Description

  The present invention relates to an improvement of a correction tool for correcting a hallux valgus in which a heel (thumb) is bent in the direction of a second heel.

As described in Patent Document 1 below, the present inventor comprises a supporter formed of a stretchable cloth, a mother sack, and a traction band having one end fixed to the heel sack. A device for correcting hallux valgus was devised. According to the literature 1, the supporter (for the right foot) is composed of a hook part provided with a hook hole, a left wing part and a right wing part extending left and right from the hook part, and a hook-and-loop fastener that adheres to both wing parts ( A female fastener and a male are attached, and a hook-and-loop fastener (male) is attached to the other end of the traction band. In mounting the hallux valgus correction tool, first, the supporter is wound around the root part (right foot), and the double-sided fastener is attached on the instep side to attach to the foot part. Cover the heel, pull the traction band so that it comes to the side (inner side) without the traction band, and bond the hook-and-loop fastener to the hook-and-loop fastener on the left wing side. Thus, the hallux valgus is gradually corrected by continuing to mount the tension of the traction band in the direction (inner side) in which there is no wrinkle (direction to return to normal).
In addition, there are those described in Patent Documents 2 to 7 below as correction tools for correcting hallux valgus by applying an external force directed in the direction of inward (inward) wrinkles.

Registered Utility Model No. 3059927 Registered Utility Model No. 30080252 Registered Utility Model No. 3092122 Japanese Patent Laid-Open No. 11-76283 JP 2000-116696 A JP 2000-116686 A JP 2003-290263 A

  The correction tool described in Patent Document 1 has the advantage that it does not give pain or pressure to the foot and can be worn without difficulty for a long period of time, and as a result, it can effectively correct hallux valgus. . However, in the case of this correction tool, particularly when the hallux valgus is largely deformed, as shown in FIG. 5, the heel sack 2 rotates during use to fix the traction band 3 (see the arrow position in FIG. 5B). Therefore, there is a possibility that the traction band 3 is not directed in the direction (inward) in which the wrinkles are not drawn but is pulled upward. If it becomes like this, the effect of this correction tool will be lost.

In order to prevent this, the traction band 2 is affixed to the foot with adhesive tape in the vicinity of the fixing portion of the traction band 2 (see the arrow position in FIG. 5A) so that the heel sack 1 does not rotate. Although it was seen, a sufficient effect was not obtained.
The present invention has been made in view of such problems of the conventional orthodontic appliance, and prevents the heel sack from rotating during wearing, and the traction band loses the effect of directing the heel toward the inside. The purpose is to prevent it from being broken.

The present invention includes a supporter formed of a stretchable cloth, a heel sack, and a traction band having one end fixed to the heel sack, and the supporter is mounted around a foot portion. Then, a hook-and-loop fastener is attached to the surface (the inner side) where there is no hole, and the hook is exposed, and a hook-and-loop fastener that adheres to the hook-and-loop fastener of the supporter is attached to the back surface of the other end of the traction band, The present invention relates to an improvement of a hallux valgus correction tool in which a hook-and-loop fastener of a supporter and a hook-and-loop strap of a traction band are bonded to each other, and the traction band is pulled backward by the traction band. The main traction belt and the upper and lower auxiliary traction belts are three, and the surface fastener of the supporter has a vertical width substantially equal to or greater than the sum of the widths of the three traction belts. It is characterized by being set large.
As a specific form of the present invention, the supporter is detachably divided on the upper side, and one end of each of the three traction bands is fixed to the side (inner side) without the thumbstick. be able to. In addition, the side (inside) where there is no is the center side of the body.

  According to the correction tool of the present invention, even when the hallux valgus is severely deformed, the heel sack rotates during wearing, and the action of turning the traction band in the direction of the inner side of the heel is lost. It is prevented.

