Prof. Dr. Sprotte developed with the Sprotte^® needle the first atraumatic needle for lumbar puncture and spinal anaesthesia. The secret of its success can be found in its unique tip geometry and basic architecture. This design, developed especially for the requirements of durapuncture, enables atraumatic puncture of the ligamentary structures and optimises CSF flow while simultaneously reducing the incidence of post-spinal headaches.
