A tissue retractor device for retracting tissue is disclosed. The device includes a base connected to a plurality of blades distributed around the base. Each of the blades is outwardly movable from the base. A pusher is engaged to the base. The pusher is movable in a longitudinal direction to move the blades to angularly displace each of the blades from a respective closed position to an open position. At least one biasing device is engaged with the base that biases the respective ones of the blades toward a closed position. The closed position is where the blades are relatively close together with respect to the open position.
