A surgical punch (R) for cutting body tissue comprises an axially elongated support (6) having first and second end portions; first and second cutting jaws (16, 18) operably associated with the first end portion and movable between an open position and a closed position relatively toward and closely past each other in tissue-severing shearing action; an actuator operably associated with the second end portion for providing relative motion between the first and second jaws; and a plurality of upstanding blades (30) disposed within the opening (28) for dividing the opening into a plurality of smaller openings (36). The first jaw has the opening (28) adapted to receive the second jaw in tissue-severing action in the closed position. The second jaw cooperates with the blades when in the closed position, thereby to cut the tissue into smaller fragments substantially corresponding to the sizes of the smaller openings.
