摘要:
An electrosurgical instrument for applying to biological tissue RFelectromagnetic energyand/or microwave frequency EM energy, wherein the instrument tip has aprotective hull with asmoothly contoured convex undersurface facing away from a planar body, andwherein theplanar body has a tapering distal edge, and wherein an underside of the planarbody extendsbeyond the protective hull at the tapering distal edge. Also disclosed hereinis an interface jointfor integrating into a single cable assembly all of (i) a fluid feed, (ii) aneedle movementmechanism, and (iii) an energy feed (e.g. a coaxial cable), and a torquetransfer device forpermitting controlled rotation of the cable assembly within the instrumentchannel of anendoscope. The interface joint and torque transfer device may be integrated asa singlecomponent.
