Description

  The present invention relates to a correction tool for correcting hallux valgus.

Many proposals and tools for correcting hallux valgus have been put to practical use. However, for example, all of them use a stretchable belt, etc. On the other hand, it is characterized in that a tensile force is applied so that an external force directed in the valgus direction can be applied.
In addition, with another specification, the other side of the lever with the warp that fixes the main hook to the tip is fixed to the foot, and the main hook is warped to the opposite side and fixed with the lever acting as a fulcrum Some are characterized by the following.

However, because the former material is a stretchable belt, etc., depending on the usage or procedure procedure, the required tensile force required for each part is not found to be insufficient or corrected. The effect tends to vary, and the latter mainly has a fixed state with both the joints of the mother's joint, and thus has a problem of lack of functionality as a device for correcting hallux valgus, showing the effect of so-called surgical therapy.

  As described above, a stretchable belt or the like used for applying a tensile force so as to apply an external force directed to the hallux valgus and the valgus direction to the first metatarsal bone is used or its procedure. Depending on the procedure, the required tensile force at each part is likely to be insufficient, and the correction effect cannot be expected. In view of the problem of the single function of the wood, the present invention applies an external force directed to the valgus to the first metatarsal via the bone head of the first metatarsal. The valgus correction can be applied to the tip by applying an external force directed in the varus direction without interfering with the joint function of the main heel, and further applying the necessary twist correction external force to the first metatarsal bone under various conditions of the shape of the bone head. It is in providing tools.

The present invention relates to an action bar attached by a belt along the side of the main shaft without interfering with the joint function of the main shaft, and a rotatable structure via a pin having the end portion of the action bar as a central axis. The left and right side plates are configured so that one lateral side position of the side plate abuts against the bone head of the first metatarsal, and the end of the connection part extends along the arch of the arch The main feature is that the lever function is configured to include a base bar that is integrally formed in a shape configuration and has a length of a base bar that is slightly lengthened so that it can be tightly bound by a belt on the side of the foot.
As a result, an external force is applied to the toe tip in the varus direction and the first metatarsal bone to the valgus direction, and at the same time, the external force enabling the twist correction required for the toe tip and the first metatarsal bone is also provided. Realized the purpose of being able to add.

  The hallux valgus correction tool of the present invention is different from the correction tool characterized by a supporter specification and a splint specification mainly comprising a flexible belt, etc., in the varus direction with respect to the tip of the heel, and on the first metatarsal bone. On the other hand, a direct acting force capable of applying an external force directed to the valgus direction is attached without disturbing the joint function of the main body, and the working bar is configured to be rotatable, and the first metatarsal The functional configuration by the lever action configured by the arch-shaped base bar that integrally configures the connecting portion having the bone head as a fulcrum position is highly effective as a hallux valgus correction tool.

  In the various conditions at the time of contact in the shape of the bone head of the first metatarsal, which is a disc shape, and the pivoting end portion of the action bar and the left and right side plates sandwiching the pivoting structure with a pivotable structure It is functionally configured so that the joint function of the toe is not hindered and an external force that corrects the twist can be applied simultaneously with the required external force applied to the toe and the first metatarsal bone. Being great is great.

  The side plate to be brought into contact with the bone head of the first metatarsal bone according to claim 3 is used as a cushion and functions without impairing a predetermined required action by preventing displacement in various conditions during the contact action. The provision of the pad in the shape of a suction cup is very excellent in the function maintaining configuration.

  Left and right sides that are structured to be pivotable via a working bar that is attached by a belt along the side of the main shaft without interfering with the joint function of the main shaft, and a pin having the end portion of the working bar as a central axis. A plate is formed, and the shape of the connecting portion is set so as to follow the arch of the arch from the end of the connecting portion with the lateral side position of one of the plates as a fulcrum position and contacting the bone head of the first metatarsal bone. An external force directly formed through the bone head of the first metatarsal, which has a lever function consisting of a base bar having a length so that it can be tightly bound by a belt on the lateral side of the foot. The purpose of providing a means for correcting hallux valgus by action was realized with a minimum of members.

FIG. 1 is an overall explanatory view showing a combination configuration of each main part of the device, and FIG. 2 is a configuration of an action bar 1 and a side plate 4 ′ in the main part of FIG. FIG. 3 is a partial side view showing the base bar 2, the pad 5, and the like integrally formed with the connecting portion 4, and FIG. 3 is an explanatory view showing the use state of the hallux valgus correction tool.
Hereinafter, it will be described in detail with reference to the drawings.

