Abstract

La présente invention concerne un ensemble élément de protection à diamètre variable pour une chirurgie mini-invasive, qui comprend : une pluralité de nervures présentant la forme d'une plaque plate avec une largeur spécifiée et une longueur spécifiée ; et des éléments joints rétractables, dont chacun relie l'une de la pluralité de nervures et une nervure adjacente à celle-ci, la pluralité de nervures formant une forme cylindrique comportant un canal formé à l'intérieur de celle-ci en raison de la répétition d'un motif dans lequel le bord d'une nervure et le bord de la nervure adjacente se chevauchent mutuellement, la pluralité de nervures, qui forment la forme cylindrique, sont insérées à travers une ouverture d'une personne qui subit une procédure chirurgicale, et le diamètre interne de la forme cylindrique varie selon l'extension et la rétractation de l'élément joint. En tant que tel, l'ensemble élément de protection à diamètre variable fait varier le diamètre interne de celui-ci pour des applications à divers sites chirurgicaux, ce qui permet d'obtenir une procédure chirurgicale stable et précise.
