Claims (1)
1. Ortopædisk fastgørelsesindretning (100) dannet ved at: uafhængigt modificere tandhøjde (32), -tykkelse (30) og -afstand (34) og derved ændre fastgørelsesindretningens karakteristika og egenskaber, hvor stigning og store (17) og små tandgevinddiametre er uafhængigt variable for at lette tilpasning af fastgørelsesindretningsgevindprofiler med tilsvarende knogletandprofiler som en funktion af knogledensitet og sted for indsats af fastgørelsesindretning for at forbedre fastgørelsesindretningshold og øge modstand mod udtrækningskræfter, danne en konkav, spiralformet spåntagende spånnot (55) ved en distal ende (4) deraf, hvor den spåntagende spånnot (55) har forreste skærekanter (51), som definerer en skæregevindstruktur anbragt på den distale ende (4), og som snor sig spiralformet i en retning modsat en gevindstruktur (12) anbragt på en resterende del af fastgørelsesindretningen (100), hvor gevindstrukturen (12) anbragt på den resterende del af fastgørelsesindretningen (100) definerer en i det væsentlige ikke-skærende, indbyrdes låsende gevindstruktur, hvor skærenoten (55) er konfigureret til at danne den indbyrdes låsende gevindstruktur i knoglen og derved reducere friktion ved fastgørelsesindretningsindsættelse og minimere varmeopbygning og alt imedens tilvejebringe større følsomhed ved fastgørelsesindretningsinstallation, hvorved installationsvridningsmoment reduceres, anbringe den indbyrdes låsende gevindstruktur spiralformet langs fastgørelsesindretningen (100) afbrudt af et i det væsentlige cylindrisk fastgørelsesindretningsskaft (13), således at fastgørelsesindretningsskaftet (13) definerer en cylindrisk væg, som snor sig spiralformet langs en længde af fastgørelsesindretningen (100) og afbrudt af den indbyrdes låsende gevindstruktur, hvor den indbyrdes låsende struktur og skaftet (13) er konfigurerede til at forsinke vippen af fastgørelsesindretningen (100) og minimere radiale kræfter, medens mangerettede kræfter og bøjningsmomenter modstås, hvilket ellers kunne forårsage hævning af fastgørelsesindretningen, tilvejebringe en anlægsoverflade (6) tilgrænsende en proksimal ende af fastgørelsesindretningen (100), hvilken anlægsoverflade definerer en forhindring for yderligere fastgørelsesindretningsfremrykning og middel til at inducere fastspænding af fastgørelsesindretningen i et ortopædisk miljø, og danne en prespasning tilgrænsende en proksimal ende af fastgørelsesindretningen, hvilken prespasning definerer en forhindring for yderligere fastgørelsesindretningsfremrykning og middel til at inducere fastspænding af fastgørelsesindretningen i et ortopædisk miljø.
