  • Patent number: 11690727
    Abstract: The present disclosure relates to an artificial ankle joint tibial component and, more particularly, to an artificial ankle joint tibial component of an implant that is implanted into a body, the implant including: a body part having a contact surface in contact with a resected surface of a distal end of a tibia of a joint and a joint surface facing a joint; and a fixing part formed to extend a predetermined length upwards from the contact surface, wherein the fixing part is configured as a single body formed to extent a predetermined length upwards from the center in the front area of the contact surface and includes a wing extending to one side, and wherein the wing includes at least one posterior wing that extends at a predetermined angle relative to an AP line, thereby preventing stress from being concentrated on one wing to avoid a fracture thereof and increasing the contact area between a bone and an implant to strengthen fixing force, prevent rotation, and disperse stress, so that bone resorption aroun

  • Publication number: 20230130743
    Abstract: Proposed is an artificial ankle joint bearing element in which a contact area of the bearing element with a talus element is increased such that stress is evenly distributed during bearing movement of the bearing element on the talus element and wear of the bearing element is reduced under the same load; the bearing element has a front and a rear convexly formed to increase a contact area with a tibial element and distribute stress; and the front and rear of the bearing element are asymmetrically formed such that the rear thereof is formed to have a smaller height than the front thereof so as to facilitate the insertion of the bearing element into space between the talus element and the tibial element from an anterior side thereof during artificial ankle joint surgery.

  • Publication number: 20200197187
    Abstract: The present disclosure relates to an artificial ankle joint talus component and, more particularly, to an artificial ankle joint talus component including a joint surface in contact with an insert and a contact surface in contact with a bone, wherein the contact surface may be formed to be complementary to a resected surface of a talus so as to cover the entire resected surface, thereby dispersing stress, and reducing after-effects of surgery, such as osteolysis, heterotopic ossification, or the like.

  • Patent number: 7118174
    Abstract: An activating headrest comprises a headrest including a detecting link integrally connected to the headrest. The detecting link is pivotally mounted to a seat frame so as to be shifted when pressed by an occupant's back. A return spring is installed between the detecting link and the seat frame. A stopper means installed between the seat frame and the detecting link fixes the state of the headrest tilted in the forward and upward position to prevent the neck from being thrust backward.

  • Publication number: 20040145223
    Abstract: The present invention relates to a vehicle seat capable of effectively preventing a neck injury during a rear-end collision, the vehicle seat comprising a headrest supporting frame whose lower end is secured to a recliner, a seatback frame being elastically connected to said headrest supporting frame by means of elastic means, and a headrest adjusting bar for changing a height of a headrest, which couples the headrest with the headrest supporting frame, whereby the shock applied on the chest of a seat occupant, as well as a neck, can be significantly reduced by decreasing the acceleration of the upper body of the seat occupant.
