An endoscope comprises a telescope (12), an electrode assembly (13) comprising at least one electrode (13T), and elongate conductive means (13S) for supplying electrosurgical power to said at least electrode from the proximal end of the conductive means. Means are provided for supporting the electrode assembly (13) on the telescope (12) for pivotal movement, in a plane substantially normal to the axis of the telescope, towards, and away from, an operational position in which the conductive means (13S) is substantially parallel to the telescope. Sealing means (16,29) seals the electrode assembly (13) to prevent fluid passing from an operation site adjacent to said at least one electrode (13T) to the proximal end of the conductive means (13S). |
