Justia Patents In Aperture Of SupportUS Patent for Bone fixing system Patent (Patent # 10,512,486)
Nov 30, 2017 - Zimmer Spine
The spine is formed of superposed vertebrae, normally aligned along a vertebral axis, from the lumbar vertebrae to the cervical vertebrae, each having an anterior part, which is the vertebral body, and a posterior part, which is the vertebral arch (or neural arch), the anterior and posterior part, enclosing the vertebral foramen. Each vertebral arch is formed by a pair of pedicles and a pair of laminae, and transverse processes and/or a spinous process (or neural spine) project therefrom. The transverse processes and the spinous process project opposite to the vertebral foramen.
According to the above method, the elongate member may be fastened to the main b before fastening the rod portion to the main body, or vice-versa.
FIG. 10 is a sectional view of the bone fixing system of FIG. 9; along the plane X-X;
a conformable elongate member 7, such as a ligature, having a first free end portion 7a, a second free end portion 7b, and an intermediate portion 7c therebetween, said intermediate portion 7c being adapted to surround the bone e.g. the transverse process TP);
In the example the third and fourth internal passages 43, 44 extend, respectively, along third and fourth axis A, A′, each of the third and fourth axis forming with respect to said first axis Z an acute angle C which is preferably comprised between 0 and 70.degree. Thus, it is easier for the physician to pull on the ends 7a, 7b of the elongate member 7 for tensioning it.
On the other hand, the clamping surfaces 14c, 12c of the compression member 14 and of the main body 12 define between them fifth and sixth passages 53, 54 extending, respectively, along fifth and sixth axis B, B′, each of the fifth and sixth axis forming with respect to said first axis Z an obtuse angle D.
In both examples of FIGS. 6 and 7, the screw shaft 252b, 352b passes through the through hole 251, 351 of the bottom wall 250, 350 of the main part 212a, 312a and through the second internal passage 222, 322 and engages with the compression member 214, 314. On FIG. 7, it engages directly with the compression member 314, whereas on FIG. 6, it engages indirectly with the compression member 214, via the screw 226.
first fastening device or means for fastening a portion of the rod 5 to main body 412, 512, 612, 712; and
In the systems of FIGS. 8-12, the first fastening device or means for fastening a portion of the rod 5 to the main body 412, 512, 612, are the same as those of FIGS. 1-4 and, therefore, do not need to be described again.
In the example of FIG. 8, the compression member 414 is provided with a thread 414d for rotative engagement with another thread 412a provided on the main body 412, so that the free end portions 7a, 7b of the elongate member 7 may be clamped between a compression part 412e of the main body 412 and the compression member 414 by threadably moving the compression member 414 relative to the main body 412.
In the example of FIG. 9, the compression member 514 is also a nut provided with an internal thread 514d (see FIG. 10), and the main body 512 is also provided with an external thread 512a, but in this case, the compression member 514 is not in direct contact with the elongate member 7. Indeed, the compression member 514 cooperates with two profiled rotating pieces 515 which are rotatably mounted (around the axis in recesses 512i provided on the lateral faces of the main body 512. When the compression member 514 moves along the main body 512, it pushes the rotating pieces 515 in the recesses 512i, and each free end portion 7a, 7b of the elongate member is clamped between a rotating piece 515 and the bottom wall of the recess 512i.
In the example of FIG. 13, the first fastening device or means comprise a seat part 766 for receiving a portion of the rod 5, the seat part 766 facing the intermediate portion 7c of the elongate member 7, said portion of rod 5 being clamped between the seat part 766 and the intermediate portion 7c of the elongate member by tightening the elongate member 7 (i.e. by pulling on the free end portions 7a, 7b of the elongate member 7). Preferably, the seat part 766 is a clip for holding the rod 5. For instance, the seat part 766 is delimited by two open arms 763 with certain elasticity, said arms 763 partially surrounding the rod 5.
a main body extending along a longitudinal axis from a first end to a second end thereof, the main body comprising a groove disposed therein that extends at least partially around a periphery of the main body, and a passageway extending from the first end towards the second end of the main body, the passageway being configured to receive a rod therein;
a compression member at least partially engageable with the groove of the main body to secure the first free end portion and the second free end portion therebetween; and
a fastener engageable with the main body to secure the rod within the passageway.
2. The system of claim 1, wherein the compression member comprises a circular ring with open ends.
3. The system of claim 1, wherein the compression member comprises a fastening collar.
4. The system of claim 1, wherein the fastener comprises a threaded fastener.
5. The system of claim 4, wherein the main body further comprises threading disposed in the passageway engageable with the threaded fastener.
6. The system of claim 1, wherein the groove is transverse to longitudinal axis of the main body.
7. The system of claim 1, wherein the groove extends completely around the periphery of the main body.
8. The system of claim 1, wherein the first free end portion and the second free end portion are clamped between an inner surface e of the compression member and at least a bottom surface of the groove.
9. The system of claim 1, wherein the fastener has a socket disposed in an upper surface for receiving a driver.
10. The system of claim 9, wherein the socket comprises a hex socket.
11. The system of claim 10, wherein the driver comprises an Allen driver.
12. The system of claim 1, wherein the rod is securable within the passageway with the fastener independently of securing the first free end portion and the second free end portion with the compression member.
13. The system of claim 1, wherein the intermediate portion of the conformable elongate member extends from the main body in a direction transverse to a longitudinal axis of the rod.
14. The system of claim 1, wherein the intermediate portion of the conformable elongate member forms a loop extending away from the main body, the loop for surrounding the bone.
15. A system for securing a bone to a rod, comprising:
a main body extending along a longitudinal axis from a first end to a second end thereof, the main body comprising a groove disposed therein that extends around a periphery of the main body and two upwardly extending arms, wherein the upwardly extending arms define a passageway extending from the first end towards the second end of the main body, the passageway for receiving a rod therein;
a compression member engageable with the groove of the main body to secure the first free end portion and the second free end portion therebetween; and
16. The system of claim 15, wherein the compression member comprises a circular ring with open ends.
17. The system of claim 15, wherein the compression member comprises a fastening collar.
18. The system of claim 15, wherein the fastener comprises a threaded fastener.
19. The system of claim 18, wherein the main body further comprises threading disposed in the passageway engageable with the threaded fastener.
20. The system of claim 1, wherein the groove is transverse to longitudinal axis of the main body.
