The Youran URA Bedside Exoskeleton (Institutional Edition) is a NMPA-registered Class II medical device designed for rehabilitation of patients following lower-limb joint replacement surgery and those with lower-limb motor dysfunction in seated or supine positions. Through repeated, high-efficiency lower-limb joint movement training, it addresses joint stiffness and adhesion while promoting blood and lymphatic circulation and tissue repair.

Equipped with multi-sensor fusion technology, the URA detects the user's movement intent in real time and automatically adjusts impedance based on muscle strength changes to prevent spasticity. Therapists can record training movements for precise replay, enabling intelligent simulation of manual therapy techniques. All training data is logged and uploaded to the cloud for professional, quantitative rehabilitation assessment accessible to patients, families, and clinicians.

The device features an ergonomic, biomimetic design with flexible material straps for comfortable wear. Medical-grade casters enable easy repositioning between care settings. Multiple safety mechanisms — including real-time motion monitoring, automatic spasm/deviation protection, and emergency stop buttons on both the handle and main unit — ensure safe operation throughout every session.

Available in both battery-powered and plug-in configurations, the URA is suitable for rehabilitation medical institutions and hospitals. The full URA product line holds Class II medical device registration certificates covering neurological conditions including paraplegia and hemiplegia.
