Abstract

The invention relates to the technical field of medical devices, in particular to an alimentary canal stent and a manufacturing process thereof. The alimentary canal comprises a main body, a first support portion and a second support portion; The main body, the first support portion and the second support portion are formed of degradable polymer material by 3D printing, the first support portion and the second support portion are provided at both ends of the main body, and the first support portion and the second support portion are used for matching and abutting with the digestive tract portto support the digestive tract. So as to alleviate the technical problem that the stent needs to be removed by a second operation after being used, thereby increasing the burden of the patient in theprior art.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a stent for the digestive tract and a manufacturing process thereof. Background technique [0002] Gastrointestinal stents are implanted by doctors into the lumen of the human digestive tract that is obstructed or perforated due to disease through technical means, so as to expand and re-canalize the narrow or occluded local lumen. It is an implant that seals the perforated or damaged fistula. Invasive medical devices. [0003] The currently commonly used digestive tract stents are metal stents with fixed specifications, which can play a personalized supporting role according to the shape, size and lesion site of each lumen structure in the patient's digestive tract, and after the pathological conditions such as stenosis and perforating fistula are cured, need Carrying out secondary surgery to the patient will take out the stent, which increases the burden on the patient....
