Clip-like implant for osteosynthesis
View Patent ↗The invention relates to a clip-like implant for osteosynthesis of at least two repositioned bone fragments, with at least two retainer web sections and with one connection web section connecting the retainer web sections, wherein the free ends of the at least two retainer web sections can be at least partially fixed in a respective one of the two repositioned bone fragments. Advantageously the clip-like implant has a C-shaped cross section, in which the first and second retainer web sections each enclose with the connection web section an angle (w, w′) between 75° and 90°, and the free ends of the at least two retainer web sections are designed as inwardly directed points.
1. A surgical clip-like implant for osteosynthesis of at least two repositioned bone fragments comprising first and second retainer web sections and with one connection web section connecting the first and second retainer web sections, the connection web section comprising a break line facilitating separation of the surgical clip-like implant fixed in the bone fragments as the separated surgical clip-like implant may be easily removed, the break line being composed of a portion of smaller cross sectional area formed along the connection web section when viewed along a plane perpendicular to a longitudinal axis of the connection web section, the break line including first and second lateral recesses formed along opposed lateral sides of the connection web section and top and bottom recesses formed along top and bottom walls of the connection web section defining the portion of smaller cross sectional area, wherein free ends of the first and second retainer web sections can be at least partially fixed in a respective one of the two repositioned bone fragments wherein the surgical clip-like implant has a C-shaped cross section and is manufactured of a wire material, the first and second retainer web sections each enclose with the connection web section an angle between 75° and 90°, and that the free ends of the first and second retainer web sections are inwardly directed points.
2. The surgical clip-like implant according to claim 1 wherein, the connection web section is slightly curved.
3. The surgical clip-like implant according to claim 1 , wherein the connection web section merges on its two ends into the first and second retainer web section.
4. The surgical clip-like implant according to claim 1 , wherein a length of the connection web section is selected based on dimensions of the bone fragments to be fixed.
5. The surgical clip-like implant according to claim 1 , wherein a length of the first and second retainer web sections is selected based on dimensions of the bone fragments to be fixed or based on a thickness of the bone wall of the bone fragments to be fixed.
6. The surgical clip-like implant according to claim 1 , wherein the surgical clip-like implant is comprised of a body-compatible metal, a metal alloy, a plastic or a combination thereof.
7. The surgical clip-like implant according to claim 1 , wherein a thickness of the material used for manufacture of the surgical clip-like implant is selected based on the dimensions of the bone fragments to be fixed or based on a thickness of the bone wall of the bone fragments to be fixed.
8. The surgical clip-like implant according to claim 1 , wherein the surgical clip-like implant is driven with the free ends of the first and second retainer web sections into the opposing repositioned bone fragments so that the connection web section extends approximately perpendicular to the fracture line.
9. The surgical clip-like implant according to claim 1 , wherein the surgical clip-like implant is used for minimal invasive surgical procedures.
10. The surgical clip-like implant according to claim 1 , wherein the surgical clip like implant is adapted to a surface of the bone fragment or a surface of the bone wall.
11. The surgical clip-like implant according to claim 1 , wherein the first and second retainer web sections are retaining rivets, which can be inserted into bore holes provided in the hone fragment.
12. An arrangement for osteosynthesis of at least two repositioned bone fragments comprising at least two surgical clip-like implants as claimed in claim 1 , wherein the at least two surgical clip-like implants are driven into respectively opposing repositioned bone fragments so that the surgical clip-like implants cross each other.
13. The arrangement according to claim 12 , wherein the connection web sections of the at least two surgical clip-like implants enclose an angle (α) between 30° and 90°.
14. An arrangement for driving in at least one surgical clip-like implant, as claimed in claim 1 , into at least two repositioned bone fragments with the free ends of the first and second retainer web sections of the surgical clip-like implant ahead into the at least two repositioned bone fragment to be stabilized, the arrangement also including a staple unit wherein the staple unit additionally comprises a drilling function for creating bore and guide holes in the at least two repositioned bone fragments.
15. The arrangement according to claim 14 , further comprising a magazine unit for holding several surgical clip-like implants.
16. A surgical clip-like implant for osteosynthesis of at least two repositioned bone fragments comprising first and second retainer web sections and with one connection web section connecting the first and second retainer web sections wherein free ends of the first and second retainer web sections can be at least partially fixed in a respective one of the two repositioned bone fragments wherein the surgical clip-like implant has a C-shaped cross section, the first and second retainer web sections each enclose with the connection web section art angle between 75° and 90°, and that the free ends of the first and second retainer web sections are inwardly directed points, and wherein the connection web section comprises a break line facilitating separation of the surgical clip-like implant fixed in the bone fragments as the separated surgical clip-like implant may be easily removed, the break line being composed of a portion of smaller cross sectional area formed along the connection web section when viewed along a plane perpendicular to a longitudinal axis of the connection web section, the break line including first and second lateral recesses formed along opposed lateral sides of the connection web section and top and bottom recesses formed along top and bottom walls of the connection web section defining the portion of smaller cross sectional area.
17. The surgical clip-like implant according to claim 16 , wherein the connection web section is slightly curved.
18. The surgical clip like implant according to claim 16 wherein a length of the first and second retainer web sections is selected based on dimensions of the bone fragments to be fixed or based on a thickness of the bone wall of the bone fragments to be fixed.
19. The surgical clip-like implant according to claim 16 , wherein the surgical clip-like implant is comprised of a body-compatible metal, a metal alloy, a plastic or a combination thereof.
