Laite selkärankaluupintojen yhdistämissauvojen säädettävää kiinnitystä varten Anordning för reglerbar fixering av ryggradens benytors kopplingsstavar
Esillä oleva keksintö kohdistuu säädettävään selkärangan instrumenttiin pediku-5 laarista kiinnitystä varten ja tekee mahdolliseksi sovittaa ja uudelleen vakiinnuttaa selkärangan fysiologiset kaaret.
Yleisesti puhuen yhdistetyt pedikkeli-ruuvit istutetaan sauvojen tai levyjen avulla, ruuvin ollessa kaikissa tapauksissa täsmällisesti kohtisuorassa sauvaan tai levyyn 10 nähden.
Hakemusjulkaisusta WO-89/00028 tunnetaan selkärankakiinnitin, jonka ruuvissa on tangon ja ruuvin välisen säädön mahdollistamiseksi pallomainen pää, jolloin tanko ja pallomainen pää lukitaan toisiinsa tangossa olevien muttereiden koverien 15 päiden väliin. Epäkohtana tässä järjestelyssä on se, että siinä joudutaan käyttämään kierretankoa, joka on kallis ja epäedullinen implanttien yhteydessä.
EP-hakemuksesta 330 881 tunnetaan kiinnityselin, jossa on elimet ruuvien ja tangon välistä kulmasäätöä varten. Epäkohtana tässä kiinnityselimessä on se, 20 että ennen kuin tanko kiinnittyy ruuvin päähän, voivat irtonaiset kiinnitysosat hävitä. Toinen epäkohta tässä laitteessa on se, että siinä on kiristettävä kaksi ruuvia ja tangon kulmasäädön hienoviritys vaatii molempien ruuvien perättäistä kiristämistä, mikä puolestaan on hyvin työlästä.
• · · · • « · • · · :1]·. 25 Keksintö pyrkii poistamaan tunnettujen laitteiden haittapuolet ja tarjoaa sauvan- • · · *.···! kiinnityslaitteen, joka mahdollistaa sauvojen säädön pedikkeli-ruuvien akselin • · suhteen.
• · • · · ·> · 1 • · ·
Keksinnön mukaisen laitteen tunnusmerkit on esitetty patenttivaatimuksessa 1.
30 « · φ • · . ·: ·. Tällainen laite tekee mahdollisesti sovittaa kulma, jonka sauva . muodostaa pedikkeli-ruuvin akselin kanssa, erityisesti nuolimaisessa « · 111 1. tasossa, ja sauvan lukitsemisen haluttuun asemaan • · • I · · < i · « t • · • · « ♦ ♦ · 2 102721 lukitusrenkaan avulla, joka deformoi ja lukitsee paikalleen sauvan lukitusruuvin paineen alaisena.
Keksinnön muut tunnuspiirteet ja edut ilmenevät helpommin seuraavasta keksinnön mukaisen laitteen suoritusmuodon kuvauksen lukemisesta, tämän kuvauksen ollessa annettu yksinomaan esimerkkinä ja viitaten oheisiin piirustuksiin, joissa:
Kuvio 1 on räjäytyskuva laitteesta, joka on yhdenmukainen keksinnön kanssa;
Kuvio 2 esittää kuvion 1 mukaisen laitteen, laitteen ollessa kokoonpantuna lukuunottamatta kantta;
Kuvio 3 on leikkaus pitkin keksinnön mukaisen pedikkeli-ruuvin alimmaista tasoa;
Kuvio 4 on keksinnön mukaisen lukitusrenkaan perspektiiviku-vanto:
Kuvio 5 on sivuttainen etukuvanto kuvion 4 mukaisesta renkaasta; ·.· · Kuvio 6 on aksiaalinen 1 eikkauskuvanto keksinnön mukaisesta : : lukitusruuvista; ja ··· • ·
Kuvio 7 on suurennettu kuvanto kuvion 1 mukaisen sauvan ääripäästä.
