A surgical tool for operating within a body cavity through a small diameter opening includes a substantially rigid member which is elongated along a first axis and which has a cross-sectional dimension to fit within the opening. A head is mounted on one end of the rigid member for movement in at least one plane through an angle with respect to the first axis. An operable control member is mounted on an opposite end of the rigid member for having at least one degree of manipulability. The control member is coupled to the head member through the rigid member such that manipulation of the control member through an angle with respect to the first axis causes movement of the head member through a corresponding angle. Accordingly, the head member can be steered within a body cavity by control external to the body cavity. In some embodiments, the control member is manipulable to a second degree for actuating an actuating member mounted on the head.
