Dilator for esophageal and cardiac stenosis

Introduction of Dilator for Esophageal and Cardiac Stenosis

Esophageal and cardiac stenosis dilators can be classified into the following categories based on the principles and materials used:

1. Airbag expander: This expander consists of one or more airbags, which are inflated to expand the expander, thereby expanding the narrow area of the esophageal cardia. Airbag expanders can be further divided into balloon expanders and airbag expanders.

2. Metal dilator: This dilator is made of metal material and is usually a plastic or metal structure with springs. Expand the esophageal cardia by rotating or compressing the dilator.

3. Water bag expander: This type of expander increases pressure by injecting liquid into the water bag, thereby achieving the effect of dilating the cardia.

4. Instrument dilator: This dilator is made of metal material with an adjustable threaded device. Gradually rotating the threaded device can gradually expand the instrument, thereby expanding the esophageal cardia.

The function and use of esophageal and cardiac stricture dilators

Esophageal and cardiac stenosis dilator is a medical device used to treat esophageal and cardiac stenosis. Its main function is to dilate the site of esophageal and cardiac stenosis, restoring normal patency of food passing through the esophagus to the stomach. The specific usage method is to insert a dilator into the narrow area of the esophageal cardia, and then gradually expand the path of the narrow area through the dilator's expansion function, so that food can pass through smoothly.

Esophageal cardia stenosis refers to the narrowing of the cardia between the esophagus and stomach, which makes it difficult for food to pass through normally. Common causes include gastroesophageal reflux disease, hiatal hernia, etc. Esophageal and cardiac stenosis can cause symptoms such as difficulty swallowing, chest pain, and gastroesophageal reflux. In severe cases, it can even lead to food blockage and suffocation.

The use of a dilator for esophageal and cardiac stenosis can help patients restore normal swallowing function, alleviate or eliminate related symptoms. In general, patients need to undergo multiple expansion treatments, with a certain time interval between each treatment. The expansion process needs to be carried out under the guidance of a doctor, and attention should be paid to avoiding side effects caused by excessive expansion.

In general, the function and purpose of an esophageal and cardiac stenosis dilator is to help treat esophageal and cardiac stenosis, restore normal esophageal patency, alleviate or eliminate related symptoms, and improve the quality of life of patients.

The principle of a dilator for esophageal and cardiac stenosis

Esophageal and cardiac stenosis dilator medical device, used for treating esophageal and cardiac stenosis. Its working principle mainly includes the following aspects:

1. Dilation effect: The dilation device for esophageal and cardiac stenosis expands the narrow area of the esophagus and cardia by inflating the balloon in the dilation device. After the balloon expands, a certain force will be applied to expand the narrow area, restoring normal patency.

2. Traction effect: When the balloon in the dilation instrument expands, it will to a certain extent pull the narrow area, causing it to elongate, thereby reducing or eliminating the symptoms caused by esophageal and cardiac stenosis.

3. Elastic effect: After the balloon expands, it has a certain degree of elasticity, which can make it adhere to the esophageal wall, thereby better transmitting the expansion force and increasing the expansion effect.

In summary, the principle of an esophageal and cardiac stenosis dilator is mainly to treat the site of esophageal and cardiac stenosis through dilation, traction, and elasticity, in order to achieve the goal of restoring normal patency. The specific usage method and expansion strength need to be determined based on the specific situation of the patient and the guidance of the doctor.
