Description
Technical field
This utility model relates to medical rectification device, is specifically related to a kind of anti-plantar flexion dynamic ankle-foot orthosis.
Background technology
Ankle-foot orthosis, also known as making shank orthosis, is the structure had from shank to vola, to the orthosis that ankle motion controls, can be divided into lattice framing formula ankle-foot orthosis, plastic ankle-foot orthosis, PTBankle-foot orthosis etc.Dorsiflexion is in medical field, and refer to and toe is lifted, instep is drawn close to facies anterior cruris, and the scope of normal ankle joint dorsiflexion is 20 to 30 degree, and popular saying is exactly that foot up hooks.Relative with dorsiflexion is plantar flexion, and refer to that toe is sagging, instep is away from shank.Traditional ankle-foot orthosis is fixing, and during use, shank and foot can not relative motioies, walking disorder; Someone proposed the orthosis that a kind of foot and calf can be movable afterwards, and foot can free dorsiflexion or plantar flexion to a certain extent, and walking is convenient.But some patients orthopedic time, such as hemiplegia, after the nerve injury such as paraplegia, can only allow its dorsiflexion and not allow its plantar flexion, to correct ankle joint deformity, turns up in foot, and drop foot, assisting patients stands walking, improves the abnormal gait of patient.At present, also do not have a kind ofly can allow dorsiflexion and the ankle-foot orthosis of plantar flexion can be prevented.
Utility model content
For solving above technical problem, this utility model provides a kind of and can allow dorsiflexion and can prevent the dynamic ankle-foot orthosis of plantar flexion.
Technical scheme is as follows:
A kind of anti-plantar flexion dynamic ankle-foot orthosis, the shank fixing head comprising sufficient supporting plate and be connected with this sufficient supporting plate, its key is: described shank fixing head structure in the form of slot, the notch of described shank fixing head toward the front, two cell walls of described shank fixing head are respectively to downward-extension and form fixing head journal stirrup, the ankle backplate that described sufficient supporting plate comprises foot plate and arranges around the heel portion of this foot plate, this ankle backplate structure in the form of slot, the cavity of described shank fixing head is positioned at directly over the cavity of described ankle backplate, described shank fixing head is positioned at inside described ankle backplate, described fixing head journal stirrup is hinged respectively by the cell wall that ankle rotating shaft is corresponding with described ankle backplate, after described shank fixing head and described ankle backplate push against, prevent plantar flexion.
Adopt the remarkable result of above technical scheme to be that the shank fixing head of channel-shaped is used for holding shank, foot plate is used at the bottom of supporting foot, and ankle backplate is used for around heel position; The fixing head journal stirrup that shank fixing head extends to form and ankle backplate hinged after, shank fixing head and sufficient supporting plate can rotate mutually at the ankle position of people, simulation ankle joint motion; In the process of tiptoe away from shank, because shank fixing head is positioned at inside described ankle backplate, shank fixing head can push against with ankle backplate, and shank fixing head and sufficient supporting plate can not continue to relatively rotate again, thus prevent foot plantar flexion.
In order to better realize this utility model, may further be:
The top edge of above-mentioned ankle backplate stretches out and forms anti-plantar flexion support portion, and the lower limb of described shank fixing head and described anti-plantar flexion support portion push against and prevent plantar flexion.Adopt above technical scheme, anti-plantar flexion support portion is for supporting the lower limb of shank fixing head, and support effect is good, more effectively can prevent plantar flexion.
Correspondingly on the described anti-plantar flexion support portion contacted with above-mentioned shank fixing head lower limb be provided with limited impression, when described shank fixing head goes to rearmost position, the lower limb of described shank fixing head falls in described limited impression.Adopt above technical scheme, limited impression can effectively prevent shank fixing head from rocking, and keeps whole ankle-foot orthosis to stablize.
Above-mentioned ankle rotating shaft is provided with torsion spring, and this torsion spring makes described shank fixing head and ankle backplate self-return.Adopt above technical scheme, by arranging torsion spring, after dorsiflexion, shank fixing head and ankle backplate energy self-return, thus auxiliary ankle joint rotates.
Above-mentioned ankle backplate is provided with foot fixture.Adopt above technical scheme, foot fixture is used for fixing foot.
Above-mentioned shank fixing head is provided with shank holding device.Adopt above technical scheme, shank holding device is used for fixing shank.
The lower surface of above-mentioned foot plate is provided with rubber layer.Adopt above technical scheme, rubber layer can prevent foot plate from skidding.
Beneficial effect: adopt anti-plantar flexion dynamic ankle-foot orthosis of the present utility model, ankle part can be allowed from normal position dorsiflexion, convenient walking; Simultaneously ankle part can be prevented from normal position plantar flexion, be applicable to hemiplegia, after the nerve injury such as paraplegia, the rectification of ankle joint deformity, corrects in foot and turns up, drop foot, and assisting patients stands walking, improves the abnormal gait of patient.
