Definitions
- the present invention relates to an artificial joint, in particular for replacing the human hip joint, consisting of a joint head with a convex, circular cutting contour with the center M x and the radius R and an articular socket with a concave, circular cutting contour and the center M 2 and the Radius R 2 and a pressure distribution body slidably arranged between these two on their functional surfaces, the adjoining sliding surfaces of which have a curvature adapted to the functional surfaces, and the pressure distribution body has a thickness d on the connecting line of the centers of rotation M, and M 2 of the two circular cutting contours of the joint head and has the socket.
- the radii R 2 and R x are dimensioned such that R 2 > R L + d.
- the object of the present invention is to improve the artificial joint described at the outset in such a way that the pressure distribution body cannot be dislodged from the joint socket. At the same time, however, easy assembly of the artificial joint, in particular when it is inserted into the human body, is to be ensured.
- the joint socket has a circumferential edge such that the artificial joint has a swivel range of the joint head in its frontal plane perpendicular to the main functional direction, which is less than 180 °, preferably approximately 120 °.
- this limitation of the swivel range is brought about by the fact that, in deviation from the equatorial circumferential line of the joint socket, the pan edge has at least one preferably wave-shaped elevation in the frontal plane, in particular two diametrically opposite elevations above the circumferential line.
- the freedom of movement of the disc in the main functional direction is thus greater than in the plane perpendicular to it, ie in the frontal plane.
- a slot is formed in the two wave-shaped, diametrically opposite elevations of the joint socket according to the invention, which enables the pressure distribution body to be inserted into the joint socket during the operations. This insertion through the slot takes place with one movement and in one position of the disc, which the disc can no longer carry out or assume after the articulated head has been attached.
- the joint socket has a peripheral edge such that the joint has a swivel range greater than or equal to 180 ° in its main functional direction.
- the expansion of the swivel range is advantageously achieved in that the joint socket, in deviation from its equatorial circumferential line based on a semicircular cutting contour, has such a socket edge profile that at least one, in particular, wave-shaped indentation is provided in the area between the two elevations in the main functional direction plane .
- two diametrically opposed indentations are formed.
- indentations also allow the pressure distribution body to be inserted into the joint socket if the disc, which is advantageous, coincides with its outer radius with the inner radius of the joint socket and is thus drawn up to approximately the equatorial circumferential line of the joint socket.
- FIG. 1 is a perspective view of an artificial joint according to the invention in the unmounted state
- FIG. 3 shows a perspective view of a pressure distribution body
- FIG. 4 shows a section through an acetabular cup according to FIG. 2 with an inserted pressure distribution body
- Fig. 5 shows a section through an inventive joint in its functional position.
- the joint head 1 has a convex, circular cutting contour, so that a joint head ball is formed which is flattened in the region of its shaft attachment la.
- the socket 2 also has a " circular sectional contour, so that a shell-shaped shell body with a semicircular cross section is formed. This shell body has an equatorial circumferential line X.
- the pressure distribution body 3 is designed such that its sliding surfaces 6, 7 rest against the functional surfaces 4, 5, ie the functional surface 4 of the socket 2 and the functional surface 5 of the joint head 1, so that its sliding surfaces 6, 7 rest against the functional
- RSATZBUTT RULE26 surfaces 5 have appropriately adapted curvature.
- the joint head 1 has, see FIG. 5, the rotation center M 2 and the radius R ⁇ and the joint socket 2 has the rotation center M 2 and the radius R 2 .
- the pressure distribution body 3 has a thickness d on the connecting line of M 1 and M 2 .
- the joint parts designed in this way form a dimeric joint chain with two joint axes through M : and M 2 in the inserted state, the radius R of the joint axis path resulting from the relationship
- R R 2 - R 1 - d, where R 2 > R : + d,
- This design of the artificial joint requires a pressure-stable joint behavior in every bending or swiveling position of the joint head 1.
- the socket 2 has a peripheral edge 8 such that the joint according to the invention has a swivel range in its frontal plane Z-Z perpendicular to the main functional direction Y-Y, which is less than 180 °, preferably approximately 120 °.
- the pan edge 8 deviating from the equatorial circumferential line X in the frontal plane Z-Z, has at least one in particular wave-shaped elevation 9, preferably two diametrically opposite, wave-shaped elevations 9.
- the joint according to the invention has a swivel range greater than 180 ′′ in its main functional direction Y-Y
- the pressure distribution body 3 advantageously has an outer radius which, apart from an existing lubrication clearance, corresponds to the radius R 2 , ie the inner radius of the socket 2. 4 shows how the pressure distribution body 3 can be inserted into the joint socket 2 through the slot formed between the wave-shaped elevations 9 in the area of the wave-shaped indentations 10.
- the disc or pressure distribution body 3 cannot luxie in the event of a possible dislocation of the joint head 1 from the socket 2 ren.
- the joint parts according to the invention are dimensioned such that the diameter of the joint head 1 is smaller than the distance between the opposing wave-shaped elevations 9, so that the joint head 1 can be used in any case from the open side of the socket 2.
- the joint head 1 is covered up to the equator XX by the disc, ie by the pressure distribution body 3, in which the pressure distribution body 3 is raised circumferentially by a section 11 up to the equator.
- the pressure distribution body 3 can be expanded cylindrically in the region of section 11 towards the joint head 1. This additionally complicates luxation of the joint head 1 with respect to the pressure distribution body 3.
- the present invention is not limited to the embodiment shown. It may be possible within the scope of the invention if the limitation of the pivoting range of the joint head 1 in the frontal plane is realized by a coupling part which can be screwed onto the socket 2.
