Abstract: A computer-assisted surgery system allows a user to control movements of a surgical tool by providing, to a control unit, inputs in the form of measured displacements via a movable part of a handle while treating a region of interest with the tool. The control unit is configured to enable motion of the tool with respect to an anatomical structure only if a user moves the movable part, receive the measured displacement of the movable part, receive from a localization unit the relative position and orientation of the tool relative to the anatomical structure, based on the measured displacement, on the surgical plan and on the relative position and orientation of the tool relative to the anatomical structure, compute an instruction to send to a motorized joint to move a robotic arm to operate the tool according to an optimal trajectory, and send the computed instruction to the motorized joint.

Abstract: A modular fluoro-navigation instrument including a base made of a substantially radiotransparent material. The base is intended to be rigidly secured to a patient's bone and a tracker rigidly attachable to the base. The instrument has a registration phantom separate from the tracker which includes a plurality of radiopaque fiducials. The base and the registration phantom includes respective attachment members for reproducibly attaching the registration phantom to the base.

Abstract: A fluoro-navigation system for navigating a tool relative to a medical image. The system includes a motorized X-ray imaging system for acquiring a plurality of images of a region of interest of a patient, the position of each image being known. Also included is a localization system, a registration phantom with a plurality of radiopaque fiducials, a tracker for being tracked by the localization system, a processor for receiving the plurality of images and for reconstructing a 3D medical image from the images using radiopaque fiducials visible in the plurality of images. Also included is base made of a substantially radiotransparent material, to be rigidly secured to a patient's bone and having a reproducible fixation system for attaching the registration phantom and/or tracker.

Abstract: The invention relates to a device for minimally invasive attachment of a tracker (20) and/or a registration phantom (30) to a patient's bone, comprising a base (10) made of a substantially radiotransparent material, characterized in that the base (10) comprises: a support surface (11) intended to face the bone, a plurality of non-parallel through holes (14) for passing a respective percutaneous pin (2) through the base (10); at least one slot (15) extending from an edge of the base (10) in a direction transversal to the through holes (14), said slot (15) passing throughout the base (10) until the support surface (11) and being intended to engage a percutaneous pin (2) implanted into the patient's bone so as to allow the base (10) to slide along said pin (2); and a reproducible fixation system for attaching the tracker (20) and/or the registration phantom (30) to the base.

Abstract: The disclosure relates to a method for disassembling a marker array (10) comprising at least three optical markers (100) arranged according a determined array geometry configured to be tracked by a localization camera from an array fixation (11) to which the marker array (10) is connected, the method comprising, prior to or during disconnecting the marker array (10) from the array fixation (11), actuating a mechanism configured to selectively modify the array geometry so as to unable tracking of the marker array by the localization camera.
