Back connection type portable ankle-foot orthosis

Technical Field

The utility model relates to an ankle sufficient orthopedic ware technical field, concretely relates to back connection formula lightweight ankle sufficient orthopedic ware.

Background

Ankle foot orthotics, which are generally used to provide protection to a patient's ankle and foot while providing support against excessive plantarflexion (colloquially referred to as "foot drop"), may be used to support, protect, correct or protect a patient's limb by exerting a force on the patient's limb to effect the correction. Plantarflexion is a medical condition caused by disease, trauma, or congenital abnormalities. Patients affected by this disease typically have difficulty walking because the patient's feet generally tend to droop when lifted off the ground, so to avoid tripping over, the patient typically must lift the foot higher than it should. The primary function of the ankle foot orthosis is to provide resistance to plantarflexion, helping to maintain the patient's foot in the correct position when the foot is raised above the ground.

When the existing ankle corrector is used, the ankle joint connecting devices of the orthopedic shoes are placed at the medial and lateral condyles on the two sides, which is more prominent and affects the appearance.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to overcome the above-mentioned defect that prior art exists, provide one kind and make shoes outward appearance more pleasing to the eye, be connected with a back connection formula lightweight ankle foot orthopedic ware that toughness and resistance are strong.

The utility model provides a technical scheme that its technical problem adopted is: a rear connection type portable ankle-foot orthosis comprises a shin back plate and a foot support which are arranged in a shoe body, wherein the bottom end of the shin back plate is connected with the top end of the rear part of the foot support through a rear connection device, shin bevel edges are arranged on two sides of the lower part of the shin back plate, and the shin bevel edges on the two sides enable the lower part of the shin back plate to be narrow; the heel of the foot support is provided with a heel bevel edge at two sides close to the heel part, the heel upper part of the foot support is narrow by the heel bevel edges at two sides, and a larger opening is formed between the shin bevel edge and the heel bevel edge at the same side.

Furthermore, the upper part of the shoe body is provided with a tensile cloth for preventing the rear connecting device from being excessively stretched.

Furthermore, the rear connecting device comprises an upper mounting seat, a lower mounting seat and a connecting block, the upper mounting seat is arranged at the bottom of the shin rear plate, the lower mounting seat is arranged at the upper part of the heel of the foot support, and the upper part and the lower part of the connecting block are respectively connected onto the upper mounting seat and the lower mounting seat through butt nuts.

Furthermore, the upper mounting seat and the lower mounting seat are both outwards convex.

Furthermore, the upper mounting seat and the shin backboard are integrally formed, and the lower mounting seat and the foot support are integrally formed.

Further, the connecting block is made of thermoplastic polyurethane elastomer rubber.

Further, the horizontal cross section of the tibia backboard is C-shaped, and the structure design can fix the lower leg of the patient from two sides and ensure the stability of the ankle-foot orthosis in use.

Furthermore, the longitudinal length of the foot support is longer than that of the feet of the patient, so that the support can be provided for the whole feet of the patient, and the condition of foot drop is prevented.

The beneficial effects of the utility model are that, connecting device has very strong toughness after it, adopts antifatigue special material to replace ankle joint's rotation, utilizes the support of connecting device after and the stretch resistance cloth control ankle joint of upper of a shoe bend, and both sides do not have connecting device, and shin back plate lower part is narrow for a short time, solves the outward appearance problem, makes shoes outward appearance more pleasing to the eye.

The ankle-foot orthosis has the functions of: 1. improving the stress state or load-free of the feet of the patient during standing and walking; 2. preventing and correcting functional deformities of the foot; 3. providing support for permanent model patients to achieve balance; 4. for pulling on spastic calf muscle groups and contracture achilles tendon; 5. strengthen and improve the clinical treatment effect.

The ankle-foot orthosis can prevent and correct foot deformation, control the angle of an ankle joint and achieve the effect of controlling the ground reflection force, thereby dispersing foot pressure and reducing pain; it is suitable for both moving and static ankles.

The ankle-foot orthosis has the following indications: the foot drop caused by various reasons is corrected, the foot is corrected, and the foot varus, the foot valgus, the ankle joint instability, the knee bend below the moderate degree and the knee joint hyperextension (knee distraction) are combined.
