Upper limb rehabilitation mechanical arm and robot for patients with spinal cord injury

Abstract

The invention belongs to the technology of rehabilitation mechanical equipment, and particularly relates to an upper limb rehabilitation mechanical arm and robot for patients with spinal cord injury.A shoulder joint assembly comprises a static platform fixed to a mechanical arm fixing rod, a movable platform opposite to the static platform, three shoulder joint motor supports and a shoulder jointgear motor, wherein an output shaft of the shoulder joint gear motor is connected to one end of a first connecting rod fixing frame, and the other end of the first connecting rod fixing frame is connected to a first shoulder joint connecting rod; one end of the first shoulder joint connecting rod is rotationally connected to the shoulder joint motor supports through bearings, and the other end ofthe first shoulder joint connecting rod is rotationally connected with one end of a second shoulder joint connecting rod; the other end of the second shoulder joint connecting rod is rotationally connected with a base plate fixed to the movable platform; and the shoulder joint assembly forms a 3-RRR parallel mechanism. The rehabilitation training requirements corresponding to upper limb joints ofthe patients at different stages can be met, three joint training modules including the shoulder joint training module, the elbow joint training module and the wrist joint training module are included, five degrees of freedom of the upper limbs of the patients are trained, and rehabilitation training of the patients is more comprehensive.

Description

technical field [0001] The invention belongs to the technical field of rehabilitation machinery and equipment, and in particular relates to an upper limb rehabilitation mechanical arm and a robot for patients with spinal cord injuries. Background technique [0002] Spinal cord injury is a catastrophic injury that leads to lifelong disability. In my country, there are 100,000 to 140,000 new patients with traumatic spinal cord injury every year, and the total number of patients has reached more than 2 million, which brings a heavy burden to families and society. Patients with spinal cord injury generally need long-term rehabilitation treatment, but traditional rehabilitation treatment methods are labor-intensive and risky, which has become a bottleneck restricting patients from receiving timely, adequate and standardized rehabilitation treatment. [0003] In recent years, many upper limb rehabilitation robots have appeared on the market, but patients with spinal cord injuries ...
