1. A method of incising a tissue structure comprising: capturing a tissue structure of a patient between an emitter and a receiver of an evaluation and incision instrument; determining whether an incision path through the captured tissue structure is clear of a nerve utilizing the evaluation and incising instrument; disabling axial movement of a sharpened edge of a flat cutting member of the evaluation and incision instrument based upon a determination that a nerve is within the incision path; and allowing axial movement of the sharpened edge of the flat cutting member along the incision path based upon a determination that a nerve is not within the incision path.
