Beschreibung
DETAILED DESCRIPTION OF THE INVENTION [0046] As can be seen in particular from FIGS. 1 to 3, in accord with one embodiment of the invention, the dynamic anchoring element 1 is formed as a polyaxial screw. It comprises a screw element 2 with a threaded shank part 3 and a head 4 formed in one piece therewith and a receiving part 5. The head 4 is substantially formed in the shape of a segment of a sphere and has on its end opposite to the shank part 3 a widened edge or collar 6, so that a flat front face 7 is formed which has a diameter which is larger than the diameter of the spherical segment-shaped section of the head. A recess for bringing into engagement with a screwing-in tool is further formed in the front face 7. [0047] The receiving part 5 is substantially formed cylindrically symmetric and has on one of its ends a coaxial first bore 10 the diameter of which is larger than that of the threaded section of the shank 3 and smaller than the spherical diameter of the spherical segment-shaped section of the head 4. It further has a coaxial second bore 11 which is open at the end opposite the first bore 10 and the diameter of which is large enough for the screw element 2 to be inserted through the open end with its threaded section through the first bore 10 and with the spherical segment-shaped section of the head 4 to the bottom of the second bore. In the receiving part, adjacent to the first bore 10 a section 12 is provided, shaped like a segment of a hollow sphere, the radius of which is substantially identical to the radius of the section of the spherical segment-shaped head 4. The receiving part further has a U-shaped recess 13, extending from the open end towards the first bore 10, the bottom of which is directed towards the first bore 10 and by which two open legs 14 are formed, only one of which is illustrated in the figures. An inner thread 15 is formed in the receiving part adjacent to the open end of the legs 14. The width of the U-shaped recess 13 is minimally larger than the diameter of a rod 100 to be received therein which connects several such polyaxial screws. The depth of the U-shaped recess is dimensioned in such a way that when the rod is inserted a fixing screw 16 can be screwed in between the legs. [0048] The section 12 of the receiving part which is shaped like a segment of a hollow sphere is preferably polished smooth or coated with a material which increases the sliding capacity, so the head 4 can easily be swiveled in the section 12 of the receiving part. Alternatively, or additionally the head 4 is polished smooth or coated. [0049] Between the inserted rod 100 and the head 4 of the screw element a pressure element 20 is provided. The pressure element 20 is formed in the shape of a cylinder and has a diameter which is smaller than the inner diameter of the second bore 11 of the receiving part and which is preferably identical to the diameter of the front face 7 of the head. The axial length of the pressure element 20 is slightly larger than or identical to the distance between the front face 7 of the head 4 and the bottom of the U-shaped recess 13 in the inserted state. The pressure element is resilient, in the illustrated embodiment it is formed from an elastomer, e.g., from polyurethanes or polysiloxanes. However, any suitable biocompatible material can be used. [0050] Between the pressure element 20 and the inserted rod 100 a cap 21 is provided, which covers the pressure element on the side facing the rod and which is constructed from an inflexible material, for example a synthetic material or a body-compatible metal. The outer diameter of the cap 21 is dimensioned in such a way that the cap is displaceable by sliding in the second bore of the receiving part and the inner diameter of the cap substantially corresponds to the outer diameter of the pressure element 20 when this is in an unloaded state. The cap overlaps the pressure element to such an extent that the pressure element is able to expand in the radial direction when put under load. [0051] [0051]FIG. 1 shows the unloaded state in which the screw element 2, the pressure element 20 and the cap 21 are inserted into the receiving part and the rod 100 is placed into the U-shaped recess 13, but the inner screw has not yet been screwed down. In this state the side 22 of the cap 21 facing away from the pressure element 13 is at a slightly higher position than the bottom of the U-shaped recess 13, so that the rod rests with its lower side on the surface 22 of the cap and thus a gap 23 is formed between the lower side of the rod and the bottom of the U-shaped recess 13. [0052] In operation, as shown in FIG. 1, first the screw element 2 is inserted into the receiving part 5 from the open end thereof until the head rests against the section 12 of the receiving part shaped like a segment of a hollow sphere. The screw element is then screwed into the vertebra. Then, the pressure element 20 together with the cap 21 placed thereon is inserted into the receiving part, the receiving part is aligned and the rod inserted. Finally, the inner screw 16 is screwed into the receiving part. [0053] As illustrated