Abstract
A spine fixing apparatus including: a plate fixed to a spine; screws inserted into the spine by being coupled to the plate; a rotation member for rotary motion at a predetermined location between the screws; and sliding members provided at opposite sides of the rotation member and disposed between the rotation member and the screws. The rotation member can push the sliding members such that the sliding members rectilinearly move to cover upper surfaces of the screws. The spine fixing apparatus can facilitate the locking and unlocking of the screws by switching between lock and unlock modes, and can be firmly fixed to a spine. The plate has a window that enables an operator to identify a surgical region with naked eye. The window also allows the operator to easily bend the plate into a suitable shape for a patient's spine, and closely fix the plate to the spine.