• · ... Kuvio 1 esittää viitemerkil lä 1 tunnetun tyyppistä pedikkeli-• · · • · · *. ruuvia. Se sisältää kartiomaisen ruuvin 2, suipon kärjen 3 ja • · äänirautamuotoisen sylinterimäisen pään 4, joka on lävistetty kummaltakin sivulta. Vielä yksityiskohtaisemmin pää 4 sisältää ; .·. kaksi vastakkaista yhdensuuntaista haaraa 4a ja 4b, jotka koi- 3 102721 lektiivisesti määrittävät simpukan kuorirakenteen tai pesän 5, jonka pääakseli on kohtisuorassa ruuvin 2 akseliin nähden ja kykenee vastaanottamaan olennaisesti sylinterimäisen muotoisen sauvan tai yhdistämiselementin 6. Sellainen rakenne on hyvin tunnettu ja kuvattu esim. julkaisussa GB-2.173.104.
Haarojen 4a ja 4b vastakkaiset sisäpuoliset pinnat ovat sylin-terimäisiä ja kierteitetyt siten, että ne vastaanottavat luki-tusruuvin 7 sauvan 6 lukitsemiseksi pesäänsä 5 samalla tavoin kuin ruuvilukituslaite, joka on kuvattu julkaisussa EP- 0.010.527.
Pää 4 vastaanottaa hatun 8, joka peittää haarojen 4a ja 4b ylemmät ääripäät.
Keksinnön mukaisesti sauvan 6 lukitseminen on varmistettu lukitusrenkaan 9 avulla, joka kykenee liukumaan vapaasti sauvaa 6 pitkin vastaanotettuna pesässä 5 ja lukittuna lukitusruuvin 7 avulla.
Rengas 9, lukitusruuvin 7 ääripää ja pesän 5 osa, joka on ·' kosketuksissa renkaan 9 kanssa, on tehty mukautumaan toisiinsa erityisellä tavalla.
Esitetyssä suoritusmuodossa rengas 9 sisältää (kuvio 4) ulko-puolisen pallomaisen kuperan pinnan 10, joka on yhteistoimin- • · ***. nassa ensiksi pallomaisen koveran pinnan 11 (kuvio 6) kanssa, !..* joka on järjestetty lukitusruuvin 7 kartiomaisen osan ääripää- • · · *·' * hän, ja toiseksi pallomaisen koveran pinnan 12 (kuvio 3) kanssa, joka on järjestetty sauvan 6 vastaanottavan pesän 5 pohjalle, haarojen 4a ja 4b väliin.
• · · • · · • · · .·!·. Rengas 9 on sijoitettu siten, että sen taso on likimäärin • · · .···. kohtisuorassa (kuvio 2) ruuvin 1 nuolimaisen tasoon, joka on määritetty ruuvin akselilla 13 ja sauvan 6 vastaanottavan pesän • · 4 102721 5 pääakseli1 la.
Rengas 9 on varustettu suoralla raolla 14 (kuviot 4 ja 5) ja sillä on yksi sisäpuolinen sylinteripinta 15, joka on juuri hieman suurempi kuin sauvan 6 halkaisija.
Sauva 6, jonka päälle rengas 9 on sovitettu, on asennettu pedikkeli-ruuvin 1 pesän 5 sisäpuolelle sen jälkeen, kun tämä ruuvi on asennettu tarkoituksenmukaiseen luuosaan. Rengas 9 tartutetaan pesään 5, 12, kuten esitetty kuviossa 2, sitten lukitusruuvi 7 kierretään haarojen 4a ja 4b väliseen tilaan. Ennen renkaan 9 lukitsemista hattu 8 sijoitetaan yksinkertaisesti tartuttamalla hajareisin kahden haaran 4a ja 4b yli, sitten sauva 6 suunnataan sopivasti nuolimaisen tason sisäpuolella (kuvio 2) ja lukitaan haluttuun suuntaukseen puristamalla lukitusrengas 9 lukitusruuvin 7 kanssa. Sauvan 6 kulmavälys on esimerkiksi 15° ruuvin 1 akseliin 13 nähden kohtisuoran aseman ympärillä, kuten esitetty kuviossa 2.
