Description

Dessa nya system har emellertid den nackdelen att de är otympliga och utrymmeskrävande, och de inte är så enkla att handha då ofta mint två skruvar krävs för att fästa elementen vid varandra. Det är svårt att med dessa system skruva in skruvarna i ett vinklat läge mot metallplattan för att inkludera ett viktigt benfragment i osteosynthesen och i alla fall sitta fast i plattan.
Kort redogörelse av uppfinningstanken Föreliggande uppfinning har till uppgift att undanröja ovannämnda problem och nackdelar vid sammanfogning och fixering av två element med varandra med en skruv eller liknande oberoende av skruvens axiella eller vinkel position.
I enlighet med uppfinningsidén löses ovannämnda problem genom att nämnda första element har ett sfäriskt hål i vilket en formbar hylsa är anordnad i form av en ringhylsa, vilken är uppdelad i segment, flänsar, och som har en sfärisk form som passar in i hålets sfäriska form och vilken ringhylsa har en koniskt gängad inre form vilken är komplementär mot skruvhuvudets yttre gängade form varvid skruven vid inskruvningen fäster det första elementet i önskad valfri vinkel mot det andra elementet (9) och fixerar skruvförbandet i detta läge.
Kortfattad beskrivning av bifogade ritningar Figur 1 visar en, i anordningen enligt föreliggande uppfinning, ingående platta, företrädesvis av metall, sedd framifrån. 53% 53? Figur 2 visar plattan i figur 1 sedd från sidan i genomskärning längs snitt A-A i figur 1.
Figur 3 visar en, i anordningen enligt föreliggande uppfinning, ingående sfärisk, formbar och slitsad hylsa sedd från sidan i perspektivvy.
Figur 4 visar den sfäriska, slitsade hylsan i figur 3 sedd underifrån i horisontalvy.
Figur 5 visar den sfäriska hylsan sedd från sidan i vertikalvy.
Figur 6 visar den sfäriska hylsan sedd från sidan i genomskärning i vertikalvy med en skruv vars yttre gängade, koniska huvud är inskruvad ända in i hylsans inre koniska gängade del.
Figur 7 visar den övre delen av skruven med konisk skalle ingående i anordningen enligt föreliggande uppfinning sedd från sidan i perspektivvy.
Figur 8 visar hela skruven i figur 7 sedd från sidan i perspektivvy.
Figur 9 visar skruven i figur 8 sedd uppifrån i horisontalvy.
Detajerad beskrivning av en föredragen utföruingsform av uppfinningen I figurerna l och 2 visas en, i anordningen enligt föreliggande uppfinning, ingående platta 1, företrädesvis av metall. Plattan l har ett sfäriskt hål 2.
I figurerna 3,4,5 visas en hylsa 3, också av metall, sfärisk till formen med uppslitsade spår 4 med en kvarlämnande tunn förbindelse mellan de uppkomna flänsarna.
Denna förbindelse 6 tillåter, utan att deformeras, flänsarna 5 att buktas in så att hylsan 3 kan klämmas in i plattans l sfäriska hål 2. Hylsan 3 hålls på plats inne i det sfäriska hålet 2 när flänsarna 5 återtar si normala form. Hylsans 3 sfäriska form gör att den till viss gräns kan uppta sneda inställningar. Hylsan 3_är till större delen konisk till formen och blir cylindrisk i dess nedre del. Insidan av hylsans 3 koniska del är försedd med gänga ll.
I figur 6 visas den sfäriska hylsan 3 sedd från sidan i genomskärning i vertikalvy med en skruv 7 som har ett koniskt huvud 8 med en gänga 12. Vid slutdragning av skruven 7 tar denna gäng med hylsans 3 gänga ll, samtidigt som den uppslitsade hylsan 3 expanderar och låser hylsan mot hålets 2 sfär i plattan 1.
I figurerna 7,8 och 9 visas skruven 7 med sitt koniska huvud 8 med gängor 12 med liten stigning i förhållande till skruvens 7 nedre del som har något större gängor med större stigning för lämplig fixering i benvävnad.
När de två elementen skall sammanfogas med varandra med en anordning enligt uppfinningen för att fästa det första elementet 1 med det andra elementet 9 medelst en skruv 7, för man skruven 7 in genom hylsan 3 så långt att det nuddar det andra elementet Därefter bestämmer man den riktning på skruven 7 som man önskar, fortsätter sen indrivningen av skruvens 7 nedre gänga 14 in i det andra elementet 9.
Slutdragningen sker när skruvskallens 8 gänga 12 totalt fyller ut den koniska gängan ll i hylsan 3.

PATENTKRAV
1. Anordning för att vid kirurgisk användning av skruvförband, fästa och fixera ett första element t.ex. i form av ett implantat mot ett andra element t.ex. i form av en benvävnad medelst en skruv med dels ett koniskt huvud med konen mot skruvspetsen och vilket huvud har en utvändig gänga med liten stigning vilken är avsedd att skruvas in i det första elementet, och dels en huvudgänga på skruvens stam vilken är avsedd att skruvas in i det andra elementet, kännetecknad av att nämnda första element (1) har ett sfäriskt hål (2) i vilket en formbar hylsa (3) är anordnad i form av en ringhylsa (3), vilken är uppdelad i segment, flänsar, (5) och som har en sfärisk form som passar in i hálets (2) sfäriska form och vilken ringhylsa (3) har en koniskt gängad inre form vilken är komplementär mot skruvhuvudets (8) yttre gängade form varvid skruven (7) vid inskruvningen fäster det första elementet (1) i önskad valfri vinkel mot det andra elementet (9) och fixerar skruvförbandet i detta läge.
2. Anordning enligt kravet 1, kännetecknad av att ringhylsan,(3) innefattar en tunn ringformig del (6) vilken sammanbinder segmenten, flänsarna, (5) och underlättar införandet av hylsan (3) i det sfäriska hålet (2) i det första elementet (1).
