description A device for obtaining a tissue sample includes a needle body extending along a longitudinal axis from a proximal end to a distal end and including a lumen extending therethrough and a plurality of flaps coupled to the needle body via hinges. Each of the flaps is movable between a closed configuration in which a cutting end of each of the flaps extends towards the longitudinal axis of the needle body so that the flaps extend radially inward to at least partially cover a distal opening of the lumen, and an open configuration, in which the flaps are rotated about the hinges so that cutting ends thereof are moved toward an interior surface of the lumen to uncover the distal opening of the lumen and permit a target tissue to be received therebetween and into the lumen.
