MODULARNE STRANSKE NAPRAVE Z INTRAMEDULARNIM ŽEBLJEMMODULAR SIDE DEVICES WITH INTRAMEDULAR TOWN
ZA VODENJE KOSTI PRI POSTOPKU NJENEGA PODALJŠEVANJATO GUIDE BONE IN THE PROCEDURE OF ITS EXTENSION
Predmet izuma [001] Predmet izuma je izboljšava modularne stranske naprave z intramedulamim žebljem za vodenje kosti, zlasti stegnenice ali golenice pri postopku njenega podaljševanja. Naprava sestoji iz zunanjega kostnega fiksaterja, notranjega kostnega fiksaterja (intramedularnega žeblja) in veznih elementov.The object of the invention is the improvement of a modular lateral device with an intramedullary nail for guiding the bone, especially the femur or tibia, in the process of its extension. The device consists of an external bone fixator, an internal bone fixator (intramedullary nail) and attachment elements.
Tehnični problem [002] Tehnični problem, ki ga rešuje izum je, kako izboljšati opisano napravo v območju njene povezave z obema deloma prerezane kosti pri večmesečnem zdravljenju, in sicer zato, da bo vijačni spoj med napravo in vsakokratnim delom prerezane kosti kakovosten pri silah, ki nastopajo pri zaraščanju podaljšane kosti in omejenem prostoru v obeh delih kosti za uvijanje vijakov, upoštevajoč prisotnost notranjega kostnega fiksaterja, ki se nahaja v kostnem kanalu obeh delov prerezane kosti in zunanje oblike kosti pri sklepu, pri čemer naj tak vijačni spoj bistveno zmanjša možnost za prehod bakterij s kože skozi kožno luknjo, skozi katero teče ves čas podaljševanja del naprave.prekoTechnical Problem [002] The technical problem to be solved by the invention is how to improve the described device in the area of its connection with the two partially cut bones during months of treatment, so that the screw joint between the device and each part of the cut bone is of good quality at forces, occurring in the overgrowth of the extended bone and the limited space in both parts of the bone for twisting the screws, taking into account the presence of an internal bone fixator located in the bone canal of both the sectioned bone and the outer shape of the bone at the joint, with such a screw joint significantly reducing the possibility of the passage of bacteria from the skin through the skin hole through which part of the device flows throughout the extension
Antolič-4/X-12/Vr zunanjega fiksaterja v kost in, kar je še huje celo do kostnega kanala in po njem v vsej njegovi dolžini. Okužba zahteva takojšnje ukrepanje, tudi operativno, ki pa povzroči izredne težave ali celo prekinitev postopka podaljševanja kosti. Zato je zmanjšanje možnosti okužbe pri postopku podaljševanja kosti tako pomembno za dosego visoke uspešnosti tovrstne operacije.Antolich-4 / X-12 / Vr external fixator into the bone and, even worse, even to and through the bone canal along its entire length. The infection requires immediate action, including surgery, which in turn causes extreme problems or even interruption of the bone extension process. This is why reducing the chances of infection during the bone lengthening process is so important to achieve the high success rate of this type of surgery.
Znano stanje tehnike [003] Naprava, ki je predvidena za izboljšavo, je zasnovana kot stranski zunanji in vzdolžno zvezno podaljšljiv sklop, ki je z vsakim svojim koncem povezan v prečni smeri z vsakim delom prekinjene kosti, pri čemer sta oba dela kosti osno vodena z intramedulamim žebljem, ki leži koaksialno v kanalih obeh delov kosti, in ki je sicer zapolnjen s kostnim mozgom. Najpogosteje se podaljševanje kosti izvaja na stegnenici. Sicer je napravo z izboljšavo po izumu možno prirediti za uporabo na drugih kosteh samo z morebitnimi dimenzijskimi spremebami naprave z izboljšavo po izumu, upoštevajoč morfologijo obravnavane kosti.BACKGROUND OF THE INVENTION [003] The device to be improved is designed as a lateral outer and longitudinally lengthening assembly, which is connected at each end in a transverse direction to each part of the broken bone, both axially guided by an intramedullary nail, which lies coaxially in the ducts of both parts of the bone, and which is otherwise filled with bone marrow. Most often, bone extension is performed on the femur. Otherwise, the enhancement device according to the invention can be adapted for use on other bones only with the possible dimensional changes of the enhancement device according to the invention, taking into account the morphology of the bone in question.
