Lower Limb Exoskeleton Robot

Ruihan Medical’s Lower Limb Exoskeleton Robot provides powered gait rehabilitation for patients with lower extremity motor dysfunction. Available in both bedside and standalone configurations, the exoskeleton system supports walking rehabilitation for stroke survivors, spinal cord injury patients, and those with other neurological conditions affecting ambulation.

Product Overview

The Lower Limb Exoskeleton Robot extends Ruihan Medical’s rehabilitation portfolio beyond upper extremity and hand function to address the critical need for gait restoration. The system provides motorized assistance at hip and knee joints to enable repetitive, controlled walking movements that promote neural pathway reorganization and muscle strengthening.

Designed for use within medical rehabilitation facilities, the exoskeleton can be configured for bedside training in patients with limited mobility or standalone gait training for those progressing toward independent ambulation.

Key Features

Ruihan Medical’s Lower Limb Exoskeleton Robot is a powered hip-and-knee rehabilitation system, featuring intention-based control with machine learning adaptation and cloud-connected training data management across bedside and standalone configurations.

• Intention Control: Sensing of exercise intention enables active rehabilitation paradigm where patient effort triggers assistance
• Machine Learning Adaptation: System learns and adapts to individual patient movement patterns over time
• Interactive Force Control: Force-sensitive feedback creates natural-feeling assistance described as “just right”
• Multiple Configurations: Bedside and standalone versions accommodate patients at different recovery stages
• Cloud Data Processing: Training data visualization and online evaluation records support progress tracking
• Intelligent Rehabilitation Management: Full support for prescription, data, report, and medical record management

Technical Specifications

Ruihan Medical’s powered lower limb exoskeleton is a hip-and-knee intention-based rehabilitation system featuring machine learning adaptive control, cloud data visualization, and bedside or standalone configurations for stroke, spinal cord injury, and cerebral palsy.

Clinical Applications

The exoskeleton is indicated for gait rehabilitation in patients with lower extremity motor dysfunction caused by:

• Stroke affecting lower limb motor function
• Spinal cord injury with preserved lower motor neurons
• Cerebral palsy affecting ambulation
• Generalized muscle weakness limiting walking ability

The system supports rehabilitation protocols focused on repetitive task-specific training, which research has shown to be effective in promoting functional recovery through neural plasticity mechanisms.

Regulatory Status

The product is part of Ruihan Medical’s pipeline of rehabilitation devices. The company has obtained seven Class II NMPA registrations for its broader rehabilitation portfolio, with additional products in the registration process.

Frequently Asked Questions

What is the difference between bedside and standalone exoskeleton configurations?

The bedside exoskeleton is designed for patients with limited mobility who require training while remaining near their hospital bed. It provides supported gait practice without requiring the patient to stand independently. The standalone configuration is for more advanced patients who can tolerate upright walking with robotic assistance, typically used in dedicated rehabilitation gym settings.

How does the intention control feature work?

The exoskeleton incorporates force and motion sensors that detect when the patient initiates movement. When the system senses the patient’s intention to take a step, it provides motorized assistance to complete the movement. This approach keeps the patient actively engaged in the rehabilitation process rather than relying on purely passive movement.

Can the exoskeleton be used with Ruihan’s BCI system?

Ruihan Medical’s product ecosystem is designed for potential integration across devices. The lower limb exoskeleton’s intention control system can theoretically interface with the company’s brain-computer interface platform, though clinical protocols would need to be established for combined use.
