Probes, Electrothermal Cautery

Definition : Probes designed to apply heat to a body part, either directly to the surface of a tissue or an organ or in a body cavity; they do not deliver electrical current to tissue. These probes typically consist of a high-resistance element (e.g., a wire) attached to a handle that is electrically connected to an electric power-supply unit (a generator) through a cord. The wire is heated by an electrical current delivered by the generator; the heat transferred from the tip of the probe by conduction cuts and/or coagulates the tissue depending on the type of probe used. Two main types of electrothermal cautery probes exist: probes in which the heating component is uncovered (these are typically used for cutting and/or coagulation) and probes in which the heating wire is coated with a nonstick covering (these are used mainly for coagulation and/or control of bleeding). Some probes include an internal irrigation system and/or temperature sensors.