[004] V nadaljevanju bomo kot primer uporabe opisane naprave z izboljšavo po izumu vzeli stegnenico, ki je najpogostejša kost za tovrstno podaljševanje. Ker je kost nepravilne oblike in se dimenzijsko razlikuje od pacienta do pacienta, zlati na prehodu v odebeljeni del kolenskega sklepa, v bližini katerega se tudi najpogosteje izvaja podaljševanje kosti, obstaja potreba po izboljšavi povezave zaradi odprave pomankljivost dosedanje izvedbe, da se odpravijo ali bistveno zmanjšajo opisane težave med postopkom podaljševanja kosti, kot so opisane v tehničnem problemu.[004] In the following, we will take the femur, which is the most common bone for this kind of extension, as an example of the use of the described improvement device according to the invention. Because the bone is irregular in shape and dimensionally different from patient to patient, golden at the transition to the thickened knee joint, near which bone extensions are most commonly performed, there is a need to improve the connection to eliminate deficiencies so far to eliminate or significantly reduce described problems during the bone lengthening process as described in the technical problem.
Rešitev tehničnega problema [005] Opisani tehnični problem je rešen z izboljšavo opisane naprave v območju njene vijačne povezave z vsakokratnim delom kosti, ki je v postopku podaljševanja. Značilnost povezave po izumu je v tem, da je za vsak delSolution to a Technical Problem [005] The technical problem described is solved by improving the described device in the area of its screw connection with each part of the bone undergoing extension. A feature of the invention according to the invention is that it is for each part
Antolič-4/X-12/Vr prekinjene kosti predviden vmesni prilagodno povezovalni element, ki je na eni strani vijačno nameščen na kost, upoštevajoč morfološke značilnosti kosti vsakokratnega pacienta, ter v odmiku od te vijačne povezave vijačno spojen z vijaki, prednostno dvema, ki potekajo prečno na vzdolžno os kosti, in ki so na drugi strani vpeti v spono, ki je vpeta v en konec aksialno podaljšljivega zunanjega sklopa. Ker se običajno izvaja podaljševanje blizu kolenskemu sklepu, je prilagodno povezovalni element zasnovan tako, daje prirejen morfologiji dela kosti z uvedbo prilagodnega elementa, na katerega nalega in sicer tako, da po namestitvi vmesnega povezovalnega elementa ležijo vijačne izvrtine v njem in sicer za povezavo s spono zunanjega podaljšljivega sklopa naprave, medsebojno vzporedno. Nadalje je vmesni povezovalni element izveden z zaseki in/ali izvrtinami, ki so predvideni za sprejem kostnih vijakov, pri čemer zaseki in/ali izvrtine omogočajo usmeritev posameznega kostnega vijaka v sredico kosti, ki jo opredeljujeta njena zunanja površina in površina njenegs kanala, v katerem se med postopkom podaljševanja kosti nahaja intramedulami žebelj. Pri drugi povezavi na drugem delu kosti je predviden v skladu z operatino metodo poleg vseh zgoraj naštetih vijakov še vijak na povezovalnem elementu, ki teče prečno skozi celotno kost in skozi izvrtino v intamedulamem žeblju, ki se nahaja v kostnem kanalu. S tem je aksialno fiksiran intramedulami žebelj, kot predvideva operativna metoda.Antolich-4 / X-12 / Vr discontinuous bone envisaged intermediate adaptive connecting element, which is screwed to the bone on one side, taking into account the morphological characteristics of the bone of the respective patient, and screwed, apart from this screw connection, by screws, preferably two, which they extend transversely to the longitudinal axis of the bone, and which, on the other hand, are clamped into a clamp that is clamped to one end of an axially extensible outer assembly. As the extension is usually performed near the knee joint, the adaptive connecting element is designed to adapt to the morphology of the bone by introducing an adaptive element, such that, after mounting the intermediate connecting element, there are screw holes in it for connection with the clamp external extension assembly of the device, parallel to each other. Further, the intermediate connecting element is provided with notches and / or holes intended for receiving bone screws, wherein the cuts and / or holes allow the individual bone screw to be directed to the bone core defined by its outer surface and the surface of its canal, in which there is an intramedullary nail during the process of bone extension. In the case of a second joint on the other part of the bone, in accordance with the operative method, in addition to all the above screws, a screw is provided on the connecting element that runs transversely through the entire bone and through a hole in the intamedullary nail located in the bone canal. This secures the axial intramedullary nails as predicted by the operative method.
[006] S tem je zagotovljen mehansko močen vijačni spoj, ki je nujno potreben med postopkom podaljševanja kosti.[006] This provides a mechanically strong screw connection that is absolutely essential during the bone extension process.

