    摘要： An electrosurgical instrument (402) for delivering radiofrequency (RF) electromagnetic (EM) energy and microwave frequency EM energy from a coaxial feed cable (406) through an instrument tip into tissue. The instrument tip comprises a dielectric body (416) separating first and second conductive elements, which act as active and return electrodes to convey the RF EM radiation by conduction, and as an antenna to radiate the microwave EM radiation. The instrument also has a fluid feed (424) incorporated into its tip, e.g. in an additional dielectric element (422) mounted on the underside of the tip, for delivering fluid. The delivered fluid may be a gas plasma to assist treatment or a liquid to plump up a tissue region before treatment. The instrument may fit in an endoscope.

    摘要： Presented are an apparatus, method and electrosurgical device for surgical procedures. An exemplary apparatus includes a body comprising a longitudinal axis and an electrical wire maintained within the body extending along the longitudinal axis, and an electrode extending from a distal end of the body operably coupled to the electrical wire, the electrode with the electrical wire operable to conduct a flow of current at a plurality of levels. The apparatus further includes a first button arranged on an external surface of the body, the first button operable for selecting the flow of current at each one of the plurality of levels through the electrical wire and the electrode, and a second button arranged on the external surface of the body adjacent the first button, the second button operable activate and deactivate the flow of current to the electrode.
