Innovative technology ROSA™ robotic device has been designed to increase the safety and reliability of various Neurological procedures without compromising established surgical protocols. ROSA™ is an integrated multi-application platform that offers a reliable and accurate surgical assistant. Comparable to a "GPS" for the brain, the robot can be used for any type of cranial procedures requiring surgical planning with preoperative data, patient’s registration and precise positioning and handling of instruments. To date, ROSA™ is the only robotic Assistant approved for Neurosurgical procedures in clinical use in Europe, the United States and in Canada and with the following specifications: A robotic arm with six degrees of freedom ROSA™ has a robotic arm with six degrees of freedom whose architecture replicates the movements of a human arm. This provides a very high dexterity in achieving complex surgical procedures as well as allowing for a complete freedom in the choice of trajectories. Advanced haptic capability ROSA™ has an advanced haptic capability that gives the Neurosurgeon the ability to easily guide the instruments manually and within established limits and restrictions established during in the planning stage. The surgeon is able to easily interact with the robot without changing any of his surgical techniques thus fully harvesting the benefits of a robotic movement.
