| titleOfInvention | Rigid extension sheet and pedicle screw |
| abstract | The invention relates to a rigid extension sheet and a pedicle screw, which comprise a screw seat, an extension sheet connecting mechanism and a ball head screw, wherein the screw seat is assembled and connected with the ball head screw, and the innovation points are as follows: the two rigid extension pieces are oppositely arranged on two sides of the nail seat and are detachably connected with the nail seat through an extension piece connecting mechanism; the screw thread groove is formed in the inner wall of the rigid extension piece along the length direction of the rigid extension piece, a limiting flange is arranged at the notch of the screw thread groove of the rigid extension piece, a screw thread piece is arranged in the screw thread groove of the rigid extension piece and is in sliding fit with the screw thread groove of the rigid extension piece, and the screw thread piece on the rigid extension piece is detachably connected with the screw seat through an extension piece connecting mechanism. The invention not only can self-adaptively adjust the lead of the same thread, but also is not easy to generate thread dislocation when being assembled with the nail seat. |
