Abstract

The invention discloses a removable multi-purpose medical airway stent. The airway stent comprises a hollow cylindrical body, and handles are arranged at the ends of the hollow cylindrical body. The handles are arranged at one end or two ends of the hollow cylindrical body. The handles are V-shaped handles protruding to the inner part of the hollow cylindrical body. The handles facilitating recovery extend to the inner part of the body and are arranged convexly; and even if granulation is proliferated, the handles are not embedded into the granulation and are not required to be taken out by instruments. The conventional stent body is improved, and the stent is easy to implement; in operative treatment of benign airway stenosis and airway-esophageal fistula occlusion and later rehabilitation, the stent is prevented from sliding and shifting, and granulation proliferation is retarded; and the stent is convenient to take out, so that the pain of a patient in later take-out operation is greatly reduced, and secondary injury caused by the operation is avoided.

Description

Technical field

[0001] The present invention relates to the field of medical equipment, in particular to a removable multi-purpose medical airway stent for treating benign airway stenosis, airway-esophageal fistula occlusion and the like. Background technique

[0002] Benign airway stenosis, airway-esophageal fistula and other benign diseases, the stent is placed for a period of time, and the stent needs to be removed after the disease is resolved.

[0003] In the prior art, metal stents, especially nickel-titanium memory alloy stents, are usually used in the treatment of esophageal stenosis, tracheal stenosis, biliary tract stenosis, and blood vessel stenosis. These medical stents have achieved good clinical results. The curative effect has been more and more widely used in the past ten years.

[0004] However, when these bare stents are used to treat stenosis caused by malignant tumors, because the malignant tumor grows faster, the tumor tissue will pass through the metal mesh to ...
