Hospital da Luz Arrábida is already using, in spine and brain surgeries, the Brainlab navigation device , the most advanced neuronavigation equipment , which allows higher precision approaches and less invasive interventions. The first surgeries with this device are already being done, successfully, by the teams of Maia Gonçalves (Orthopaedics) and Mário Gomes (Neurosurgery). This acquisition occurs in the scope of Hospital da Luz Arrábida investment in technological development and improvement of its services . The Brainlab navigation technology: Is used to plan and carry out interventions, such as tumour resection, brain biopsy and screw insertion in the spinal cord , with higher precision; Allows to monitor the surgery via imaging (in a similar way to a GPS navigation system), providing the surgeon with constant visual information. The advantages are multiple, namely: Allows higher precision, in conventional open surgeries, as well as in minimally invasive surgical techniques, thus helping the surgeon to perform more accurate and effective interventions; Allows to carry out minimally invasive approaches; Helps to avoid critical structures; In spine surgery, enables a more precise insertion of implants; May reduce the percentage of re-interventions; Minimizes the need of constant use of X-ray intraoperative imaging systems, reducing the exposure of the surgical team to radiation; Reduces the risks and recovery period for the patient.
