The rod 21 has a rod-shaped member which can push the center of the distal end of the inner fixing member 10c with its distal portion toward the distal end, and with a plurality of engaging step portions 24a are formed on the proximal portion. The engaging member 22 is also provided with a lower engaging portion 25 which can engage with an outer fixing member 10a and an upper engaging portion 26 which can engage one of the engaging step portions 24a of the rod 21.

L'invention concerne un dispositif d'extension de sonde de gastrostomie permettant de faciliter l'insertion ou le retrait d'une sonde de gastrostomie en rendant le degré d'extension de sonde de gastrostomie constant. Ce dispositif d'extension de sonde de gastrostomie (20) est utilisé dans l'insertion et l'extraction d'une sonde de gastrostomie (10) dans/à partir d'un trou (33) formé dans l'abdomen d'un patient, cette sonde (10) comprenant un élément de fixation extérieur (10a) destiné à être installé sur la surface de la peau, un élément de fixation intérieur (10c) placé sur la surface interne de la paroi stomacale, et un élément de sonde (10b) destiné à relier l'élément de fixation extérieur (10a) et l'élément de fixation intérieur (10c), et le dispositif d'extension de sonde de gastrostomie comprend une tige (21) et un élément de couplage (22). La tige (21) comporte un élément en forme de tige qui peut pousser le sang de l'extrémité distale de l'élément de fixation intérieur (10c) avec sa partie distale vers l'extrémité distale, et avec plusieurs parties de l'étape de couplage (24a) qui sont formées sur la partie proximale. L'élément de couplage (22) comprend également une partie de couplage inférieure (25) qui peut se coupler à l'élément de fixation externe (10a) et une partie de couplage supérieure (26) qui peut se coupler à une des parties de l'étape de couplage (24a) de la tige (21).
