Claim Text:
1. A pedicle rod clamp device, comprising, in combination: at least an arm, an upper clamp, and a lower clamp; wherein said upper clamp is coupled to said arm and said lower clamp is coupled to said upper clamp; and a location of coupling between said upper clamp and said arm and a location of coupling between said lower clamp and said upper clamp are points along an axis; and wherein with said lower clamp coupled to said upper clamp and with said arm, upper clamp and lower clamp each disposed at a set location along said axis, said lower clamp can freely rotate relative to the upper clamp within a certain rotation and said upper clamp prevents rotation of said lower clamp beyond the certain rotation; wherein the upper clamp comprises an outwardly extending first protrusion, the first protrusion allowing the lower clamp to rotate relative to the first clamp within the certain rotation and interacting with the lower clamp to prevent rotation of said lower clamp beyond the certain rotation; wherein the arm comprises an outwardly extending second protrusion and wherein with said arm, upper clamp and lower clamp each disposed at a set location along said axis, the second protrusion allows the upper clamp to rotate about the axis relative to the arm within a certain rotation and interacts with said upper arm to prevent rotation of said upper clamp relative to said arm beyond the certain rotation.
