Embodiment 1

[0016] Example 1: see figure 1 , a "Y"-shaped integrated digestive tract stent, its main feature is that it includes an intestinal side tube 2 arranged in a "Y" shape on an esophageal tube 1, and the angle between the two intestinal side tubes is 60°.

[0017] The esophageal tube 1 and the intestinal side tube 2 are MTN nickel-titanium memory alloy braided by nickel-titanium memory alloy wires, and the outer or inner surfaces of the esophageal tube 1 and the intestinal side tube 2 are exposed.

[0018] The esophageal tube 1 and the intestinal side tube 2 are integrated in a "Y" shape, and the intestinal side tube 2 is a bundled bracket.

[0019] The upper opening of the esophageal tube 1 is set as a bell mouth, with a diameter of 18mm and a length of 4cm.

[0020] The lower opening of the intestinal side tube is cup-shaped, the diameter of the intestinal side tube is 18 mm, and the length is 4 cm.

Embodiment 2

[0021] Example 2: see figure 1 , a "Y"-shaped integrated digestive tract stent, its main feature is that it includes an intestinal side tube 2 arranged in a "Y" shape on an esophageal tube 1, and the angle between the two intestinal side tubes is 90°.

[0022] The esophageal tube 1 and the intestinal side tube 2 are made of MTN nickel-titanium memory alloy, braided by nickel-titanium memory alloy wire, the outer surface or inner surface of the esophageal tube 1 and the intestinal side tube 2 are partially covered with a film, and the material and thickness of the film It is the existing digestive tract covered stent technology.

Abstract

The invention relates to a medical appliance, in particular to an integral digestive tract stent. A Y-shaped integral digestive tract stent is mainly characterized by comprising an esophagus tube (1) and Y-shaped intestinal lateral tubes (2) arranged on the esophagus tube (1), wherein an included angle between the two intestinal lateral tubes (2) is 60 degrees to 100 degrees. The Y-shaped integral digestive tract stent solves the problem of digestive tract obstruction caused by stoma focus recurrence of BI-II type anastomosis after the total gastrectomy, and has the advantages that the operation is simple, safe and noninvasive; the eating problem of a patient is solved after one-step implanting; an upper opening of the stent is in a horn opening shape; the stent displacement cannot be easily caused; and two lower openings are in cup opening shapes, and the intestinal mucosa injury cannot be easily caused.

Description

technical field [0001] The invention relates to a medical appliance, in particular to an integrated digestive tract bracket. Background technique [0002] Gastric cancer is a common and frequently-occurring disease. Total gastrectomy and Bi-II anastomosis are common surgical procedures for radical gastrectomy. Postoperative recurrence of anastomotic lesions causes digestive tract obstruction. The common solution is digestive tract stent placement. into treatment or ostomy. However, there is currently a lack of digestive tract stents suitable for Bier-II anastomosis after total gastrectomy. Traditional fistula has the following disadvantages: [0003] (1) Fistula is an invasive treatment with high risks. [0004] (2) The postoperative fistula is prone to infection, and the nutrition tube is easy to prolapse. [0005] (3) After the operation, the patient can only inject liquid diet from the nutrition tube, and cannot eat from the mouth, which reduces the quality of life of...
