Definitions

  • the invention relates to a damping element according to the preamble of claim 1.
  • a generic damping element for the dynamic stabilization of two adjacent vertebral bodies is known from EP-A 0 516 567 NAVAS.
  • This known damping element comprises a coaxial damping body, each with an axially external spherically convex connecting part, by means of which the damping element can be fastened to two pedicle screws.
  • the ball joint-like connection between the two connecting parts and the heads of the pedicle screws allows the damping element to be connected to the pedicle screws at a variable angle between the longitudinal axes of the pedicle screws and the central axis of the damping element.
  • a disadvantage of this known damping element is that the distance between the pedicle screws is predetermined by the geometry of the damping element.
  • the invention seeks to remedy this.
  • the invention has for its object to provide a damping element which is at least at one of its ends polyaxially pivotable and axially telescopic connectable to a side member.
  • the invention solves the problem with a damping element having the features of claim 1.
  • the damping element When the ball joint is unlocked, the damping element can be pivoted polyaxially with a rod-shaped longitudinal member of a device for stabilizing vertebral bodies. Therefore, no longitudinal beams have to be bent when a longitudinal beam is implanted within a spinal stabilization device; and - The damping element is axially telescopically connectable to a rod-shaped longitudinal member of a device for stabilizing vertebral bodies.
  • the ball joint comprises a spherically convex, radially elastically compressible clamping body with a diametrical central bore having a bore axis, so that a rod-shaped longitudinal member inserted into the central bore is blocked relative to the clamping body in the central bore when the clamping body is compressed.
  • the ball joint preferably allows the clamping body to rotate about an angle ⁇ measured between the bore axis of the central bore in the clamping body and the central axis of the spring element within a range from 0 ° to ⁇ 25 °. This provides the advantage that a rod-shaped longitudinal member inserted into the central bore of the clamping body can be pivoted relative to the spring element and therefore the rod-shaped longitudinal member does not have to be bent.
  • the ball joint preferably comprises two axially separated bearing shells which at least partially accommodate the clamping body, so that the clamping body is compressed uniformly when the bearing shells are pressed together and the ball joint can thus be rigidly blocked.
  • the bearing shells can be pressed axially against the clamping body by means of the clamping means, the spring element preferably having a coaxial, threaded pin at its first end and that the first bearing shell is integrated axially at the end in the pin, such that the bearing shell tapers against the second end of the spring element.
  • the clamping means are preferably designed as a nut which can be screwed onto the thread of the pin.
  • the second bearing shell is preferably integrated concentrically in the bore of the nut.
  • the nut comprises a coaxial bore with at least two axially adjacent longitudinal sections, the outer longitudinal section directed against the spring element having an internal thread complementary to the thread of the pin and the second bearing shell being integrated in the adjacent longitudinal section in such a way that it is self-supporting extended against the external longitudinal section.
  • the clamping means are coaxially drilled through for the passage of a rod-shaped longitudinal beam.
  • the clamping body has a slot parallel to the bore axis of the central bore, which slot penetrates the wall of the clamping body from its outer wall to the central bore.
  • the damping element comprises a connecting part which is coaxial with a rod at one of its ends and which can be connected to a further part within an osteosynthetic stabilizing device.
  • the damping element additionally comprises a rod-shaped longitudinal beam which can be inserted into the central bore of the clamping body and can be detachably fixed in the clamping body.
  • Fig. 2 is an enlargement of the segment marked by the circle A in Fig. 1.
  • an embodiment is shown which comprises a hollow cylindrical damping element 1 with a central axis 11 and a releasably lockable ball joint 20 for the polyaxially pivotable connection of the damping element 1 with a rod-shaped longitudinal member 3 having a longitudinal axis 4.
  • the damping element 1 comprises, in addition to the ball joint 20, a spring element 10, which in the embodiment shown here consists of a metallic helical spring and a plastic part 31 penetrating into the gap 30 between the spring windings and diametrically narrowing the cavity 15.
  • the ball joint 20 is arranged at the first end 12 of the spring element 10, while at the second, axially opposite end 13 of the spring element 10 a coaxial rod-shaped connecting part 16 is arranged, which is suitable for connection to a further part (not shown) of a spine stabilization device.
  • the ball joint 20 here consists of a spherically convex clamping body 21 with a central bore 22 having a bore axis 27 and of two concave bearing shells 23, 24 complementary to the clamping body 21.
  • the first bearing shell 23 is integrated concentrically with the central axis 11 in the threaded pin 39 at the first end 12 of the spring element 10, in such a way that it tapers against the cavity 15 in the damping element 1.
  • the threaded pin 39 is penetrated by a bore 14 coaxial with the central axis 11 and opening into the cavity 15, so that the bore 14 is suitable for receiving a rod-shaped longitudinal member 3 which is passed through the central bore 22 in the clamping body 21.
  • the second bearing shell 24 is integrated in a nut 25 which can be screwed onto the threaded pin 39 via the thread 26.
  • the cavity 15 is closed.
  • a rod-shaped connecting part 16 coaxial with the central axis 11 is arranged at the second end 13 of the spring element 10.
  • the clamping body 21 is provided with slots 28 which are parallel to the bore axis 27 and which penetrates the clamping body 21 from the outer wall 29 of the clamping body 21 to the central bore 22.
  • the clamping body 21 arranged between the bearing shells 23; 24 is thus clamped between the bearing shells 23; 24 and at the same time radially Bore axis 27 of the central bore 22 is compressed so that the longitudinal beam 3 inserted into the central bore 22 is blocked.
  • the nut 25 is penetrated by a bore 32 which is coaxial with the central axis 11 and which has a plurality of axially adjacent longitudinal sections 34; 35; 36 with different geometries.
  • the longitudinal section 34 adjacent to the first end 12 of the damping element 1 is provided with an internal thread 33 which is complementary to the thread 26 at the first end 12 of the spring element 10, while the central longitudinal section 35 comprises the second, likewise drilled through bearing shell 24 and the outer longitudinal section 36 is conical ,
  • the second bearing shell 24 is arranged such that it tapers towards the outer longitudinal section 36.
  • the cone 38 in the outer longitudinal section 36 widens against the outer end face 37 of the nut 25, so that a rod-shaped longitudinal member 3 can be pivotably received in the ball joint 20.
