Embodiment Construction

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] The diaphragm and the lower esophageal sphincter (LES) together form the contraction and relaxation function of the gastroesophageal sphincter. The gastroesophageal junction is an anatomically complex valve structure consisting of an extrinsic element (the diaphragmatic crura) and the smooth muscle of the lower esophageal sphincter, which is unique to the esophagus. The gastroesophageal junction (GEJ) is a complex anatomical re...

Abstract

The invention provides an anti-reflux hiatus hernia patch which comprises a substrate, a chimney body and a base plate, the substrate is used for being attached to the diaphragm muscle, the chimney body is used for wrapping the lower section of the esophagus, and the base plate is used for being attached to the cardia; the substrate is arranged at the lower end of the chimney body, and the base plate is arranged at the upper end of the chimney body. By means of the hiatus hernia treatment device, the technical problems that the hiatus hernia operation difficulty is large, the normal anatomical structure of the human body needs to be changed, and the postoperative recurrence rate is high are solved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an anti-reflux hiatal hernia patch. Background technique [0002] Under normal conditions, the esophagus is fixed to the diaphragm so that the stomach cannot be displaced through the hiatus into the mediastinum. The main limiting structures are the phrenoesophageal ligament (phrenoesophageal membrane), and aggregates of posterior structures including the vagus nerve and the root of the left gastric vein and arteries. The phrenoesophageal membrane is elastic, embedded in the esophageal musculature along the periphery, near the squamocolumnar junction, and extends approximately 1 cm above the gastroesophageal junction. This anatomical relationship is disrupted in the presence of a hiatal hernia. [0003] At present, the most widely used biological patch for hiatal hernia repair is the non-cross-linked acellular porcine small intestinal submucosa (SIS) biological patch. Th...
