Exploring the Capabilities of 5G for Remote Surgery: Current Challenges and Future Possibilities

Published on: Mar 10, 2023 Robotic surgery is a way of performing surgical procedures with the help of robotic systems. A surgeon, instead of directly using the required operating tool (e.g. scalpel), remotely makes use of devices that have hand-like movements and perform the procedures for him. These special robots, also called telemanipulators or remote manipulators, are robotic arms consisting ...
