A new surgical robot developed in China is showing promising results in brain imaging procedures. Researchers say the system can perform complex tasks faster than traditional manual methods.
The YDHB-NS01 system is a robot designed for cerebrovascular interventions. It helps doctors carry out cerebral angiography, a procedure used to examine blood vessels in the brain.
This test is essential for diagnosing and treating many brain conditions.
In a clinical study, the robot reduced procedure time by 29 percent. On average, the time dropped from 38 minutes to 27 minutes. This means doctors could complete procedures faster while maintaining the same level of accuracy.
Dr. Zhao Yuanli, the lead researcher, said, “The robot-assisted system is safe and feasible for cerebral angiography and shows performance comparable to manual methods.”

The study was conducted at Peking Union Medical College Hospital, one of China’s top medical institutions. A total of 50 patients were involved. Half underwent robot-assisted procedures, while the rest received traditional manual treatment.
All procedures were completed successfully. Both robotic and manual methods achieved a 100 percent success rate. Doctors were able to clearly visualize all target blood vessels in every case.
However, the robotic system offered clear advantages for surgeons. During manual procedures, doctors must stand close to X-ray machines and wear heavy protective gear to reduce radiation exposure. This can be physically tiring and risky over time.
With the robot, the surgeon operates from a separate room using a control system. This reduces direct radiation exposure and eliminates the need for heavy protective clothing.

Manual procedures depend heavily on steady hands. Even small tremors can affect precision. The robotic system eliminates this issue by providing stable and controlled movements.
Doctors reported that the robot enabled smooth handling of tools such as catheters and guide wires. The system also offered responsive controls and clear feedback, helping improve overall performance.
Dr. Zhao said the robot improved both safety and reliability. “It allows more stable operations and reduces the limitations of human hands,” he explained.
One of the key findings of the study was the speed with which doctors adapted to the system. With just two training sessions, the same surgeon was able to perform procedures more efficiently using the robot.
This suggests that the technology can be adopted without long learning periods, making it practical for wider use in hospitals.
The YDHB-NS01 system is China’s first approved vascular intervention robot. It is also considered the world’s first approved robot specifically designed for cerebrovascular procedures.

The system was developed in Hebei province and has already been tested in multiple medical centers. In earlier trials, it completed 257 procedures with a 100 percent success rate.
Experts believe robotic systems like this could transform how complex medical procedures are performed. By improving precision, reducing fatigue, and lowering radiation exposure, such technology can make treatments safer for both patients and doctors.
While the results are still early, they highlight the growing role of robotics in healthcare. As technology continues to improve, more hospitals may begin to rely on robotic assistance for critical procedures.
For now, the study offers a clear message: machines are not replacing doctors, but they are becoming powerful partners in the operating room.
