Abstract: The invention relates to a recalibration device (1) used during the acquisition of images of an anatomical area of a patient during robot-assisted surgery, including a body (3) made of radxoliacent material, which comprises fiducial markers (9) made of radiopaque material, said body {3) having a bearing surface (7) intended to be manually placed on a surface of said anatomical area of the patient. According to the invention, said fiducial markers (9) are arranged in a specific geometrical pattern enabling a certain detection of the positioning and orientation of the recalibration device (1) in a three-dimensional digital model built from the images derived from the acquisition of the anatomical area.

Abstract: The robotic device for positioning a surgical instrument relative to the body of a patient includes a first robotic arm with a device for rigidly connecting to at least one surgical instrument, a device for anatomical realignment of the first arm by realigning an image that is of an area of the anatomy of the patient, and a device for compensating the movements of the first arm on the basis of detected movements. One version of the device includes at least one second robotic arm having sensors for detecting inner movements of the anatomical area, and a device for controlling the positioning of the first arm relative to sensed inner movements and to the outer movements induced in the second arm.

Abstract: The present invention relates to a mechanical system for stabilization on the floor for vehicles on castors (for example a surgical assistance robot used in an operating room) that can adopt two stable states, i.e. disengaged, the vehicle resting on the castors, and activated, the vehicle being immobilized on the floor, respectively. According to the invention, the stabilization system comprises: feet for resting on the floor, movable between a first retracted position, at a distance from the floor, and a contact position ensuring the immobilization of the vehicle through mechanical friction against the floor; means for mechanically controlling said supporting feet, said control means being movable between two stable positions corresponding to the activated and disengaged states; mechanical means for transmitting the displacement of the control means simultaneously to all the supporting feet.

Abstract: Systems and methods are described herein for resurfacing bones, and in particular, for detecting and resurfacing one or more femoroacetabular impingements (FAIs). A FAI resurfacing controller may be used to perform this detecting and resurfacing of FAIs. The FAI resurfacing controller may include a bone model generator to receive bone imaging and to generate a model of at least one osteophyte and of a surface of a native bone surrounding the at least one osteophyte. The FAI resurfacing controller may include an osteophyte identifier to set a virtual 3D boundary surface between native bone surface and the at least one osteophyte. The FAI resurfacing controller may include a resurfacing navigator to generate and output a navigation file. The navigation file may include the model with the 3D boundary surface between native bone surface and the at least one osteophyte.

Abstract: The method for the automated and assisted acquisition of anatomical surfaces includes a first acquisition of the surfaces undertaken in order to create a first numerical model and a perioperative second acquisition undertaken by scanning the surfaces in order to create a second numerical model for identifying the coordinates of the surfaces. The surfaces are supported by a robotic arm; and then the models are brought into correspondence by resetting. The scanning in the second acquisition includes making a preliminary identification of the coordinates of noteworthy points on the surfaces manually, assisted by the robotic arm, and the identifying parts a the points, in order to construct a reference frame and to determine a scanning region; creating an intermediate model from the reference frame and at least one of the points; preliminary resetting the first model with the second model; and automatically scanning the determined zone.
