Abstract

The device in present invention belongs to medical surgical instrument field, is a placing auxiliary device for duodenum nutrition tube in gastroesophageal anastomosis via chest. The device comprises a main body A and a cover plate B; a longitudinal anastomosis hole and a transverse chimeric structure are provided between the main body A and the cover plate B to for assembling and disassembling; and a section of hollow circular tube is formed after assembling. The device of the present invention has the advantages of simple structure, easy operation, convenient cleaning and disinfection; and can safely fast accurately assist the nutrition tube to place into enteric cavity of duodenum in gastroesophageal anastomosis via chest. The invention achieves the advantages of simple production technology, low product cost and conveniently obtained material.

Description

1. Technical field [0001] The invention relates to a device for thoracic surgery, which can safely and quickly assist soft feeding tubes to be accurately placed in the duodenum cavity during transthoracic gastroesophageal anastomosis. 2. Background technology [0002] At present, there are two methods of early nutritional supplementation after radical resection of esophageal cancer: intravenous nutrition and enteral nutrition. Intravenous nutrition is simple to operate, but it is expensive, which is not conducive to the rapid recovery of gastrointestinal digestive function, and complications such as phlebitis may occur at the same time. Enteral nutrition is cheap, conforms to the normal physiological characteristics of the body, and can promote the recovery of digestive tract function. It is the most ideal nutritional supplement method after esophageal cancer surgery. The premise of this type of enteral nutrition is to place a soft tube infused with food in the duodenum or ...
