食管裂孔疝是常见的消化系统良性疾病，目前主要的外科治疗手段为腹腔镜下食管裂孔疝修补术。该手术操作难度较大，对术者基本功要求高。3D打印模型的腹腔镜下手术培训，一定程度上弥补传统教学与实践操作之间的不足，不再受培训场地及时间上的限制。我中心通过3D打印技术制作食管裂孔疝修补Dry Lab模型，对外科医师进行培训，为手术规范化标准化提供保证。

Hiatal hernia is a common benign disease of digestive system. The main surgical treatment is laparoscopic repair of hiatal hernia. The operation of this operation is difficult and requires high basic skills of the surgeon. The laparoscopic surgery training of 3D printing models makes up for the deficiency between traditional teaching and practical operation to a certain extent, and is not limited by the time of the training venue. Our center produced a Dry Lab model for hiatal hernia repair through 3D printing technology, trained surgeons, and provided guarantees for the standardization of surgery.
