Abstract: A method and apparatus for extracting tissue samples are disclosed herein. An example apparatus disclosed herein includes a first sidewall and a second sidewall spaced apart from the first sidewall. The example apparatus also includes a track to receive a blade between the first sidewall and the second sidewall. The track is to guide the blade to penetrate skin of a patient to a predetermined depth of invasion.