A hallux valgus correction tool (for the left foot) according to the present invention will be described with reference to FIGS. This orthodontic tool is composed of a supporter 11 and a heel sack 12 each formed of a stretchable cloth, and a traction band 13 to 15 (one main traction band 13 and an auxiliary traction) fixed at one end to the heel sack 12. Belt 14 and 15).
The supporter 11 is three-dimensionally configured to be mounted around the foot, and includes a main body 16 mounted on the heel and the periphery thereof, and a left wing portion 17 and a right wing portion that extend to the left and right and are connected on the back side. 18, and has a pit 19 in which the ridge is exposed at a substantially central portion of the main body portion 16. A hook-and-loop fastener (female) 21 is attached to an end portion of the left wing portion 17, and a hook-and-loop fastener (male) 22 is attached to an end portion of the right wing portion 18, and the double-sided fasteners 21 and 22 can be bonded to each other. Therefore, it can also be said that this supporter 11 is detachably divided on the back side. When the double-sided fasteners 21 and 22 are bonded, the supporter 11 is formed with a cylindrical portion 23 that surrounds the ankle and a cylindrical portion 24 that surrounds the foot, and these cover the periphery of the foot portion.
Further, a surface fastener (female) 25 having a relatively large area is attached to the surface of the supporter 11, and this surface fastener is positioned on the side of the inner side that is not present when the supporter 11 is mounted. It is attached to the supporter 11 (see FIGS. 3 and 4).

  The saddle sack 12 has a size that accommodates most of the length of the heel, and one end of three traction bands 13 to 15 is fixed to the inner surface of the heel sack 12. The central main traction band 13 is wide, and the left and right auxiliary traction bands 14, 15 are each half the width of the main traction band 13, with the main traction band 13 on the inside and the auxiliary traction bands 14, 15 on the outside. It is fixed so as to overlap. Surface fasteners (male) 26 to 28 are attached to the back surfaces of the other ends of the main traction belt 13 and the auxiliary traction belts 14 and 15, and these can be bonded to the surface fastener 25. Note that the vertical width W of the hook-and-loop fastener 25 (the vertical width when mounted; see FIG. 1) is set wider than the sum of the widths w1, w2, and w3 (see FIG. 2) of the hook-and-loop fasteners 26 to 28. ing.

In mounting this corrector, as shown in FIGS. 3 and 4, first, the supporter 11 is mounted around the foot portion. At this time, the hook is applied to the hook hole 19 so that it comes to the side (inner side) where the hook-and-loop fastener 25 is not provided, and the hook-and-loop fastener 22 is attached to the hook-and-loop fastener 21 on the upper side. At this time, the stability of the mounted supporter 11 is increased by exposing the ridge from the pit hole 19.
Next, as shown in FIGS. 3 and 4, the heel sack 12 is fitted to the heel so that the main traction belt 13 and the auxiliary traction belts 14 and 15 are not present (inner side). Is pulled to attach the hook-and-loop fastener 16 to the hook-and-loop fastener 25, and then the auxiliary traction bands 14 and 15 are pulled to attach the hook-and-loop fasteners 27 and 28 to the upper and lower positions of the hook-and-loop fastener 26 of the main traction band 13. In addition, since the vertical width W of the hook_and_loop | surface fastener 25 is set larger than the sum total of the width | variety of the hook_and_loop | surface fasteners 26-28, such affixing is possible.

  As a result, the saddle sack 12 is pulled rearward by the main traction belt 13 and the auxiliary traction belts 14 and 15, so that an action of turning the heel sack inward (inward) direction occurs. In addition, since the auxiliary traction bands 14 and 15 extend obliquely with respect to the main traction band 13 that extends rearward substantially horizontally, the tension has a component that pulls the heel sack 12 in the vertical direction, and on the inner side. Since the protruding first intermediate foot joint indirect portion is sandwiched from above and below, even when the position of the heel sack 12 is stable and the hallux valgus is greatly deformed, the fixing portions of the traction bands 13 to 15 are in use. Is prevented from rotating upward.

  Other than that, it is almost the same as the correction tool described in Patent Document 1. That is, the supporter 11, the heel sack 12, and the traction bands 13 to 15 are made of stretchable cloth, for example, girdle fabric such as rubber knitted or knitted jersey. Moreover, as long as the hook_and_loop | surface fastener 21 and the hook_and_loop | surface fastener 22 mutually adhere | attach, any may be female and any may be male. The relationship between the hook-and-loop fastener 25 and the hook-and-loop fasteners 26 to 28 is the same. Further, the right foot correction tool is formed symmetrically with the left foot correction tool.

It is a perspective view of the supporter of the correction tool which concerns on this invention. It is a perspective view of the heel sack and traction band of the correction tool. It is a front side perspective view when wearing the correction tool concerning the present invention. It is a side view similarly. It is a top view for demonstrating the problem of the conventional correction tool.
