The thermal excision device which excises the section of lesion organization such as tumor organization at heat

摘要

Device for localized thermal ablation of lesion tissues, particularly tumoral tissues or the like, which device comprises: a probe or needle intended to be positioned with the end tip at the lesion tissue or tumoral tissue area to be removed; which probe or needle support at least a light guide as an elongated member like a thin wire or thread, one of the ends thereof is an end emitting heating electromagnetic energy and which light guide ends at said end of the probe or needle by a tip irradiating said electromagnetic energy, particularly as a laser light and the other end thereof is connected to a source generating the electromagnetic energy; means for controlling the activation/deactivation of the source generating the electromagnetic energy. Characterized in that in combination it comprises means for monitoring the heating action on the lesion tissue area generated by the electromagnetic energy emitted by the irradiating tip inside a volume having a predetermined size and operating on the basis of a transferring function of generated heat on a measuring sensor provided at a predetermined distance and position with respect to the source emitting the electromagnetic irradiation.
