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.
Nouvel ensemble perfectionné comportant un trocart laparoscopique (21) et une gaine (11). Le trocart (21) est pourvu d'une extrémité transparente (22) éventuellement dotée d'une arête coupante (78), et accueille un télescope éclairant (24) relié à une console vidéo, de sorte que lorsqu'on introduit ce trocart (21) par voie chirurgicale dans la cavité abdominale au travers de la paroi abdominale, on peut visualiser l'intervention sur la console vidéo et éviter toute lésion des vaisseaux sanguins de la paroi abdominale ou de tout organe interne situé dans la cavité abdominale. Un manche (32, 33) prévu sur le trocart (21) facilite la manipulation et la régulation de la pénétration de l'extrémité (22) du trocart. Dès que l'on a obtenu une visualisation nette, on peut pratiquer en toute sécurité des interventions laparoscopiques traditionnelles.
