This invention is a new and improved laparoscopic trocar (21) and sleeve assembly in which the trocar (21) is provided with a transparent tip (22) that can include a blade edge (78), and accommodates a light telescope (24) for supplying a video console, so that while the trocar (21) is being surgically inserted through the abdominal wall and into the abdominal cavity, visualization on the video console will be possible to avoid injury to blood vessels in the abdominal cavity or injury to any of the internal organs located in the abdominal cavity. A handle (32, 33) provided on the trocar (21) facilitates manipulation and control of the trocar tip (22) penetration. Once clear visualization is established, conventional laparoscopic procedures can be carried out safely. |