[008] Modularna stranska naprava z intramedulamim žebljem za vodenje kosti, zlasti stegnenice ali golenice pri postopku njenega podaljševanja, vključno z njeno izboljšavo, je v osnovi izvedena iz zunanjega podaljSevalnega elementa[008] A modular lateral device with an intramedullary nail for guiding the bone, especially the femur or tibia, in the process of its extension, including its enhancement, is essentially derived from an external extension element
I, ki poteka po zunanji strani uda vzporedno s kostjo 2, ki je prerezana na mestu 2a, kjer je predvidena za podaljšanje. Na vsakem koncu elementa 1 se nahaja po ena spona 3, v kateri sta vpeta prečno na njeno vzdolžno os po dva paličasta vijaka 4 s protimatico. V kanalu 5 prekinjene kosti 2 se nahaja intramedulami žebelj 6, ki vodi oba dela kosti 2 tako, da sta podaljšljivi osni smeri.I extending along the outside of the limb parallel to the bone 2, which is cut in position 2a where it is intended to be extended. At each end of element 1 there is one clamp 3 in which two rods 4 with lock nut are secured transversely to its longitudinal axis. In the channel 5 of the broken bone 2 is located the intramedullary nail 6, which guides both parts of the bone 2 so that the axial directions are elongated.
[009] Izboljšava naprave po tem izumu je v tem, da je na kosti 2 in sicer na delu, ki je blizu sklepu, nameščen povezovalni element 7, ki vsebuje tudi dve navojni izvrtini 8, ki sta predvideni za sprejem dveh paličastih vijakov 4 s protimatico, ki sta hkrati vpeta v vsakokratni priležni sponi 3. Hkrati vsebuje povezovalni element 7 tudi skoznje izvrtine 9, ki ležijo v odmiku od navojnih izvrtin 8 in ki so predvidene za sprejem kostnih vijakov 10. Med vsakim povezovalnim elementom 7 in površino kosti 2 je nameščen prilagodni element[009] An improvement of the device according to the present invention is that a connecting element 7 is provided on the bone 2, namely at the part close to the joint, which also contains two threaded holes 8 intended for receiving two rod screws 4 s. counter-locks, which are at the same time clamped in each of the respective clamps 3. At the same time, the connecting element 7 also includes through holes 9, which are offset from the threaded holes 8 and are provided for receiving bone screws 10. Between each connecting element 7 and the surface of bone 2 is adapter element installed
II, ki zagotavlja, da leži vsak povezovalni element 7, ne glede na nepravilnoII, which ensures that each connecting element 7 lies, irregularly
Antolič-4/X-12/Vr konično obliko kosti 2, vzporedno s podaljševalnim elementom 1 oziroma pravokotno na paličasta vijaka 4.Antolich-4 / X-12 / Vr conical shape of bone 2, parallel to the extension element 1 or perpendicular to the bar screws 4.
[0010] Zaradi različnih oblik kosti 2 posameznih bolnikov, je predvideno, da so tudi prilagodni elementi 11 oblikovani različno, da se prilagajajo posameznim skupinam oblik kosti 2. V prvem izvedbenem primeru so prilagodni elementi 11 klinaste oblike z različnimi koti klina, da ustrezajo zahtevi, kot je opisana v prejšnjem odstavku. Izvrtine 12 v njem so take in na tistih mestih, da ustezajo izvrtinam 9 in potrebni usmeritvi kostnih vijakov 10. Namesto teh ali samo nekaterih izvrtin 12 so lahko izvedeni zaseki 13, ki še povečajo možnosti različnih položajev kostnih vijakov 10, kot narekuje poteba pri vsakokratni operaciji.[0010] Due to the different bone shapes of 2 individual patients, it is contemplated that the adjusting elements 11 are also designed differently to fit the individual groups of bone shapes 2. In the first embodiment, the adaptive elements 11 are wedge shaped with different wedge angles to meet the requirement as described in the previous paragraph. The holes 12 therein are such and in such places that they correspond to the holes 9 and the necessary orientation of the bone screws 10. Instead of these or only some holes 12, notches 13 may be made, which further increase the possibility of different positions of the bone screws 10, as dictated by the need for the respective surgery.
[0011] V prilagodnem elementu 11 je izveden v osni smeri potekajoč podolgovat zasek 14, ki je odprt na stanski ploskvi. Podolgovati zasek 14 je predviden za sprejem posnetega dela 15 paličastih vijakov 4. S tem je zagotovljena medsebojna pravilna lega povezovalnega elementa 7 in prilagodnega elementa 11 v vzdolžni smeri. Za boljši naleg prilagodnega elementa 11 na kost 2 je prilagodni element 11 izveden na ploskvi, ki je predvidena za nalega na kost 2, z vzdolžnim žlebom 16, ki je lahko tudi prekinjen. S privijanjem paličastih vijakov 4 skozi pripadajočo navojo izverino 8 lahko natančno izravnavamo medsebojno vzporednost obeh povezovalnih elementov.[0011] In the adaptive element 11, an elongated latch 14, which is open in the flat surface, is made in the axial direction. An elongated latch 14 is provided for receiving the recorded portion 15 of the thumb screws 4. This ensures that the longitudinal direction of the connecting element 7 and the adjusting element 11 are mutually correct. For better fit of the adjusting element 11 to the bone 2, the adjusting element 11 is made on the surface provided for the abutment on the bone 2, with a longitudinal groove 16, which may also be broken. By tightening the thumb screws 4 through the threaded hole 8, we can precisely balance the parallelism between the two connecting elements.
