| titleOfInvention | Bionic artificial atlanto-odontoid joint |
| abstract | The utility model discloses a bionic artificial atlanto-odontoid joint including an atlas part, an axis part, and a screw, the atlas part is composed of a middle ball-socket part and a side wing, the ball-socket part is composed of a ball socket and a truncated cone arranged under the ball socket, the side wing is provided with symmetrical locking screw holes at the two sides, the axis part is divided into an upper part and a lower part, the upper part comprises a bulb at the top end and a cylinder under the bulb, the contact part of the bottom surface of the cylinder and a bone surface is in a multi-tooth structure, the lower part is matched with the front structure of an axis body, three locking screw holes are arranged in the lower part in a delta shape, and the contact parts of the joint and the bone surface are provided with hydroxy apatite coatings. On the premise of maintaining the atlantoaxial rotation function, the atlantoaxial limit lateral flexion and flexion functions are realized; and moreover, the designed depth of the ball-socket joint is deep, the dislocation risk is reduced, and the joint is more approximate to a human physiological state on bionics. |
