1. A retraction system for separating tissue, comprising:
a first retraction blade including:
a retraction blade portion having a proximal region and a distal region, the retraction blade portion extending along a longitudinal axis between the proximal and distal regions;
a first rod-shaped portion extending away from the distal region of the retraction blade portion on a first side of the longitudinal axis of the retraction blade portion, the first rod-shaped portion having a diameter corresponding to a rod-receiving channel of a pedicle screw as used in spine surgery;
a second rod-shaped portion extending away from the distal region of the retraction blade portion on a second side of the longitudinal axis of the retraction blade portion, the second rod-shaped portion having a diameter corresponding to the rod-receiving channel; and
a ratchet mechanism operatively associated with the second rod-shaped portion, the ratchet mechanism being adapted to allow the second rod-shaped portion to move with respect to the first rod-shaped portion, thereby changing a distance between the first and second rod-shaped portions.
