Abstract

La présente invention concerne un mandrin (2) pour un cathéter (40), en particulier une sonde de gastrostomie, ce mandrin comprenant une partie supérieure (4) et une partie inférieure (6) en forme de tige pouvant être insérée dans le cathéter (40). L'invention concerne par ailleurs un instrument de mesure de longueur permettant de déterminer la longueur d'un canal de stomie. Ce mandrin (2) et cet instrument de mesure de longueur (16) se caractérisent en ce qu'ils comportent un canal longitudinal (8). Ce canal longitudinal permet d'enfiler le cathéter, au moyen du mandrin, ou l'instrument de mesure de longueur sur un fil guide introduit dans le canal de stomie, ce fil guide définissant un chemin pour l'introduction du cathéter ou de l'instrument de mesure de longueur de sorte que la sonde de gastrostomie puisse être mise en place de manière sûre et sans risque de blessure, même si le canal de stomie ne présente pas une forme idéale. L'invention concerne en outre un ensemble comprenant un mandrin et un instrument de mesure de longueur de ce type.
