Description
[0001] La presente invenzione è relativa al settore tecnologico delle protesi d’anca, in particolare trattasi di un collo femorale mobile con stelo per protesi come descritto nel preambolo della rivendicazione 1. [0001] The present invention relates to the technological field of hip prostheses, in particular it is a mobile femoral neck with a prosthesis stem as described in the preamble of claim 1.
[0002] Come è noto agli esperti del ramo tecnico in questione, i colli femorali mobili per protesi d’anca terminano inferiormente con una parte rastremata che viene inserita con accoppiamento in una cavità complementare ricavata nell’estremità superiore dello stelo. Detta soluzione ha rappresentato una grande evoluzione nel campo della chirurgia ortopedica sostituendo il sistema detto a monoblocco, nel quale collo e stelo formavano un elemento unico. [0002] As is known to those skilled in the art in question, the hip femoral movable necks terminate inferiorly with a tapered part which is inserted with coupling in a complementary cavity obtained in the upper end of the stem. This solution represented a great evolution in the field of orthopedic surgery by replacing the so-called monoblock system, in which the neck and stem formed a single element.
[0003] Il collo mobile consente di adattare un impianto di protesi alle diverse caratteristiche anatomiche del paziente offrendo inoltre il grande vantaggio di poter sostituire il collo, sia nel corso del primo intervento chirurgico che in occasioni successive senza dover rimuovere lo stelo dalla sua sede. [0003] The movable neck allows to adapt a prosthesis implant to the different anatomical characteristics of the patient also offering the great advantage of being able to replace the neck, both during the first surgery and on subsequent occasions without having to remove the stem from its seat.
[0004] I chirurgi ortopedici hanno però rilevato che, alcune volte, intervenendo su una protesi utilizzata per un certo lasso di tempo, il collo mobile rimane bloccato all’interno della cavità dello stelo a causa di una maggior coesione generata nel corso del suo utilizzo. Questo comporta grandi difficoltà nell’operazione di estrazione del collo dalla stelo, che non sempre si riesce a superare utilizzando estrattori di tipo convenzionale, i quali agiscono utilizzando il principio di funzionamento simile a quello di un comune cavatappi a vite. [0004] However, orthopedic surgeons have found that, sometimes, by intervening on a prosthesis used for a certain period of time, the movable neck remains locked inside the stem cavity due to a greater cohesion generated during its use . This involves great difficulty in extracting the neck from the stem, which is not always possible to overcome using conventional extractors, which act using the operating principle similar to that of a common screw corkscrew.
[0005] Scopo dell’invenzione è quindi di fornire una soluzione al summenzionato problema grazie ad un collo femorale mobile con uno stelo provvisto di caratteristiche tecniche tali da facilitarne il distacco del collo dallo stelo. [0005] The aim of the invention is therefore to provide a solution to the aforementioned problem thanks to a movable femoral neck with a stem provided with technical characteristics such as to facilitate the detachment of the neck from the stem.
[0006] L’oggetto dell’invenzione ricorre al noto principio fisico del piano inclinato, al fine di sviluppare le forze necessarie al distacco dello stelo, garantendo nel medesimo tempo, fatto molto importante al fine di evitare un incastro, anche la direzionalità di dette forze, le quali sono così in asse rispetto alla cavità dello stelo ricavata nella sua estremità superiore. [0006] The object of the invention makes use of the well-known physical principle of the inclined plane, in order to develop the forces necessary for detachment of the stem, guaranteeing at the same time, a very important fact in order to avoid a joint, also the directionality of said forces, which are thus in axis with respect to the cavity of the stem formed in its upper end.
[0007] L’invenzione prevede che il collo sia munito da due alette orientate e direzionate in modo tale da permettere ad un mezzo estrattore, come ad esempio una forchetta a due punte, un agevole distacco del collo dallo stelo. [0007] The invention provides that the neck is provided with two fins oriented and directed so as to allow an extractor means, such as a two-pronged fork, an easy detachment of the neck from the stem.
