Embodiment 1

[0035] A duodenal cannula is composed of a metal skeleton 1 and an outer cannula 2 wrapped around the metal skeleton 1 .

[0036] Three large and dense spiral rings are made of memory alloy wire monofilament in the duodenal cavity segment of the metal skeleton, with a length of 5 cm and an approximate funnel shape. After expansion, it matches the anatomical structure of the duodenal cavity 13 . The metal wire of the duodenal bulb cavity segment 3 of the metal skeleton is continuously extended and made into a relatively small diameter and sparse helical ring. This segment is the posterior segment 4 of the duodenal bulb of the metal skeleton, which is used to be placed in the descending duodenum. part 14 , horizontal part 15 and rising part 16 . The back segment 4 of the metal skeleton duodenal bulb is 10cm long.

[0037] The top and bottom ends of the metal skeleton 1 are provided with a circular annular closing 6, and the annular closing 6 is made of memory alloy wire monofil...

Abstract

The invention provides a duodenal sleeve which is composed of a metal framework and an outer sleeve coated outside the metal framework. The metal framework is of a spiral ring structure and divided into a duodenal spherical cavity section for the metal framework and a duodenal spherical rear section for the metal framework; the spiral ring of the duodenal spherical cavity section for the metal framework is bigger and denser than that of the duodenal spherical rear section for the metal framework; the spiral ring structure of the duodenal spherical cavity section for the metal framework is in a bowl or funnel shape; the top and the bottom of the metal framework are equipped with circular or oval annular closed opening; and the outer sleeve is coated outside the metal framework and the lower end thereof is longer than the bottom end of the metal framework. The invention further provides a conveyor for the duodenal sleeve, comprising a plastic hose, wherein, longitudinal cracks are arranged on the wall of the plastic hose from the head end to the tail end thereof. The duodenal sleeve is used for transporting stomach effluents from a stomach pylorus, replaces gastric bypass operation,avoids that the stomach effluents are directly digested, absorbed and metabolized in duodenum, and treats adiposis and diabetes.

Description

technical field [0001] The invention relates to a duodenal sleeve for gastrojejunal diversion and a special conveyor thereof, which are used for implanting the sleeve under the endoscope, diverting gastric contents across the duodenum and directly into the jejunum, so as to realize the prevention of obesity and obesity. The treatment of diabetes belongs to the technical field of medical devices. Background technique [0002] Obese patients are often associated with diabetes, and bariatric surgery laparoscopic gastric bypass surgery has been shown to improve outcomes in obese patients with type 2 diabetes after surgery. Although it is minimally invasive, simple and quick, the operation time is short, and the recovery is fast. Patients generally no longer take hypoglycemic drugs after surgery to maintain normal blood sugar levels for a long time. Compared with long-term hypoglycemic drug treatment, the relative cost is not high, which greatly reduces the economic burden of p...
