A punch biopsy apparatus has: a hollow cylinder body; a coring blade at the base of the hollow cylinder body; and a scooping blade assembly installed through a pair of installation channels and pivotally secured by a pair of pivot seats, where the scooping blade assembly comprises a semicircular scooping blade having actuating levers attached at each end via essentially rectangular connectors. This device helps minimize bleeding and minimize damage to the biopsy sample being retrieved.
