Description
“Dispositivo elettrochirurgico per perforazioni ovariche” "Electrosurgical device for ovarian perforations"
TESTO DELLA DESCRIZIONE TEXT OF THE DESCRIPTION
Campo dell’invenzione Field of the invention
La presente invenzione si riferisce in generale al campo della medicina riproduttiva con particolare riferimento alla fecondazione artificiale. The present invention refers in general to the field of reproductive medicine with particular reference to artificial fertilization.
Alcune donne in età fertile e desiderose di prole sono affette da mancanza cronica di ovulazione dovuta ad una patologia ovarica denominata “ovaio policistico” (PCO). Tale patologia comporta spesso la totale assenza del ciclo mestruale. Nei casi di PCO si osserva un volume ovario aumentato e la presenza di una capsula ovarica biancastra, ispessita e resistente. Some women of childbearing age and desirous of offspring suffer from chronic lack of ovulation due to an ovarian disease called “polycystic ovary” (PCO). This pathology often involves the total absence of the menstrual cycle. In cases of PCO there is an increased ovary volume and the presence of a whitish, thickened and resistant ovarian capsule.
La terapia della PCO è rappresentata da farmaci induttori dell’ovulazione, che tuttavia risultano efficaci soltanto in una parte dei soggetti. Alcune pazienti infatti, non rispondono ai farmaci e si mantengono anovulari nonostante la terapia. PCO therapy is represented by ovulation-inducing drugs, which, however, are effective only in a part of the subjects. In fact, some patients do not respond to drugs and remain anovular despite therapy.
Stato della tecnica anteriore State of the prior art
La letteratura medica dimostra che è possibile migliorare la risposta ai farmaci, e talvolta ripristinare l’ovulazione anche senza somministrare farmaci, se si praticano dei fori nella capsula delle ovaie policistiche. Tale procedura è denominata a livello internazionale “ovarian drilling” e prevede l’impiego di un dispositivo coagulatore dotato di una punta in grado di condurre elettricità e di bucare la capsula ovarica per contatto diretto. The medical literature shows that it is possible to improve the response to drugs, and sometimes restore ovulation even without administering drugs, if holes are made in the capsule of the polycystic ovaries. This procedure is internationally known as "ovarian drilling" and involves the use of a coagulator device equipped with a tip capable of conducting electricity and piercing the ovarian capsule by direct contact.
Il coagulatore, monopolare o bipolare, viene utilizzato nel corso di un intervento chirurgico endoscopico detto “laparoscopia”, che si effettua in regime di ricovero ospedaliero ed in anestesia generale, della durate di circa 40 minuti. Durante la laparoscopia si procede inserendo attraverso la parete addominale un dispositivo a fibre ottiche per visualizzare i visceri su uno schermo e due altri tubicini cavi entro i quali è possibile far passare i ferri chirurgici per effettuare l’intervento. Entro uno di essi viene introdotto il coagulatore che viene portato a contatto dalla capsula ovarica per effettuare il “drilling” elettrochirurgico. The monopolar or bipolar coagulator is used during an endoscopic surgery called “laparoscopy”, which is carried out in hospital and under general anesthesia, lasting about 40 minutes. During laparoscopy, a fiber optic device is inserted through the abdominal wall to view the viscera on a screen and two other hollow tubes within which it is possible to pass the surgical instruments to perform the surgery. The coagulator is introduced into one of them and is brought into contact by the ovarian capsule to perform electrosurgical drilling.
Nel corso delle procedure di fecondazione in vitro per le coppie infertili è prassi corrente prelevare gli ovociti dalle ovaie mediante puntura ovarica ecoguidata per via transvaginale. Tale intervento richiede pochi minuti, si effettua in regime ambulatoriale (senza ricovero) ed in anestesia locale. In the course of in vitro fertilization procedures for infertile couples, it is common practice to collect oocytes from the ovaries by transvaginal ultrasound-guided ovarian puncture. This operation takes a few minutes, is carried out on an outpatient basis (without hospitalization) and under local anesthesia.
Sulla sonda ecografia transvaginale si monta una guida (monouso o sterilizzabile) per ago, all’interno della quale viene fatto passare un ago dotato di punta ecoriflettente e collegato con una pompa di aspirazione. Pungendo ripetutamente l’ovaio si aspirano gli ovociti controllando il proprio operato sullo schermo dell’ecografo. Su quest’ultimo compare una linea tratteggiata (guida) che funge da “puntatore” per orientare l’angolo della puntura in modo da pungere le ovaie nel punto più idoneo. A needle guide (disposable or sterilizable) is mounted on the transvaginal ultrasound probe, inside which a needle with an ecoreflective tip is passed and connected to a suction pump. By repeatedly pricking the ovary, the oocytes are aspirated, checking their actions on the ultrasound screen. A dotted line (guide) appears on the latter which acts as a "pointer" to orient the angle of the puncture so as to puncture the ovaries in the most suitable point.
Sommario dell’invenzione Summary of the invention
Lo scopo della presente invenzione è quello di predisporre un dispositivo elettrochirurgico per “ovarian drilling” esente dagli inconvenienti dei coagulatori per laparoscopia convenzionali di cui si è detto, e che consenta invece di utilizzare la stessa tecnica della puntura ovarica per via transvaginale. The object of the present invention is to provide an electrosurgical device for "ovarian drilling" which is free from the drawbacks of conventional coagulators for laparoscopy mentioned above, and which instead allows the use of the same technique of ovarian puncture via the transvaginal route.
