Abstract

An elongated electrosurgical instrument (1) serves to at least cutting and coagulating tissue of a patient during surgery by application of electrical energy supplied from an electrosurgical generator to a surgical site. The electrosurgical instrument has a hollow elongated main body with and electrode means (3). Suction means comprises a suction channel (27), a first suction port (40) facing the electrode means (3), and a second suction port (41) provided with a suction tubing (11) in communication with a vacuum source. A switch means (4) is provided on the elongated main body (2) and arranged for supplying the electrical energy to the first means (3) in response to operating an actuator (4;4′). The switch means (5) comprises at least one first electrical contact (42;43) and at least one second electrical contact (44). The electrical contacts have main body parts configured as conductive sheet components (50), wherein the at least one first electrical contact provided superjacent and spaced apart in order to switch said contacts between an open state and a closed state by operating the actuator (4;4′). The switch means is very flat and does not extend into the suction channel nor outside the elongated main body, thereby providing a streamlined, thin outline of the instrument that fit well into the surgeon's hand.
