Abstract
A device for treating bone fractures and/or for fixing surgical implants, surgical threads or tissues in or on the bone comprising a closing element and a rivet. The rivet includes a shaft extending from a rear end to a front end coaxial to a central axis and having a through-hole extending coaxially therethrough. The shaft of the closing element is coaxially displaceable in the through-hole and the head of the closing element can be axially brought to rest on the front shaft end. The rivet also comprises at least two grooves on the outside, these grooves extending from the front shaft in the direction of the rear end, parallel to the central axis.
Claims10
A device for fixing surgical implants with a rivet, the rivet comprising:
- a rivet shaft extending from a rear end to a front end coaxial to a central axis and having an outer circumferential surface, the rear end intersecting the central axis and the front end positioned axially opposite the rear end, the rivet having a through-hole extending coaxially therethrough, and at least two grooves extending along the outer circumference from the front end toward the rear end and parallel to the central axis over a length L, the grooves having a radial depth t measured from the outer circumferential surface,
- wherein the rivet is formed from a material having the characteristic of the ratio of tensile strength to elongation at break of between 10:1 and 50:1.
