Jansen-Wagner retractor is a self-retaining retractor, thus the instrument can be held in place without manually holding it. Although this device is 5″ long, it contains 5×5 sharp prongs that are able to retract thicker tissue, typically found in the abdominal cavity. Once positioned in a desired place, the retractor is able to hold the incision open so that the surgeon is able to continue the operation without any underlying tissue blocking the area.
