A device for selectively grasping and cutting tissue includes an outer tube having a longitudinal axis and an open proximal end and an open distal end; also an inner tube within the outer tube, the inner tube having a longitudinal axis and an open distal end and an open proximal end; as well as a cup-shaped cutting member mounted to the distal end of the outer tube, the cutting member being larger in diameter than the diameter of the outer tube, the cutting member including one or more cutting surfaces around the lip of the cup-shaped cutting member, the one or more cutting surfaces facing in a distal direction; also, a cylindrical cup-shaped cutting member mounted to the distal end of the inner tube; the cutting member including one or more cutting surfaces mounted around the lip of the cylindrical cup-shaped cutting member facing in a proximal direction; and, the inner tube is of a diameter to be slidably movable within the outer tube; whereby moving the inner tube alternately in distal and proximal directions along the longitudinal axis causes the one or more cutting surfaces of the inner tube to approach and distance themselves from the one or more cutting surfaces of the outer tube, and, whereby tissue situated between the inner tube and the outer tube is grasped and cut.