in FIG. 2, the inner screw is screwed in until it presses the rod against the bottom of the U-shaped recess and thus fixes the rod. At the same time, the rod presses on the cap 21, which serves for even distribution of the force of pressure exerted by the rod on to the entire surface of the pressure element. Due to the elasticity of the pressure element it is pre-compressed via the force exerted by the rod. At the same time, the pressure element takes on a shape curved outwards in the radial direction, shown in FIG. 2. In the state shown in FIG. 2 the pressure element 20 is under bias in respect of the screw head 4 and due to the return force it presses with its lower side evenly on the front face 7 of the head. In this way, the head is pressed against the section 12 of the receiving part. [0054] The screw element 2 screwed into the vertebral body is moved out of its resting position by a self-movement of the vertebral column. When the vertebra moves towards the rod at an angle of 90° to the rod axis there is uniform compression of the pressure element and the angle of the shank relative to the receiving part does not change. When the vertebra moves at an angle other than 90° to the rod axis, as shown in FIG. 3, there is a swiveling of the head, which easily slides in the section 12 of the receiving part. Thereby, the front face 7 of the screw head exerts a compression force on to the pressure element on one side which compresses it on one side near the edge. On the other hand, on the opposite side, the pressure element standing under pre-stress expands owing to the relief of pressure. Thus, the pressure element always remains in contact with the screw head. [0055] Due to the elasticity of the pressure element, the compression effects a return force onto the screw head. In this way, a movement of the vertebra back into its original position in which it has been placed by the surgeon is supported. [0056] By the choice of an elastomer material for the pressure element with a desired compressibility a limitation of motion of the vertebra can be adjusted. If the material is only slightly compressible, the device allows only a small deflection out of the resting position. If the material properties are changed, larger swivel ranges are possible. Those skilled in the art can readily substitute materials using routine experimentation. Body-compatible elastomer can be used as elastomer material, e.g., polyurethanes or polysiloxanes. [0057] The swivel range can also or additionally be set by the selection of the diameter of the collar 6 of the screw head relative to the diameter of the second bore 11 of the receiving part. When the collar 6 abuts on the wall of the receiving part in the swiveled position of the screw element 2, no further swiveling is possible. [0058] [0058]FIG. 4 shows a pressure element 25 according to a second embodiment. The pressure element 25 has a housing formed in a box shape, consisting of a lower part 26 and an upper part 27, which closes the lower part like a lid. Inside, at least two preferably four or more helical springs 28 are arranged opposite one another which are distanced evenly apart in the circumferential direction, and which are connected with one of their ends to the lower part and with their other end to the upper part. The helical springs 28 are arranged near the housing wall, as the compression forces are greater at the edge of the pressure element than in the center, as can be seen in FIG. 3. The strength of the helical springs is selected in such a way that a desired or required compression via the screw head can be achieved. [0059] If the anchoring device comprises the pressure element according to the second embodiment, the cap 21 described in the first embodiment is not necessary, as the upper side of the pressure element consists of an inflexible material. [0060] The operation of the anchoring device is like that of the first embodiment. In order to prevent lateral displacement of the pressure element 25 in the receiving part, the diameter of the pressure element is in a further modification only slightly smaller than the diameter of the second bore 11 of the receiving part. [0061] In a further embodiment, the pressure element itself is formed as a helical spring. The diameter of the helical spring then corresponds to the diameter of the box-shaped housing according to the second embodiment. Other types of springs are also possible, e.g., one or more spring washers. [0062] In an alternative embodiment in the elastomeric pressure element, helical springs are contained in an arrangement identical to or similar to that according to FIG. 4 and are cast into an elastomeric material during manufacture of the pressure element. These springs then serve to support the elastic properties of the elastomer. [0063] In a modification of the first embodiment, the pressure element 20 and the cap 21 are pre-mounted in the receiving part 5 and secured against falling out, e.g., by crimped bores provided in the receiving part and countersunk bores in the pressure element corresponding therewith. In this case the pressure element 20 and the cap 21 have a coaxial