China’s first approved vascular robot achieves 100% success rate in clinical trial

Researchers in China have successfully validated the YDHB-NS01, the country’s first domestically produced vascular robot designed for cerebral angiography, achieving a 100% technical success rate in a clinical trial at Peking Union Medical College Hospital (PUMCH). The trial involved 50 patients, with 25 procedures performed using the robotic system and 25 manually by a young neurosurgeon. The robot-assisted procedures reduced the average surgery time by 29%, from 38 minutes to 27 minutes, while maintaining comparable safety, image quality, and radiation exposure to the conventional manual approach. The robotic system allows surgeons to operate remotely from a shielded console, reducing physical strain and radiation risk. The study highlights that the robotic system offers a stable, precise alternative to manual cerebral angiography, which is traditionally physically demanding and prone to human limitations such as hand tremors and radiation exposure. Despite the promising results, including flawless diagnostic clarity for conditions like aneurysms and arterial stenosis, the researchers
