  • Patent number: 5287575
    Abstract: The present invention is directed towards an auxiliary hand table which is removably mounted to a main surgical table. The hand table is mounted, via first and second mounting devices, to the rails provided on each side of the main surgical table. The first mounting device includes upper and lower jaws, the upper jaw being provided with a fastener to positively attach the device to the rail. The second mounting device includes a pair of interconnected hook-shaped members which are hooked over the opposite rail. The second mounting device further includes a series of mounting studs which facilitate attachment of a hand table support structure, thereby supporting the hand table. The vertical position of the hand table relative to the main table is adjusted by altering the mounting position of the support structure to the second mounting device. A tensioning bar interconnects the mounting devices, one end of the bar being received by an elongated bore provided by the first mounting device.

  • Patent number: 4564164
    Abstract: Two metal blocks, each having a cylindrical passage containing a rod, and a slot extending from one side to the cylindrical passage, also have a hole extending across the slots. A threaded member passes through the hole in one block and into threads contained in the other block beyond the slot. A compression head is mounted on the other end of the threaded member and is provided with a handle. When the handle is turned to advance the threaded member, the slots tend to close somewhat preventing movement of the rods in the blocks. When the threaded member is withdrawn slightly, the rods can be moved to desired positions relative to the blocks and the blocks can be rotated relative to each other.
