A radio frequency tissue ablation apparatus for use on a horizontal support surface in connection with a medical procedure on a patient. A portable carrying case having a carrying handle is provided and is adapted to rest upon a horizontal surface. The portable carrying case has a cover with an inner surface and is movable between a generally vertical open position and a generally horizontal closed position when the portable carrying case is resting on the horizontal support surface. The portable carrying case has a keyboard and a primary display panel disposed adjacent the keyboard under the cover when the cover is in a closed position and is accessible visually and physically when the cover is in an open position. The primary display panel includes a plurality of groups of numerical indicia and a plurality of switches associated with at least certain of the groups of numerical indicia for establishing criteria for those certain groups of numerical indicia. The primary display panel includes an additional switch for selecting automatic or manual operation. A graphic display panel is carried by the inner surface of the cover. Electrical circuitry, including a radio frequency generator and a control computer, is disposed within the portable carrying case and is coupled to the keyboard, the primary display panel and the graphic display panel. The portable carrying case has a plurality of ports accessible externally in communication with the electrical circuitry in the portable carrying case. A probe is coupled to one of the ports carrying an electrode and is adapted to penetrate tissue.
