  • Publication number: 20190274775
    Abstract: The invention relates to a recalibration device (1) used during the acquisition of images of an anatomical area of a p 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.

  • Publication number: 20190099222
    Abstract: This invention concerns an automated registration method and device for a surgical robot enabling registration between a first three-dimensional location system comprising an optical distance sensor and a second three-dimensional location system comprising optical acquisition means. The method comprises: a first step of intraoperative registration between the first location system and data recorded on an anatomical surface of a patient and; a second step of intraoperative registration of two three-dimensional location systems. The second registration step is performed at the same time as the first registration step by detection, by the optical acquisition means, of at least one point of a point cloud acquired by the optical sensor during the first intraoperative registration.

  • Publication number: 20180346008
    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.

  • Patent number: 10039476
    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.
