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.

A surgical tool for operating within a body cavity through a small diameter opening while being manipulated from outside the body cavity comprising a substantially rigid member, having a proximal end and a distal end, being elongated along a longitudinal axis and having a cross sectional dimension to fit within said opening, a head member mounted on and extending axially from, the distal end of said rigid member for movement in at least one plane through an angle with respect to said longitudinal axis, an operable control member mounted extending axially from the proximal end of said elongated member for having a first degree of manipulability and coupled to said head member through said rigid member such that manipulation of said control member through an angle with respect to said longitudinal axis causes movement of said head member through a corresponding angle whereby said head member can be steered within a body cavity by control external to said body cavity, and an actuable operating device fixed to said head member, said operable control member having a second degree of manipulability for actuating said actuable operating device, said control member being independently coupled to said actuable operating device at said head through said rigid member for actuation of said actuable operating device which is unrestricted and unaffected by manipulation of said control member in said first degree of manipulation of said control member in said first degree of manipulability.
