D E S C RI Z I ON E DESCRIPTION
del BREVETTO per INVENZIONE INDUSTRIALE avente per titolo: of the PATENT for INDUSTRIAL INVENTION entitled:
“CATETERE PER L’ABLAZIONE DI ZONE RESECATE” "CATHETER FOR THE ABLATION OF RESTORED AREAS"
La presente invenzione riguarda in generale il settore dei cateteri per l’impiego in chirurgia e si riferisce in particolare ad un catetere a radiofrequenza per l’ablazione di zone resecate. The present invention generally relates to the sector of catheters for use in surgery and refers in particular to a radiofrequency catheter for the ablation of resected areas.
Gli interventi di resezione di zone malate richiedono' particolari e accurati trattamenti di ablazione, per asportare quanto necessario e idonei a favorire la cicatrizzazione della ferita. Resection of diseased areas requires special and accurate ablation treatments, to remove what is necessary and suitable for promoting wound healing.
Uno scopo dell’invenzione è di proporre e fornire un catetere nuovo e originale concepito specificatamente per un trattamento a radiofrequenza di zone resecate. One purpose of the invention is to propose and supply a new and original catheter specifically designed for radiofrequency treatment of resected areas.
Un altro scopo dell’invenzione è di realizzare un catetere con una particolare testa di ablazione e di trattamento delle zone resecate e che possa anche essere attraversato da un filo di sonda per la misurazione della temperatura a livello delle parti trattate. Another purpose of the invention is to make a catheter with a particular head for ablation and treatment of the resected areas and which can also be crossed by a probe wire for measuring the temperature at the level of the treated parts.
Detti scopi sono raggiunti in accordo con l invenzione a mezzo di un catetere per l’ablazione di zone resecate che comprende un elemento tubolare conduttore di radiofrequenza, racchiuso in una guaina isolante ed avente un’estremità prossimale e un’estremità distale, un connettore connesso al’estremità prossimale dell’elemento tubolare e collegabile ad un generatore di radiofrequenza e una testa di trattamento fissata al'estremità distale di detto elemento tubolare. Said purposes are achieved in accordance with the invention by means of a catheter for the ablation of resected areas which comprises a radiofrequency conducting tubular element, enclosed in an insulating sheath and having a proximal end and a distal end, a connector connected at the proximal end of the tubular element and connectable to a radiofrequency generator and a treatment head fixed to the distal end of said tubular element.
Aggiuntivamente, il catetere comprende un filo di sonda passante longitudinalmente nell’elemento tubolare e connesso a un termistore per misurazione della temperatura presso la testa di trattamento. Additionally, the catheter includes a probe wire passing longitudinally in the tubular element and connected to a thermistor for measuring the temperature at the treatment head.
Il catetere secondo il trovato sarà peraltro qui di seguito descritto più in dettaglio facendo riferimento agli allegati disegni, indicativi e non limitativi, nei quali: The catheter according to the invention will however be described in more detail below with reference to the accompanying drawings, indicative and not limiting, in which:
la Fig. 1 mostra un insieme di catetere per ablazione; Fig. 1 shows an ablation catheter assembly;
la Fig. 2 mostra una sezione trasversale ingrandita secondo le frecce A - A sulla Fig. 1 ; Fig. 2 shows an enlarged cross section according to the arrows A - A on Fig. 1;
la Fig. 3 mostra una sezione parziale, ingrandita, dell’ estremità prossimale del catetere cerchiata e indicata con P sulla Fig.l; Fig. 3 shows an enlarged partial section of the proximal end of the catheter circled and indicated with P on Fig.
la Fig. 4 mostra una sezione parziale ingrandita deH’estremità distale con testa di trattamento cerchiata e indicata con D nella Fig. Fig. 4 shows an enlarged partial section of the distal end with the treatment head circled and indicated with D in Fig.
la Fig. 5 mostra il catetere della Fig. 1 con associata una termocoppia per la misurazione della temperatura. Fig. 5 shows the catheter of Fig. 1 with an associated thermocouple for measuring the temperature.
Come rappresentato, il catetere qui proposto comprende essenzialmente un elemento tubolare (11) e una testa di trattamento (12). L’elemento tubolare (11) è in un materiale conduttore di radiofrequenza, è racchiuso in una guaina isolante esterna (13) e ha un foro longitudinale (14). Esso si presenta con un’estremità prossimale P che è inserita in una parte di impugnatura (14|) è che è collegata, in (15), ad un cavo (16) che fa capo ad un connettore (17) collegabile ad un generatore di radiofrequenza, e con un’estremità distale D alla quale è fissata la testa di trattamento (12). As shown, the catheter proposed here essentially comprises a tubular element (11) and a treatment head (12). The tubular element (11) is made of a radiofrequency conductor material, is enclosed in an external insulating sheath (13) and has a longitudinal hole (14). It has a proximal end P which is inserted in a handle part (14 |) and which is connected, in (15), to a cable (16) which leads to a connector (17) which can be connected to a generator of radiofrequency, and with a distal end D to which the treatment head is fixed (12).
Questa testa (12) è sostanzialmente a forma di fungo e può essere scelta con dimensioni appropriate, compatibilmente con il trattamento da effettuare. This head (12) is substantially mushroom-shaped and can be chosen with appropriate dimensions, compatibly with the treatment to be carried out.
Essa presenta una superficie frontale funzionale (18) che è bombata e, sul retro, una superficie dorsale e un gambo recanti un rivestimento (19) formato da una vernice isolante in continuazione con la guaina isolante (13) che ricopre l’elemento tubolare (1 1). It has a functional front surface (18) which is rounded and, on the back, a dorsal surface and a stem bearing a coating (19) formed by an insulating paint in continuation with the insulating sheath (13) covering the tubular element ( 1 1).
Quando collegato al generatore di radiofrequenza, il catetere sopra descritto è utilizzabile efficientemente con la sua testa (12) in particolare per l’ablazione e in generale il trattamento di zone resecate. When connected to the radiofrequency generator, the catheter described above can be used efficiently with its head (12) in particular for ablation and in general for the treatment of resected areas.
Inoltre nel foro longitudinale (14) dell’elemento tubolare (11) può essere infilato, dall’estremità prossimale fino a uscire dall’estremità distale - v. Fig. 5 - un filo di termocoppia (20) per rilevare e poter misurare la temperatura a livello della testa di trattamento ovvero nell’ambito della zona resecata e trattata con il catetere. Furthermore, in the longitudinal hole (14) of the tubular element (11) it can be inserted, from the proximal end up to exit from the distal end - v. Fig. 5 - a thermocouple wire (20) to detect and be able to measure the temperature at the level of the treatment head or in the area resected and treated with the catheter.
