ABSTRACT:
A device and method for performing a routine skin biopsy. In the first aspect of the invention, the device is comprised of a syringe, a detachable needle mounted on one end portion of the syringe, a biopsy punch attached to the same end portion which is accessible only when the needle is removed from the syringe, and a small pad of an absorbable sponge. The needle is removed from the syringe after a patient has been anesthetized with the syringe to expose the biopsy punch. A biopsy specimen is excised with the punch. Thereafter, a cylindrical plug is cut from the pad of absorbable sponge with the biopsy punch and implanted into the biopsy site. In a second aspect of the invention, a small cylindrical sponge is stored in the center of the biopsy punch and is implanted into the biopsy site with the syringe after a specimen has been excised with the punch.
