Abstract

The invention provides a balloon dilatation device used for treating cricopharyngeal muscle achalasia, which comprises a hollow soft guide pipe with a closed front end, wherein an appropriate positionin the front of the guide pipe is provided with a balloon dilatation section, an appropriate position at the tail part of the guide pipe is connected with a water supply branch, and a water flow passage is arranged in the wall of the guide pipe for connecting and communicating the watering branch and the balloon dilatation section. The balloon dilatation device for treating the cricopharyngeal muscle achalasia has the advantages of simple operation, safety and reliability.

Description

technical field [0001] The invention relates to a medical device, in particular to a balloon expansion device for treating cricopharyngeal muscle achalasia. Background technique [0002] Cricopharyngeal muscle achalasia is a common disease of the cricopharyngeal muscle. Clinically, patients feel that there is a lump in the throat, or food sticks in the esophagus, coughing, and often have swallowing disorders such as mouth and nose reflux. Its serious consequences are due to the aspiration of food into the lungs, resulting in repeated infections and malnutrition. [0003] The efficacy of balloon dilatation for the treatment of cricopharyngeal achalasia has been clinically proven. In the prior art, there is a precedent for dilatation of the cricopharyngeus muscle with a urinary catheter balloon, but the catheter balloon device cannot locate the position of the cricopharyngeus muscle during treatment, and at the same time, it cannot precisely control the balloon Expansion pre...
