Abstract: Provided is a percutaneous screw fixing rod inserting device for minimal invasive surgery, which includes: a leg unit including a plurality of support legs, each of which has a joint link provided at a lower end thereof; an aligning holder unit configured to align the plurality of support legs such that longitudinal central axes of the support legs of the leg unit are placed on one virtual plane, the aligning holder unit holding the support legs such that an angle between the longitudinal central axes of the support legs is maintained; and a rod inserting unit coupled to the aligning holder unit to rotate by a predetermined angle around a portion coupled to the aligning holder unit and configured to insert the rod into a rod insert hole provided to the joint link of the support leg, thereby eliminating the difficulty of inserting the rod caused by the misalignment of the pedicle screws and increasing the convenience or efficiency of the medical procedure.

Abstract: Disclosed is a spinal complex cage, which includes a cage which is made of a polymeric material, and metal covers which are formed on upper and lower portions of the cage, respectively, in which couplers formed on the metal covers are coupled to coupling grooves formed in the cage, such that the metal covers are detachably coupled to the upper and lower portions of the cage. Accordingly, because the cage and the metal cover are detachably coupled to each other, the manufacturing method is simple, and the metal cover is easily coupled to or separated from the cage, such that the spinal complex cage may be variously and quickly applied even during the surgery in accordance with shapes or intervals between the vertebral bodies, and as a result, a spinal fusion rate is excellent, and the accurate and precise surgical operation is enabled.
