Definitions
- the present invention relates to orientable fixing devices for the straightening and shoring of a bone system.
- the technical sector of the invention is the field of the manufacture of osteosynthesis implants.
- the main application of the invention is the straightening and propping up of a spine called a spine, of man or even possibly of animal. These two operations are necessary inter alia in the event of a fracture of the vertebrae or in the event of deviation of the spinal column resulting for example from scoliosis, kyphosis or disc disease.
- the problem posed is to produce an orientable fixing device, for the straightening and shoring up of the bone system, ie essentially the spine such that one can orient in as many directions as possible and with an angle of at least 10 ° in each direction, the connecting rod with respect to each anchoring system fixed to the bone, and this with a clamping element of the connecting rod which is offset thus allowing the choice of the placement of the rod on one side or the other of the axis of the anchoring system and reduce the overall height and thus bring the connecting rod closer to the bone to be straightened and propped up, while ensuring effective and lasting immobilization of all the mobile elements relative to each other after tightening and allowing not only a quick and simple assembly but also an easy adjustment of each part of the assembly.
- an orientable fixing device comprising at least one anchoring element having at least one part capable of being fixed relative to the bone, a head forming a boss and a crown intermediate between said anchoring element. and said boss; a clamping means, adapted to immobilize in a hole disposed laterally with respect to said head a connecting rod between several fixing devices, has a compatible bore to be threaded on said head until it comes to bear against the intermediate crown; blocking means, adapted to bear against said clamping means, is fixed to the end of the head; according to the invention: - the bearing surface of the locking means against said clamping means is of spherical hollow shape and the bearing zone of said intermediate crown against this clamping means is an inner circular edge of this crown.
- this edge which is preferably sharp, is to punch the external surface of the corresponding clamping means: this incrustation which will be called “impaction” makes it possible to obtain an effective immobilization between the clamping means and the element of anchoring after blocking.
- this incrustation which will be called “impaction” makes it possible to obtain an effective immobilization between the clamping means and the element of anchoring after blocking.
- the intermediate crown in the spherical part of the clamping means, it can be manufactured with a metal having a lower hardness and / or elastic limit than that of the material of the intermediate crown (for this type of medical application, we mainly use titanium or stainless steel);
- said tightening means is composed of at least two separable parts each comprising a half collar each forming a kind of stirrup and together said tightening hole of the connecting rod, and a part forming a kind of washer according to said bore and whose outer bearing surface is spherical in shape compatible with corresponding support forms of the intermediate crown and of the locking means and capable of allowing the orientation and the angulation of said tightening orifice of the connecting rod, of at least 5 ° and even 10 ° in all directions with respect to to any axis orthogonal to that of said boss.
- the two said separable parts are identical; they comprise on at least part of their facing surfaces bearing against one another, at least respectively a hollow female part and a protruding male part compatible and cooperating with each other for interlocking in order to position and to immobilize the two parts relative to each other.
- the end of the head of the anchoring element has an imprint capable of cooperating with any screwing tool, which makes it possible to maintain said anchoring element during the positioning of the locking means. (this can be a self-locking nut and screwed onto said head) thus avoiding exerting forces on the assembly which would be traumatic for the patient and detrimental to the solidity of the anchoring relative to the bone.
- any screwing tool this can be a self-locking nut and screwed onto said head
- an angulation of the rod relative to the anchoring system in all directions which can go for example up to at least plus or minus 10 ° relative to a plane perpendicular to the axis of attachment of the anchoring element, and 360 ° in this plane as well as relative to the axis of the rod on itself.
- the lateral "stirrup" arrangement of the clamping means ensuring the maintenance of the connecting rod makes it possible to bring the latter as close as possible bones that we want to align: this is due not only to the very design of such a stirrup system, but also to the possibility of rotation by lowering said stirrup as far down as possible.
- Said clamping element or lateral bracket being produced in two parts which are put in place one before the rod and the other after the latter, allows an implementation of all the elements with respect to one another simple chronological manner and an adjustment not requiring in most cases the bending of the connecting rod; this reduces the intervention time and avoids weakening all the mechanical parts.
- FIG. 1 is a perspective view showing three orientable fastening devices according to the invention and connected by a common connecting rod for the straightening and shoring of a spine.
