ABSTRACT:
Disclosed is a spine fixation apparatus, more particularly, a pedicle screw implanted into a spine and an operating device for the pedicle screw capable of easily inserting a rod to a head section of the pedicle screw in order to securely fix the spine. The pedicle screw has a head section including a recess part defined by first and second sidewalls, a screw section, and a support unit formed at an upper portion of the recess part of the head section while connecting the first sidewall to the second sidewall. The operating device has a screw coupling rod having an elongated pipe shape, a body having a first side coupled to the screw coupling rod, a rotating member having a first end coupled to a second side of the body in such a manner that a second end of the rotating member rotates about the first end thereof, and a rod receiver coupled to the second end of the rotating member. Due to the support unit, the rod is prevented from being easily separated from the pedicle screw, thereby facilitating minimum incision surgery. The operating device for the pedicle screw allows an operator to easily perform minimum incision surgery while making several incisions for the pedicle screws and the rod in the back of the patient and keeping the size of incisions quite a small.
