Gastric tube guiding catheter special for laparoscopic sleeve gastrectomy

Abstract

The invention discloses a gastric tube guiding catheter special for laparoscopic sleeve gastrectomy. The gastric tube guiding catheter is characterized by comprising a pulling piece arranged in a gastric tube guiding catheter body. The thin side wall of the portion near the tail end of the gastric tube guiding catheter body is bent towards the thick side wall of the catheter body when being pulledby the pulling piece. The arrangement of the pulling piece realizes the adjustment of the bending degree of the guiding tail end of the gastric tube guiding catheter body relative to the gastric tubeguiding catheter body. The diameter of the tail end of the guiding catheter body is reduced, and therefore the guiding catheter can pass through the duodenum from the pylorus conveniently, and balloons are arranged at the tail end of the guiding catheter body; the balloons are expanded after being inflated and then can be used for fixing the gastric tube for facilitating surgery operation. An indicator lamp is arranged at the tail end so that the position of the gastric tube can be conveniently determined during surgery. The catheter body is arranged at a gastric terminal part, the balloons are arranged in sections, and different balloons are inflated to guide different parts which are 2 cm, 4 cm and 6 cm away from the pylorus, so that a precise starting point for cutting the stomach is conveniently selected according to different conditions of patients during surgery.

Description

technical field [0001] The invention relates to the technical field of medical instruments, more specifically, it relates to a gastric tube guiding tube specially used for laparoscopic sleeve gastrectomy. Background technique [0002] The principle of laparoscopic sleeve gastrectomy is to cut the greater curvature of the stomach vertically through a laparoscope, so that a small gastric pouch of about 50cc-100cc can be formed in the stomach, which can hold about 2-4 ounces of food . The method of laparoscopic sleeve gastrectomy is to use laparoscope along the direction of the lesser curvature of the stomach to preserve the antrum 2-6cm above the pylorus, the gastric body and the gastroesophageal junction. Most of the stomach on the side of the greater curvature was resected along the long axis of the stomach, and all the fundus was removed, so that the remaining stomach was "banana-shaped" with a volume of about 50-100ml. The principle of laparoscopic sleeve gastrectomy is ...

AI Technical Summary

Problems solved by technology

In the existing gastric tube guide tube, the curvature of the leading end of the gastric tube guide tube relative to the tube body of the gastric tube guide tube is fixed. During the operation, it cannot be adjusted adaptively in the face of different gastric curvatures. , which sometimes makes the operation more complicated
