Abstract

An artificial vertebral body includes a housing, a rotating body and a support member; an inner peripheral surface of the housing is provided with a first cooperating portion. The rotating body is rotatably disposed in the housing, an outer peripheral surface of the rotating body being provided with a second cooperating portion; the first cooperating portion can cooperate with the second cooperating part to restrict the rotation body to only rotate clockwise or counterclockwise; the support member passes through the rotating body and is screwed together with the rotating body; and the rotating body can rotate relative to the housing to drive the support member to move along the axial direction of the rotating body.
