A synthetic patch against reflux esophagitis with radiostimulation

Abstract

The invention relates to the technical field of tissue engineering, in particular to a synthesized patch with a wireless stimulation function and used for resisting reflux esophagitis. The synthesized patch comprises an upper layer, a lower layer and an implant type wireless stimulating device and is characterized in that one side of each of the upper layer and the lower layer is provided with a circular notch, the angle of each circular notch is 270 degrees, the edge part of the upper layer is connected with the edge part of the lower layer to allow the two circular notches to be connected correspondingly, sealed space is formed between the upper layer and the lower layer, and the implant type wireless stimulating device is disposed in the sealed space; the upper layer and the lower layer are made of materials with the shape memory feature, the upper layer is a teflon layer, and the lower layer is an expanded teflon layer. The synthesized patch has the advantages that the synthesized patch can be used to repair expanded esophageal hiatus, the lower esophageal sphincter is stimulated through the wireless stimulating device, the two major causes, namely hiatus hernia and lower esophageal sphincter relaxation, of the reflux esophagitis are treated effectively, and an evident effect is achieved.

Description

technical field [0001] The invention relates to the technical field of tissue engineering, in particular to a synthetic patch for anti-reflux esophagitis with radio stimulation function. Background technique [0002] The etiology of gastroesophageal reflux disease includes contraction dysfunction of the lower esophageal sphincter and hiatal hernia caused by excessive esophageal hiatus. It is a common upper gastrointestinal functional disease caused by repeated acid reflux in the esophagus. 8.8% to 27.8%, although the prevalence of gastroesophageal reflux disease in East Asia is relatively low (2.5% to 7.8%), it is still on the rise. [0003] At present, the classic anti-reflux operation is laparoscopic fundoplication + esophageal hiatus reconstruction, which effectively relieves symptoms by building a wrap around the gastroesophageal junction and strengthening the anti-reflux barrier. This anti-reflux surgery can solve the safety hazards of long-term acid suppression therap...

AI Technical Summary

Problems solved by technology

[0005] However, this method still has the following disadvantages: 1. The mechanism of esophageal reflux includes relaxation of the lower esophageal sphincter and hiatal hernia. Electrical stimulation only solves the problem of relaxation of the esophageal sphincter. For patients with hiatal hernia, this method Still can not completely correct esophageal reflux; 2. Most of the pulse generators buried under the skin are powered by lithium batteries, and the battery life is mostly determined by the implementation time, frequency and related parameters of electrical stimulation. 3. The lower esophagus is constantly wriggling during swallowing, which may cause the electrode to loosen. Once the electrode falls off and touches other organs or blood vessels, it will cause organ damage and massive bleeding under current stimulation, endangering the patient's life