[0008] L’invenzione viene ora meglio chiarita con riferimento ai disegni allegati che illustrano schematicamente una forma preferenziale di realizzazione pratica data solo a titolo esemplificativo ma non limitativo in quanto varianti tecniche o costruttive potranno sempre essere apportate senza uscire dall’ambito della presente invenzione. [0008] The invention will now be better clarified with reference to the attached drawings which schematically illustrate a preferred embodiment given only by way of non-limiting example since technical or constructional variations may always be made without departing from the scope of the present invention .
[0009] In detti disegni: <tb>La fig. 1<sep>mostra il collo mobile 1 inserito nella cavità 4 dello stelo 2 posizionato all’interno del femore in una vista frontale che permette anche di vedere anche le due alette 5, 5a di cui il collo 2 è munito. <tb>La fig. 2<sep>mostra il collo mobile 1 in vista laterale con l’inserimento di un estrattore atto a disimpegnare detto collo 1 dallo stelo 2 grazie all’ effetto del piano inclinato, questo effetto è anche comunemente chiamato effetto cuneo.[0009] In said drawings: <tb> Fig. 1 shows the movable neck 1 inserted in the cavity 4 of the stem 2 positioned inside the femur in a front view which also allows to see also the two fins 5, 5a of which the neck 2 is provided. <tb> Fig. 2 shows the movable neck 1 in a side view with the insertion of an extractor adapted to disengage said neck 1 from the stem 2 thanks to the effect of the inclined plane, this effect is also commonly called the wedge effect.
[0010] Se si considera le fig. 1summenzionata, in esse si scorge un collo mobile 1, che presenta una parte inferiore rastremata 3, inserito in uno stelo 2 in accoppiamento forzato entro una cavità 4, sostanzialmente complementare alla parte rastremata 3 di detto collo 1, ricavata nello stelo 2. [0010] If we consider fig. 1 mentioned, a movable neck 1 can be seen therein, which has a tapered lower part 3, inserted in a stem 2 in forced coupling within a cavity 4, substantially complementary to the tapered part 3 of said neck 1, formed in the stem 2.
[0011] Sul corpo del collo mobile 2, nella parte non rastremata 3, sono ricavate due alette 5 e 5a che sono orientate sostanzialmente in modo perpendicolare all’asse della cavità in cui il collo è inserito, inoltre dette alette 5 e 5a hanno una forma e posizione tale che inserendo un mezzo estrattore E, a forma di forchetta munita di due punte aventi delle pareti convergenti verso dette alette 5 e 5a. [0011] On the body of the movable neck 2, in the non-tapered part 3, there are two tabs 5 and 5a which are oriented substantially perpendicularly to the axis of the cavity in which the neck is inserted, moreover said tabs 5 and 5a have a shape and position such that by inserting a fork-shaped extractor means E having two points having walls converging towards said wings 5 and 5a.
[0012] Dette pareti, in fase di estrazione collo, appoggiano contro la superficie delle alette 5 e 5a e la superficie facente parte dello stelo 2 esercitando per l’effetto fisico del piano inclinato una spinta F di direzione parallela all’asse della cavità, come illustrato nella fig. 2atta a provocare l’estrazione del collo mobile dallo stelo. [0012] Said walls, in the neck extraction phase, rest against the surface of the fins 5 and 5a and the surface forming part of the stem 2 exerting for the physical effect of the inclined plane a thrust F of direction parallel to the axis of the cavity, as shown in fig. Suitable to cause the extraction of the mobile neck from the stem.
[0013] Nella forma preferenziale di esecuzione le alette sono ricavate longitudinalmente sul corpo di detto collo 1 e ad distanza h tale dallo stelo in modo da permettere l’entrata delle punte dell’estrattore E, in una seconda forma di esecuzione dette alette sono ricavate trasversalmente sul corpo del collo mobile 1. [0013] In the preferred embodiment, the fins are formed longitudinally on the body of said neck 1 and at a distance h from the stem so as to allow the tips of the extractor E to enter, in a second embodiment said fins are formed transversely on the body of the movable neck 1.
[0014] I vantaggi dell’invenzione rispetto alle soluzioni conosciute sono: una semplice estrazione del collo e una minore forza da applicare per l’estrazione del collo grazie all’effetto del piano inclinato. [0014] The advantages of the invention with respect to the known solutions are: a simple extraction of the neck and a lower force to be applied for the extraction of the neck thanks to the effect of the inclined plane.
