and has a width enough to cover a part proximal to the dorsal nail of the big toe 6, and a distance between the big toe and the toe 7 The width of the portion 2 passing through is narrow, and the attachment surface of the portion 1 to be attached to the back side of the toe 6 and the attachment surface of the portion 4 to be attached to the rear of the heel 12 to the rear of the heel 13 have adhesiveness. A tape bun for hallux valgus correction and prevention is provided in which the mounting surface of the portion 3 to be mounted on the back of the foot 11 is covered with a non-adhesive material that does not irritate the skin.

[0005]

According to the present invention, by taking the above-described method, the greater toe flexor muscle force is overcome and the greater toe 14 is supinated, and the first metatarsal bone 15 is valgus and the first metatarsal is displaced. It has the effect of bringing the bone closer to the second metatarsal bone.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments shown in the drawings will be described in more detail below. FIG. 1 is a plan view of an embodiment of the present invention, and FIGS. 2 and 3 are a plan view and a perspective view showing a state in which the embodiment is mounted on a foot. Reference numeral 1 denotes a portion having adhesiveness to the mounting surface, which is fixed to a portion proximal to the nail on the back side of the toe 6 of the toe. Two
Is a portion having a narrow width which is attached from the inside of the toe 6 to the toe 7 between the toe and the toe. Reference numeral 3 denotes a portion which is attached to the back of the foot 11 and whose attachment surface is covered with a non-adhesive material that does not irritate the skin. Reference numeral 4 is a portion having adhesiveness to the mounting surface, which is fixed from the rear of the outer heel 12 to the rear of the heel 13.

When the present invention is used, first, the first portion is fixed to the back side of the toe, and while pulling so that the toe is supination, the second portion is passed between the toe and the toe 7 through the foot. Bring to the inside 10 of the first metatarsal while pulling the protrusion 9 of the first metatarsal interphalangeal joint from below to rotate it to the bottom, and bring the first metatarsal 18 to the second middle metatarsal. The part 3 is attached to the dorsal part 11 of the foot while pulling it so that it approaches the foot bone, and the part 4 is fixed to the part from the rear of the outer heel 12 to the rear of the heel 13.

The present invention is fixed to the back side of the toe 6 and the toe 6
It is attached so as to wrap around. As a result, a force is added to the supination of the toes. Next, between the mother's toes and the toes 7
From the lower part of the protrusion 9 of the first metatarsal interphalangeal joint,
While applying a force to push the protrusion 9 from the bottom side to the back side,
The dorsal 11 of the foot is reached via the medial side 10 of the first metatarsal bone. After that, by passing under the outer ankle 12 and being fixed to the rear of the heel 13, a force is applied so that the first metatarsal bone 18 is valgus and approaches the second metatarsal bone.

The action of supination of the toe 14 and valgus of the first metatarsal bone 15 of the present invention has the function of basal phalangeal joint 18 of the first metatarsal bone.
When dorsiflexed, it is enhanced, and when it is planted, it is diminished. Therefore, when the first toe metaphyseal interphalangeal joint 18 is dorsiflexed due to weight on the big toe during walking, that is, when a great force is applied to the flexor long toe flexor tendon, the action of the present invention Is enhanced.

The portion 2 passing through the space 7 between the toe and the toes of the present invention
The narrow width of the not only reduces the discomfort between the toe 7 of the toe and the toe when it is worn, but also prevents the tape from curling around the area and becoming hard, which prevents it from getting into the skin. .

The skin around the back of the foot 11 is weak against irritation and is liable to cause rashes and dermatitis. In the present invention, the part 3 attached to that part is made of a material that is non-adhesive and has little irritation to the skin. Since it is covered, damage to the skin due to wearing is reduced.

【The invention's effect】

1) The present invention is a force that overcomes the force of the flexor toe of the long toe.
The pronation deformation of No. 4 is corrected, the varus deformation of the first metatarsal bone 15 is corrected, and the first metatarsal bone 15 is brought closer to the second metatarsal bone. As a result, the positional relationship between the flexor long toe muscle 16b and the toe rows 14 and 15 is close to normal, and the action of the bowstring of the flexor long toe muscle 16b is reduced, so that the hallux valgus of the toe is reduced. The inward protrusion of the first metatarsal interphalangeal joint 17b is corrected, and the seed bone 1
The position of 8b is reduced, and the deformation of the hallux valgus is fundamentally corrected. Further, the present invention is effective not only for correcting the deformity of hallux valgus, but also for preventing the deterioration of hallux valgus deformity and preventing the hallux valgus.

2) By wearing the present invention, the patient naturally feels that the valgus hallux valgus symptom does not worsen even if force is applied to the flexor hallucis longus, and the patient naturally puts strength in the flexor longus. Start walking with weight on the toes.

3) Since the present invention hardly limits the movement of the toes, it does not interfere with activities such as labor and sports. Also, since it is not bulky, it does not interfere with wearing shoes. In particular, according to the present invention, since the second fixing portion 2 that passes between the toes of the mother's toe and the toes is thin, it is difficult to wear shoes such as high heels where the forefoot is narrow and the toes are pressed. I don't.

4) Since the present invention does not attempt to correct the hallux valgus by widening the space between the toes and the toes, even when wearing shoes such as high heels having a narrow forefoot, the effect is completely absent. Not lost

5) According to the present invention, the skin around the back of the foot, which is vulnerable to irritation, is unlikely to be damaged, so that continuous wearing can be easily performed.

6) Since the present invention is a single use, it is easy to carry and wear.
