Optical positioning system Ruitong® PRO

surgeryfor surgical navigation

Product description
瑞瞳®PRO is a multi‑source spatiotemporal optical‑field fusion visual reconstruction and localization system that integrates tracking, 3D surface reconstruction, scene mapping and laser localization. Designed for large surgical fields, it delivers a high‑precision visual navigation platform suitable for medical, industrial and entertainment applications.

Key technologies

• Fully automatic — instant registration
  • One‑click, non‑contact registration completes preoperative setup in seconds.
  • Real‑time intraoperative drift correction substantially improves target tracking accuracy.
• Full optical field — optical‑field guided imaging
  • High‑definition omnidirectional 3D reconstruction captures high‑dimensional surgical scene information.
  • Integrated synchronized localization links reconstructed scene data with instrument poses.
• Full field of view — mixed reality fusion
  • Precise fusion of live intraoperative video streams with critical anatomical information.
  • Dynamic augmented reality provides comprehensive perceptual overview across the entire surgical field.
• All‑scenario — multi‑source visual sensing
  • Flexible combination of optical modules to meet specific scene requirements.
  • Smart perception merged with cutting‑edge vision algorithms to enable new applications.

Application scenarios

• All‑scene perception — 瑞瞳®PRO captures instrument, tissue and robotic arm poses and structures across the surgical field, enabling full‑scene 3D reconstruction and automatic recognition for surgical path planning.
• Real‑time visualization — Accurate augmented reality overlays expose vessels, critical nerves and planned trajectories that are not directly visible, supporting intraoperative decision making.
• Fully automatic calibration — Supports manual and automatic region‑of‑interest detection, reducing registration time to seconds while maintaining sub‑millimetre reconstruction and localization accuracy.
• Full‑field navigation — Integrated multimodal image reconstruction fuses 2D/3D sources to provide immediate, multi‑dimensional navigation information during procedures.
• Optical‑field monitoring — Dynamic intraoperative monitoring uses high‑sensitivity optical sensors and real‑time processing to detect micro‑motions and automatically re‑register, ensuring long‑term localization accuracy.
