clamp on the vertebral column rod in the installed state the transverse bridge has a connection part with a frame for receiving a first branch connected to one clamp and with a ball rotatably mounted in the frame and having a second branch pass therethrough that connects to another clamp application_number US 201213493069 A description referring now to the figures of the drawing in detail and first particularly to fig1 and 2 thereof there is shown a rod connector 2 or rod to rod connector 2 which is mounted on two vertebral column rods 4 a b the rod connector is made principally in three parts and comprises two brackets 6 a b and a connection part 8 by means of the latter the brackets 6 a b are variable in terms of their spatial position relative to each other in several degrees of freedom and can be fixed relative to each other in a desired spatial position each of the brackets 6 a b has a longitudinally extending branch 10 on the respective one end 12 a of which a clamp 14 is arranged the respective other end 12 b of the branches 10 lies beyond the connection part 8 i e the branches 10 pass through the latter in other words the branches 10 are directed toward each other and overlap each other the branches 10 thus form together with the connection part 8 a transverse bridge 11 which fixes the location of the two clamps relative to each other each clamp 14 is made up of a clamping jaw 16 and.
