Description
Brevetto di Invenzione industriale Industrial Invention Patent
Terza versione della doppia pinza per laparoscopia mono accesso. Third version of the double forceps for single access laparoscopy.
Stato dell’Arte. State of the art.
Lo stato dell’arte della SAL (Single Access Laparoscopy) è stato già ampiamente illustrato nelle domande di brevetto CS2012A000006 del 22/02/2012 e CS2012A000032 del 07/09/2012 e perciò non viene qui ripetuto. The state of the art of SAL (Single Access Laparoscopy) has already been extensively illustrated in patent applications CS2012A000006 of 02/22/2012 and CS2012A000032 of 09/07/2012 and therefore is not repeated here.
Scopo della nuova domanda di brevetto è la puntualizzazione del fatto che non necessariamente il piano di apertura dei bracci deve essere coincidente con quello di movimentazione degli anelli di comando, basta a tale scopo ad esempio fare uso del sistema di trasmissione a cavi e pulegge per trasmettere il moto dalla zona di comando a quella di attuazione, cosa già specificata nel primo brevetto presentato. Anzi tale configurazione potrebbe essere preferibile in talune circostanze, senza contare il fatto che ciò potrebbe facilitare il fatto di inclinare lateralmente gli anelli, in modo che il loro comando possa lasciar libero un maggior spazio di lavoro per l’ottica e lo strumento chirurgico. The purpose of the new patent application is the clarification of the fact that the opening plane of the arms does not necessarily have to coincide with that of the movement of the control rings, it is sufficient for this purpose, for example, to make use of the cable and pulley transmission system to transmit motion from the control area to the actuation area, which is already specified in the first patent presented. Indeed, this configuration may be preferable in certain circumstances, not to mention the fact that this could facilitate the fact of tilting the rings laterally, so that their command can leave more space for the optics and the surgical instrument to work.
Descrizione della realizzazione preferita. Description of the preferred embodiment.
Prima di illustrare la nuova pinza che apre i bracci in direzione diversa da quella di azionamento degli anelli, osserviamo in Tavola 1 un meccanismo semplificato che realizza comunque i movimenti previsti dai due precedenti brevetti sopra citati, sopprimendo tutte le ruote dentate interne eccettuate quelle che accoppiano il moto opposto dei bracci e dei braccetti, adottando una sorta di trasmissione a pulegge. In particolare ai lati del tamburo collegato all’anello di comando (1) sono poste due pulegge di diametro doppio di quelle poste all’altra estremità della base interna (2), in modo da realizzare appunto la moltiplica del movimento. Inoltre, mentre la puleggia posta su un lato comanda la puleggia che aziona l’apertura di un braccio (3), collegato tramite dentatura al contro braccio, l’altra comanda una diversa puleggia (4), anch’essa dotata di dentatura e di una seconda puleggia coassiale, in modo da trasmettere le contro rotazioni ai braccetti reggi forcipe (5), sempre attraverso una coppia di pulegge, che trasmettono il moto in tutti e due i bracci. Before illustrating the new gripper that opens the arms in a different direction from that of the rings, we observe in Table 1 a simplified mechanism which in any case carries out the movements envisaged by the two previous patents cited above, eliminating all the internal toothed wheels except those that couple the opposite motion of the arms and arms, adopting a sort of pulley transmission. In particular, on the sides of the drum connected to the control ring (1) there are two pulleys with a double diameter of those placed at the other end of the internal base (2), in order to precisely multiply the movement. Furthermore, while the pulley placed on one side controls the pulley which activates the opening of an arm (3), connected by toothing to the counter arm, the other controls a different pulley (4), also equipped with toothing and a second coaxial pulley, so as to transmit the counter rotations to the forceps holder arms (5), again through a pair of pulleys, which transmit the motion in both arms.
Per meglio comprendere come siano fatte le pulegge, che data la delicatezza delle applicazioni non possono consentire scorrimenti indesiderati, osserviamo in Tavola 2, come possono essere costruite queste pulegge anti scorrimento. In particolare la figura mostra il percorso seguito dal cavo, che viene bloccato tra la base ed un coperchio, costringendolo ad una serie di curvature ad angolo retto, che ne impediscono lo scorrimento. Passando a Tavola 3, notiamo che la base interna (6), anziché essere piatto, presenta una torsione di 90° tra la zona di imperniatura degli anelli (7) e quella delle basi dei bracci reggi forcipe (8), permettendo appunto l’apertura su un piano diverso da quello di azionamento. To better understand how the pulleys are made, which given the delicacy of the applications cannot allow unwanted sliding, let's see in Table 2, how these anti-sliding pulleys can be built. In particular, the figure shows the path followed by the cable, which is blocked between the base and a lid, forcing it to a series of right-angled bends, which prevent it from sliding. Moving on to Table 3, we note that the internal base (6), instead of being flat, has a 90 ° twist between the pivoting area of the rings (7) and that of the bases of the forceps holder arms (8), allowing precisely the opening on a plane other than that of actuation.
Si badi, ancora una volta, come la meccanica interna possa essere variata a piacere, ciò che conta è che vi sia un’unica pinza che è in grado di aprirsi portando all’estremità due strumenti diversi, che nell’opinione degli autori di questo brevetto dovrebbero essere unicamente forcipi di presa, ma che potrebbero anche essere dissettori, portaghi, forbici, etc. La ragione per cui si sconsiglia tale soluzione, è che, mentre afferrare un elemento corporeo da due parti e tenerlo fermo o spostarlo in modo da facilitare il lavoro con un secondo strumento indipendente dai due bracci, ha molto senso, non sembra altrettanto logico muovere un’estremità dello strumento tenendo ferma l’altra. E comunque tale realizzazione non presenterebbe un elemento di innovazione, essendo già prevista in questa sede. Remember, once again, how the internal mechanics can be varied at will, what matters is that there is a single gripper that is able to open bringing two different instruments to the end, which in the opinion of the authors of this patent should only be grasping forceps, but which could also be dissectors, needle holders, scissors, etc. The reason why this solution is not recommended is that, while grasping a body element from two sides and holding it still or moving it in order to facilitate work with a second instrument independent of the two arms, it makes a lot of sense, it does not seem so logical to move a end of the instrument while holding the other. And in any case, this realization would not present an element of innovation, as it is already foreseen here.
