Abstract: Objective To discuss the development of a multifunctional and multipoint fixed support drainage device for the digestive tract, as well as the effect of its application on animal experimental models and patients. Methods The digestive tract multifunctional and multipoint fixed support drainage device is designed according to the requirements of the various gastrointestinal surgery and interventional procedures. It has metal flaps and airbags to achieve multi point fixation. The cuffs and shears are used to achieve endoscopic removal. And through different tube diameters and lengths, surgeons can achieve different surgical purposes. Results A multifunctional and multipoint fixed support drainage device for the digestive tract was successfully designed and developed. The application experiment of the winged pancreatico-intestinal supporting drainage tube on animal models and patients, showed lower drainage fluid amylase level, faster amylase recovery speed, and better perioperative safety. Conclusion The support drainage device has the characteristics of simple operation, firm fixation, and good controllability of removal. It is an ideal choice among support drainage tubes in gastrointestinal surgery and interventional operations.
