Definitions
- the invention relates to a damping element according to the preamble of claim 1.
- a damping element of the generic type is already known from FR 2 812 186 PASQUET, which can be used within a spinal fixation device, for example as a connecting element between two adjacent pedicle screws.
- This known damping element essentially comprises two axially external longitudinal connecting elements and a part arranged between them, which is made of a material with higher elastic deformability than the external connecting elements.
- a disadvantage of this known damping element is that the spring rate is determined by the geometry and the choice of material of the middle, elastic part.
- the invention seeks to remedy this.
- the invention has for its object to provide a damping element with a progressive spring rate, the course of which is selectable.
- the invention solves the problem with a damping element having the features of claim 1.
- a progressive spring rate is adjustable, which ensures a sufficiently large elastic compliance with small spring travel. This allows sufficient freedom of movement of the spine in this area; - With an adjustable spring travel, a stronger resistance is used, so that an overload of the posterior elements can be prevented; and
- the dimension X is preferably between 0 mm and 2 mm.
- the spring travel of the spring element is adjustable at the spring rate.
- the front end of the clamping sleeve inserted into the cavity of the spring element comes into contact with the end wall of the cavity, so that when the spring element is axially compressed further, the end wall is deformed in the cavity of the spring element and thus there is a higher spring rate f 2 .
- the field element is preferably made of an elastomer, while the clamping sleeve is preferably made of a metallic material, in particular titanium.
- the front end of the clamping sleeve is convex.
- This spring rate f 2 can be influenced by the shape of the convex end face at the front end of the clamping sleeve, so that, for example, with a flat convex end face, greater progressiveness of the spring rate f 2 can be achieved than would be the case with a strongly curved convex end face.
- the connecting parts are rotatably and axially positively connected to the spring element.
- the connecting parts are preferably equipped with barbs on their end faces directed against the spring element, which barbs could be cast into the ends of the spring element.
- a connecting part on the outside comprises a rod coaxial with the longitudinal axis, as a result of which the damping element can be connected, for example, to a bone anchoring element.
- the second connecting part is designed as a bushing with a central bore which is coaxial with the longitudinal axis, the clamping sleeve being able to be passed through the central bore at least partially.
- a rod-shaped longitudinal member is preferably blocked in the clamping sleeve by wedging an inner cone arranged in the central bore of the bushing (21) with a complementary outer cone on the clamping sleeve.
- the adapter sleeve has a coaxial, open hole at the rear end.
- the radially elastic deformability of the clamping sleeve is achieved by at least one slot radially penetrating the wall of the clamping sleeve.
- the compression sleeve is preferably compressed by means of a thread arranged on the bush, by means of which a blocking means, preferably a nut, can be screwed.
- Fig. A line exploded view of an embodiment of the damping element according to the invention.
- Fig. 2 shows a longitudinal section through the embodiment of the damping element according to the invention shown in Fig. 1 in the assembled state.
- an embodiment which comprises a damping element 1 with a longitudinal axis 3, an axially external, longitudinal connecting part 4, an axially opposite, external, hollow-shaped connecting part 5 and an elastic middle part 2 arranged coaxially therebetween.
- the hollow body-shaped connecting part 5 is designed as a hollow cylindrical sleeve 21 and has an outer diameter which is that of the elastic Middle part 2 corresponds.
- the longitudinal connecting part 4 comprises, axially on the outside, a circular cylindrical rod 12 and a flange 11 adjoining the elastic middle part 2, the outer diameter of which corresponds approximately to that of the elastic middle part 2.
- the hollow body-shaped connecting part 5 has a first end face 7, which is directed towards the elastic central part 2 and is orthogonal to the longitudinal axis 3.
- the flange 11 on the longitudinal connecting part 4 directed towards the elastic middle part 2 has a second end face 6 orthogonal to the longitudinal axis 3.
- the end faces 6; 7 directed against the elastic middle part 2 on the connecting parts 4; 5 are provided with barbs 8 which are concentric with the longitudinal axis 3 and are arranged in a circular and peripheral manner.
- the barbs 8 are in the manufacture of the longitudinal beam 1 in the axially outer ends 9; 10 of the elastic middle part 2, so that an axially and rotationally positive connection between the elastic middle part 2 and the axially external connecting parts 4; 5 is produced.
- the elastic middle part 2 is of circular cylindrical design here and comprises a spring element 20 coaxial with the longitudinal axis 3 with a likewise coaxial cavity 13 and a clamping sleeve 15 arranged coaxially in the cavity 13.
- the cavity 13 is open axially against the hollow-shaped connecting part 5 and against the longitudinal connecting part 4 is completed with an end wall 14 orthogonal to the longitudinal axis 3.
- the clamping sleeve 15 can be inserted axially into the central bore 16 in the hollow body-shaped connecting part 5 and into the cavity 13.
- the clamping sleeve 15 has at its front end 17 directed against the end wall 14 of the cavity 13 a convex end surface 18 which, in the undeformed state of the elastic middle part 2, axially by a dimension X from the end wall 14 of the cavity 13 is spaced (Fig. 2). In this way it can be achieved that, in the event of an axial pressure load on the elastic middle part 2, this is first deformed with the spring rate ⁇ of the spring element 20.
- the apex of the convex end face 18 comes to rest against the end wall 14 of the cavity 13 at the front end 17 of the clamping sleeve 15, so that in the case of a further axial compression of the elastic middle part 2, the end wall 14 is deformed in the cavity 13 of the spring element 20 and thus there is a higher spring rate f 2 .
- This spring rate f 2 can be influenced by the shape of the convex end face 18 at the front end 17 of the tensioning sleeve 15, so that, for example, a flat-shaped convex end face 18 makes the spring rate f 2 more progressive than a strongly curved convex end face 18 would be the case.
- the dimension X and thus the transition from the spring rate fi of the spring element 20 to the higher spring rate f 2 of the spring element 20 resting on the front end 17 of the clamping sleeve 15 can be adjusted by the axially variable position of the clamping sleeve 15 relative to the spring element 20.
- the hollow cylindrical connecting part 5 is formed here in two parts and comprises a bushing 21, which has a thread 22 at its outer end 23.
- the bushing 21 is drilled through with a central bore 16 coaxial with the longitudinal axis 3, the central bore 16 widening toward the outer end 23 of the bushing 21 with an inner cone 25.
- the diameter of the central bore 16 is dimensioned such that the clamping sleeve 15 can be inserted into the central bore 16.
- the clamping sleeve 15 is provided at its rear end 24 with an outer cone 26 which can be wedged in the inner cone 25 in the central bore 16 of the sleeve 21.
- the clamping sleeve 15 has a coaxial blind hole 19 which is open at the rear end 24 and into which a rod-shaped longitudinal member (not shown) can be inserted from the rear end 24. Furthermore, the rear end 24 of the clamping sleeve 15 is provided with at least one slot 27 radially penetrating the wall of the inner spring element 15, so that when the outer cone 26 is pressed into the inner cone 25, the rear end 24 of the clamping sleeve 15 is radially compressed and into the blind hole 19 introduced rod-shaped longitudinal member can be fixed in the clamping sleeve 15.
- the axial displacement of the clamping sleeve 15 relative to the spring element 20 takes place by means of blocking means 20, which are designed here as a nut 28 which can be screwed onto the bushing 21 via the thread 22.
- the nut 28 has a coaxial bore 29 with an internal thread 30 and an axially external constriction 31.