[0012] Intramedularni žebelj 6 je fiksiran na delu kosti blizu sklepa z vijaki 17, od katerih vsaj eden teče skozi priležni povezovalni element 7 in prilagodni element 11 in prečno skozi vso kost 2, ter skozi luknjo 18 v intramedularem žeblju 6.[0012] The intramedullary nail 6 is fixed on a portion of the bone near the joint with screws 17, at least one of which runs through the adjacent connecting element 7 and the adapter element 11 and transversely through the entire bone 2, and through the hole 18 in the intramedullary nail 6.
Antolič-4/X-12/Vr [0013] V drugem izvedbenem primeru je lahko prilagodni element 11 zasnovan kot cevast element, ki deluje kot podložka pod vsakim kostnim vijakom 10, pri čemer so na voljo različno dolgi cevasti elementi glede na posamezno potebo, kije pogojena z obliko kosti v območju vijačenja.Antolich-4 / X-12 / Vr [0013] In another embodiment, the adapter element 11 may be designed as a tubular element, which acts as a washer under each bone screw 10, with different tubular elements available depending on the individual trajectory, which is conditioned by the shape of the bone in the area of screwing.
[0014] Nadalje se izboljšava po izumu iste naprave kaže tudi v konstrukciji povezave zunanjega podaljševalnega elementa 1 z drugim delom kosti 2. Ker je kost 2 na tem delu pogosto približno cilindrične oblike, je navedena povezava zasnovana iz spone 3, ki je povezana s podaljševalnim elementom 1, nadalje iz dveh paličastih vijakov 4 s protimatico, ki ležita v sponah 3, z drugima koncema pa sta uvita v povezovalnem elementu 7 in sicer v tonamenskih navojnih izvrtinah 8. Povezovalni element 7 je fiksiran na kosti 2 s pomočjo kostnih vijakov 10, ki potekata poševno samo v kosti in nikjer ne vstopata bodisi v kanal 5 ali izven kosti 2.[0014] Further, an improvement according to the invention of the same device is also shown in the construction of the connection of the outer extension element 1 to the second part of the bone 2. Since the bone 2 in this part is often approximately cylindrical in shape, said connection is formed from a clamp 3 which is connected to the extension element 1, further from two rod bolts 4 with lock nut, which are located in the clamps 3, and the other ends are wrapped in the connecting element 7, namely, in the threaded bore holes 8. The connecting element 7 is fixed to the bone 2 by means of bone screws 10, which run obliquely only into the bone and nowhere enter either the duct 5 or the exterior 2.
[0015] Iz opisa konstrukcije povezovalnega elementa 7 in prilagodnega elementa 11 se da pojasniti njuno uporabno medicinsko novost. Na povezovalnem elementu 7 izvedeni navojni izvrtini 8 sta razporejeni v oddaljenosti od skoznih izvrtin 9, s čimer se bistveno podaljša pot morebitnim bakterijam, da bi prodrle s kožne luknje ob paličastih vijakih 4 do povezovalnega elementa 7, nadalje po njem do kostnih vijakov 10, po njihovi površini do kosti 2 in skoznjo do kanala 5. Druga prednost izboljšave po izumu pa je v tem, da prilagodni element 11 omogoča bistvemo boljšo vijačno povezavo med kostjo 2 in posredno osnovne modularne stranske naprave za podaljševanje kosti. S tem je v njen prid bistveno povečano razmerje med prednostmi in pomanjkljivostmi te naprave glede na druge istonamenske naprave, vendar drugačnih konstrukcij. Uveba prilagodnega elementa 11 zagotavlja ne glede na obliko dela kosti 2, na katerem je nameščen, tako lego povezovalnega elementa 7, da poteka vzporedno z drugim povezovalnim elementom 7 oziroma je zagotovljeno, da potekajo vsiFrom the description of the construction of the connecting element 7 and the adaptive element 11 it is possible to explain their useful medical novelty. The threaded holes 8 made on the connecting element 7 are arranged in a distance from the through holes 9, thereby significantly extending the path for any bacteria to penetrate from the skin hole along the thumb screws 4 to the connecting element 7, further downwards to the bone screws 10, Their surface to the bone 2 and through to the duct 5. Another advantage of the improvement according to the invention is that the adapter element 11 provides a substantially better screw connection between the bone 2 and the indirectly basic modular lateral bone extension device. This, in its favor, significantly increases the ratio of the advantages and disadvantages of this device to other single-purpose devices, but of different designs. The magnification of the adaptive element 11 ensures, regardless of the shape of the part of the bone 2 on which it is mounted, that the position of the connecting element 7 is parallel to the other connecting element 7, or that all