- Figure 2 is a perspective view of a fixing device according to the invention mounted with a connecting rod.
- Figure 3 is a sectional view along the plane (Y Y ', ZZ') of Figure 2.
- Figure 4 is a perspective view of the different separable parts of Figure 2 before assembly.
- FIG. 1 There is shown in Figure 1 three straightening and shoring devices of a spine 2 as described in Figures 2 to 4 and connected by a smooth rod, or not, connecting 4.
- the spine 2 is generally supported by two identical sets and systems placed parallel and on each side of the backbone 2a.
- Each assembly therefore includes fixing devices shown here with anchoring screws 5 on the lateral processes 2b of each vertebra 2c.
- Such an assembly thus relieves the 2d intervertebral discs and can be used to correct the spinal deformities 2 such as kyphosis, scoliosis or disc disease.
- Each orientable fixing device comprises in a known manner at least: - an anchoring element 1 having at least one part 5 capable of being fixed relative to the bone, a head 3 forming a boss of axis ZZ 'and between the two an intermediate crown 9,
- a clamping means 8 able to immobilize in a hole 10, disposed laterally with respect to the axis ZZ 'a connecting rod 4 of axis XX' between several fixing devices and comprising a bore 11 compatible to be threaded on said head 3 until it comes to bear against the intermediate crown 9,
- the surface 6 j of support of the locking means 6 against said clamping means 8 is of hollow spherical shape and the bearing zone 9 1 of said intermediate ring 9 against this clamping means 8 is an inner circular edge of this ring which can be the inside edge of the end of a section cylindrical (with a height of the order of 0.1 to 0.4 mm for example for device dimensions as indicated in the description below) and which surrounds the cavity 9 2 in which the part can rotate spherical clamping means 8 which is housed there as described below.
- Said locking means 6 and said intermediate ring 9 therefore take up the clamping means 8 which is, for its part concerned as described below, of spherical shape symmetrical with respect to the axis ZZ 'of the head 3: thus during the final tightening of the locking means 6 there is an impact of the entire perimeter of the edge 9 X of the intermediate crown 9 on the spherical part of the tightening means 8 thus ensuring complete immobilization between these two parts in the chosen position.
- Said clamping means 8 is itself composed of at least two separable parts 8 1 ⁇ 8 2 each comprising a half-collar 12 l 5 12 2 together forming said orifice 10 for tightening the connecting rod 4 and a part each forming a washer 13 ls 13 2 following and constituting said bore 11; the external support surfaces 14 ⁇ 14 2 of these "washers", against the corresponding support forms respectively 9 1; of the intermediate crown and 61 of the blocking means are therefore spherical in shape compatible with these support forms with which they are therefore in contact and cooperate with them by being able to rotate 1 in the manner of a ball joint during adjustment of implementation.
- the outer perimeters of said surfaces 9, and zone (y ⁇ of support of the locking means 6 and of said intermediate ring 9 are spaced from each other in leaving a peripheral opening "a" around the axis ZZ 'of the head 3 and through which can therefore be rotated 360 ° relative to this axis ZZ', the two said separable parts 81, 8 2 forming the means tightening the connecting rod 4: the part 19 connecting the half-collars 12 1 ( 12 2 with the washers 13 t, 13 ?
- this angle may be more important if the outer perimeter of the surface 9 1 ⁇ and of the zone 6j of ap pot then increasing the distance a, to the detriment however of the surfaces and support zones, which can however be compensated by increasing the diameter of the spheres.
- the diameters of the internal bores 11 of the parts forming washers 13 ls 13 2 of the separable parts 8 1; 8 2 are greater than the external diameter of the part of the anchoring head 3 which they surround, leaving a clearance 15 between them, symmetrical in revolution when the axis XX 'is orthogonal to the axis ZZ', and asymmetrical well heard until even canceled by contact of the parts with respect to each other when the angle ⁇ and / or ⁇ reaches its maximum.
- the bottom of the half-collars 12 j may include ridges, threads or other roughness to increase the adhesion of the rod 4 against the walls of the orifice 10 which they constitute, and
- their facing surface and coming to bear against one another comprise at least respectively a hollow female part and a protruding male part 14 compatible and cooperating with each other by interlocking preferably at the level of their half-collar portion 12 l 5 12 2 .
