Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more particularly to a visual multi-purpose decompression feeding tube. Background Art

[0002] Gastric cancer, pancreatic head cancer, gallbladder cancer and duodenal cancer are common malignant tumors in the digestive tract, with an incidence rate accounting for more than 50% of digestive tract tumors. Roux-Y anastomosis and Billroth II gastroenterostomy are common surgical procedures for treatment. In order to reduce the probability of occurrence of situations such as duodenal stump leakage, choledochojejunostomy leakage or gastroenterostomy leakage, a decompression operation is usually required at the input end of the anastomosis.

[0003] Gastrointestinal decompression is a commonly used nursing operation technique in general surgery. Its purpose is to drain the accumulated fluid in the stomach and the accumulated gas in the gastrointestinal tract, relieve abdominal distension and the tension of the suture site, and facilitate wound healing. It is a treatment method that uses the principle of negative pressure suction to suck out the accumulated gas and liquid in the gastrointestinal tract to reduce the pressure in the gastrointestinal tract, improve the blood circulation of the gastrointestinal wall, facilitate the limitation of inflammation, and drain the accumulated fluid in the stomach and the accumulated gas in the gastrointestinal tract. A feeding tube is required for decompression, and the feeding tube can also help patients who cannot swallow to deliver necessary water and food under special circumstances. However, the current feeding tube can only provide the effect of decompression and cannot simultaneously deliver enteral nutrition to the output end of the anastomosis; the existing feeding tube cannot simultaneously have the functions of decompression and visualization; the flexibility of the camera adjustment of the existing feeding tube needs to be improved.

[0004] Therefore, how to provide a visual multi-purpose decompression feeding tube that can simultaneously meet gastrointestinal decompression, enteral nutrition delivery and visualization, and has more flexible camera viewing angle adjustment is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the present invention provides a visual multi-purpose decompression feeding tube, aiming to solve one of the problems in the above background art, and simultaneously meet gastrointestinal decompression, enteral nutrition delivery and visualization, and has more flexible camera viewing angle adjustment.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:
