A first balloon (42) is fitted to an insertion section (12) of an endoscope (10), and the insertion section (12) is fixed to an intestinal canal (90) by inflating the first balloon (42). The insertion assisting tool (70) covers the insertion section (12), and is pushed to a tip end portion (46) side along the insertion section (12). When the insertion assisting tool (70) is pushed to the limit state, an indicator (100) provided at a surface of the insertion section (12) appears, and the limit state can be recognized. <IMAGE> |
