  • Motor-driven fixator to apply micromotion to fracture site to accelerate bone healing
    Patent number: 12220154
    Abstract: Devices and methods for treating bone fractures involving a micromotional unit (6) that produces reciprocating displacement between two fracture fragments (1) to thereby apply controllable micromotion to a fracture site.
    Type: Grant
    Filed: December 11, 2020
    Date of Patent: February 11, 2025
    Assignee: THE UNIVERSITY OF HONG KONG
    Inventors: Weichen Qi, Xiaoreng Feng, Ka-Li Leung
  • NON-CONTACT, NON-RADIATION DEVICE THAT ACCURATELY LOCATES MULTIPLE IMPLANTS IN A PATIENT'S BODY
    Publication number: 20240423496
    Abstract: A system and devices provide for accurate localization of orthopedic implants based on magnetic tracking approach (MTA) technology and without radiation. The system includes at least one magnetic beacon that is joined to an orthopedic screw/implant fixed to a patient's spine. A detector in the form of a magnetic sensor array detects the magnetic field from the beacon and produces an electrical signal in response thereto. A computer using a multi-objective magnetic location algorithm tracks the spatial position and movement of the beacon based on the electrical signal, and hence tracks the patient's spine.
