China develops a medical assistant robot to complete its first clinical application

China News Service, Beijing, April 2 — Reporter Sun Zifa — Institute of Automation, Chinese Academy of Sciences — On April 2, the institute notified the media that a medical assistive robot jointly developed by the institute and an enterprise has, in recent days, completed its first clinical application in the Hong Kong Special Administrative Region, and the patient’s condition is good after surgery.

The robot, named the “Robot-Assisted Transcatheter Tricuspid Valve Replacement TTVR System(,” integrates high-precision motion control, active safety constraints, and intelligent navigation technologies, achieving stable and precise instrument manipulation and ensuring the safety and reliability of key operational steps. Compared with traditional manual operation, the robot-assisted system is expected to reduce complications that may be caused by doctors’ slight hand tremors and differences in operating range, improve the accuracy of valve implantation, and shorten surgery time.

The robot platform adopts a master-slave control architecture, enabling the lead surgeon to perform remote and distance operations, which significantly reduces doctors’ radiation exposure during surgery and lowers occupational health risks. In addition, the system integrates remote operation functions, and has potential to support cross-regional surgical collaboration.

“The Robot-Assisted Transcatheter Tricuspid Valve Replacement System” clinical application research for this round is undertaken by the core technology R&D team led by researchers Hou Zengguang and Wang Shuangyi from the Institute of Automation, Chinese Academy of Sciences, and carried out in close cooperation with the Faculty of Medicine at the Chinese University of Hong Kong; the Hong Kong Innovation Research Institute of the Chinese Academy of Sciences provides important support for cross-border scientific research collaboration. Core team members Xie Yiping and Lin Haichuan participated deeply in the work of technical support and clinical support for the surgery.

For the first clinical application surgery with this robot, it was successfully carried out in late March at Prince of Wales Hospital in Hong Kong. The lead surgeon was Dr. Su Zeyu’s team, with Dr. Su Zeyu serving as an assistant professor in the Department of Medicine and Therapeutics at the Chinese University of Hong Kong, and a transcatheter tricuspid valve was precisely implanted for a patient with severe tricuspid regurgitation. Postoperative assessment showed that the tricuspid regurgitation completely disappeared, and the patient’s condition after surgery is good.

It is reported that the “Robot-Assisted Transcatheter Tricuspid Valve Replacement System” platform was jointly developed by the Institute of Automation, Chinese Academy of Sciences, and Ningbo Jianshi Technology Co., Ltd. The successful launch of its first clinical study marks an important step forward in the system’s clinical application, laying an important foundation for subsequent large-scale use and broad-based promotion.)End(