Symptoms of hallux valgus are, for example, when the toe of the toe is subjected to valgus due to external force or the like, the first metatarsal is varusally reversed via the bone head of the first metatarsal, and at the same time the first middle The rotation of the foot bone (twist) causes the seed bone to be displaced.
The hallux valgus correction tool of the present invention corrects the hallux valgus symptom and returns each to the correct position. Therefore, the valgus tip is applied to the tip of the heel and the valgus is applied to the first metatarsal bone. And a lever function that can also apply an external force to correct the twist in the first metatarsal bone.

The action bar 1 is a flat plate having a slight width and length and is made of a rigid material. The action bar 1 includes an action bar belt 1 ′ with a hook-and-loop fastener 8 to be attached to the main body 6, and one end of the connection bar 4. It is sandwiched between the left and right side plates 4 ′ and is configured to be rotatable with a pin 3 provided as a central axis.
At this time, both the rotating end portion of the action bar 1 and the left and right side plates 4 ′ sandwiching the rotating end portion via the pin 3 as a rotatable structure are formed into a disk shape, thereby allowing the bone head 7 of the first metatarsal bone 7. The function is configured so that the rotation function is not hindered in the pressure applied under various operating conditions with the fulcrum as the fulcrum position.

  The connecting plate 4 which has rigidity and constitutes the left and right side plates 4 'is arranged in a first position at a lateral position which is a fulcrum position on one side plate 4' which sandwiches the action bar 1 so as to be rotatable. By attaching a sucker-like pad 5 to be brought into contact with the bone head portion 7 of the foot bone, the first middle portion is used as a cushion in the bone head portion 7 of the first metatarsal bone and is a joint functional part of the first metatarsal bone. Using the bone head 7 of the foot bone as a fulcrum position, it is possible to prevent misalignment in various conditions related to the shape of the head, and to correct the twist simultaneously with the required external force applied to the tip of the first toe and the first metatarsal bone. The functional configuration is made so that an external force can be applied.

  And the hook-and-loop fastener is formed from the end of the connecting part 4 along the arch of the "arch" and attached along the side of the foot so that it can be tightly bound by winding around the sole and instep. A rigid base bar 2 having a length with a base bar belt 2 'with 8 is formed integrally.

  In this case, in use, the working bar belt 1 'with the hook and loop fastener 8 provided with the working bar 1 is attached along the lateral side of the main rod 6 without hindering the joint function of the main rod 6. The pad 5 provided on the side of the side plate 4 ′ of the connecting portion 4 is brought into contact with the bone head 7 of the first metatarsal bone, and the base bar 2 integrally formed with the connecting portion 4 follows the “arch” arch. In this way, the action bar 1 is brought into contact with the bone head 7 of the first metatarsal that constitutes the fulcrum by being brought into the tight state by the base bar belt 2 ′ with the hook-and-loop fastener 8. By pulling the main rod 6 through the action bar belt 1 'with the hook-and-loop fastener 8 with the lever-operating force applied to the arm, an external force is applied to the tip of the main rod 6 in the varus direction and the first metatarsal is used as a fulcrum. In the valgus direction via the bone head 7 of the first metatarsal that abuts The Ku external force, will also be added external force to correct the twist in the hallux 6 destination and metatarsal first simultaneously from femoral head shape and joint function conditions related thereto of the first metatarsal bone head 7.

At this time, the pivoting portion constituted by the end portion of the working bar 1 and the left and right side plates 4 ′ is distorted or twisted due to the load applied to the connecting portion 4 constituting the working bar 1 and the left and right side plates 4 ′. Each contact surface is formed in a disc shape so that the action is not hindered, and is configured by a rigid action bar 1 and a base bar 2 integrally formed with a connecting part 4 constituting left and right side plates 4. The rigid effect is such that the joint function required by the mother heel 6 is not hindered.
In addition, each functional configuration in the hallux valgus correction tool of the present invention is a brace therapy that can directly apply an appropriate external force without difficulty so that the pressurization condition that causes the hallux valgus symptom can be reversed. Although it is mainly made of rigid materials, it does not interfere with walking, etc., and does not cause external forces that cause pain to the feet. The functional structure is made.

  The hallux valgus orthodontic appliance is not only a hallux valgus symptom but also one of the effective methods that can be expected for conservative therapy in other surgical and orthopedic medicines, and its functionalities are not only for home use but also for various industrial uses. Application use can be expected.
