step-by-step esophageal dilatation balloon

Abstract

The invention discloses a step-by-step esophageal dilatation balloon, which can gradually push the balloon to the corresponding part of the esophagus. The desired part, and reduce the patient's discomfort. The key points of the technical solution are: a step-by-step esophageal dilatation balloon, including a catheter, a balloon and a propulsion device for gradually pushing the catheter into the esophagus, and the catheter passes through the interior of the propulsion device; the propulsion device includes a housing, a propulsion tube, an extrusion Compression sleeve, spring and button, the push tube is located inside the housing, the catheter is located in the push tube, the front end of the push tube is provided with a chuck that can be automatically opened, and the chuck shrinks in the extrusion sleeve in a natural state. The retraction of the head is fixed in the push tube; press the button to push the push tube to drive the catheter forward, and then the clip comes out of the extrusion sleeve and opens. After the button is released, the push tube is reset by the action of the spring, and the clip re-enters Squeeze sleeve.

Description

technical field [0001] The invention relates to the field of gastroenterology instruments, in particular to a step-by-step esophageal dilatation balloon. Background technique [0002] Esophageal stenosis is a digestive tract disease that can be caused by congenital esophageal stenosis (also known as congenital esophageal ring and esophageal web). In addition, secondary esophageal stenosis is more common in esophageal tumors, esophageal motility disorders, and anastomosis after esophagogastric anastomosis Stricture, esophagitis or scar stenosis caused by burns, etc. Dysphagia is the main symptom of esophageal stricture, in addition to pain when swallowing, weight loss, and regurgitation of food after eating. [0003] Esophageal stenosis is usually treated by balloon dilation. Balloon dilation is to insert a balloon that can be filled with air or water into the esophagus. To achieve the purpose of treating stenosis. [0004] However, the balloon used in the existing balloon...

AI Technical Summary

Problems solved by technology

[0005] In the existing balloon dilatation, with the assistance of X-ray angiography, the doctor manually pushes the catheter with the balloon into the patient's esophagus. Since the digestive tract in the human body is relatively sensitive, the balloon must be kept Slow and uniform speed, but it is difficult to grasp the strength and maintain stability when pushing with bare hands, which will not only lead to inaccurate position of the pushed balloon, but also may bring strong pain to the patient
