Abstract

Dispositif conçu pour être monté sur une extrémité ouverte d'un tube de trocart. Le dispositif comprend un tube de fixation sensiblement cylindrique utilisable pour être couplé à l'extrémité ouverte du tube de trocart. Le dispositif peut également comprendre une mâchoire s'étendant à l'opposé du tube de fixation et ayant une extrémité distale sensiblement conique située à l'opposé du tube de fixation. La mâchoire comporte des parois latérales correspondant à une partie de la circonférence du tube. Le dispositif peut également comprendre une gaine s'étendant à l'opposé du tube de fixation et ayant une extrémité distale qui s'étend vers l'extrémité distale sensiblement conique de la mâchoire. La gaine a des parois latérales correspondant à une autre partie de la circonférence du tube et les parois latérales de la gaine et les parois latérales de la mâchoire étant sollicitées l'une vers l'autre. Le dispositif peut comprendre au moins un mécanisme de verrouillage actionnable pour verrouiller la mâchoire dans une configuration fermée.
