摘要： A retractor comprising a first blade and a second blade, the first blade and second blade having a first blade tip and second blade tip, respectively. The first blade and second blade attach at a pivot point for allowing the first blade tip and second blade tip to move toward and away from each other to create an opening having an opening magnitude. The second blade has a ruler extension having ruler indicia, and the first blade has an arrow end opposite the first blade tip. The arrow end refers to the ruler indicia to indicate the opening magnitude of the retractor. The second blade has a handle track. A handgrip is attached to a bar which is slidably mounted in the handle track. The ruler indicia on the second blade also extends along the handle track.
