A remote-controlled laparoscope manipulator system, Naviot™ (Hitachi), is newly developed and introduced to a laparoscopic cholecystectomy for seven patients. This system consists of a specific laparoscope with a zoom lens, a flexible arm, an actuator, a five-bar linkage mechanism, and a hand controller. A surgeon can easily use the zoom lens and move the laparoscope into the eight directions by pushing the buttons of a hand controller. The zoom can be 5.07 magnifications. The moving range is 45° in the horizontal directions and 25° in the vertical ones. All procedures were performed safely and smoothly. We believe that this new system is feasible in clinical use and enables surgeons to perform “solo-surgery” in the near future.
