Esophageal and cardia stenosis dilator

Introduction to esophageal and  cardia stenosis dilators

Esophageal and cardia stenosis dilator is a medical device used to treat esophageal and cardia stenosis. Esophageal cardia stenosis refers to the narrowing or contraction of the opening of the esophageal cardia (the tube between the esophagus and stomach), which prevents food from passing through smoothly.

Esophageal and cardia stenosis dilators are generally made of a flexible metal wire mesh, similar to spring steel wires or balloons. It is usually inserted into the patient's body through the mouth or esophagus, and then located at the site of cardiac stenosis. Once the target position is reached, the dilator will improve the stenosis of the cardia by unfolding or dilating. This allows food to smoothly re-enter the stomach through the esophagus.

The process of using esophageal and cardia stenosis dilators usually requires endoscopic guidance or local anesthesia. The doctor may gradually increase the diameter of the dilator during the operation to achieve the best dilation effect. This process may require multiple operations, with intervals between each operation, to ensure that the dilator can gradually improve the degree of esophageal and cardiac stenosis.
