摘要：
A cage device includes a first support member which has a bone contact surface and from which depend side surfaces that are provided with ratchet teeth. The first support member ratchets with a ratchet member, which in turn ratchets with a ratchet wall, such that the first support member and the ratchet member are movable independently of each other and form a multiple sliding mechanical mechanism.
