| description | The utility model discloses an anti-displacement type particle cavity drainage catheter, which relates to the technical field of medical instruments, and comprises a catheter body with a drainage cavity and a particle cavity, a plurality of elastic film sleeves are arranged on the inner wall of the particle cavity at intervals along the axial direction, the elastic film sleeves are in the shape of circular truncated cones, and the elastic film sleeves are arranged on the inner wall of the particle cavity. The flaring end of each elastic film sleeve is connected to the inner wall of the corresponding particle cavity channel, the necking end of each elastic film sleeve is naturally placed in the corresponding particle cavity channel and is close to the drainage end of the tube body, a particle cavity bag is formed between every two adjacent elastic film sleeves, and the length of each particle cavity bag is larger than or equal to that of each radioactive particle. The inner diameter of the particle cavity chan |