central bore which enables a screw tool to be guided through to screw the screw element 2 into the bone. The bore can also be provided if the pressure element and the cap are not pre-mounted. [0064] In a further embodiment, the pressure element is formed in such a way that the face facing the cap 21 and/or the front face 7 of the head is curved concavely towards the inside of the pressure element. This, in cooperation with the flat face of the cap and/or the screw head, creates an increase in the pressure elasticity at the edge. [0065] In a further modification, the head does not have the collar, but is formed, e.g., in the shape of a semi-sphere, as illustrated in FIG. 6, so that the front face has the largest diameter of the screw head. It is decisive that there is a sufficiently large front face for cooperation with the pressure element which guarantees force transmission at the edge. [0066] In a second embodiment of the anchoring device shown in FIG. 5a, the resting position of the screw element 2 relative to the receiving part 5 is at an angle α to the central axis M of the receiving part which is different from 0°. In this case, the screw element 2′ is constructed in two parts. It comprises a head 40 and a threaded shank 30 which can be connected thereto. The threaded shank 30 has on one of its ends a thread-free section 31. On this end there is further provided on the front a recess 32 for bringing into engagement with a screw tool. The head 40, like that of the screw element of the first embodiment, comprises a spherical segment-shaped section and a collar 41 adjoining the spherical segment-shaped section on the side facing away from the shank and having a front face 42 for cooperating with the pressure element. On the side facing away from the front face the head 40 has a bore 43 extending at a predetermined angle α to the axis of symmetry of the head. The diameter of the bore is identical to the outer diameter of the thread-free section 31 of the shank 30, so that the shank can be inserted into the bore by friction locking. To improve the clamping effect on to the inserted shank the head can have slits, not illustrated, in its wall, so that the bore has a resilient edge. [0067] Alternatively, an inner thread is provided in the bore 43 and an outer thread on the shank section 31 matching the inner thread to allow screwing in of the shank into the head. [0068] The remaining parts of the anchoring device are as in the embodiment according to FIGS. 1 to 3 or its modifications. [0069] In operation first the shank 30 is screwed into the vertebra. Then, the receiving part 5 with its first bore 10 is placed diagonally onto the shank 30 or onto the projecting thread-free section 31 and then the head 40 with the pressure element and, if applicable, the cap are inserted into the receiving part in the pre-compressed state with a suitable tool and with the bore 43 slid onto the shank. The longitudinal axis of the shank 30, thus, has a predetermined angle α to the central axis of the head 40 and therefore to the central axis of the receiving part 5. Subsequently, the rod is inserted and finally the whole arrangement is fixed via the inner screw 16, as in the first embodiment. Like in the first embodiment, when the vertebra moves, the return force causes the head to be forced back into its resting position. Although the angle is preset by the angle of the bore 43, the surgeon can still perform an adjustment by rotating the receiving part about its axis or by a minimal swiveling of the head. [0070] In a further modification of the second embodiment, the head is constructed in one piece with the shank, but the front face of the head which forms the support face for the elastic pressure element is at an angle to the axis of the shank. In FIGS. 5b to 5 e, the manufacturing steps of a screw element 200 of this kind are shown. The screw element 200 has a threaded shank 300 and a spherical segment-shaped head 400 connected thereto in one piece. As shown in FIG. 5b, the head is milled off in such a way that the front face 700 has a predetermined angle to the axis of the shank. Subsequently, as shown in FIG. 5c, a bore 701 with an inner thread is produced, which extends perpendicular to the front face 700. Into this bore, as shown in FIG. 5c, a screw 600 with a collar-shaped head and with a recess 601 for subsequent screwing into the bone is screwed into the head, the diameter of the collar being larger than the diameter of the head 400. The finished screw element 200, shown in FIG. 5e, is then inserted into the receiving part. [0071] In operation, the screw element 200 is inserted into the receiving part and then screwed into the bone. By means of the face 700 extending at the predetermined angle to the axis of the shank the screw element 200 has the predetermined angle relative to the receiving part in the resting position. The insertion of the pressure element and the rod takes place as previously described. [0072] The collar can also be constructed in one piece with the screw element. [0073] In a further modification of the second embodiment, shown in FIGS. 10a-10 c, it is not the receiving part 5 