An instrument (56, 92, 210) and method are provided for sealing and joining or hemostatically dividing tissue, which is particularly suitable for laparoscopic and endoscopic surgery. The instrument makes use of the controlled application of a combination of heat and pressure to seal adjacent tissues, to join adjacent tissues, or to anastomose tissues, whereby tissue is heated for an optimal time and at an optimal temperature under optimal pressure to miximize tissue seal strength while minimizing collateral tissue damage. The instrument of the present invention is lightweight and therefore portable, and is particularly useful in field conditions where a source of external power may not be readily available.
L'invention concerne un instrument (56, 92, 210) et un procédé pour le scellement et le raccordement ou la division hémostatique des tissus, particulièrement adapté à la chirurgie par laparoscopie et endoscopie. Le principe de l'instrument est une application contrôlée de chaleur et de pression combinées, pour le scellement et le raccordement de tissus adjacents, ou pour le traitement de tissus qui s'anastomosent. On chauffe les tissus selon une durée et une température optimales, sous une pression optimale, afin de porter à son maximum la force de scellement des tissus, tout en réduisant au minimum les dégâts aux tissus de type collatéral. L'instrument est léger, ce qui le rend portable, et il est particulièrement utile dans les conditions de pratique où une source d'alimentation externe n'est pas facilement accessible.
