Lower limb rehabilitation robot capable of balancing its own weight and method of using the same

Abstract

The invention relates to a lower limb rehabilitation robot capable of balancing its own weight, which mainly includes a hip joint assembly with a self-balancing device connected in sequence, a knee joint assembly capable of self-locking protection, an ankle joint assembly capable of self-locking protection, and a manual length adjustment assembly. Gaiters. The present invention designs a device for balancing the self-weight of the lower limb rehabilitation robot, which reduces the required output torque, thereby reducing the size of the drive system; the leggings device of the lower limb rehabilitation robot designed by the present invention can be adjusted along the leg direction, vertical Horizontal adjustment in the direction of the legs and quick disassembly; connected to the patient through the leggings at the thighs and legs, it can realize the rehabilitation training of the patient's hip joint flexion and extension, knee joint flexion and extension, and ankle toe flexion and dorsiflexion. and the calf can be adjusted in length; in addition, the present invention is simple in structure, easy to operate, small in size, light in weight and good in safety and protection, and conforms to the industry standard of medical equipment.

Description

technical field [0001] The invention relates to a rehabilitation robot, in particular, to a lower limb rehabilitation robot that can balance its own weight. Background technique [0002] The lower extremity rehabilitation robot is designed to deal with the injury of the lower extremity of the patient, and is provided to patients with spinal cord injury, cerebral palsy or patients with limb injury after surgery to provide patients with effective lower extremity rehabilitation training. When the patient performs gait action, the joint activity of the robot drives the patient's movement, thereby activating the injured part of the patient and playing a role in rehabilitation therapy. [0003] There are many types of existing lower limb rehabilitation robots, most of which use the mechanism of exoskeleton robots. Due to the complexity of the driving system and mechanical structure of exoskeleton robots, the size, weight and safety of the robot are often poor, and the robot has a ...

AI Technical Summary

Problems solved by technology

[0003] There are many types of existing lower limb rehabilitation robots, most of which use exoskeleton robot mechanisms. Due to the complexity of the drive system and mechanical structure of exoskeleton robots, the size, weight and safety of the robot are often poor, and the robot has a large weight. The drive system needs to drive its own weight, which leads to higher requirements for the drive system, which in turn increases the size of the robot; in addition, most of the leggings of existing lower limb rehabilitation robots can only be adjusted in the length direction of the straps, and few of them can adjust the length of the straps. Longitudinal adjustment along the leg direction during work to alleviate the discomfort caused by the straps pulling on the patient during movement; and there is no lateral position of the leggings device relative to the mechanical leg, so that the lower limb rehabilitation robot cannot be used for poor leg straightness patients, such as those with X-legs or O-legs

In addition, most of the leggings are fixed on the mechanical legs and cannot be disassembled quickly, which is inconvenient for medical staff to operate
