Abstract

The utility model relates to a medical corrective apparatuses, in particular to a hallux valgus appliance, which is characterized by comprising a flexural metatarsal plate and a flexural phalanx plate which are overlapped, wherein the shape of the phalanx plate is inosculated with the inner side of phalanx, and the shape of the metatarsal plate is inosculated with the inner side of metatarsal, and the cross joint of the metatarsal plate and the phalanx plate is provided with a rotation shaft which is movably connected, and a concave structure on the overlapping position of the metatarsal plate and the phalanx plate at the rotation shaft is inosculated with varus deformity of metatarsal for avoiding rubbing skin. The corrective appliance further comprises a soft pad which is arranged on the sides of the metatarsal plate and the phalanx plate, which are closed to skin, a rear bandage which is fixed on the back end of the metatarsal plate and a front bandage which is fixed on the front end of the phalanx plate. The hallux valgus corrective appliance has reasonable structure and convenient use, is suitable for patients to operate by self, can greatly improve the corrective effect of light or moderate hallux valgus, and enables patients with heavy hallux valgus to avoid the long-term plaster fixation after surgery. As the rotation shaft can be synchronously bent with metatarsophalangeal joint, the hallux valgus corrective appliance can not affect daily life of patients while correcting hallux valgus.

Description

The intoe appliance

Technical field

This utility model is to be used for the corrigent a kind of medical apparatus of orthopaedics intoe---intoe appliance.

Background technology

Intoe is the front foot common disease, and slight intoe is not had effect method except that massage, binder colligation, be unfavorable for the daily walking of patient behind existing minority intoe appliance or the wearing, or corrective force is not enough, influences therapeutic effect; In, the severe intoe is many based on operative treatment, but needs long-time plaster fixation after the operation, is unfavorable for patient's early functional exercise, influences surgical effect.In addition, existing intoe appliance patient can not be from the line operate correction deformity.

Summary of the invention

The purpose of this invention is to provide a kind of intoe appliance, to overcome the deficiency of prior art.

The technical solution adopted in the utility model is: the metatarsal plate and the phalanx plate that it is characterized in that including two superimposed curved shapes of staggered place, phalanx plate shape and phalanx inboard match, metatarsal plate shape and metatarsal inboard match, and the intervening portion place between metatarsal plate and phalanx plate is provided with a rotating shaft that flexibly connects, talipes varus matches to avoid skin friction to hinder in the concave structure at the metatarsal plate at this rotating shaft position and the superimposed place of phalanx plate and the head of metatarsal bone, the cushion of the skin side that is positioned at metatarsal plate and phalanx plate is arranged again, and the back band and the preceding band that is fixed in the phalanx front edge of board that are fixed in metatarsal plate rear end.

The cushion of above-mentioned nearly skin side at metatarsal plate and phalanx plate is the sponge cushion of thick 2mm, can make skin avoid friction.

This utility model is rational in infrastructure, and is easy to use, and suitable patient is from line operate, and improves the rectification effect of intoe greatly, makes the intoe postoperative patient not need long-time plaster fixation.When correcting intoe, do not influence the activity of bending and stretching of metatarsophalangeal joints again, also can not cause thumb capsule place skin abrasion, the movable rotation-shaft that is provided with between these two hardboards of metatarsal plate and phalanx plate helps the bending and stretching activity of metatarsophalangeal joints and does not influence patient's daily life.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 basic structure sketch map of the present utility model.

Fig. 2 this utility model is at the concrete use sketch map at foot big toe place.

Wherein, 1, preceding band 2, rotating shaft 3, back band 4, phalanx plate 5, metatarsal plate 6, cushion.

The specific embodiment

In Fig. 1, it is characterized in that having the metatarsal plate 5 and the phalanx plate 4 of staggered superimposed two curved shapes, phalanx plate 4 shapes and phalanx inboard match, metatarsal plate 5 shapes and metatarsal inboard match, and the staggered superimposed place between metatarsal plate 5 and phalanx plate 4 is provided with a rotating shaft 2 that flexibly connects, talipes varus matches to avoid skin friction to hinder in concave structure between the metatarsal plate 5 at this rotating shaft position and 4 phalanx plates and the head of metatarsal bone, the cushion 6 of the skin side that is positioned at metatarsal plate 5 and phalanx plate 4 is arranged again, and the back band 3 and the preceding band 1 that is fixed in phalanx plate 4 front ends that are fixed in metatarsal plate 5 rear ends.

In Fig. 2, phalanx plate 4 is positioned at the phalanx inboard, metatarsal plate 5 is positioned at the metatarsal inboard, rotating shaft 2 is positioned at the metatarsophalangeal joints inboard, preceding band 1 bundle is tied in big toe and far saves, back band 3 bundles are tied in the metatarsal position, have corrected the hallux valgus deformity by the metatarsal plate 5 and the phalanx plate 4 that link to each other, and the sole of the foot that does not influence metatarsophalangeal joints because rotating shaft 2 is analogous to Movable joint is bent and the back of the body is stretched.

This utility model utilizes metatarsal plate and phalanx plate difference fixing foot forward metatarsal position and big toe joint far away to correct the intoe deformity, severe intoe patient postoperative can ground be movable down in early days in making, and avoid long-time heavy plaster fixation, and the intoe patient can be from line operate, the movable rotation-shaft that is provided with between two hardboards of metatarsal plate and phalanx plate again helps the bending and stretching activity of metatarsophalangeal joints and does not influence patient's daily life.
