  • Mechanical ligament balancing devices
    Patent number: 11950820
    Abstract: A device including a first plate configured to interface with a first bone structure of a joint; a second plate configured to interface with a second bone structure of the joint opposite the first bone structure; and at least one mechanical actuation mechanism disposed between the first plate and the second plate and configured to apply a distraction force along an axis between the first plate and the second plate so as to urge the first plate and the second plate away from one another, wherein the device is configured so as to have a range of motion ranging from a minimum distance between the first plate and the second plate to a maximum distance between the first plate and the second plate, and wherein the mechanical actuation mechanism is configured such that the distraction force is substantially constant distraction force across the range of motion.
    Type: Grant

  • MECHANICAL LIGAMENT BALANCING DEVICES, KITS, AND METHODS
    Publication number: 20230329876
    Abstract: A device including first plate configured to interface with a first bone structure of a joint; a second plate configured to interface with a second bone structure of the joint; and at least one mechanical actuation mechanism disposed between the first plate and the second plate and configured to apply a distraction force so as to urge the first and second plates away from one another, wherein the at least one mechanical actuation mechanism includes first and second actuation sub-mechanisms configured to provide first actuation and second sub-mechanism distraction forces that are antagonist to one another; wherein the device has a range of expansion ranging from a minimum distance to a maximum distance between the first plate and the second plate, and wherein the first actuation sub-mechanism distraction force and the second actuation sub-mechanism distraction force combine to provide the distraction force that is substantially constant.
