The blades have electrodes capable of delivery RF and/or microwave energy to cut or coagulate tissue between them. The tool combines the actuation and energy delivery mechanisms in a compact arrangement that enables the tool to be inserted through an instrument channel of a surgical scoping device, such as an endoscope, gastroscope or laparoscope. Each blade may comprises a planar body made of dielectric material that separates a first conductive element from a second conductive element. The blades may rotate relative to each other in the plane of the blades. 40 1-1 IN FIG. 1 1-1 0 ei o [Continued on next page] WO 2017/198671 Al MIDEDIMOMOIDEIROIDEMOMOHHEIIMMHIMEMOIMIE EE, ES, FI, FR, GB, GR, HR, HU, IE, IS, IT, LT, LU, LV, MC, MK, MT, NL, NO, PL, PT, RO, RS, SE, SI, SK, SM, TR), OAPI (BF, BJ, CF, CG, CI, CM, GA, GN, GQ, GW, KM, ML, MR, NE, SN, TD, TG).
