Description
“SPAZIATORE PER MEMBRANE IN OPERAZIONI DI CHIRURGIA OSSEA.†⠀ œSPACER FOR MEMBRANES IN BONE SURGERY OPERATIONS.â €
La presente invenzione concerne uno spaziatore per membrane in operazioni di chirurgia ossea. The present invention relates to a spacer for membranes in bone surgery operations.
Nel campo della chirurgia orale, il ripristino della corretta anatomia mandibolare o mascellare richiede alcune verifiche preliminari legate alla situazione clinica di ogni singolo paziente. In the field of oral surgery, the restoration of the correct mandibular or maxillary anatomy requires some preliminary checks linked to the clinical situation of each individual patient.
Una delle criticità riscontrate più frequentemente si concretizza in un’insufficienza di osso a disposizione del medico, su cui agire per inserire gli impianti necessari a supportare le protesi dentarie. One of the most frequently encountered criticalities is the lack of bone available to the doctor, on which to act to insert the implants necessary to support dental prostheses.
Una delle più recenti tecniche di rigenerazione ossea intraorale prevede la creazione di un “contenitore†idoneo ad essere riempito con materiale da innesto destinato a ricostituire la quantità di osso mancante; tale materiale à ̈ generalmente identificato come “osso granulare†. Per fare ciò, à ̈ necessario fissare all’osso già presente (“osso basale†), nella zona di intervento, due membrane, posizionate in modo sostanzialmente parallelo fra loro, che assumono la funzione di pareti del contenitore e che sono realizzate in un materiale adatto ad essere integrato ed assorbito dall’organismo come l’acido polilattico (PDLLA). One of the most recent intraoral bone regeneration techniques involves the creation of a â € œcontainerâ € suitable to be filled with graft material intended to replenish the amount of missing bone; this material is generally identified as "granular bone". To do this, it is necessary to fix to the bone already present (â € œbasal boneâ €), in the intervention area, two membranes, positioned substantially parallel to each other, which take on the function of container walls and which are made in a material suitable to be integrated and absorbed by the body such as polylactic acid (PDLLA).
Tale posizionamento fino ad oggi à ̈ stato eseguito a mano; pertanto, à ̈ facile intuire che, mentre il fissaggio della prima membrana (“vestibolare†, e dunque esterna) non presenta particolari difficoltà , il corretto posizionamento della seconda membrana (“linguale†e quindi interna) à ̈ ostacolato dal poco spazio a disposizione, dalla limitata visibilità e, soprattutto, dall’avere una sola mano libera per il fissaggio, mentre l’altra à ̈ impegnata a mantenere in posizione la membrana stessa. Up to now this positioning has been done by hand; therefore, it is easy to understand that, while the fixing of the first membrane (â € œbestibularâ €, and therefore external) does not present particular difficulties, the correct positioning of the second membrane (â € œlingualâ € and therefore internal) is hindered by the limited space available, from limited visibility and, above all, from having only one free hand for fixing, while the other is committed to keeping the membrane in position.
Scopo del presente trovato à ̈ pertanto quello di eliminare gli inconvenienti sopra menzionati. The aim of the present invention is therefore to eliminate the aforementioned drawbacks.
Il trovato, quale esso à ̈ caratterizzato dalle rivendicazioni, raggiunge lo scopo mediante la possibilità di tenere in posizione di fissaggio le membrane senza un intervento diretto del medico. The invention, as it is characterized by the claims, achieves the object by being able to hold the membranes in the fixing position without direct intervention by the doctor.
Il principale vantaggio ottenuto mediante il presente trovato consiste nel fatto che si ottiene un posizionamento ottimale di entrambe le membrane; inoltre si hanno le mani libere ed una maggiore visibilità in qualsiasi fase operativa, in particolare al momento del fissaggio della seconda membrana. In tal modo, si ha una riduzione dei tempi dell’intervento, con un indubbio beneficio per il paziente, ed una semplificazione tecnica per il medico. The main advantage obtained by means of the present invention consists in the fact that an optimal positioning of both membranes is obtained; moreover, you have hands free and greater visibility in any operational phase, in particular when the second membrane is fixed. In this way, there is a reduction in the time of intervention, with an undoubted benefit for the patient, and a technical simplification for the doctor.
Infine, il trovato può essere adattabile alle esigenze di numerosi pazienti. Ulteriori vantaggi e caratteristiche del trovato saranno maggiormente evidenti nella descrizione dettagliata che segue, fatta con riferimento ai disegni allegati, che ne rappresentano un esempio non limitativo di esecuzione, in cui: Finally, the invention can be adapted to the needs of numerous patients. Further advantages and characteristics of the invention will be more evident in the detailed description that follows, made with reference to the attached drawings, which represent a non-limiting example of execution, in which:
- la figura 1 illustra il trovato secondo una vista prospettica dall’alto; Figure 1 illustrates the invention according to a perspective view from above;
-la figura 2 illustra il trovato secondo una vista dall’alto in una condizione d’uso con un particolare ingrandito. Figure 2 illustrates the invention according to a top view in a condition of use with an enlarged detail.
Come si può osservare dalle figure, il presente trovato concerne uno spaziatore per membrane in operazioni di chirurgia ossea: esso comprende un’impugnatura (1) ed almeno due organi di presa (2), atti al serraggio ed al rilascio delle membrane (3). As can be seen from the figures, the present invention relates to a spacer for membranes in bone surgery operations: it comprises a handle (1) and at least two gripping members (2), suitable for tightening and releasing the membranes (3 ).
Per evitare di realizzare una vasta gamma dimensionale di spaziatori (10), ognuno utilizzabile per ogni singolo paziente, e per rispondere comunque alle esigenze di un elevato numero di pazienti, i quali avranno ovviamente arcate dentali di diverse dimensioni, Ã ̈ opportuno che lo spaziatore (10) comprenda mezzi di regolazione (4) della posizione relativa degli organi di presa (2). To avoid creating a wide dimensional range of spacers (10), each usable for each individual patient, and in any case to meet the needs of a large number of patients, who obviously will have dental arches of different sizes, it is advisable that the spacer (10) comprises means for adjusting (4) the relative position of the gripping members (2).
Tali mezzi di regolazione (4) comprendono guide (41) di scorrimento, atte a modificare la distanza tra gli organi di presa (2). Said adjustment means (4) comprise sliding guides (41), adapted to modify the distance between the gripping members (2).
Inoltre, anche se le membrane (3) vanno generalmente posizionate parallele tra loro, in certi casi potrebbe essere vantaggioso che i mezzi di regolazione (4) comprendessero perni (42) di rotazione, atti a modificare l’angolazione tra gli organi di presa (2). Furthermore, even if the membranes (3) must generally be positioned parallel to each other, in certain cases it could be advantageous for the adjustment means (4) to include rotation pins (42), suitable for modifying the angle between the gripping members (2).
Il trovato così concepito à ̈ suscettibile di numerose modifiche e varianti, tutte rientranti nell’ambito del concetto inventivo. Inoltre, tutti i dettagli possono essere sostituiti da elementi tecnicamente equivalenti. The invention thus conceived is susceptible of numerous modifications and variations, all of which are within the scope of the inventive concept. Furthermore, all the details can be replaced by technically equivalent elements.
Nella pratica sono ovviamente possibili delle modifiche e/o delle migliorie rientranti comunque nell’ambito delle seguenti rivendicazioni. In practice, modifications and / or improvements are obviously possible, in any case falling within the scope of the following claims.
