Abstract

An new and improved laparoscopic trocar (12) and sleeve assembly (11) in which the trocar (12) is provided with a transpar-ent tip (22) and accommodated a light telescope for supplying a video console so that while the trocar (12) is being surgically in-serted through the adbodimal wall and into the abdominal cavity, visualization on the video console will be possible to avoid inju-ry to blood vessels in the abdominal cavity wall or injury to any of the internal organs located in the addominal cavity. Once clear visualization is established, conventional laparoscopic procedures can be carried out safely.
