Ankle rehabilitation exoskeleton device

Abstract

The invention provides an ankle rehabilitation exoskeleton device, which comprises the following devices: a signal transmission device, a control device, a driving device, a transmission device and a memory device, wherein the signal transmission device comprises a force sensor and a rotation sensor; the force sensor is used for detecting pressure signals of the transmission device and the rotation sensor is used for detecting a rotation direction of the transmission device; the control device is used for controlling the driving device to run in accordance with signals received from the signal transmission device, wherein the signals of the signal transmission device include the pressure signals and rotation direction signals; the driving device, under the control of the control device, is used for driving the transmission device and for outputting transmission data; the transmission device, under the driving of the driving device, is transmitted; and the memory device is used for receiving and keeping transmission data outputted from the driving device in real time. The ankle rehabilitation exoskeleton device provided by the invention has the advantages of being compact in structure, delicate in design, small in volume, low in cost and convenient to wear; external force weakness and direction can be adjusted in real time in accordance with exercise situation of a user; and by arranging data recording, analysis and statistic can be conducted on an ankle recovery situation, so that personalized treatment is achieved.

Description

technical field [0001] The invention relates to the field of ankle rehabilitation, in particular to an ankle rehabilitation exoskeleton device. Background technique [0002] Ankle fractures are very common in daily life. People are prone to ankle fractures if they do not pay attention to self-protection in daily life, especially during sports. Ankle fractures require a certain rehabilitation period, during which time you cannot walk. When the ankle is about to heal, the patient needs to undergo a series of rehabilitation exercises to speed up recovery, among which walking rehabilitation training is the most simple and effective. However, walking for a long time will lead to excessive burden on the rehabilitation ankle, which is not conducive to the further rehabilitation of the ankle. Most of the existing devices play a role of return force through material shock absorption; or through a motor to provide a fixed torque. As a result, the movement strength and range of the ...

AI Technical Summary

Problems solved by technology

As a result, the strength and range of ankle joint movement are limited, and it is impossible to record various data (such as torque magnitude and force time) during exercise to provide personalized treatment and medical analysis data

Some large-scale rehabilitation devices have relatively complete functions, but they are inconvenient to carry and walk when used. They can only be used as auxiliary tools for rehabilitation treatment, and they are expensive

[0003] A patent with a patent application number of 200910088396.9 provides a wearable lower limb exoskeleton device with multi-degree-of-freedom movement; it is driven by a motor to help people with mild impairments in lower limb movement to achieve rehabilitation, but the motor torque needs to be input with a fixed value. Unable to control in real time, and unable to display and store data;

[0004] A patent with the patent application number 201610347204 discloses a wearable ankle protection and foot booster device, which uses shock-absorbing materials and has a pull-back function; Correction” field; but without external force input, it can only act as a buffer, and cannot display the stored data
