The robotic-assisted VELYS system helps surgeons to plan and perform the implantation of a knee replacement. It is equipped with optical tracking technology that identifies the relative position of the bones and instruments during the intervention. The robot with a tool arm is mounted directly to the operating table. Due to its compact dimensions, the system can be integrated into any operating theatre environment and offers the surgical team sufficient room to work. The unified design language of all components enables a consistent user experience.