itself which comprises the section shaped like a segment of a sphere against which the head rests, but in the receiving part an insert 500 made of an elastomer is provided, which is constructed with a cylindrical outer wall and surrounds the spherical segment-shaped section of the head laterally starting from the first bore 10, or which, as shown in FIG. 10a, is ring-shaped and has only a support face 501 for the screw head. Further, a rigid pressure element 502 which presses on the head 4 is provided. The pressure element 501 has a spherical segment-shaped recess which fits into the screw head. In operation, after adjustment of the screw 2 and the receiving part 5 in respect of one another, the screw head 4 is pressed via the fixing screw 16 and the pressure element 502 at a desired angle against the insert, which therein, because it is slightly compressed, is under bias, as shown in FIG. 10b. This position forms the resting position. When there is a movement of the vertebra, the screw head presses against the insert 500, so that it deforms at this point and enables the screw to move out from the resting position, as shown in FIG. 10c. Simultaneously, the increasing return force forces the head back into its resting position. In this embodiment, the desired angle of the screw shank to the receiving part, which is supposed to form the resting position, can be freely adjusted. [0074] In a further modification, the pressure element is formed so as to be wedge-shaped. [0075] In a third embodiment, shown in FIG. 6, the anchoring device is formed in such a way that the head and the rod can be independently loaded. For this purpose, in contrast to the first embodiment, the pressure element 50 has a first elastic section 51 and a second inflexible section 52 adjacent thereto, which are rigidly connected to one another. The inflexible section 52 has a U-shaped recess 53, the dimensions of which are such that the rod 100 can be inserted therein. The depth of the U-shaped recess of the pressure element, seen in the direction of the cylinder axis, is greater than the diameter of the rod. The open legs 54, 55 formed by the U-shaped recess thereby project beyond the rod when it has been inserted. Further, a nut or bushing type closing element 56 is provided, which has an outer thread 57 cooperating with the inner thread of the receiving part and an inner thread 58. An inner screw 59 is provided to be screwed into the closing element 56. [0076] In operation, when a force is exerted on the legs of the rigid pressure element part 52 and the elastic pressure element part 51 via the closing element 56, a force is applied to the screw head. The rod is fixed independently via the inner screw 59. If desired, the rod can also be movably held. In this case, the inner screw is screwed in only to such an extent that the rod can still slide in the U-shaped recess of the receiving part. [0077] In the embodiment shown, in which sections 51 and 52 are rigidly connected to one another, the pressure element 50 is constructed in one piece. In a modification, it is constructed in two pieces and then consists of an elastic part 51 according to the embodiment according to FIG. 1 and a non-elastic part 52, which has the U-shaped recess. [0078] [0078]FIG. 7 shows a dynamic stabilization device for vertebrae according to a first embodiment. This is, in particular, applicable in a case in which an intervertebral disc or a vertebra is removed and replaced by a rigid fusion element 60, e.g., a tube-shaped implant with openings in the wall and, e.g., filled with bone mass to allow bones to grow in. [0079] The stabilization device comprises two dynamic bone anchoring devices 1, 1′ in the posterior area, which are connected to one another via a rigid rod 100. Each of the bone anchoring devices 1, 1′ is formed according to one of the previously described embodiments. Because of the elastic construction of the pressure element and the associated damping effect there is intermittent, limited load onto the fusion element 60, resulting in acceleration of the growing in of bone in and around the fusion element. This accelerates the healing process. [0080] [0080]FIG. 8 shows a dynamic stabilization device for vertebrae according to a second embodiment. This can be applied in particular in a case in which an intervertebral disc has been removed and replaced by an intervertebral disc prosthesis 61. The stabilization device comprises two dynamic anchoring devices 101, 101′ which are connected to one another via a rigid rod 100. At least one of the anchoring devices 101, 101′ is formed according to the embodiment shown in FIG. 6, which is characterized in that pressure is exerted on the screw head via the pressure element 50, but the rod still remains displaceable in the axial direction. The stabilization device further comprises a spring element 102 provided on the rod between the two anchoring devices, and also at least one stop 103 on the rod arranged on the side opposite to that spring element 102 of the anchoring device in which the rod 100 is held slidingly. In the example shown in FIG. 8, two such stops are provided and the rod is