Sklar Keyes Cutaneous Punch - Keyes Cutaneous Biopsy Punch, 4 mm - 06-4144

Sklar's Keyes Cutaneous Punch is a dermal diagnostic instrument used to remove skin samples for biopsy. The round sharp end is pushed into the skin and twisted slightly to cut away a small plug of skin. The solid knurled handle provides a gripping surface for the user who controls the depth of the excision. The Keyes punch is often used in gynecological biopsies where a deeper tissue sample is useful for the pathologist.
