In April 2025, Sony unveiled a prototype of a microsurgical robot capable of performing incredibly delicate tasks — such as stitching an incision on a single grain of corn.
This experiment demonstrates the robot’s potential in the field of supermicrosurgery, where operations involve working with vessels and nerves less than 1 millimeter in diameter.
The robot is equipped with a low-latency remote-control system that allows the surgeon to operate it using highly sensitive, pen-like controllers, while observing the procedure through a stereoscopic 4K 3D camera.
A unique feature of the system is its ability to automatically switch between instruments, minimizing tool change times and significantly enhancing surgical efficiency.
According to Dr. Hisako Hara, the robot moves exactly as she intends, creating a seamless sense of integration between the surgeon and the machine.
The prototype has already been successfully tested in animal surgeries, and Sony plans to continue its development with the goal of real-world medical applications.
This breakthrough could dramatically expand the capabilities of surgeons, reduce their workload, and improve the precision of surgeries — especially critical amid the growing shortage of medical professionals.
