1. A medical device support system, comprising:
a shaft;
an extension arm having a support for a medical device and a hub at its proximal end mounted to the shaft for pivotable movement about a rotation axis of the shaft;
a free rotating ring that is rotatable about the rotation axis and is movable relative to the shaft and movable relative to the hub;
wherein the shaft includes at least one elongated peripheral cavity that defines first and second contact faces at opposite peripheral ends of the cavity;
wherein the hub is pivotably mounted for a range of at least 360° (360 degrees) rotation about the rotation axis, wherein the at least 360° (360 degrees) rotation range is based on a compound of a first rotation range and a second rotation range, wherein the first rotation range is defined by a fixed stop of the hub configured to move between first and second contact faces of a radially outward protruding member of the free rotating ring, wherein the second rotation range is defined by a radially inward protruding member of the free rotating ring configured to move between the first and second contact faces of the elongated peripheral cavity of the shaft.
