Abstract

L'invention concerne un article opératoire (11) destiné à une introduction transitoire dans le corps (67) d'un patient (69) lors d'une intervention chirurgicale sur le patient (69), l'article opératoire (11) comprenant : un transpondeur passif (17) équipé d'un dispositif de couplage (32) pour le couplage sans fil du transpondeur (17) à un système de lecture (43) et d'un dispositif de commutation (29), relié électriquement au dispositif de couplage (32). Le transpondeur (17) est agencé afin d'alimenter en énergie le dispositif de commutation (29) via un champ alternatif électromagnétique généré par le système de lecture (43) et de former, au moyen du champ alternatif, une liaison de communication avec le système de lecture (43). Pour obtenir un article opératoire (11) qui peut être capté de manière particulièrement fiable dans le corps du patient, selon l'invention, le champ alternatif présente une fréquence de 860 MHz à 960 MHz et le dispositif de couplage (32) est réalisé sous forme d'un enroulement (33) et deux extrémités (31) du bobinage (33) sont reliées au dispositif de commutation (29) de manière telle qu'un champ proche magnétique généré par le système de lecture (43) au niveau du dispositif de couplage (32) alimente le dispositif de commutation (29) en énergie et forme la liaison de communication.
