Abstract

The invention discloses an active driving ankle foot orthosis with a plantar pressure detection function. The active driving ankle foot orthosis comprises a shank fixing component, a foot sensing component and an active driving component. The active driving component drives a driving bevel gear through a direct current motor; the driving bevel gear is meshed with a driven bevel gear; the driven bevel gear is mounted on a transmission shaft; a synchronous pulley, a synchronous belt and a tensioning screw are respectively formed at two ends of the transmission shaft. Seven film pressure sensors and an accelerometer are arranged in the foot sensing component. The active driving ankle foot orthosis has the advantages that on one hand, an intelligent pressure sensing foot is designed according to body bionics, a sensing heel and a sole are mutually connected through a spring steel sheet, the segmented structure of a human foot is simulated, and toes and the sole can be freely bent during walking, and on the other hand, active driving free degree is designed on the sagittal plane of an ankle joint, foot drop of a patient is prevented, meanwhile, power for the patient to go ahead is effectively provided through the driving of the direct current motor, and the walking load of the patient is reduced.

Description

technical field [0001] The present invention relates to an orthosis, more particularly, refers to an actively driven ankle-foot orthosis with a plantar pressure detection function. Background technique [0002] Orthotics are auxiliary medical devices that prevent or correct limbs and trunk deformities or treat bone, joint and neuromuscular diseases and compensate for their functions. [0003] An ankle-foot orthosis is an orthosis with a structure from the calf to the sole of the foot that controls the movement of the ankle joint. [0004] An important function of ankle-foot orthoses is to improve the abnormal gait of foot drop. Foot drop leads to the inability to dorsiflex the foot. When walking, the diseased foot is dragged or the lower limb is lifted higher. When landing, the toe always touches the foot. ground. Foot drop is a common complication in coma, paralysis, lower extremity dysfunction, and long-term bedridden patients. [0005] At present, ankle-foot orthoses a...
