Problems solved by technology

However, due to trauma, changes in anatomical structure and various complications such as malnutrition, postprandial hypoglycemia, infection, and even death caused by surgery, many patients are afraid of surgery. As a result, among all patients suitable for surgery, only Less than 1% of patients end up having surgery

Embodiment 1

[0044] According to the helical structure strength ratio (the number of helical rings) of the skeleton 1 structure with a ratio of 3:1, a helical structure is formed, and the nickel-titanium memory alloy wire is wound by a monofilament, and the diameter of the monofilament is 0.30mm. The opening in the stomach of the device of the present invention is closed, with a diameter of 4.5 cm. After the diameter is gradually increased in the long axis direction of 0.5 cm, the diameter of the spiral ring reaches 5.5 cm. After that, the diameter is gradually reduced to 2.5cm, is the junction of gastric pyloric tube segment 3 and pyloric orifice segment 4, and the covering tube 2 has a large number of circular spaces. The positive and negative phase filaments of the helical ring structure of the gastric pyloric segment 3 continuously cross the pyloric segment 4 with a length of 2.0 cm along the axial direction, and continue to wind in the duodenal lumen in a ratio of positive and negative...

Embodiment 2

[0046] On the basis of Example 1, according to the strength ratio of the helical structure (the number of helical loops) is the backbone 1 structure of the ratio of 2: 1, forming "major groove" and "minor groove" such as the DNA helical structure, in the duodenal bulb The length of the lumen to the axial distance of 1.0 cm exists in the lumen of the duodenum, and its diameter is from 2.0 cm to 3.0 cm. Afterwards, the winding wire, which accounts for 1 / 3 of the density of the spiral ring, continues in the axial direction to the descending segment of the duodenum, and the diameter of the spiral ring is 2.5 cm. The coating tube 2 covers the skeleton 1 located in the duodenal lumen from the beginning of the small intestine segment 5, and continues to extend to the proximal end of the jejunum. The length of the intestinal segment is 60.0 cm.

Embodiment 3

[0048] According to the skeleton 1 structure of the gastric pyloric tube segment 3 as a two-segment helical structure, nickel-titanium memory alloy wire is wound with a monofilament, and the diameter of the monofilament is 0.30mm. The opening in the stomach of the device of the present invention is closed, with a diameter of 4.5 cm. After the diameter is gradually increased in the long axis direction of 0.5 cm, the diameter of the spiral ring reaches 5.5 cm. After that, the diameter is gradually reduced by a distance of 1.0 cm in the long axis direction. to 5.0cm, and then the skeleton filaments go directly along the axial direction (the side of the greater curvature of the stomach), forming a 1.0cm-long range without a helical structure, and then winding into a helical structure again. The diameter of the helical ring gradually decreases from 4.5cm to 3.0cm. Link pylori segment 4. The stomach covering tube 2 has a large number of circular spaces. The skeleton filament of the...

Abstract

Type 2 diabetes mellitus and obesity are important diseases which are severe threats to human health in the world. Although the Type 2 diabetes mellitus and obesity have been treated and prevented by many measures, these measures have inevitable shortcomings. The invention discloses an instrument for delaying gastric emptying and regulating pancreatic metabolism. The instrument mainly consists of a skeleton (1) and a coated tube (2), and can be divided into a gastric pyloric tube section (3), pyloric exit (4) and small intestine (5) from the axial direction. By implanting the instrument, gastric emptying can be delayed, early satiety can be induced, the gastric content can be turned into duodenal distal segment or jejunum proximal segment, and the pancreatic metabolism can be regulated. With the instrument of the invention, the mechanical stimulation and injury of gastrointestinal casing to mucous membrane of stomach and intestines can be reduced to a greatest extent, and the complications after implantation, such as abdominal pain, vomit, etc., can be reduced.

Description

technical field [0001] The invention relates to a device for delaying gastric emptying and regulating intestinal and pancreatic metabolism, which is used for implanting in the stomach and upper small intestine with the aid of endoscopes, etc., to treat diseases such as obesity, type 2 diabetes and its complications, and belongs to the technical field of medical devices . Background technique [0002] Type 2 diabetes and obesity are common diseases that seriously threaten human health in the world. Although there are many measures for the treatment and intervention of type 2 diabetes and obesity, it is well known that these measures have unavoidable deficiencies. Changing lifestyle behavior is the basic treatment for type 2 diabetes and obesity, but many people have poor compliance. None of the drugs can significantly affect the progress of the disease, and can only temporarily restore normal blood sugar, and the curative effect will decrease with the prolongation of the me...
