Abstract
An apparatus and method for precisely marking a surgical incision. A surgical knife contains a cutting blade which terminates proximally with a flat shoulder that is perpendicular to the cutting edge and contains a bioreactive stain dried thereon. In use, the surgical knife is inserted by the surgeon into the tissue of interest, up to the shoulder. The shoulder is then briefly placed against the incised tissue until the stain is rehydrated. The stain is then drawn from the knife to the tissue by capillary action, thus marking the site of the incision.
