How To Make A Dilator Device

1. The present disclosure relates to the technical field of medical devices, and in particular, to a dilator device.

Background technique:

2. At present, when the hospital performs esophageal biopsy and treatment for patients, the relationship between the front end of the gastroscope and the target position is often changed due to esophageal peristalsis, and sometimes the position change leads to inaccurate sampling or complications. When performing esophagus, cardia, pylorus expansion or stent placement, multiple steps such as indwelling a guide wire, pulling out a gastroscope, and reinserting a balloon or a carbon-stripe dilator are often required. Patients are often in great pain. For example, the public number is cn2380244y It is disclosed in the Chinese patent of "Balloon Dilation Therapy Device for Achalasia Cardiac Cardiac Cardiac Disease". The hollow catheter of the dilator is inserted along the guide wire and delivered along the guide wire to the site of the desired dilation.

3. Therefore, the inventors found that, according to the above technical solution, the patient needs to go through the steps of indwelling the guide wire, pulling out the gastroscope, inserting the balloon, and pulling out the guide wire and the balloon, causing the patient to suffer unbearably.
