一种后路寰椎骨折复位固定器
摘要：
本发明公开了一种后路寰椎骨折复位固定器，包括螺钉、左右布置且活动连接的左固定板和右固定板，所述左固定板的左端和右固定板的右端均设有用于安装螺钉的锥形通孔，所述锥形通孔的上端口径大于下端口径，左固定板左端的锥形通孔向右下方倾斜，右固定板右端的锥形通孔向左下方倾斜，所述螺钉在其螺钉本体上端还设有锥形结构。寰椎骨折复位固定器在固定状态下，螺钉本体的下端穿过所述锥形通孔与寰椎侧块连接，锥形结构嵌入安装于锥形通孔内，螺钉本体的直径小于锥形通孔的下端口径。本实施方式有利于提高寰椎骨折的治疗效果。
摘要（英）：

The invention discloses a posterior atlas fracture reduction fixator which comprises screws, a left fixing plate and a right fixing plate. The left fixing plate and the right fixing plate are arranged left and right and movably connected, conical through holes for allowing the screws to be mounted therein are formed in the left end of the left fixing plate and the right end of the right fixing plate, and the aperture of the upper ends of the conical through holes is larger than that of the lower ends of the conical through holes. The conical through hole in the left end of the left fixing plate inclines towards the lower right portion, the conical through hole in the right end of the right fixing plate inclines towards the lower left portion, and conical structures are arranged at the upper ends of screw bodies of the screws. In the fixed state of the posterior atlas fracture reduction fixator, the lower ends of the screw bodies penetrate through the conical through holes to be connected with atlas side blocks, the conical structures are mounted in the conical through holes in an embedded mode, and the diameter of the screw bodies is smaller than the aperture of the lower ends of the conical through holes. According to the embodiment, the treatment effect of atlas fractures can be improved.
