Abstract
Provided is a spinal fixation device, which includes a cage which is placed between adjacent vertebrae to form a gap between the vertebrae, a middle plate which is detachably coupled to the cage, and deployment plates which are hinge-pivotably coupled to the middle plate at one side end, thereby stably fixing the cage in a correct position between the vertebrae.
Claims18
A spinal fixation device, comprising:
- a cage configured to be inserted between adjacent vertebrae and defining a gap;
- a middle plate detachably coupled to the cage;
- a plurality of deployment plates hinge coupled to the middle plate at one side end of each of the plurality of deployment plates, wherein the each of the plurality of deployment plates is rotatable to an arbitrary angle around the hinge coupling;
- and
- a closer rotatably coupled on a posterior side of the middle plate, wherein when the closer is rotated, the closer prevents the plurality of deployment plates from folding.
