Abstract
A new and improved laparoscopic trocar and sleeve assembly in which the trocar is provided with a transparent tip and accommodates a light telescope for supplying a video console so that while the trocar 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 wall or injury to any of the internal organs located in the abdominal cavity. Once clear visualization is established, conventional laparoscopic procedures can be carried out safely.
