Abstract: A surgical treatment system comprises a drill bit extending along a proximo-distal drill bit axis suitable for drilling a hole in the pedicle of a vertebra when the bit is rotated. The bit includes, successively along the drill bit axis, a distal end, a cylindrical drill centred on the drill bit axis for drilling the hole by cutting into and removing bone material from the pedicle to give a distal end portion of the hole a cylindrical shape, and a milling cutter for cutting bone material from the pedicle of the vertebra to give a proximal end portion of the hole a funnel shape gradually widening from the distal end portion of the hole. A pedicle screw extends along a proximo-distal screw axis and is designed to be screwed into the hole by being rotated after the drill bit has drilled the hole and has been removed from this hole.

Abstract: The installation according to the invention has a practical and effective arrangement, comprising an operating table, a robot for posterior spine surgery, as well as a bridge table that comprises, in part, two uprights designed to be separated from the operating table when the installation is in use, while being arranged and rising from the ground on either side of a patient recumbent on the operating table and, in part, a support platform for the robot, this platform resting on the uprights so that, during use, it lies over the patient recumbent on the operating table and being designed, during use, to support the robot extending directly above the spine of the patient recumbent on the operating table.

Abstract: This image-processing method comprises steps of: defining, in a three-dimensional digital image of a target object, a plurality of observation directions passing through the three-dimensional digital image and emanating from a predefined observation point; for each observation direction, calculating a resulting value from the respective brightness values of the voxels of the digital image that are passed through by said observation direction; constructing a two-dimensional digital image whose pixel brightness values correspond to the calculated resulting values.
