Description
Technical field
A kind of KAFO is the utility model is related to, particularly relates to a kind of KAFO orthopedic to ankle foot progress.
Background technology
KAFO itself is worn from patient sensuously to say, for apoplexy sequela patient, some people's drop foot, foot
Varus has been formed, and his heel is tended not to through the relevant position of traditional ankle-foot orthosis heel, but is pressed in KAFO
Rear wall on, so as to produce larger pressure in patient's heel, cause it is local it is red and swollen, become silted up blue or green, or even ulceration.Also some feet
Vertical, strephenopodia, can be at the position that the apophysis such as external malleolus, navicular bone go out when dressing traditional ankle-foot orthosis than more serious patient
Local card pressure, pain are caused, therefore patient's wearing compliance is poor.
From KAFO effect is worn, for the patient of cerebral apoplexy relatively early stage, Most patients affected limb function is still
In abirritation period, at this time the prevention effect for strephenopodia, drop foot is very crucial, and traditional ankle-foot orthosis is often
Ankle joint angle is fixed on 90 ° of angles, it is impossible to make corresponding adjustment, at this time such KAFO is not have prevention foot at all
It is sagging, strephenopodia effect；On the other hand, the patient formed for drop foot, strephenopodia, traditional KAFO is to ankle-joint
Do not have the traction action in dorsiflexion direction, on foot when need compensatory Ipsilateral leg is lifted into get Geng Gao, be still that toe and group are outer
Side first lands, and does not have the role of correcting to pathologic hemiplegic gait thus, therefore therapeutic effect is bad, and this is for tradition
The major defect of technology.
Utility model content
The utility model provides a kind of dynamic type ankle-foot orthosis, its object is to overcome above-mentioned the deficiencies in the prior art,
A kind of dynamic type ankle-foot orthosis is provided, realizes comfortable wearing, preferably correction drop foot, the double action of varus, and this
It is main purpose of the present utility model to be exactly.