- the two said separable parts 8,, 8 2 are identical so that they can be used either as a lower part or as an upper part and can be mixed without the operator needing to choose an upper or lower part; this is perfectly achieved thanks to the spherical and symmetrical shapes with respect to the axis ZZ 'and to the plane XX', YY 'of said parts forming washers 13 ⁇ 13 2 and also with regard to the parts forming half-collars 12,, 12 2 with nestable surfaces 14 having a symmetrical profile with respect to the axis YY 'of said parts, such as a separation surface in the form of a sinusoid as shown in FIG. 2.
- the end 7 of the head 3 of the anchoring element preferably comprises an imprint 16 able to cooperate with any screwing tool such as for example of hollow hexagonal shape with even at the bottom of this imprint a channel, not shown on the figures which can open up to the other end of part 5 of the anchoring element capable of being fixed in the bone, when the latter is a screw as shown in the attached figures; such screws are called cannulated pedicles and allow the orientation of the screw to be controlled when it is screwed, by means of a pin around which said internal hollow part of the screw is slid.
- the screws may of course not be thus cannulated.
- said intermediate crown 9 can be of polygonal external shape such as for example hexagonal: this intermediate crown 9 being of a relatively large diameter such as for example 10 mm for a length L total of the anchoring element from 40 to 70 mm allows to have a large bearing surface with the screwing key, avoiding any risk of matting and allowing a good screwing torque which can even avoid tapping the bone beforehand.
- the height of the head 3 of this screw can be of the order of 15 mm between the intermediate ring 9 and its end 7, with a diameter of the part receiving the bore 11 of the clamping element of the order of 4.5 to 5 mm, the internal diameter of said bore 11 being from 6 to 6.5 mm.
- the locking means 6 is a nut, preferably self-locking, screwed onto the threaded end 7 of the anchoring head 3 and which may be of a diameter greater than the part of the head 3 around which can rotate the washer portions 13 of the parts of the clamping means 8; the use of a self-locking nut avoids an additional locking system of the lock nut type and therefore promotes compactness of the assembly.
- the body of the screw 5 comprises a so-called lower part 5 on the side of its end, the tops of the threads 17 follow a cylinder of the same external diameter d and the thread bottoms 18 follow a conical surface converging towards the end of screw 5; the height h of this lower part 5 2 can be approximately two thirds of the total thread length of the screw 5; by way of example, the external diameter D can be of the order of 6 mm for a total length of screw 5 from 25 to 50 mm with a thread pitch of 3 mm, and a diameter of the thread bottom passing from 4 to 4.5 mm, up to 3 to 3.5 mm, in seven to eight thread pitches; said thread having a triangular profile whose front face 20 is inclined in the direction of screwing and the rear face is almost perpendicular to the axis ZZ 'of the screw 5 in order to oppose a maximum force to the tearing
- Such thread profiles avoid the risk of loosening and facilitate the initiation of screwing, avoiding pre-tapping; increasing the
- an orientable fixing device can be fixed in a simple and rapid manner according to the following operations:
- the body of the screws 5 is screwed into each vertebra 2c after having previously drilled them, by means of a key which is fitted onto the intermediate crown 9 of polygonal shape and this without therefore having to pre-tap a hole in the bone: the screw can also be guided on a spindle entering the internal channel provided for this purpose,
- the rod 4 is positioned in the half-housings 10 provided for this in the half-collars 12 2 ,
- the second separable part 8 2 is put in place, forming the other half-stirrup, on the screw head 3 and coming to cover and enclose the rod 4, which second stirrup automatically aligns with the lower stirrup due to its symmetrical and complementary shape with it, - the nut 6 is screwed by means of a tubular key which allows the passage for example of a screwdriver coming to be housed in the cavity 16 located at the top of the screw head 3: it is thus possible to maintain the assembly of the screw 5 and to avoid its driving in rotation during the tightening of the nut 6, - the rod 4 is ideally oriented and positioned connecting several anchoring devices before the final tightening of the nuts 6, immobilizing the rod and therefore all of the vertebrae 2c in the desired position.
