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.
