VERTEBRA CONNECTION MEMBER AND NUT DRIVER |
摘要 |
A vertebra connection member has: a screw member that is screwed in a vertebra; a connector member that connects a rod and the screw member; a first nut member that fixes the screw member and connector member; a second nut member that prevents the loosening of the first nut member; and a fixing member that fixes the rod and connector member. The first and second nut members are formed to have a cylindrical shape; and engagement concave portions of a concave curved shape are formed in the outer peripheral surface of the nut members from the rear ends in the screw-in direction to the front ends in the screw-in direction, in the direction in which the nut members are screwed onto the second male portion.
