Beijing Gao Cheng Medical Technology Co., Ltd. (hereinafter referred to as “Gao Cheng Medical”) has been awarded the Third Prize at the HICOOL 2025 Global Entrepreneurship Competition for its self-developed “Zhixiang™” Total Knee Arthroplasty Robot. Behind this success lies a strong collaboration between Shenzhen Zhanye Dahong Technology Co., Ltd. (Thingstest) and Atracsys.
The Zhixiang™ robot can perform sub-millimeter, dynamic 3D modeling of a patient’s bones in 30 seconds. Coming with an optical tracking system from the Swiss company Atracsys, it offers real-time and precise spatial positioning data. Using a dual closed-loop control mechanism combining visual servoing and follow-up tracking, surgeons can adjust osteotomy parameters in real time during surgery. Its foldable robotic arm reduces the footprint by 50% compared with traditional systems and its deployment beside the operating table takes as little as 15 minutes, making it ideal for diverse clinical settings, including ambulatory surgery centers and primary care clinics.
As an emerging company specializing in orthopedic robotics, Gao Cheng Medical’s project addresses key clinical pain points. Traditional orthopedic surgeries rely heavily on the surgeon’s experience and repeated intraoperative fluoroscopy, which not only limits precision but also exposes both patients and medical staff to radiation. “We were in urgent need of an optical tracking system capable of sub-millimeter accuracy, which is the foundation of any precise robotic navigation system,” explained Fu Mingjun of Gao Cheng Medical, noting that the company had previously encountered challenges in selecting the right technology.
This is where Zhanye Dahong, a medical equipment distribution specialist, played a key role in overcoming the challenge. With its network and experience representing global technology brands, Zhanye Dahong connected Gao Cheng Medical with Atracsys’s fusionTrack 500 optical tracking system and provided full technical support. “From communicating our needs to developing tailored solutions, Zhanye Dahong has built an efficient and collaborative bridge,” Fu added.
The high precision enabled by Atracsys technology played a key role in helping the project earn this award. The fusionTrack 500 system delivers real-time positioning accuracy of up to 0.1 mm, dynamically tracking the positions of surgical instruments and bones to construct a 3D navigation map for the robot. Its strong performance has already been proven in robotic and navigation surgery systems from leading companies. “This level of precision makes the robot truly a ‘perspective eye’ and a ‘steady hand’ for surgeons, one of the main reasons the project stood out among competitors,” noted the competition judges in their review. This success demonstrates the value of combining local partnership with world-class technology. With Zhanye Dahong (Thingstest) providing on-the-ground support and Atracsys its optical tracking expertise, Gao Cheng Medical was able to turn its vision for surgical precision into reality.
We at Atracsys are proud to contribute to the development of China’s next generation of surgical robots. If you are working on advanced navigation or robotic systems, we welcome the opportunity to explore potential collaborations.
