Title
(DE) CHIRURGISCHES RESEKTIONSGERÄT
(EN) SURGICAL RESECTION DEVICE
(FR) DISPOSITIF DE RESECTION CHIRURGICALE
Abstract
(EN)
A surgical organ resection device comprising a plurality of elongate electrodes (4) for insertion into organ tissue, the electrodes being capable of operating in a bipolar manner, and an input for receiving a drive signal for driving the electrode, the elongate electrodes being arranged in a two-dimensional array and/or the device being arranged such that, in use, subsets of the elongate electrodes are driven in turn.

(FR)
L'invention concerne un dispositif de résection d'organe chirurgicale. Ce dispositif comprend une pluralité d'électrodes allongées (4) pour une insertion dans un tissu organique. Ces électrodes peuvent fonctionner de manière bipolaire. Le dispositif comprend une entrée pour recevoir un signal pilote pour piloter l'électrode. Des électrodes allongées sont agencées dans une configuration bidimensionnelle et/ou le dispositif est agencé de sorte que, lors de son utilisation, des sous-ensembles d'électrodes allongées sont pilotés tour à tour.
