Title (EN) RADIALLY EXPANDABLE CANNULA SYSTEM
(FR) SYSTÈME DE CANULE RADIALEMENT EXTENSIBLE
Abstract:
(EN) A radially expandable trocar, port or cannula system is provided for use in minimally invasive surgeries. The cannula creates a port access with an initial small internal diameter. The passage of the cannula devices is defined by a plurality of elongate rigid members. A number of mechanisms are provided for expanding the passage of the cannula devices, by moving the plurality of elongate rigid members towards a larger radial location, thereby creating a larger internal diameter for the port. The elongate rigid members can be prevented from unintended movement when the system is at the un-expanded state, during expansion and when it is expanded to the desired larger diameter. Example embodiments include methods of preventing gas loss from the tissue that would occur through the gaps created during expansion.
(FR) L'invention concerne un système de trocart, d'orifice ou de canule radialement extensible destiné à être utilisé dans des chirurgies mini-invasives. La canule crée un orifice d'accès ayant un petit diamètre interne initial. Le passage des dispositifs de canule est défini par une pluralité d'éléments rigides allongés. Un certain nombre de mécanismes sont prévus pour étendre le passage des dispositifs de canule, en déplaçant la pluralité d'éléments rigides allongés vers un emplacement radial plus grand, créant ainsi un diamètre interne plus grand pour l'orifice. Les éléments rigides allongés peuvent être empêchés de se déplacer accidentellement lorsque le système est dans l'état non étendu, pendant l'extension et lorsqu'il est étendu au diamètre plus grand souhaité. Des modes de réalisation à titre d'exemple comprennent des procédés pour prévenir une perte de gaz à partir du tissu qui se produirait à travers les espaces créés pendant l'extension.
