Title (EN) ELECTROSURGICAL APPARATUS FOR TISSUE ABLATION
(FR) APPAREIL ÉLECTROCHIRURGICAL POUR ABLATION DE TISSU
Abstract:
(EN) An electrosurgical apparatus for treating fluid-filled biological growths by replacing the fluid within the growth with a substance that assists in delivering treatment energy. The treatment energy may be microwave energy or may be thermal energy derived from microwave energy. The apparatus comprises an instrument having a radiating tip portion, and a fluid delivery mechanism for transporting fluid to and from a treatment zone located around the radiating tip portion. The fluid delivery mechanism comprises a rigid insertion element arranged to extend into the treatment zone, whereby fluid can be aspirated from the treatment zone, and a substance injected into the treatment zone to replace the aspirated fluid. The injected substance has dielectric properties selected to facilitate uniform delivery of treatment energy to biological tissue in the treatment zone.
(FR) La présente invention concerne un appareil électrochirurgical pour traiter des excroissances biologiques remplies de fluide par le remplacement du fluide à l'intérieur de l’excroissance par une substance qui facilite l'administration d'énergie de traitement. L'énergie de traitement peut être de l'énergie micro-onde ou peut être de l'énergie thermique dérivée de l'énergie micro-onde. L'appareil comprend un instrument ayant une partie de pointe rayonnante, et un mécanisme de distribution de fluide pour transporter un fluide vers et depuis une zone de traitement située autour de la partie de pointe rayonnante. Le mécanisme de distribution de fluide comprend un élément d'insertion rigide conçu pour s'étendre dans la zone de traitement, grâce auquel un fluide peut être aspiré depuis la zone de traitement, et une substance injectée dans la zone de traitement pour remplacer le fluide aspiré. La substance injectée a des propriétés diélectriques sélectionnées pour faciliter l'administration uniforme d'énergie de traitement à un tissu biologique dans la zone de traitement.
