SELF-PROPELLED DEVICE FOR ENDOSCOPE |
摘要 |
A self-propelled device nips an endless belt between a worm wheel and a driven roller. The endless belt is circulated by rotating the worm wheel, and thereby an insertion section of an endoscope advances and retreats inside a body cavity. The driven roller has a width larger than the worm wheel, and is provided with a pair of flanges at both ends. The worm wheel is disposed between the pair of flanges. When the endless belt is nipped between the worm wheel and the driven roller, the endless belt is deformed by the pair of flanges. |
