Bipolar mapping suction device

Abstract

A bipolar mapping suction instrument and a system for suctioning fluids and tissue and for monitoring nerve tissue are provided. The suction instrument includes a cannula unit, including electrically conductive inner and outer cannula tubes and insulation. The electrically conductive inner cannula tube is arranged concentrically in the outer cannula tube which can be insulated from the exterior. The electrically conductive inner cannula tube is mechanically connected to a handpiece and/or a first interface. The electrically conductive inner and outer cannula tubes are respectively electrically connected to first and second poles of a bipolar electrical connection of a second interface. The insulation is concentrically arranged between the outer cannula tube and the inner cannula tube and electrically isolates the outer cannula tube from the inner cannula tube.
