The invention relates to a medical device including a trocar with a hollow tip for the passage of a camera, a light source and a miniature camera at the tip thereof, which transmits images to an LCD screen. The invention also includes two or more working channels on the sides thereof, for the introduction of surgical equipment for the removal of the appendix or other similarly sized structures. The camera is connected to a cable which is, in turn, connected to an LCD screen, such that the surgeon has the impression of looking at the patient's abdominal cavity through a window.
