Zhiwei Tianyan Surgical Navigation System

Developed by Santan Medical, the Zhiwei Tianyan® (智微天眼, “Smart Eye of Heaven”) represents a surgical navigation and feedback system that employs AI image processing and laser positioning technology to guide orthopedic procedures. The system addresses the fundamental challenge of bone invisibility during surgery by providing real-time positioning guidance across spine, trauma, and joint surgery applications.

Product Overview

The Zhiwei Tianyan system breaks from traditional surgical navigation approaches that rely on three-dimensional coordinate calculation methods. Instead, it implements a proprietary two-dimensional to three-dimensional switching function that enables surgeons to transition smoothly between imaging modalities during procedures. This architectural difference allows for more intuitive interaction with surgical guidance data while maintaining positioning precision.

The product serves hospitals seeking both practical utility and customization capability in surgical guidance technology. Its design philosophy emphasizes clinical workflow integration rather than requiring fundamental changes to surgical technique.

Key Features

Designed for spine, trauma, and joint surgery on a single platform, Zhiwei Tianyan combines AI image processing with proprietary 2D-to-3D switching for real-time intraoperative positioning guidance.

• Laser Positioning Navigation: High-precision laser guidance system for instrument placement and trajectory verification
• AI Image Processing: Machine learning algorithms that process imaging data to identify bone structures and calculate optimal surgical paths
• 2D-3D Conversion: Real-time switching between two-dimensional and three-dimensional visualization modes
• Multi-Specialty Application: Single platform supporting spine, trauma, and joint surgery requirements
• Feedback System: Intraoperative feedback mechanisms confirming instrument position relative to planned trajectory

Technical Specifications

Designed for spine, trauma, and joint procedures, Zhiwei Tianyan uses laser positioning with AI-enhanced 2D/3D conversion and NMPA-approved clinical deployment across Chinese hospitals.
