A device and method are provided for sealing and joining or cutting tissue, which is particularly suitable for laparoscopic and endoscopic surgery. The device 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 maximize tissue seal strength while minimizing collateral tissue damage. The device 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 dispositif permettant de sceller et d'assembler ou de couper des tissus, le dispositif étant particulièrement approprié pour une chirurgie laparoscopique ou endoscopique. Le dispositif fait appel à une application régulée d'une combinaison de chaleur et de pression pour sceller des tissus contigus, assembler des tissus contigus, ou anastomoser des tissus, les tissus étant chauffés pendant un temps optimal et à une température optimale sous une pression optimale pour maximiser la force de scellement des tissus tout en minimisant les dommages indirects causés aux tissus. Le dispositif de la présente invention est léger, donc portable, et est particulièrement indiqué dans des conditions ordinaires où une source d'énergie extérieure peut ne pas être facilement disponible.
