Description
510 358 10 15 20 25 30 35 hålan kan vara trängre vid ingången än längst ned förmår inte hylsan centrera helt utan snarare förhindrar att man hamnar längst uti någon kant.
Uppfinningens funktion är att packa malet bentransplantat homo- gent och likformigt runt väggarna i den håla i lårbenet där det ti- digare protesskaftet suttit.
Uppfinningen består av tre delar, dels ett metallstift med konisk gänga i ena änden, dels en lång metallhylsa som träs över stiftet.
Denna hylsa har i sin nedre ände några fjäderstål som ”spretar ut" från hylsan. Syftet med fjäderstålen är att då hylsan förs ned i làrbenshålan fungerar fjäderstålen så att de centrerar hylsan samt stiftet som därefter kan gängas ned i lårbenet varefter hyl- san dras ut och stiftet sitter alltså centrerat i botten på hålan.
Alternativt används stiftet utan hylsa genom att man på stiftet skruvar fast en s k fjäderplugg som då tjänar till att centrera stif- tet.
Nästa moment är att fylla hålan med malet bentransplantat som normalt är blandat med en vätska bestående av vävnadsvätska såsom blod och vatten samt fett. Då hålan är fylld med trans- plantatet tar man uppfinningens tredje komponent som är en ko- nisk hylsa med ett hål i nedre änden som träs över stiftet. Hylsan är försedd med en stor mängd mycket små hål på sidorna samt ett skaft i övre änden som används när hylsan slås ned i ben- transplantatet varvid benet packas åt sidorna och överflödig vätska bortförs via hålen till utrymmet inne i hylsan och kan su- gas undan. " Under hänvisning till bifogade ritningar följer nedan en närmare beskrivning av ett som exempel anfört utförande av uppfinningen.
På ritningarna är Fig 1 en sidovy av ett i anordningen ingående styrstift, 10 15 20 25 30 35 510 358 Fig 2 en sidovy av en hylsa för centrering av styrstiftet i ett hål- rum i ben, Fig 3 en sidovy av ett packningsorgan, Fig 4 en vy visande packningsorganet enligt fig 3 betraktat från vänster i fig 3, Fig 5 en vy visande styrstiftet och dess centreringshylsa in- förda i ett hålrum i ben och Fig 6 en vy illustrerande packningsorganet i nämnda hålrum, varvid packningsorganet styrs av styrstiftet och benväv- nadsmaterial packats kring packningsorganet.
Uppfinningen innefattar ett stift 1 som har en konisk gänga 4 med sådan storlek att den passar på en fjäderplugg. Fjäderpluggen används normalt till att placeras en bit inne i märghålan och av- gränsa det utrymme som fyllts med cement. I min uppfinning kan stiftet och fjäderpluggen även tjäna till att centrera stiftet. Ett alternativ är att trä hylsan 2 med fjäderstålen 8 runt stiftet 1, var- vid fjäderstålen centrerar stiftet som därefter skruvas fast i märghålan i botten på revisionshålan.
Hålan fylls med bengröt varefter "benpackarhylsan“ 12 pressas ned över stiftet 1, pressar bentransplantatet åt sidorna och släpper in överflödig vätska i hylsan där vätskan kan sugas bort.
Proceduren upprepas med att hylsan dras ur, nytt ben fylls på i hålan varefter hylsan slås ned igen tills man har fått en tillräckligt hård packning av bentransplantatet mot corticalt ben varefter stiftet avlägsnas. Man för ned bencement i hålan och därefter en ny femurstam som cementeras fast.
En alternativ användning är i de fall där man på grund av infek- tion eller alltför skört ben vill göra en s k tvåstegsoperation där man först bentransplanterar, avslutar operationen och under 510 358 10 15 20 25 några veckors väntan låter bentransplantatet läka in varefter man gör en ny operation och då cementerar fast proteskompo- nenten. I detta fall efter att ha avslutat bentransplanteringen på samma sätt som ovan fylls hålan med en "spacer" av samma yt- termått som benpackarhylsan. Spacern tillverkas före opera- tionen genom att man först gör en avgjutning av benpackaren av gipsbindor och därefter gör en avgjutning i bencement av den håla man fått i gipset efter benpackaren. Vid operation nummer två avlägsnas bencementspacern varefter man cementerar en femurstam i hålan.
SAM MAN FATTNING Vid Ortopedkirurgiska operationer där man behöver byta ut en konstgjord höftled kan det finnas behov av att bentransplantera i den håla där femurkomponent och eventuellt bencement suttit i lårbenet.
Min uppfinning innehåller tre delar med vars hjälp man kan packa ett homogent lager av bentransplantat inne i hålan. Därefter ce- menterar man antingen fast en ny femurskomponent mot ben- transplantatet i samma operation eller placerar in en ”spacer” vil- ken kan avlägsnas vid nästa operation då transplantatet läkt in och man har en lagom håla att cementera en ny femurkomponent |.
Claims (6)
1. Anordning för användning vid transplantation av benvâvnadsmate- rial i ett hålrum (7) i ben i ändamål att ge hålrummet åsyftad form med erforderlig tjocklek hos benmaterialet som bildar hålrummets vägg, varvid anordningen innefattar ett organ (3) för packning av benväv- nadsmaterialet i hålrummet, kännetecknad därav, att packningsorga- net (3) innefattar en hylsa (12), som avgränsar ett inre utrymme (13), och att hylsan är försedd med hål (16) för att tillåta vätska att från det omgivande benvàvnadsmaterialet passera genom hylsan in i utrym- met.
2. Anordning enligt krav 1, kännetecknad därav, att den dessutom in- nefattar ett styrstift (1) och att packningsorganet (3) uppvisar en öpp- ning (10) för genomträde av styrstiftet för att uppnå att packningsorga- net under rörelse relativt styrstiftet styrs av detta.
3. Anordning enligt krav 2, kånnetecknad av en hylsa (2) för centre- ring av styrstiftet (1) i hålrummet.
4. Anordning enligt krav 3, kånnetecknad därav, att centreringshylsan (2) är ingripbar med styrstiftet (1) och innefattar fjäderstål (8) anord- nade att anligga mot hålrummets vägg.
5. Anordning enligt krav 1, kånnetecknad därav, att styrstiftet (1) in- nefattar en gänga (4) för inskruvning i benet.
6. Anordning enligt något av kraven 1-5, kännetecknad därav, att styrstiftet (1) är utformat för fastskruvning av en fjàderplugg, som tjä- nar till centrering av stiftet.
