Duodenal sleeve and conveyor thereof

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 cannula for gastrojejunal diversion and a special transporter thereof, which are used for endoscopically implanting the cannula, diverting gastric contents across the duodenum and directly entering the jejunum, and achieving obesity and The treatment of diabetes belongs to the technical field of medical equipment. Background technique [0002] Obese patients are often accompanied by diabetes, and bariatric surgery with laparoscopic gastric bypass surgery has been shown to improve outcomes in obese patients with postoperative type 2 diabetes. Although it is minimally invasive, it is simple and fast, with short operation time and quick recovery. Patients generally do not take hypoglycemic drugs after surgery to maintain normal blood sugar levels for a long time. Compared with long-term treatment with hypoglycemic drugs, the relative cost is not high, which greatly reduces the economic burden of patients and the socia...
