Ruihan Medical

Ruihan Medical has established itself as a leading developer of brain-computer interface (BCI) rehabilitation robotics in China. As a controlled subsidiary of Lepu Medical (300003.SZ), the company operates from Shenzhen’s Pingshan District, where it has built the world’s first commercially available BCI-based hand function rehabilitation robot system.

Company Overview

Founded in May 2016 by Dr. Wang Jing, a postdoctoral researcher from Georgetown University and professor at Xi’an Jiaotong University’s School of Mechanical Engineering, Ruihan Medical emerged from over a decade of research in EEG signal processing and brain-computer interfaces. The company was designated as a National High-tech Enterprise and selected for the Ministry of Industry and Information Technology’s AI Medical Device Innovation Task as part of the “open competition” program.

The founding team brings expertise from leading Chinese universities including Tsinghua University, Xi’an Jiaotong University, Sun Yat-sen University, and Shenzhen University. In late 2021, Lepu Medical made a strategic investment that eventually resulted in controlling ownership (approximately 50.08% stake), providing Ruihan with the resources to accelerate commercialization of its research-stage technologies.

Core Products

BCI Hand Function Rehabilitation Robot System

The company’s flagship product combines non-invasive brain-computer interface technology with robotic hand rehabilitation. The system captures motor intention signals from the brain using proprietary wireless EEG acquisition technology, then translates these signals to control a mechanical hand orthosis that assists patients in completing movements. This closed-loop approach—from central nervous system to peripheral movement and back—is grounded in neuroplasticity and mirror neuron theory.

The hand rehabilitation robot supports 24 different fine motor movements and has been deployed in over 100 hospitals and research institutions across China, treating tens of thousands of patients to date.

Upper and Lower Limb Active-Passive Training System

This rehabilitation system responds to BCI commands to provide coordinated upper and lower limb training. It can integrate with third-party upper limb robots to enable fine motor tasks such as writing exercises, while also supporting lower limb rehabilitation protocols.

Lower Limb Exoskeleton Robot

Ruihan has developed multiple exoskeleton configurations including bedside and standalone versions for lower limb rehabilitation in stroke and spinal cord injury patients.

Wireless Digital EEG Analysis and Recording System

The company’s proprietary wireless EEG system provides the sensing foundation for its BCI products, featuring noise reduction algorithms refined through deep learning iterations.

Technology & Innovation

Ruihan Medical’s core competencies center on non-invasive brain-computer interface technology, including:

• Proprietary wireless EEG acquisition hardware with advanced signal processing
• Motor imagery decoding algorithms representing international frontier research
• Central-peripheral-central closed-loop neural rehabilitation methodology
• Adaptive training difficulty adjustment based on real-time brain activity monitoring
• Real-time brain topography display showing activated cortical areas

The company holds over 100 patents and software copyrights, including more than 30 invention patents. Its technical approach emphasizes practical commercialization of BCI technology in clinical rehabilitation settings.

Frequently Asked Questions

What types of patients can benefit from Ruihan Medical’s rehabilitation robots?

Ruihan Medical’s products are designed for patients with motor dysfunction caused by stroke, spinal cord injury, traumatic brain injury, and peripheral nerve damage. The BCI-based systems are particularly suited for hand function rehabilitation in stroke survivors during subacute and chronic recovery phases.

Is Ruihan Medical a publicly traded company?

Ruihan Medical itself is not publicly traded. However, it is a controlled subsidiary of Lepu Medical (300003.SZ), a major Chinese medical device company listed on the Shenzhen Stock Exchange. Lepu Medical holds approximately 50.08% of Ruihan Medical.

How does Ruihan’s BCI technology differ from traditional rehabilitation approaches?

Traditional rehabilitation relies on passive or therapist-assisted movements. Ruihan’s BCI system captures the patient’s motor intention directly from brain signals, creating an active rehabilitation paradigm where the patient’s mental effort drives the robotic assistance. This closed-loop approach has shown effectiveness rates of approximately 80% in promoting neural recovery.
