Description

505 112 2 l0 l5 20 25 30 35 igenom tätt ingrepp av åtminstone partier av pluggens utsida med och i hålväggen. Ivridningen göres tills pluggens storändyta ligger i plan med skallbenet.
Det skall noteras att man t ex i tandimplanterings- sammanhang redan korrigerat för felborrningar genom an- vändning av ökande borrdiametrar efter varandra, men sådana tidsödande åtgärder står inte till förfogande vid operation i skallen, t ex efter hjärnblödning.
Vridning av huvudfria pluggar i kroppshåligheter är också i och för sig känd, men endast, vad sökanden känner till, i samband med pluggar vars stomme uppvisar gängor, se t ex EP-A-469 441 och DE-A-35 05 567, och som är av- sedda som fastsättningsskruvar för implantat eller är rät-cirkulärcylindriska. Sådana skruvar ger inte den med uppfinningen eftersträvade raspningseffekten.
Pluggen enligt uppfinningen kan bestå av vilket som helst osseointegrerande eller biokompatibelt material, av vilka det för närvarande mest föredragna är titan.
Framställning av pluggen enligt uppfinningen kan t ex ske genom formgjutning av titan.
Det är underförstått att tvärdimensionen av pluggen skall anpassas till det borrade hålets tvärdimension så att ovan beskrivna raspeffekt kommer till stånd, varvid kirurgen tillhandahålles pluggar med olika grundmått.
Utskotten har en längd, utgående från stommen och radiellt utåt, och bredd, ningen, på högst 1,5 mm, eftersom större längder och tvärs mot den nämnda rikt- bredder kan skapa problem med beninväxt till pluggens stomme och med invridningen av pluggen.
För bäst vävnadinväxt mot stommen bör utskotten vara underskurna, dvs ha relativt smal bas vid stommen. De kan t ex vara korn- eller kulformiga.
Ett utföringsexempel på uppfinningen visas på bifo- gade ritning i längdsektion.
En av titan bestående, rak-konisk, symmetrisk, huvudlös plugg 1 för insättning i skallen efter en opera- tion däri har måtten stordiameter 7 mm, lilldiameter 6 mm 3 585 112 och höjd 4 mm, varvid diameteruppgifterna inkluderar 0,6 mm o kulformiga utskott 2 på en stomme 3, vilka utskott är oregelbundet fördelade på stommens mantelyta. I stor- ytan av pluggen finns en fyrkantsfordjupning 4 för an- grepp av pluggen för vridning medelst en fyrkantsnyckel.
