Abstract

　L'invention concerne un système chirurgical (1) qui est pourvu d'une pile (200), d'un outil de traitement (100) et d'une unité de liaison (300). La pile (200) émet, comme première tension, une tension continue ayant une première valeur de tension. La pile est installée de façon amovible sur l'outil de traitement (100), celui-ci étant configuré de façon à amener l'énergie de traitement à agir sur un tissu biologique, en utilisant la première tension comme source d'énergie. L'unité de liaison (300) peut être reliée de façon détachable à l'outil de traitement à la place de la pile et comprend un circuit de conversion pour recevoir l'entrée d'une seconde tension continue ou alternative ayant une seconde valeur de tension, différente de la première valeur de tension, et pour convertir la seconde valeur de tension en première valeur de tension. La tension continue ayant la première valeur de tension convertie par le circuit de conversion est fournie à l'outil de traitement.
