  • Publication number: 20240115294
    Abstract: An external fixation system may include first and second fixation rings and a plurality of adjustable length struts. Each adjustable length strut may have two joints, a rod, a tube, and an actuator configured to drive the rod axially relative to the tube to change an effective length of the strut. The system may include a plurality of controller modules each configured to couple to a corresponding strut. The external fixation system may have a manual mode of operation in which the controller modules are not coupled to the struts, and manual actuation of the actuators changes the effective lengths of the struts in discrete length increments. The external fixation system may have an automated mode of operation in which the controller modules are coupled to the struts, and automated actuation of the actuators changes the effective lengths of the struts in infinitesimally small length increments.

  • Publication number: 20240099738
    Abstract: A cutting assembly in which an inner tube is rotatably disposed within an outer tube and defines as aspiration path. The inner tube may include segments, and the segments may define a flexible region associated with a bend of the outer tube. The outer tube may define irrigation channels, and further define irrigation apertures positioned proximal to a cutting window or distal to the flexible region. The irrigation channels fluidly separate the aspiration lumen from an irrigation path so as to prevent ingress of irrigation fluid into the aspiration lumen through slots defined by the segments. An inner jacket may be coaxially disposed within the inner tube and configured to provide a seal between the aspiration path and the irrigation path. A distal end of the inner jacket may be disposed in a counterbore, and the proximal end of the inner jacket may be proximal to the inner tube.

  • Publication number: 20240104727
    Abstract: A computer-implemented technique for a user-specific selection of a machine-trained model for determining an implant-related parameter. A set of different machine-trained models is provided. Each model is indicative of a dedicated implant-related parameter for a dedicated patient anatomy. The method may include receiving first patient image data indicative of a patient anatomy in which an implant is to be placed, and applying at least one first model from the set of models on the first patient image data to determine an implant-related parameter. The determined implant-related parameter is suggested to a dedicated user, and feedback is received from the user on the suggested implant-related parameter. The user feedback includes one of a confirmation of the suggested implant-related parameter and an adaptation thereof. At least one second model from the set of models that is to be applied on second patient image data may be selected, based on the user feedback.

  • Publication number: 20240104747
    Abstract: A method, computer program product, device, and tracking system for assigning marker identities to markers of a tracker are provided. The tracker includes a reference detectable in a visible light spectrum, and the markers are detectable at least in an infrared light spectrum. The markers are arranged in a pre-determined relationship relative to the reference and the pre-determined relationship is indicative of the marker identities. A method implementation includes receiving first image data of the markers captured in the infrared spectrum. The method further includes receiving second image data of the reference captured in the visible light spectrum. The first and second image data may be captured under at least essentially the same viewing angle. The method further includes assigning the marker identities to the markers determined in the first image data based on the reference determined in the second image data and the pre-determined relationship.
