3D printing ankle-foot orthosis

Abstract

The application provides a 3D printing ankle-foot orthosis, which comprises an ankle-foot orthosis body, an electric stimulation device and a film pressure sensor, wherein the ankle-foot orthosis bodyconsists of a lower leg supporting part, an ankle-foot fixing part and a foot support; a reserved position corresponding to the common peroneal nerve of a human body is arranged at the upper end of the inner side of the lower leg supporting part to place the electric stimulation device; the film pressure sensor is arranged in the heel of the foot support; and a data line is arranged on the film pressure sensor for connection with the electrical stimulation device. The device can prevent and correct deformities, improve abnormal gait of lower limbs, improve walking efficiency, accelerate localblood circulation, prevent muscle ischemic atrophy, and greatly reduce the risk of inducing deep vein thrombosis.

Description

technical field [0001] This application relates to the technical field of orthopedic appliances, in particular to a 3D printed ankle-foot orthosis. Background technique [0002] Stroke is one of the diseases with high morbidity and high fatality rate in the world. There are 2 million new patients every year. After stroke, patients will have different degrees of hemiplegia. About three-quarters of hemiplegic patients need assistance in life. The post-stroke foot drop and inversion have always been one of the difficult problems in the rehabilitation process of stroke patients with hemiplegia, seriously affecting the patient's walking ability and walking efficiency, and reducing the quality of daily life. Hemorrhagic atrophy and disability, wearing ankle-foot orthosis is one of the main means to treat foot drop and inversion. Ankle-foot orthosis has a structure from the calf to the sole of the foot, mainly composed of the calf support part, the ankle-foot fixation part and the ...

AI Technical Summary

Problems solved by technology

[0003] Ankle-foot orthoses can prevent and correct deformities in the treatment of post-stroke hemiplegia, and play an important role in improving patients' abnormal gait and improving walking efficiency. However, the traditional ankle-foot orthoses currently on the market have a complicated and cumbersome manufacturing process. , Unsightly, and cannot match the actual condition of the patient's foot, resulting in low compliance of the patient after wearing it, resulting in a greatly reduced treatment effect, and wearing ankle-foot orthoses for a long time, due to the long-term braking of the foot, the surrounding blood circulation is not smooth , and cause ischemic muscle atrophy of the foot, and even have the risk of inducing deep vein thrombosis of the foot
