Overview
An orthopedic robotic navigation solution that integrates high-precision positioning sensors, a robotic arm, advanced AI algorithms and 3D medical image processing. The system imports and analyzes patient CT and multimodal images to reconstruct accurate 3D bone models. Intraoperatively it executes precise bone cuts, drilling and implant positioning, improving surgical accuracy and intraoperative control. Based on its technology platform, 艾瑞迈迪 delivers customized navigation solutions for total knee arthroplasty (TKA), unicompartmental knee arthroplasty (UKA), hip replacement and pedicle screw placement.

System modules

• Image processing
  • Automatic bone and soft-tissue segmentation
  • Multimodal image registration and fusion
  • 3D bone reconstruction and visualization
  • AI-assisted lesion detection and annotation
• Preoperative planning
  • Patient-specific implant design and selection
  • Implant positioning and angular planning
  • Osteotomy plane and approach planning
  • Automated bone morphology measurements
  • Surgical simulation and collision checking
• Intraoperative navigation
  • High-precision surface registration (point-cloud/mesh matching)
  • Real-time tracking of bone surface

Technical advantages

• One-step non-contact instant registration: the 瑞瞳系列 binocular cameras enable fast high-precision surface reconstruction, aligning point-cloud data with preoperative images in a unified coordinate system.
• Intraoperative simulation and assessment: real-time synchronization between preoperative 3D bone models and intraoperative bone motion supports precise ligament balancing measurements across operative modes.
• Augmented reality surgical visualization: overlays of preoperative 3D images and virtual instrument data onto live patient video, supporting AR, holographic projection and VR fusion to enhance intraoperative anatomical awareness.
• Robotic arm motion control: integrated safety boundary constraints, trajectory planning, real-time collision avoidance and autonomous mobility to ensure precise and controlled intraoperative actions.
