Definitions

  • hooks can be readily added, prior to the present invention it was not so convenient to add eyebolts, because it was necessary to install them from one or the other end of the rod.
  • the present invention was made in recognition of a need to provide some means to attach hooks or other anchoring devices to spinal rods and which can be installed between existing devices already attached to the spinal rods, and which also can be moved readily along the spinal rod during an implant procedure to place it in precisely the location desired without detaching the other devices.
  • the eyebolt is a combination of two shell-like portions of a malleable metal suitable for permanent placement in the human body.
  • the two portions have threaded bosses at distal ends thereof.
  • the two bosses combine to form a bolt on which a nut is received and advanced along the threads.
  • a central aperture through the eyebolt is brought into cooperation with an anchoring member to clamp tightly on a spinal rod with which the eyebolt is used.
  • the two threaded bosses have interfitting, and thus mating, rib and groove to establish and maintain alignment of the threads of the two bosses to facilitate reception of the nut on the bosses.
  • the eyebolt can be completely removed from the spinal rod without disturbing any other device attached to the spinal rod.
  • Fig. 2 is an enlarged fragmentary side elevational view taken at line 2-2 in Fig. 1 and viewed in the direction of the arrows and showing a hook affixed to a spinal rod with the split eyebolt according to a typical embodiment of the present invention.
  • Fig. 6 is a view taken in the same direction as Fig. 3 and showing the eyebolt being installed through the yoke of the hook and around the spinal rod.
  • the rod 14 is connected to the illustrated portion of the spinal column by hooks 21, 22, and 23.
  • the hooks may be constructed in a variety of shapes such as shown on page 6 in Figs. 6 and 7 of the Danek Surgical Technigue Manual for the TSRHTM Spinal Implant System, published by Danek Medical, Inc. of Memphis, Tennessee, on February 1, 1990. They have in common, a "three-point shear" clamp feature when combined with the eyebolt as described in that manual.
  • One such hook is shown in Fig. 4 herein, wherein the hook 22 has a hooked "shoe" portion 23 with a base "hook top” portion which has four arms and may be referred to as a two-way double yoke unit.
  • the split eyebolt would be provided with an initial configuration as shown in Fig. 6 where the base 46 comprises two generally C-shaped shells 46A and 46B of the same thickness as the standard eyebolt base 32 in Fig. 5, but joined at a narrow section 47.
  • Each shell has a threaded boss 48A on shell 46A and 48B on shell 46B.
  • These two bosses are brought together as shown in Fig. 7, they form a threaded shaft to receive the nut 36, which may be operated just as previously described nut 36 on the standard eyebolt.
  • Each of the bosses 48A and 48B has an interlock feature, a groove 49 being provided in boss 48A and a rib or lug 51 being provided in boss 48B.
  • the gap between the ends 27A and 27B at the entrance to the yoke 27 and corresponding gap at the entrance of yoke 28, are slightly greater than the diameter of the rod 14, and thus enable moving the rod in and out of the yokes. Then the threaded boss 48B of the eyebolt is inserted in the direction of arrow 54 through the yokes 31 and 29, respectively. Then the ends of the eyebolt can be brought together with the rib 51 being received in the groove 49 as the eyebolt closes around the spinal rod.
  • the spinal rod can be moved back into the yoke 27.
  • the nut 36 is installed on the eyebolt thread bosses as shown in Fig. 7 and advanced on the threads so that the face 36F of the nut abuttingly engages the outside faces of upper arm 35U (broken away in Fig. 7) and lower arm 35L, of the hook top.
  • it pulls the spinal rod tightly against the semi-circular inner face 39 of the lower arm 35L of the hook base and against the semi-circular inner face 38 (not shown in Fig. 7) of upper arm 35U as the semi-circular surface 47J at the transition 47 of shells 46A and 46B tightly engages the opposite surface of the spinal rod.
  • the material to be used with the split eyebolt of the present invention is stainless steel. However other materials could be used. It is not intended that it be opened and closed repeatedly, lest there be undue stress imparted at the location 47.
