ABSTRACT:
A surgical apparatus for removing tissue, which includes a housing, an elongated body which extends from the housing and forms an opening at a distal end, the elongated body further forming a tissue receiving cavity in communication with the opening, a cutting member operatively associated with the housing and movable transverse to the elongated body in proximity to the opening, and a tissue retaining member positioned in proximity to the opening and the cutting member, the retaining member being selectively movable from a retracted position to a deployed position, wherein when positioned in the deployed position, the tissue retaining member obstructs at least a portion of the opening at the distal end of the elongated body. A method is also provided for surgically removing tissue including the steps of positioning a tissue removing instrument including an elongated housing having a tissue receiving cavity at a distal end, a first tissue cutting surface longitudinally movable relative to the elongated housing distal end, an obturator having a sharpened distal end portion such that the sharpened end portion is positioned adjacent the tissue to be removed and a second tissue cutting surface transversely movable relative to the elongated housing, removing the obturator from the elongated housing, coring the tissue to be removed, severing the cored tissue from the surrounding tissue with the second cutting surface, and removing the severed tissue from the patient.
