ABSTRACT:
An elliptical skin biopsy punch includes a blade which creates an elliptical incision in the skin of a patient, in which the blade's profile is circular, thereby allowing the biopsy punch to be rocked back and forth during the surgical procedure. Integral depth guards are provided which prevent the blade from penetrating too deeply into the skin membrane, and which help to inform the physician when the incision has been completed. An aperture or window is provided so the physician can directly view the skin lesion while positioning the biopsy punch before the start of the incision. The upper portion of the biopsy punch has alignment marks to help in correctly positioning the biopsy punch around the skin lesion. Several different sizes of elliptical skin biopsy punch can be made so that the proper incision will be used for any particular skin lesion's size. Several different handle shapes are available for various sized lesions and various types of physician's hands. After the excision of the skin lesion, the result is a cosmetically ideal ellipse which can then be closed in a flat, straight suture line. A method for using the elliptical skin biopsy punch is also disclosed.
