Abstract
A blade extending tower is provided for setting blade depth on retractors having telescoping or extending blades. The blade extending tower features a base, a column extending from the base, and mating features on the column configured to engage the blades of a retractor to extend the blades to a desired blade depth. Blade depth of the retractor is set buy sliding the retractor onto the blade extending tower such that the mating features of the blade extending tower engage the blades or the retractor, stopping the blades progression while the rest of the retractor continues along the length of the column. Thus the blades of the retractor are extended from the retractor to a depth determined by the configuration of the blade extending tower.
