  • Patent number: 11645749
    Abstract: A system for determining and visualizing damage to an anatomical joint of a patient. The system is to: obtain a three dimensional image representation of an anatomical joint which is based on a medical image stack; determine damage to an anatomical structure in the anatomical joint by analyzing the medical image stack; mark damage to the anatomical structures in the obtained three dimensional image representation; obtain a 3D model based on the three dimensional image representation; and create a graphical user interface (GUI). The GUI may comprise: functionality to visualize and enable manipulation of the at least one 3D model; functionality to enable removal of the visualization of the anatomical structure from the 3D model; functionality to visualize and enable browsing of the medical image stack; and functionality to visualize the position of the medical image that is currently visualized.

  • Publication number: 20230108048
    Abstract: A system 100 or designing a surgical kit 700 for articulating surface repair in an anatomical joint of a patient is provided, which comprises at least one processor 120 configured to: determine damage to the anatomical joint; select, from a predefined set of implants having varying dimensions, the implant 300 that is the best fit for repairing the determined damage; select, from a predefined set of insert tools, the insert tool 720 corresponding to the selected implant 300; and design a contact surface 540 of a guide tool 500 to have a shape and contour that is designed to correspond to and to fit the contour of a predetermined area. This enables the use of standardized implants 300 that can be manufactured batch-wise, while still using an individualized guide tool 500 to ensure correct positioning of the implant 300. This helps ensuring that the implant will be positioned in the exact location of the determined damage.
