Description

Technical Field

[0001] The invention relates to the technical field of simulation training devices, in particular to an esophageal atresia surgery simulation training device. Background Art

[0002] Congenital esophageal atresia often coexists with tracheoesophageal fistula, which is caused by abnormal embryonic development and is a more serious congenital malformation. The operation is difficult and has high complications. Acquired pathogenic factors including trauma, foreign bodies, tumors, infections and iatrogenic factors (air bag compression, esophageal stent placement, etc.) can also cause tracheoesophageal fistula, making the operation more complicated.

[0003] Since esophageal atresia surgery is relatively complicated and difficult to operate, inexperienced doctors often cause high complications and surgical risks. Doctors need to use models for more skilled simulation training before actual operation. Commonly used models are animal models, such as the Chinese patent with publication number CN216933589U, which discloses a device for establishing a minimally invasive tracheoesophageal fistula animal model. Although simulation training can be performed, there are many types of esophageal atresia, such as esophageal atresia without fistula, esophageal atresia proximal fistula, esophageal atresia distal fistula, esophageal atresia proximal fistula and esophageal atresia without atresia but with H or Y-shaped fistula. The existing model does not have a good disassembly function, which makes it inconvenient to replace the esophageal atresia model. In addition, there is a certain gap between the animal model and the human body structure, which has certain limitations and brings inconvenience to the simulation training work.

[0004] The existing esophageal atresia surgery simulation training model does not have a good disassembly function and has certain limitations, making it inconvenient for medical staff to use. Summary of the invention
