Embodiment Construction

[0036] In order to make the object, technical solution and advantages of the present invention clearer, the present invention is described below through specific embodiments shown in the accompanying drawings. It should be understood, however, that these descriptions are exemplary only and are not intended to limit the scope of the present invention. Also, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concept of the present invention.

[0037] The connection mentioned in the present invention is divided into fixed connection and detachable connection. The fixed connection is a non-detachable connection including but not limited to conventional fixed connection methods such as hemming connection, rivet connection, adhesive connection and welding connection. Detachable connections include but are not limited to conventional disassembly methods such as bolt connections, snap connections, pin con...

Abstract

The invention discloses an ankle-knee linkage walking assisting device, belongs to the field of medical instruments, and aims to solve the problem that an existing walking training assisting method is poor in treatment effect or expensive in equipment and cannot be popularized and used. The ankle-knee linkage walking assisting device comprises a knee joint wearing body, an ankle wearing body and a plurality of stay wires. The tension angle and the tension force of each stay wire are dynamically adjusted by adjusting the length of the stay wires and the position of a sliding screw, the posture of the ankle is limited by the tension force of the stay wires, the gentle flexion of the knee is controlled to be within 10 degrees, the dorsal flexion of the ankle is controlled to be larger than 0 degree, the consistency of each exercise training is guaranteed, through repeated exercise, exercise dynamic shaping reconstruction is realized, and action reflection is formed, so that the gait is fixed. By means of the open-chain and closed-chain motion principle, the far-end motion freedom degree is limited through ankle-knee combination, near-end control is strengthened, far-end abnormal modes are reduced, and the purposes of labor saving and auxiliary therapy are achieved.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to an ankle-knee linkage walking assist device. Background technique [0002] Improvement of walking ability is crucial for the ADL ability of stroke patients, affected by abnormal movement patterns and muscle spasticity of the lower limbs, stroke patients often show a circle gait, accompanied by knee flexion and foot drop varus Two pathological features. [0003] There are many existing walking training auxiliary methods: as the strap method and the training method with the help of ankle-foot orthosis or lower limb rehabilitation robot. Among them, the strap method and the walking training aid method with the help of ankle-foot orthosis are relatively simple, but they are poor in comfort and effect, and ignore the coordination of the joints of the lower limbs during walking and the correlation of various movement reflexes, and cannot be dynamically adjusted. ; However, lower limb r...
