[0002] Esophageal cancer is a common digestive tract tumor. The specific symptoms are progressive dysphagia, first it is difficult to swallow dry food, then semi-liquid food, and finally even water and saliva are difficult to swallow, and the patient can only rely on gastric tube to deliver nutrient solution. At present, the only clinical treatment methods for esophageal cancer are surgery, radiotherapy and chemotherapy. This type of patient needs to go through a long recovery period after surgical treatment. During this process, on the one hand, the patient needs to be supplemented with nutrition, and on the other hand, the wound needs to be hemostatic. During the recovery process, anastomotic complications often occur, such as anastomotic leakage, anastomotic bleeding and anastomotic stenosis. These complications not only increase the patient's pain, but also affect the patient's recovery and quality of life, and also bring huge economic burden to the patient. At present, surgical treatment methods such as reconstruction or expansion of the anastomosis are mainly used to treat anastomotic complications, but the surgical trauma is large and the risk is high.
[0003] In the prior art, nasogastric tube feeding is used for nutritional supplementation and drug spraying; the use of certain drugs such as endothelial growth factor can promote the growth of the mucosa of the anastomosis on the one hand, and inhibit the growth of smooth muscle on the other hand, and prevent anastomotic leakage and stenosis. However, the esophageal anastomosis is in the body, and topical drugs cannot reach it accurately. For example, in the utility model patent application of patent CN220025626U, a new type of gastric tube with the function of spraying drugs to the esophagus, drugs are sprayed on the lesion site for treatment through a drug delivery tube and a ring tube, but because the ring tube is fixed on the gastric tube, it is impossible to achieve the purpose of real-time adjustment and precise spraying of drugs according to the patient's surgical anastomosis position.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.
[0020] A nutrition tube with the function of spraying medicine into the esophagus comprises an inner tube 1, the inner side of the inner tube 1 is a nutrient solution cavity 2, an outer side of the inner tube 1 is sleeved with an outer tube 5, an annular channel 3 is provided between the inner tube 1 and the outer tube 5, a medicine annular tube 4 is provided at the bottom of the annular channel 3, the medicine annular tube 4 is vertically fixedly connected with a medicine input tube 8, the medicine annular tube 4 is communicated with the medicine input tube 8, more than four medicine spraying tubes 7 are uniformly protruded and distributed on the outer side of the medicine annular tube 4 in the circumferential direction; a plurality of longitudinal straight slide grooves 6 are embedded in the side wall of the outer tube 5, and the medicine spraying tube 7 is slidably connected to the inside of the slide groove 6.
[0021] The above-mentioned liquid medicine annular tube 4 is also fixedly connected to a camera connecting tube 9 in the vertical direction. A camera 10 is provided on one end of the liquid medicine annular tube 4 close to the camera connecting tube 9. The camera 10 is slidably connected in the slide groove 6. The camera connecting tube 9 is provided with a power line and a signal line for connecting the camera 10.
[0022] The liquid medicine annular tube 4 of the above-mentioned nutrition tube is provided with 2-4 liquid medicine input tubes 8, so as to facilitate the input of different liquid medicines according to the needs.