slidingly held in both anchoring devices 101, 101′. The spring element 102 is inserted in between the anchoring devices under bias and thus acts as extension spring. [0081] In operation, the combination of posterior longitudinal resiliency of the rod 100 and the polyaxial damping of the anchoring devices 101, 101′ enables control of movement and relieving of the stress on the intervertebral disc prosthesis. The stabilization device can be applied for any artificial intervertebral disc structure. [0082] [0082]FIG. 9 shows a further application of the stabilization device illustrated in FIG. 8, which comprises the extension spring rod and the dynamic anchoring devices in the form of the previously described polyaxial damping screws in the posterior area. In this case of application, the human intervertebral disc is damaged to an extent that, when relieved from stress, it will recover. The stabilization device therein relieves the stress on the human intervertebral disc and, at the same time, limits the extent of movement, so that extreme movements, which would further damage the intervertebral disc, cannot occur and the intervertebral disc is able to recover in the resting phase, e.g., at night or while lying down. [0083] In FIGS. 11 to 13, a further embodiment of the invention is described. Elements which are corresponding to the elements of the embodiment shown in FIGS. 1 to 3 have the same reference numerals. According to FIG. 11, this embodiment comprises in addition to the elastic pressure member 20, which is arranged between the rod and the head, a second elastic pressure member 600. The second pressure member 600 is ring-shaped and arranged such that it encompasses the screw head at the location where the collar 6 is formed adjacent to the spherical segment-shaped section. In the embodiment shown, the second pressure member 600 is formed as O-ring. The outer diameter of the pressure member and its inner ring diameter are dimensioned such that in the unloaded state shown in FIG. 11 in which the pressure member is inserted into the receiver member 5, the ring is in contact with the outer side of the head and the inner wall of the receiver member. Suitably, at the time of inserting of the screw element into the receiver member the second pressure member 600 is already placed on the screw head. [0084] In operation, in the loaded state shown in FIG. 12 in which the rod is fixed, the pressure member 600 is deformed. Due to the compression occurring when the pressure element is deformed, the pressure element is spring-biased towards the screw head. According to FIG. 13, the first pressure member 20 causes a return force acting upon the front face 7 of the screw head from the top, which is represented by the arrow F1, when the screw element 2 moves out of its resting position, whereas the second pressure member 600 generates a return force, illustrated by arrow F2, on the screw head acting from laterally below the front face 7 and being diagonally offset with respect to the force F1. Therefore, return forces acting upon the screw head which return the latter into its original position as shown by the arrow A in FIG. 13 are increased by means of the second pressure member 600. In addition, the second pressure member 600 reduces wear of the first pressure member 20. [0085] By selection of the materials of the first pressure member 20 and the second pressure member 600, which can be different, a desired adjustment of the damping can be achieved. For instance, the first pressure member is formed of a harder or less compressible material than the second pressure member. [0086] In a modification of this embodiment, the second pressure element is not formed as O-ring but as a molded ring. [0087] The invention is not limited to the above-described embodiments. Combinations of elements of the individual embodiments with elements of other embodiments are possible. In particular, the invention is also not confined to a polyaxial screw. For example, a hook can also be provided as anchoring element instead of the threaded shank. The receiving part can also be constructed in such a way that the screw can be inserted from below into the receiving part. In this case, a molded ring is provided as end stop for the screw head. [0088] The section 12 of the receiving part which supports the head is not restricted to have a spherical shape, it can also be conical or can have another shape suitable for the particular application. [0089] In a stabilization device using the anchoring device according to the embodiments described above, a force acting on the rod due to a movement of the bone segment or the vertebra in which the anchoring device is anchored is prevented from being fully transmitted to the area where the shank is anchored. Thus, loosening of the shank in the bone can be reduced or prevented. [0090] Those persons skilled in the art easily recognize that the invention is not limited to a dynamic anchoring device wherein the screw element is inserted from above in the receiving part, but is also applicable to a dynamic anchoring device wherein the screw element can be inserted from below through the bore.
