Abstract
A retractor-distractor system comprising a frame with slidably coupled superior and inferior arms extending therefrom. The superior arm comprises a superior clamp arm pivotally coupled to a lateral end of the superior arm, a superior ball joint received between the superior clamp arm and the superior arm, and a superior ball joint lock operable to pivot the superior clamp arm proximate to the superior arm, thereby locking the orientation of the superior ball joint. The inferior arm comprises an inferior clamp arm pivotally coupled to a lateral end of the inferior arm, an inferior ball joint received between the inferior clamp arm and the inferior arm, and an inferior ball joint lock operable to pivot the inferior clamp arm proximate to the inferior arm, thereby locking the orientation of the inferior ball joint. The superior and inferior arms are operable to receive a modular blade to retract and distract tissue.
