The robot Rosa is a robot for stereotaxis. That is to say, like a GPS, it will allow us to locate ourselves in the brain. And we're going to be able to hit a target, even a deep one, without making a mistake . For Professor Pierre Kehrli, head of the neurosurgery department, the Rosa robot, which has just entered into service at Strasbourg Hautepierre University Hospital, is a definite advance, especially for children. "It saves imaging and handling time. »
And the practitioner notes: "Before Rosa, you had to work with a very heavy stereotactic frame, attached to the patient's head. It was often very frightening for the patient, and impossible to use in children or psychiatric patients. "With the robot, you don't need a frame anymore. "The patient enters the OR asleep, without stress. We've been able to place electrodes in children, even very young children. »
For example, a 22-month-old baby with very severe epilepsy was able to benefit from this technique. "This enabled us to perform the smallest EECG (electroencephalogram) here in Strasbourg," says Kehrli.
Every month, the robot helps to place deep electrodes in a patient. Deep areas of epilepsy or areas that are difficult to identify by radiology need to be explored," notes Dr Anne de Saint-Martin, a neuropaediatrician. We are lucky to have this synergy of technical means and platforms grouped together in the same place, which is quite unique in France. »
Rosa is also used to perform biopsies or endoscopic surgery. With the robot, the deep areas of the brain that cause epileptic seizures can be operated on more safely. "This will help restore developmental functions in children, says the neuropaediatrician, especially in younger children who are in decline due to repeated and destructive seizures. »

In the near future, Dr. Kehrli would like to use this technology for patients with Parkinson's disease. And by 2017, he plans to couple the robot to imaging "to control the trajectories of the electrodes or biopsy needles during the procedure. "In the meantime, all Alsatians will be able to benefit, if necessary, from the new Strasbourg platform. As for children, "all those who need to undergo cranial surgery are operated on in Strasbourg".
The Rosa surgical robot cost over €310,000. The pension group Arpège financed more than half of this cost, by signing a cheque for €175,000. The total cost of the equipment, including maintenance, amounts to €500,000, spread over five years. The Rosa device integrates, under a single platform, preoperative planning software, navigation functions, robotic technology for handling surgical instruments and advanced visualization features.
