Abstract

L'objet de l'invention sert à positionner de manière solide et stable un instrument d'insertion dans une cavité corporelle. Un instrument de guidage est muni d'un corps d'accouplement accouplant une première canule de guidage d'une première lumière d'aiguille dans une cavité corporelle et une seconde canule de guidage d'une seconde lumière d'aiguille dans la cavité corporelle. Une première section de retenue et de fixation de la première canule et une seconde section de retenue et de fixation de la seconde canule sont disposées sur le corps d'accouplement. La première et la seconde section de retenue retiennent et fixent la première et la seconde canule, respectivement, dans un état où la relation de position relative entre la première et la seconde canule est fixe.
