Definitions
- the present invention relates to a hinge fixing system for a spinal osteosynthesis device and more particularly to a system for fixing and immobilizing a connecting rod inside a connector or in the head of a spinal osteosynthesis device.
- a pedicle screw previously anchored in a vertebra of a spinal segment to be instrumented.
- the fastening system according to the present invention aims to avoid the assembly of parts together while allowing a simple and quick introduction of the connecting rod inside the connector or in the pedicle screw head previously anchored.
- the hinge fixing system according to the present invention is capable of being arranged on any bone anchoring means of a spinal osteosynthesis device, for example on an anchor screw head, on a screw connector. polyaxial or with hooks.
- connection connector comprising on both sides of a U-shaped opening a first and a second vertical branch cooperating respectively via rotation axes with a clamping member for translational immobilization and rotation of the connecting rod after its tilting and locking above the opening by a latch resiliently loaded by a leaf spring.
- the fastening system comprises a clamping element which is traversed in the middle of a threaded bore cooperating with a locking screw for immobilization in translation and in rotation of the connecting rod.
- the fastening system according to the present invention comprises a clamping element comprising an edge in which are formed hook-shaped notches, separated by a central and vertical groove.
- the fastening system according to the present invention comprises a connection connector whose second branch comprises in a vertical direction a groove on the one hand setting and guiding around the axis of rotation of the latch on the other hand the fastening the spring blade on which bears said latch.
- the fastening system comprises a latch which is integral, opposite a bore receiving the axis of rotation, locking fingers.
- the fastening system comprises a latch comprising a vertical flattened portion which extends inside a groove in order to retain the free end of the spring blade lying opposite to that integral with said connector. link.
- the fastening system according to the present invention comprises a connecting connector whose axes of rotation ensuring the pivoting of the clamping element and the lock are offset relative to each other.
- the fixation system according to the present invention comprises a connecting connector which is integral with a bone anchoring element consisting of a bone anchoring screw.
- the fastening system comprises a connecting connector which is integral with a bone anchoring element consisting of a hook.
- the fixation system comprises a connecting connector which is mounted on a bone anchoring element consisting of a bone anchoring screw with ball head.
- FIGS. 1 to 4 are perspective views illustrating the various constituent elements the hinge fixation system for a spinal osteosynthesis device according to the present invention.
- Figure 5 is a perspective view showing by way of non-limiting example another bone anchoring means of a spinal osteosynthesis device on which is arranged the hinge fixing system according to the present invention.
- FIGS. 1 to 4 show a bone anchoring element 1 constituted, for example, by a bone anchoring screw 2 of a spinal osteosynthesis device 3 allowing fixation and immobilization in translation and in rotation of a connecting rod 4 connecting different vertebral stages of a spinal segment of a spine to be instrumented.
- the anchoring screw 2 comprises, in the extension of its threaded portion 5, a connection connector 10 forming a connecting head 7 provided with a U-shaped opening 8 for the introduction and the passage of the connecting rod 4 .
- connection connector 10 comprises, opposite the bottom of the U-shaped opening 8, a hinged fixing system 100 which, after locking, makes it possible to clamp and immobilize in translation and in rotation of the rod. link 4 in the bottom of said U-shaped opening 8.
- connection connector 10 comprises on both sides of the U-shaped opening 8 a first and a second vertical branch 11, 12 respectively allowing the assembly about the axis of rotation 13, 14 of a 15 and a lock 16 resiliently loaded hinge fastening system 100.
- the first branch 11 of the connecting connector 10 is pierced in a horizontal direction of a through bore 17 allowing by means of the axis of rotation 13 the assembly of the clamping element 15 so that the latter can tilt around said axis rotation 13 and come close the opening 8 U-shaped.
- the clamping element 15 is pierced at one of its edges with a through-hole 18 cooperating with the axis of rotation 13 when it is assembled on the first branch 11 of the connection connector 10.
- the element of FIG. tightening 15 is traversed in its middle and in a direction perpendicular to that of the hole 18 of a threaded bore 19 cooperating with a locking screw 20.
- the clamping element 15 comprises, opposite the opening hole 18 cooperating with the axis of rotation 13, an edge in which are formed hook-shaped notches 21 which are separated by a central and vertical groove 22.
- the second branch 12 of the connection connector 10 comprises firstly in a horizontal direction a through hole 23 and secondly in a vertical direction a groove 24 allowing the introduction and guidance around the axis of rotation 14 lock 16.
- the groove 24 also allows the installation in a vertical direction of a spring blade 29, one end of which is secured to the connector 10 at the bottom level of the opening 8 in the shape of a U.
- the lock 16 is secured, opposite the bore 25 receiving the axis of rotation 14, locking fingers 26 arranged in a direction parallel to that of said axis of rotation.
- the lock 16 has on one of its edges, and more particularly that directed towards the U-shaped opening 8 of the connection connector 10, a vertical flattened portion 27 which extends at the level of the locking fingers 26 to inside a groove 28 for guiding and retaining the free end of the spring blade 29 located opposite to that integral with said connecting connector 10.
- the spring blade 29 keeps the latch 16 in one and the same position, ie in a vertical direction and parallel to that of said leaf spring 29, said locking position.
- the surgeon applies a vertical pressure F on the clamping element 15 in order to push the latch 16 towards the outside of the connection connector 10 in order to move said latch so that the latching fingers 26 of the latch can pass to the latch.
- a vertical pressure F on the clamping element 15 in order to push the latch 16 towards the outside of the connection connector 10 in order to move said latch so that the latching fingers 26 of the latch can pass to the latch.
- FIG. 5 shows another bone anchoring element 1 according to the present invention consisting, for example, of a hook 50 of a spinal osteosynthesis device 3 integral with the connecting connector 10 on which is arranged the hinge fixation 100 for fixing and immobilization in translation and in rotation of the connecting rod 4 connecting different vertebral stages of a spinal segment of a spine to be instrumented.
- the hook may be pedicular, laminar or transverse.
- the hinge fixing system 100 according to the present invention can be provided on any type of bone anchoring element such as for example on the spherical head of a bone anchoring screw so that the connecting connector 10 can rotate angularly around the latter before its immobilization in a given axial position.
