<p>Stereotaxis system for surgery of the rachis which allows to localise and approach anatomical points and comprising a mechanical device having three and two degrees of freedom for displacement, in the first place, longitudinally, transversally and in elevation with respect to the operation table and, in the second place, a rotation with respect to the sagittal plane and a final introduction towards the target point which the surgeon wants to operate. To this effect, and in order to localise the point of intervention, the system uses sights adaptable to the X ray apparatus and which allow to determine with high precision the spatial coordinates of the target point which is desired to be operated.</p> |
