Title (EN) METHOD AND APPARATUS FOR MONITORING CRYOSURGICAL OPERATIONS
(FR) PROCEDE ET APPAREIL PERMETTANT DE SURVEILLER DES OPERATIONS CRYOCHIRURGICALES
Abstract:
(EN) A method and system for monitoring the progress of an ice ball produced by a cryoprobe during a surgical procedure measures the complex impedance of the ice ball. An electrical model of the zones in the ice ball is employed to calculate the size of the zones using the complex impedance measurements. The ice ball zones are displayed to assist the surgeon in controlling the cryoprocedure.
(FR) L'invention concerne un procédé et un système permettant de surveiller la progression d'une balle de glace produite par une cryosonde lors d'une opération chirurgicale. Ce procédé et ce système mesurent l'impédance complexe de la balle de glace. Un modèle électrique des zones de la balle de glace permet de calculer la taille des zones à l'aide des mesures d'impédance complexe. Les zones de la balle de glace sont affichées afin d'aider le chirurgien à contrôler l'opération chirurgicale.
