Novel nutrient canal with petal-shaped esophageal dilatation balloon

The utility model discloses a novel nutrient canal with a petal-shaped esophageal dilatation balloon. The novel nutrient canal comprises a nutrient canal body and the petal-shaped dilatation balloon which is attached to the nutrient canal body. The outer side face of the nutrient canal is coated with the dilatation balloon, the cross section of the dilatation balloon is in a petal shape, and a V-shaped gap is formed between every two petals. According to the structure, the petal-shaped balloon is used for physically supporting the esophageal stenosis section after esophageal peripheral mucosa dissection (ESD) or other intractable esophageal stenosis for a long time, and a certain space is reserved between the balloon and the inner wall of the esophagus through the gaps between petals of the petal-shaped balloon, so that the esophageal stenosis can be achieved. Therefore, enough time and space are provided for normal esophageal mucosa to crawl and grow towards a narrow esophageal wound surface, the difficult p
