Title
(EN) ELECTROSURGICAL INSTRUMENT
(FR) INSTRUMENT ÉLECTROCHIRURGICAL
Abstract
(EN)
An electrosurgical instrument having a radiating tip portion capable performing tissue ablation using microwave energy and electroporation (e.g. non-thermal irreversible electroporation) in a minimally invasive manner. The electrosurgical instrument may be used to perform microwave ablation and electroporation separately (e.g. sequentially) or simultaneously. The radiating tip portion may be dimensioned to be suitable for insertion into a pancreas via a surgical scoping device, to provide a rapid and accurate alternative to known RF ablation techniques. By enabling tumours within the pancreas to be treated using a minimally invasive procedure, it may be a viable option to use ablation and/or electroporation treatment for both curative as well as palliative reasons.
(FR)
L'invention concerne un instrument électrochirurgical présentant une partie de pointe rayonnante en mesure de réaliser une ablation de tissu à l'aide d'énergie à micro-ondes et d'électroporation (par exemple une électroporation irréversible non thermique) d'une manière minimalement invasive. L'instrument électrochirurgical peut être utilisé pour réaliser une ablation par micro-ondes et une électroporation séparément (par exemple séquentiellement) ou simultanément. La partie de pointe rayonnante peut être dimensionnée pour pouvoir être insérée de manière appropriée dans un pancréas par l'intermédiaire d'un dispositif d'endoscopie chirurgicale, pour fournir une variante rapide et précise aux techniques d'ablation par RF connues. Grâce à la possibilité de traitement de tumeurs dans le pancréas à l'aide d'une procédure minimalement invasive, l'utilisation d'un traitement d'ablation et/ou d'électroporation peut être une option viable, pour des raisons à la fois curatives et palliatives.
