Abstract: An auxiliary tubing probe for converting a monopolar electrosurgery probe having a main electrode at one end, into a bipolar electrosurgery probe. The auxiliary probe has an inner electrically insulated tube in which the monopolar electrosurgery probe is slidably inserted. An electric conductor extends externally over and along the inner insulated tube. An auxiliary electrode connected to the electric conductor projects forward away from the inner tube, in such a manner as to be adjacent to the main electrode when the monopolar electrosurgery probe has been inserted in the auxiliary probe. An outer electric insulator covers the electric conductor from the first extremity to the second extremity. The insertion of the auxiliary probe over the monopolar electrosurgery probe, and electricity going through the auxiliary electrosurgery probe and monopolar electrosurgery probe, allows conversion of the monopolar electrosurgery probe into a bipolar electrosurgery probe.

Abstract: A multifunctional surgical instrument for use in laparoscopic surgery, including a rigid hollow tube, or trocar, mounted on a pistol-grip shaped holder in which a cartridge may be removably mounted, incorporating valves and tubes for connection to a source of vacuum and a source of flushing liquid. The instrument is very simple yet efficient in structure, very handy and easy to use, and designed to allow fast and easy interchange of a tube by another tube incorporating or not electrodes or laser fibers. It can be used through a cannula, not only for irrigation or suction of physiological matter but also for suction of gas or vapors, electrocautery, laparoscopy or laser surgery.
