A surgical device for excising a tissue sample from a patient. The device includes a pair of articulable plates having blades mounted thereon. A collar is axially moveable along a rotatable actuating member such that the collar induces axial movement of the plates. Cam surfaces cause the plates to move radially inward toward one another, thereby bringing the blades toward one another so as to cut the tissue sample from the patient. |
