摘要： The present application relates to a rod holder (300) configured to operate in a two-stage loading manner, which allows a rod (200) to be easily received. Also, the present application relates to a minimally invasive system for spinal surgical operation, which allows a rod to be more accurately and stably received to a pedicle screw inserted into a vertebra by using the rod holder, a rod guide and a rod guide holder. The rod holder may control a gripped state of a rod with three stages: namely a first loading stage for moving back and fixing a loading unit to fixedly grip the rod; a second loading stage for rotatably gripping the rod; and a rod mounting stage for separating the rod from the rod holder. Also, the minimally invasive spine surgery system includes a pair of rod guides (500,600) connected to upper ends of a pair of pedicle screws (100) to form a moving path of the rod; a rod holder for gripping the rod; and a rod guide holder (800) for defining an insertion path of the rod holder to guide an insertion location of the rod.
