Abstract

The invention relates to a human orificial pipe substitute with baffle edge. Wherein, it is formed by support tube, connector, flexible film and baffle edge; the flexible film is adhered on the support tube; the baffle edge is connected to the end of support tube; the connector is fixed on the support tube. The inventive support tube can effectively avoid around organism to contract to be neck; the connector can effectively reduce the creep of normal orificial pipe to avoid affecting the anastomotic stoma, to obtain firm connection; and the baffle edge can effectively disperse the stress at the anastomotic stoma, to avoid narrow anastomotic stoma. The invention can be made into artificial gullet or trachea.

Description

technical field

[0001] The invention relates to a substitute for a human cavity, in particular to a substitute for an esophagus or a trachea, that is, an artificial esophagus or an artificial trachea. Background technique

[0002] In the prior art, when the esophagus needs to be resected due to tumors, it is usually solved by lifting the stomach or intestinal tract and anastomosis with the proximal end of the esophagus to reconstruct the digestive tract. Complications; when tracheal lesions need to resect the trachea of ​​more than 3cm, an ideal substitute for tracheal reconstruction is urgently needed clinically.

[0003] The inventor discloses a substitute for the reconstruction of the human lumen in the Chinese patent ZL01107515.5 (patent name: artificial lumen substitute), especially a substitute for reconstruction of the esophagus or trachea. Its main structure is: It is composed of a tubular body made of memory alloy smart elements and connecting pieces, the connectin...
