Description

Guiding and supporting stomach tube capable of preventing gastric juice from splashing

Technical Field

The utility model relates to the technical field of gastric tubes, in particular to a guiding and supporting gastric tube capable of preventing gastric juice from splashing.

Background

Currently, the most widely accepted procedures for weight loss metabolic surgery include laparoscopic gastric sleeve resection and laparoscopic gastric bypass.

The gastric sleeve resection operation is relatively simple to operate, the laparoscope is utilized to keep the antrum above the pylorus of 2-6cm along the running direction of the greater curvature of the stomach, the majority of the stomach is resected along the long axis of the stomach, the whole fundus is resected, the residual stomach is in a banana shape, the most weight reduction operation is currently applied, but the resection size of the stomach is accurately mastered in the sleeve gastric resection operation, a gastric tube is required to be used as a support and a guide, and because the common gastric tube is thinner, if the common gastric tube is used as the support and the guide, the stricture is easy to cause, but the gastric tube used as the guide support cannot be too large, otherwise the resection is easy to cause too little, so that the effect is bad;

the gastric bypass operation is a compound operation for reducing intake and absorption, which is characterized in that a small gastric pouch is built at the upper part of the stomach to limit food intake, and then a far-end jejunum is anastomosed with the small gastric pouch to bypass the large part of the stomach, the duodenum and the upper jejunum, so that the food intake and absorption are greatly controlled, but the size of the small gastric pouch in the gastric bypass must be precisely controlled to be about 15-30 milliliters according to the requirement, gastrointestinal anastomosis cannot be completed if the size is too small, and re-enlargement is easy to be caused if the size is too large, so that an auxiliary device is needed to measure the size of the small gastric pouch in the operation, and the anastomosis size is ensured to meet the requirement;

in addition, in the operation process, gastric juice can be splashed out when the gastric tube is placed, and the gastric juice splashes onto the body and even the face of an operator, so that the surrounding environment and medical staff are polluted, and the current gastric tube or the adapter at the tail end is not provided with a closing device to quickly block the gastric juice splashing, so that a device capable of blocking the gastric tube is needed to be found, the time is wasted, and the clinical operation is inconvenient.

In summary, the existing gastric tube has the problems that gastric juice splashing can not be blocked quickly, and the size of the small gastric pouch, the size of the anastomotic stoma and the size of the resected stomach can not be measured accurately.
