Walking machine for paraplegics is a medical-grade wearable robotic lower limb exoskeleton developed for paraplegic patients, spinal injury sufferers and individuals with complete lower limb movement dysfunction. Integrated with professional bionic gait planning system, multi-dimensional safety sensors and stable high-torque servo motors, this walking machine for paraplegics delivers full active power assistance to hips, knees and ankles, enabling users to safely stand upright, walk straight, turn and traverse gentle slopes under auxiliary protection. Multiple built-in safety protections including anti-fall prompt, overload stop and emergency shutdown effectively prevent secondary injuries during rehabilitation training. The lightweight medical composite frame supports IP54 dustproof and waterproof performance, perfectly fitting hospital rehabilitation departments, professional training institutions and household daily recovery use. Widened soft padded binding belts with full-range size adjustment adapt to various body types and leg lengths of patients, equipped with interchangeable long-life lithium batteries to sustain long-duration continuous training. Equipped with intuitive handheld control panel and auxiliary standing structure, it lowers operation difficulty for patients and caregivers. This rehabilitation walking machine improves lower limb blood circulation, relieves muscle atrophy, joint stiffness and bedsores, helps paraplegic users regain basic walking capacity and greatly enhances their self-reliance and life quality.