Secondo l’invenzione, questo scopo viene conseguito tramite un dispositivo elettrochirurgico per perforazioni ovariche caratterizzato dal fatto di consistere in un ago coagulatore dotato di una punta di perforazione elettricamente conduttiva ed ecoriflettente collegabile ad una sorgente di alimentazione elettrica, l’ago essendo inseribile entro una guida per ago applicata ad una sonda ecografica transvaginale. According to the invention, this object is achieved by means of an electrosurgical device for ovarian perforations characterized in that it consists of a coagulating needle equipped with an electrically conductive and echo-reflective perforation tip which can be connected to an electrical power source, the needle being inserted into a needle guide applied to a transvaginal ultrasound probe.
Descrizione dettagliata dell’invenzione Detailed description of the invention
In una forma preferita di attuazione il dispositivo elettrochirurgico per “ovarian drilling” transvaginale ecoguidato consiste in un ago metallico sostanzialmente analogo agli aghi già disponibili in commercio per prelievo ovocitario. In a preferred embodiment, the ultrasound-guided transvaginal electrosurgical device for ovarian drilling consists of a metal needle substantially similar to the needles already commercially available for oocyte retrieval.
Tale ago è tipicamente lungo circa 35 cm, presenta un diametro di 16-17 gauges. Esso è dotato ad un’estremità di un’impugnatura di plastica ed all’estremità opposta di una punta smussata a becco di flauto, formata con zigrinature esterne che la rendono ecoriflettente e ben visibile ad un’ecografia transvaginale. This needle is typically about 35 cm long, has a diameter of 16-17 gauges. It is equipped at one end with a plastic handle and at the opposite end with a blunt flute-beak tip, formed with external knurls that make it echo-reflective and clearly visible to a transvaginal ultrasound.
La punta è elettricamente conduttrice per circa 3-5 mm, mentre la restante parte del corpo dell’ago è schermata da una camicia isolante. The tip is electrically conductive for about 3-5 mm, while the remaining part of the needle body is shielded by an insulating jacket.
L’ago è cavo ed è attraversato da conduttori atti a collegare la punta con una sorgente di alimentazione elettrica in modo analogo agli aghi correntemente impiegati per elettrochirurgia e per drilling laparoscopico. The needle is hollow and is crossed by conductors designed to connect the tip with an electrical power source in a similar way to the needles currently used for electrosurgery and for laparoscopic drilling.
Le dimensioni e la forma dell’ago sono come detto analoghe a quelle degli aghi per prelievo ovocitario: in tal modo esso può essere inserito entro una guida per ago, monouso o sterilizzabile, del tipo normalmente applicato alle sonde ecografiche transvaginali. The size and shape of the needle are, as mentioned, similar to those of the needles for egg retrieval: in this way it can be inserted into a needle guide, disposable or sterilizable, of the type normally applied to transvaginal ultrasound probes.
Nell’uso, l’ago inserito attraverso la guida della sonda ecografia viene introdotto in modo ecoguidato per via transvaginale, con semplice anestesia locale. Controllando l’operato sullo schermo dell’ecografo, il chirurgo orienta l’ago facendolo penetrare nella capsula ovarica per l’effettuazione delle perforazioni. La schermatura del corpo dell’ago impedisce che la corrente elettrica possa danneggiare strutture anatomiche limitrofe alle ovaie, quali ad esempio anse intestinali. La punta ecoriflettente non schermata dell’ago consente di elettrocoagulare la superficie dell’ovaio nei punti di perforazione, producendo un effetto emostatico sul tessuto ed impedendo il verificarsi di sanguinamenti indesiderati. In use, the needle inserted through the guide of the ultrasound probe is introduced in an ultrasound-guided way transvaginally, with simple local anesthesia. By checking the operation on the ultrasound screen, the surgeon orients the needle by making it penetrate into the ovarian capsule to perform the perforations. The shielding of the needle body prevents the electric current from damaging anatomical structures adjacent to the ovaries, such as intestinal loops. The unshielded ecoreflective tip of the needle allows the surface of the ovary to be electrocoagulated at the points of perforation, producing a hemostatic effect on the tissue and preventing the occurrence of unwanted bleeding.
Rispetto al drilling ovarico laparoscopico il dispositivo secondo l’invenzione permette di conseguire i seguenti vantaggi: Compared to laparoscopic ovarian drilling, the device according to the invention allows the following advantages to be achieved:
- nessuna necessità di ricovero per la paziente, - no need for hospitalization for the patient,
- significativa riduzione del rischio anestesiologico, grazie alla possibilità di sottoporre la paziente a semplice anestesia locale e non generale, - significant reduction of the anesthetic risk, thanks to the possibility of subjecting the patient to simple local and not general anesthesia,
- significativa riduzione del rischio chirurgico, grazie al fatto che l’intervento è sensibilmente meno invasivo e più veloce, - significant reduction in surgical risk, thanks to the fact that the surgery is significantly less invasive and faster,
- maggiore accettabilità per le pazienti, - greater acceptability for patients,
- maggiore ripetibilità della procedura, - greater repeatability of the procedure,
- risparmio di risorse per l’ospedale e per la collettività. - saving of resources for the hospital and the community.
Naturalmente, le forme di attuazione del dispositivo potranno essere ampiamente variate rispetto a quanto sopradescritto, senza per questo uscire dall’ambito della presente invenzione così come definita nelle rivendicazioni che seguono. Of course, the embodiments of the device can be widely varied with respect to what is described above, without thereby departing from the scope of the present invention as defined in the following claims.
