Multifunctional gait rehabilitation machine

Abstract

The invention discloses a multifunctional gait rehabilitation machine. The multifunctional gait rehabilitation machine comprises bottom frames, a driving device, a supporting device, a gait part, a sliding device and a pedal mechanism; a bottom plate is welded between the bottom frames; the driving device is formed on the left side of the upper surface of the bottom frame, and comprises a mounting plate; the supporting device is formed on the left side of the upper surface of the bottom frame, and comprises a pair of U-shaped frames and a pair of supporting columns; the lower end faces of the pair of U-shaped frames are welded and fixed to the mounting plate; the lower surfaces of the pair of supporting columns are in threaded connection with the two ends of the pair of U-shaped frames; a connecting plate is fixedly mounted between the pair of supporting columns through bolts; the gait part is formed on the front surface of the connecting plate; the sliding device is formed on the bottom plate on the right side of the driving device; and the pedal mechanism is formed on the bottom plate on the right side of the sliding device, drives a first screw rod to rotate through a first motor to change the angle between a thigh part and a cross beam, drives a second screw rod to rotate through a second motor, and changes the angle between the thigh part and a shank part through the cooperation between the second screw rod and a second screw rod nut so as to simulate rehabilitation exercise and help a patient to rehabilitate.

Description

technical field [0001] The invention belongs to the technical field of medical rehabilitation machinery and equipment, and in particular relates to a multifunctional gait rehabilitation machine. Background technique [0002] Weight loss walking rehabilitation training is the most widely used lower limb rehabilitation training method in recent years. There are many problems in traditional manual walking rehabilitation training, such as the labor intensity of the therapist, the training effect is too dependent on the experience and level of the therapist, and it is difficult to ensure that the patient can obtain Sufficient training intensity and training cycle, etc.; [0003] The multi-functional gait rehabilitation machine overcomes the shortcomings of traditional manual rehabilitation training, and is an effective means of gait rehabilitation training for patients with gait abnormalities caused by motor nervous system diseases. The multi-functional gait rehabilitation machin...

Problems solved by technology

The leg-driven gait rehabilitation machine usually adopts the form of exoskeleton. Its limitation is that the degree of freedom of the mechanical joints is less than that of the actual human joints, and it cannot accurately reproduce the joint movements in normal gait, and it is uncomfortable to wear.

The foot-driven gait rehabilitation training machine drives the patient's feet to move through the exercise pedals, and then the patient's big and small legs move together. However, the existing foot-driven lower limb rehabilitation machines usually use a fixed mechanism To achieve an ellipse-like motion trajectory, the trajectory of the foot movement cannot be flexibly adjusted according to the patient's physical condition and training needs, and it is difficult to achieve the ideal rehabilitation effect
