Solution overview
Minimally invasive head and neck procedures commonly face limited intraoperative visualization, blurred safety boundaries and high reliance on surgeon experience. Frequent intraoperative confirmation of critical anatomy prolongs operative time and increases procedural risk. The 艾瑞迈迪 solution provides image‑guided robotic navigation that reconstructs patient anatomy from preoperative CT/MRI, fuses endoscopic images intraoperatively and issues intelligent safety alerts to support precise ENT, skull base and neurosurgical interventions.

System modules

• Preoperative planning: multimodal image fusion; customizable tissue/organ segmentation; instrument trajectory and access planning
• Registration: T/C-type fiducial registration; 3D reconstruction alignment; laser-based registration
• Intraoperative navigation: dynamic trajectory guidance; audio-visual safety alerts; rapid instrument recognition and switching
• Endoscopic image fusion: endoscope tracking; fusion of endoscopic view with CT/MRI

Technical advantages

• One‑click non‑contact instant registration: 瑞瞳 binocular camera rapidly reconstructs the surgical surface point cloud and registers it to preoperative images with high accuracy
• AR surgical planning: 3D reconstruction of vessels and nerves to plan instrument paths that avoid critical anatomy
• Multimodal fused display: combined preoperative CT and real‑time endoscopic imaging to visualize subsurface structures and extend the surgical field
• Real‑time risk alerts: continuous distance calculation between instruments and vulnerable structures with proactive warnings
