The patient's seat is a chair with adjustable back and head-rest. This chair can be moved vertically and can be inclined so that the patient is decumbent. The operator's seat is in the shape of a saddle with an adjustable back, so that the operator can sit in a fixed manner. This seat can move vertically and rotate so that the operator can sit above the patient's knees, or behind the patient, etc. The operator's seat can include a control panel, which is movable, an orientable lamp, a safety device etc. The system is designed to give both the patient and the operator more comfortable positions.
