The invention discloses a nasal gastrointestinal tube guided by an
endoscope, and belongs to the technical field of
medical instruments. The nasal gastrointestinal tube comprises a guide wire, a gastric tube, a jejunal tube, a jejunal tube movable joint and a gastric tube joint. The nasal gastrointestinal tube adopts a tube-in-tube connection mode, the guide wire is placed in the
jejunum through an instrument channel at first, then the near end of the wire is inserted into a
tail-end soft head opening of the jejunal tube, and the nasal gastrointestinal tube is placed in the
stomach or the
jejunum under the guide of the guide wire; the combination of the gastric tube and the jejunal tube is not fixed, when one tube is drawn out, the other tube can be reserved, if the jejunal tube is not needed, the jejunal tube can be completely drawn out, when there is no need to carry out gastric tube decompression, the gastric tube can be drawn out, and the jejunal tube is reserved. Under the condition of the same outer
diameter, a cavity body is larger than a tube cavity of an existing gastrointestinal
nutrition tube, the situation of tube blockage caused when the cavity is too small is avoided, the cost of
medical instruments is reduced, the clinical use is
safer and more convenient, the pain of patients is reduced, and the nasal gastrointestinal tube has great significance on improving the
curative effect.
