  • Method for producing knee replacement implant and implant for knee replacement
    Patent number: 10357369
    Abstract: The present application discloses a method of producing a knee replacement implant, an implant for knee replacement formed by using the method, and a knee replacement implant. The method includes: defining a hip center, a knee center, an ankle center and a posterior femoral condylar axis of a lower limb; generating femoral geometric parameters and tibial geometric parameters, the femoral geometric parameters and the tibial geometric parameters being measured in relation to the hip center, the knee center, the ankle center and the posterior femoral condylar axis; collecting anthropometric data from a defined population using the femoral geometric parameters and the tibial geometric parameters; and creating a femoral component and/or a tibial component using the collected anthropometric data.
    Type: Grant

  • Surgical robot with hybrid passive/active control
    Patent number: 8961537
    Abstract: A surgical robot with seven degrees of freedom, including various types of joints, offers a hybrid active-passive control for operation both manually and by programmed navigation. One of the degrees of freedom allows the robot to be moved efficiently around the axis of a patient's body to provide ample workspace for surgical procedures in an operating room.
