Doctors at a hospital in southern Russia have conducted what they say is Europe’s first surgery with the help of exoskeletons, the state-run lender Sberbank announced on Monday.

ExoChair, developed with help from Sberbank’s robotics division, is designed to support the lower limbs and pelvic region to help reduce fatigue and improve efficiency among workers who stand for prolonged periods of time.

The exoskeleton was used by doctors during a 12-hour urological surgery at the Second Regional Clinical Hospital in Russia’s southern city of Rostov-on-Don, the hospital said.
