Problems solved by technology

Although the ankle dorsiflexion AFO can allow some patients to exert their own ankle dorsiflexion function, it limits the ankle plantar flexion function, and some patients are weak in ankle dorsiflexion itself, and cannot exert ankle dorsiflexion function in the normal walking cycle

Abstract

The invention provides a knee-powered radian pulley-type foot drop and hemiplegic gait orthosis and relates to the technical field of medical rehabilitation instruments. The orthosis comprises an above-knee thigh orthosis component (1), thigh orthosis mechanism fixing parts (2), a shank orthosis component (3), shank orthosis component fixing parts (4), a crank lever assembly, a foot support connection rope (5) and a foot support (6), wherein the above-knee thigh orthosis component (1) and a thigh orthosis mechanism fixing part (2) are both provided with opening ends, two sides of each of the opening ends are connected with the thigh orthosis mechanism fixing parts (2) and the shank orthosis component fixing parts (4) respectively, and the crank lever assembly comprises a crank lever (7), a crank lever rotary shaft (8) and a pair of pulleys (9) used for limiting the moving space of the crank lever. The knee-powered radian pulley-type foot drop and hemiplegic gait orthosis can be effectively used for rehabilitation training on lower limbs of patients suffering from apoplexy hemiplegia and can correct the gait of the patients.

Description

technical field [0001] The invention relates to the technical field of medical rehabilitation equipment, in particular to a knee dynamic radian pulley type foot drop and hemiplegia gait corrector. Background technique [0002] The lower limbs of stroke patients with hemiplegia often show a flexion spastic pattern, ankle-foot plantarflexion and varus deformity, insufficient ankle dorsiflexion, and a circular gait when walking. Fracture patients cause weakness of the tibialis anterior muscle after common peroneal nerve injury, and ankle dorsiflexion No, it manifests as foot drop, which seriously affects the patient's walking gait. Clinically, ankle foot orthosis (AFO) is often used to correct it. AFO can correct and prevent Achilles tendon contracture, partially improve the stability of the patient's walking gait, and restore the patient's walking ability to varying degrees. It has been widely used in clinical practice. Although the ankle dorsiflexion AFO can allow some patie...
