Smart Orthopedic Surgery Navigation Robot System
The Smart Orthopedic Surgery Navigation Robot System from Weizhuo Zhiyuan represents one of the few NMPA-approved systems capable of serving both spine surgery and trauma orthopedic procedures while enabling 2D-3D registration functionality.
Product Overview
This navigation robot system delivers intelligent surgical guidance through an integrated platform combining preoperative planning, intraoperative navigation, and real-time visualization. The system addresses the clinical need for precision in complex orthopedic procedures while minimizing radiation exposure through its zero-fluoroscopy operation capability.
Unlike traditional orthopedic surgical approaches requiring frequent X-ray imaging, this system uses advanced image registration algorithms to provide continuous surgical guidance without repeated fluoroscopy, benefiting both patients and surgical teams.
Key Features
For orthopedic surgeons performing both spine and trauma procedures, Weizhuo Zhiyuan’s navigation robot fuses 2D-3D imaging to guide instruments in real time without continuous fluoroscopy.
2D-3D Image Registration: Proprietary algorithms enable rapid fusion of preoperative 3D imaging with intraoperative 2D fluoroscopy, providing accurate spatial positioning without continuous radiation exposure
Intelligent Surgical Planning: AI-powered preoperative planning module automatically segments anatomical structures and suggests optimal surgical pathways based on patient-specific imaging data
Real-Time Navigation: Continuous tracking of surgical instruments relative to patient anatomy, displayed through intuitive interface allowing surgeons to verify positioning accuracy
Multi-Modality Compatibility: Supports integration with CT, MRI, and intraoperative imaging systems for thorough surgical guidance
Digital Implant Library: Pre-loaded database of orthopedic implants enabling accurate preselection and virtual placement verification during surgical planning
Technical Specifications
Deployed in over 300 hospitals across 5,000+ procedures, this NMPA Class III system delivers sub-millimeter navigation using 2D-3D fusion, optical tracking, and a pre-loaded implant library.

| USA (FDA) | Not Applied | - |
The system has achieved NMPA approval as a Class III medical device, making it among the limited number of approved orthopedic navigation systems with dual capability for both spine and trauma applications.
Frequently Asked Questions
What procedures can the Smart Orthopedic Navigation Robot perform?
The system supports spine surgery procedures including pedicle screw placement and spinal fusion, as well as trauma orthopedic procedures such as pelvic fracture fixation and complex acetabular surgery. Its dual-indication approval distinguishes it from single-specialty navigation systems.
How does the zero-fluoroscopy feature work?
Through 2D-3D registration technology, the system creates a spatial map from preoperative CT/MRI imaging that aligns with minimal intraoperative fluoroscopy. Once registered, surgeons can navigate instruments in real-time without repeated X-ray imaging, significantly reducing radiation exposure.
What training is required for surgeons?
Weizhuo Zhiyuan provides full training programs including system operation, surgical workflow integration, and ongoing technical support. The company collaborates with the National Clinical Research Center for Orthopedics and Sports Medicine Rehabilitation on standardized training protocols.
