Definitions
- the invention relates to a screw-in with a self-tapping thread, wherein a circumferential thread rib is divided by at least one flute in thread teeth, and with at least one
- Threads are widely used as structural elements of general engineering. Usually threads are cylindrical. In addition, conical thread z. B. for oil field pipes in use. A large number of different thread profiles are known and defined in standards. Usually, the thread profile on a workpiece is immutable, that is, that the thread profile at the beginning of the thread is identical to that at the threaded end. However, exceptions are conceivable in which a flowing at least in a portion of the thread changing shape shape of the thread profile formed from thread groove and thread tooth could be advantageous, for. B. to facilitate the insertion of a screw thread in a nut thread.
- Bone contact can be screwed.
- the second case only a very poor primary fixation will be achieved.
- there is a risk of Ausiockerns of the implant which would mean as a consequence, a repeated operation of the patient.
- the object is achieved in that the flute cuts the thread teeth at an angle which is opposite to the direction of the pitch angle of the thread.
- the cutting edge formed between the flute and thread tooth is displaced to the feed direction opposite side of the thread tooth, or runs the helical or helical direction of the flute opposite to the twist direction of the thread and the helix angle of the flute is greater than that
- the flute extends obliquely in the screw-in.
- the flute has a twist.
- the cutting edge is arranged on the rear, directed to the equator edge of the screw-in. Furthermore, it is favorable that the helix angle or the helix angle is greater than that
- the screw-in body is realized as an implant and in another preferred embodiment as an artificial acetabular cup.
- Screw caps are designed in such a way, also z. B. self-tapping screws.
- screw-in bodies eg artificial hip joint pans
- these flutes often run neutral, that is to say with one Twist angle of zero degrees.
- the cross section of the respective thread tooth then forms a cutting surface, which is slightly positive due to the pitch angle of the thread.
- Some self-tapping self-tapping screws have slight left twisted or slightly obliquely to the left flutes, however, compensate only the pitch angle of the thread and are then positioned neutral with their cutting surface. Links twisted flutes are known, for example, in taps, which are to carry away the chips resulting from cutting down the through holes.
- Fig. 1 shows a threaded artificial acetabulum according to the prior art.
- Fig. 2 an acetabular cup according to the invention is shown with a tilted to Pfannenpol thread tooth profile and negative helix angle of the flute.
- Fig. 1 shows the schematic representation of an artificial hip joint socket 1 according to the prior art in a slightly enlarged scale.
- the example shown has a spherical contour of the curved shell shell.
- the other flutes have been omitted for reasons of simplification.
- the central axis of the acetabulum is indicated by a dot-dash line 2 and the center of the flute by a dash-dotted line 7.
- Between both the negative helix angle ⁇ is formed.
- the helix angle corresponds to its angular size according to the pitch angle of the thread, so that the cutting edges formed on the thread teeth through the flute with respect to the feed direction when screwing transversely to the extension of the thread ribs, and thus neutral.
- FIG. 2 shows an artificial hip joint socket 9 of the same size and shape according to the invention.
- a single flute 16 has been drawn for reasons of simplification. Also on the representation of a twist was omitted because of the drawing effort.
- the four threads 11, 12, 13 and 14 existing thread has an asymmetrical tooth profile, which is inclined to the Pfannenpol. This tilting direction causes - as explained above - a homogenization of the forces to be transmitted between the implant and the bony bearing.
- the flute is in their angle to that of
- Flutes each have a strong positive rake angle. Due to the more favorable compared to the prior art placement of the cutting edges they come in conjunction with the positive rake angle to full advantage and thus cause a significant reduction in the screwing torque and at the same time an increase in overspeeding.
- the invention thus provides a screw-in body with a self-tapping thread with a thread-shaped curved and / or kinked lateral surface and a thread tooth profile tilted in the screwing direction, which due to the opposite direction to the twisting of the thread opposite skew or twist direction of the flute over a much improved screw - and over-spinning behavior and of which a reduction in the loosening rate can be expected.
- the screw-in body according to the invention can be produced without technical problems and without additional time.
