Santan Medical

Hangzhou Santan Medical Technology serves as Vice Chairman of the Medical Robotics Branch of the China Medical Device Industry Association, positioning the company among the first-tier domestic manufacturers developing autonomous orthopedic surgical robot core technologies. Founded in 2011, the company has built a portfolio of over 70 patents in AI image processing and surgical navigation, including defense invention patents that distinguish it within the industry.

Company Overview

Santan Medical emerged from a collaboration between leading medical experts and engineers focused on addressing the challenges of bone surgery precision. The invisibility of bone structures during surgery and the requirement for high-strength cutting make maintaining accuracy and stability particularly difficult. The company’s approach centers on developing intelligent surgical assistance solutions that enhance visualization and guidance during orthopedic procedures.

The company operates from its headquarters in Hangzhou’s West Lake Science and Technology Park and maintains research partnerships with prominent institutions including Zhejiang University, Shanghai Jiao Tong University, Second Military Medical University, Zhejiang University of Traditional Chinese Medicine, PLA General Hospital, and the Second Affiliated Hospital of Zhejiang University School of Medicine. These academic-medical collaborations form the foundation of the company’s product development platform.

Founder Shen Liping holds the majority stake in the company, with He Bin serving as a key member of the founding team. The company’s national high-tech enterprise certification reflects its R&D intensity in the surgical robotics field.

Core Products

Zhiwei Tianyan® Surgical Navigation System

The flagship product line, Zhiwei Tianyan® (Smart Eye of Heaven), provides surgical guidance and feedback capabilities for orthopedic procedures. The system has achieved a technological breakthrough by moving beyond traditional three-dimensional coordinate calculation methods used in surgical navigation, implementing a two-dimensional to three-dimensional switching function that enhances intraoperative visualization.

The system applies laser positioning and navigation technology across multiple orthopedic subspecialties including spine surgery, trauma surgery, and joint replacement procedures. Products in this series have received NMPA certification for clinical use in China.
