Problems solved by technology

However, the ordinary gastric tube used in the current operation is thinner, cannot be close to the gastric tissue, is easy to shift, and cannot play an effective role in gastric emptying and guiding, which leads to the inability to accurately evaluate the size of the stomach. In addition, some Ordinary gastric tubes are made of relatively hard materials, which can easily damage gastric tissue during insertion, causing gastric bleeding or even perforation
Utility model patent: 201420701284.2, which discloses a visible sleeve gastrectomy gastric calibration tube. Three optical fibers are embedded in the tube wall of the gastric calibration tube. The embedded optical fibers affect the flexibility of the catheter, and the catheter is easy to shift during use. The positioning is not accurate, and the optical fiber is easier to break, resulting in accidents during the operation.
In addition, only three (integrated) suction holes and flushing holes are set on the catheter, which is easy to cause blockage during use, which brings certain difficulties to the operation; the nozzle of the gastric calibration tube is open, and gastric juice is easy to leak from it. Ejection, causing surgical pollution; moreover, the catheter is provided with a semiconductor light-emitting device connected with an optical fiber, which also increases the manufacturing cost

Abstract

The invention discloses a gastric tube special for precise laparoscopic sleeve gastrectomy. The gastric tube comprises a soft, elastic and graduated gastric tube body, wherein a gastric tube plug and a gastric tube connector are respectively connected to the front end and the tail end of the gastric tube body, a light-emitting wire body is formed in the tube wall on one side of the gastric tube body from the head to the tail, the light-emitting wire body can be connected with a power supply and provided with a plurality of lamp beads, and the tube wall, avoiding the light-emitting wire body, of the front haft section of the gastric tube body is provided with 1-3 rows of lateral holes with intervals of 10mm. The gastric tube has the advantages that the light-emitting wire body is formed in the tube wall of the gastric tube, the gastric tube with the light-emitting wire body closely attaches to the lesser curvature tissue, the size of the sleeve stomach can be evaluated precisely, the subtotal gastrectomy position can be identified conveniently under a laparoscope by the aid of the gastric tube with the light-emitting wire body, the to-be-reserved sleeve stomach is positioned precisely, and the effect of the precise laparoscopic sleeve gastrectomy is increased; the head of the gastric tube plug is of a soft and obtuse circular shape, so that stomach damage can be lowered effectively.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to a sleeve gastrectomy operation equipment, in particular to a special gastric tube for precise laparoscopic sleeve gastrectomy. Background technique [0002] Precise Laparoscopic Sleeve Gastrectomy (PLSG) is one of the most commonly used surgical methods for the treatment of obesity and metabolic diseases. Because of its simple operation, less trauma, less complications and definite effect, it is favored by patients and surgeons. With the development of the economy, China's obese population is increasing rapidly, and this operation reflects an excellent development prospect. The special gastric tube for precise laparoscopic sleeve gastrectomy can be used as a routine equipment in the operation. It can make a more accurate evaluation for the surgeon to determine the size of the gastrectomy, and it plays an important role in the effect of the operation and the reduction of co...