Sovitettaessa sauvaa 6 rengas 9 liukuu sauvaa rajoittavien pallomaisten pintojen 11 ja 12 yli.
Sauvan 6 vapaan kulmavälyksen sallimiseksi pesän 5 pohja oikealle kahdesta vastakkaisesta sisäänmenosta on loivasti i syvennetty kohdassa 15 (kuviot 2 ja 3), lukitusruuvin kärjen typistetyn osan 16 (kuvio 6) varmistaessa sauvan vapaan ·:··· välyksen lukitusruuvin puolelta.
• · · • · « • · ·
Hattu 8 sisältää (kuvio 2) kaksi vastakkaista pykälää 17 sauvan 6 vapaata välystä varten ja keskilävistyksen 18 vääntötyökalun • · ... läpikulkua varten, kuten esimerkiksi kuusikulmainen väännin, • · · *. lukitusruuvin 7 kiristämiseksi onton kuusikulmaisen syvennyksen • · 19 avulla, joka on järjestetty mainitun ruuvin 7 yläpintaan.
: .·. Hatun tehtävä on pääasiassa välttää kahden haaran 4a ja 4b # * • · 5 102721 etääntymistä toisistaan kiristettäessä lukitusruuvia. Hattu 8 voi olla poistettu, mikäli ruuvin 1 materiaali tai haarojen 4a, 4b koko, erityisesti sen paksuuden suhteen, sallii sen.
Lukitusruuvin 7 läpikotainen kiristäminen aikaansaa sauvan 6 lukittumisen renkaan 9 avulla valittuun asemaan, aukon 14 ollessa edullisesti sijoitettu sivuttain, kuten esitetty kuviossa 2.
Sauva on täten täysin lukittu, sekä sen suuntauksen suhteen ja sen pyörimisen akselinsa ympäri, suhteen.
Sauva 6 voi esimerkiksi olla tasainen yhdistämiselementti, joka on järjestetty kahdessa ääripäässään ontolla kuusikulmaisella syvennyksellä (kuvio 7) tai jopa elementti, joka on muodostettu joustavista palmikoiduista sylinterimäisistä nauhoista.
Järjestämällä reiät tai syvennykset 20 tämä sallii vastaavan-laisesti muodostetun vääntöavaimen sisäänjohtamisen tarkoituksena vaikuttaa selkärangan pyörimisen estämiseen.
*· Itse asiassa vaikuttamalla vääntimien avulla pyörimiseen samaan suuntaan sauvan 6 akselilla, tämä sauva saatetaan pyörimään ja i vastaavasti selkäranka pyörii pitkin sen pystysuuntaista akselia.
• · · • · *···] Lopuksi keksintö ei selvästikään ole pelkästään rajoitettu edellä esitettyyn suoritusmuotoon vaan kattaa kaikki mahdol- • · · *.* * liset variaatiot, erityisesti, mitä tulee kuperien ja koverien pintojen muotoon ja sijaintiin renkaassa 9 ja vastaavasti pin- *:·*: noissa 11 ja 12, joiden väliin se on ruuvattu ja mitä tulee lukitusruuviin 7, joka voidaan ruuvata vastakkaisiin haaroihin .\f 4a ja 4b tai kappaleeseen, joka on asennettu ruuvin päähän 4.
• · · λ! Vastaavasti renkaan 9 ja raon 14 muoto ja dimensio voi myös • « ·;· vaihdella poikkeamatta keksinnön yhteydestä siihen laajuuteen, • « 6 102721 että toimii samassa tehtävässä renkaan elastiseksi lukitsemiseksi pusertamalla se lukittavan sauvan päälle.
Lisäksi sauvan 6 ääripäät voivat sisältää yleisesti sisäpuolisen tai ulkopuolisen kulmamuodon, kuten esitetty kuviossa 7, tämän muodon ääriviivan voidessa olla mikä tahansa haluttu, kuten monikulmainen varustettuna n sivulla, ja sopivasti sovitettu vääntötyökalun ulkomuotoon, mikä sallii sauvan 6 pyörittämisen akselinsa ympäri.
