1. A surgical stabilizer arm configurable to retain tissue manipulator tools with either a shaft end or a ball end, comprising:
a cylindrical sleeve with a central cavity;
a dual actuator having a proximal end fixed in the central cavity and a distal end projecting from the cylindrical sleeve, wherein the distal end has a push surface, and wherein the dual actuator has a longitudinal passage;
a grip cage having a cylindrical base and longitudinal fingers projecting distally from the cylindrical base forming a basket to retain the ball end, wherein at least one pair of adjacent fingers defines a side opening for passing the ball end into the basket with a shaft extending from the ball located between distal ends of the fingers; and
a swage catch longitudinally slidable in the central cavity having a distal end retained by the grip cage at an interior surface of the cylindrical base, and having a proximal end adapted to be drawn by a tension cable of the stabilizer arm;
wherein the dual actuator further includes a cantilevered spring arm with a detent at a distal end which flexes in a radial direction, wherein the spring arm has an equilibrium position at which the longitudinal passage is open and a compressed position at which the detent partially closes the longitudinal passage; and
wherein the grip cage includes an interior sloped surface for compressing the spring arm to the compressed position when the grip cage is pulled toward the cylindrical sleeve by the swage catch.
