An adjustable height field post includes an inner shaft and an outer tube configured to receive and slidably engage the inner shaft. A clamp body is provided at one end of the inner shaft such that the field post can be securely attached to an operating table. An adjustment mechanism is incorporated into the inner shaft and the outer tube such that the height of the field post can be adjusted to accommodate various working conditions and also prevent any portion of the same from extending beyond an upper most attached post coupling. |
