Title
(EN) ELECTROSURGICAL APPARATUS AND METHOD
(FR) APPAREIL ET PROCÉDÉ ÉLECTROCHIRURGICAUX
Abstract
(EN)
Apparatus and methods for electrosurgery are disclosed. In one arrangement, an electrosurgical element and a control system are provided. The electrosurgical element is electrically driven in a first electrical driving mode. The first electrical driving mode is such as to cause heating of human or animal tissue by the electrosurgical element. The heating contributes to modification or cutting of tissue by the electrosurgical element. The electrosurgical element is electrically driven in a second electrical driving mode. An electrical response of the electrosurgical element is measured during the electrical driving of the electrosurgical element in the second electrical driving mode.

La présente invention concerne un appareil et des procédés d’électrochirurgie. Dans un agencement, un élément électrochirurgical et un système de commande sont fournis. L’élément électrochirurgical est électriquement entraîné dans un premier mode d’entraînement électrique. Le premier mode d’entraînement électrique est tel qu’il amène le chauffage du tissu humain ou animal par l’élément électrochirurgical. Le chauffage contribue à la modification ou à la coupe du tissu par l’élément électrochirurgical. L’élément électrochirurgical est électriquement entraîné dans un second mode d’entraînement électrique. Une réponse électrique de l’élément électrochirurgical est mesurée durant l’entraînement électrique de l’élément électrochirurgical dans le second mode d’entraînement électrique.
