Given that a surgeon's technical skills affect not only short- but also long-term outcomes, adequate surgical training is very important. We developed the world's first training simulator for laparoscopic right hemicolectomy that does not use animal tissue, called COLOMASTER, which was designed to accurately reproduce the anatomical and membrane structures of the human body. Here, we report the features of COLOMASTER.
Dry polyester fibers were used to reproduce the multilayered membrane structure, and the adhesive strength of the layers was controlled using bonding technology, allowing realistic peeling techniques. Hydrogel was used to achieve electrical conductivity.
COLOMASTER allows surgeons to simulate the entire surgical step and practice complete mesocolic excision, central vascular ligation, and intracorporeal anastomosis, the importance of which has been reported in recent years.
We present the world's first right hemicolectomy simulator that does not use animal tissue and believe that it will contribute to efficient off-the-job training.
鉴于外科医生的技术技能不仅会影响短期结果，还会影响长期结果，充分的外科培训非常重要。我们开发了世界上首个不使用动物组织的腹腔镜右半结肠切除术训练模拟器，称为COLOMASTER，其旨在精确再现人体的解剖和膜结构。在此，我们报告COLOMASTER的特点。
使用干燥的聚酯纤维来再现多层膜结构，并使用粘结技术控制各层之间的粘结强度，从而实现逼真的剥离技术。使用水凝胶来实现导电性。
COLOMASTER使外科医生能够模拟整个手术步骤，并练习完整的结肠系膜切除、中央血管结扎和体内吻合术，近年来这些操作的重要性已得到报道。
我们展示了世界上首个不使用动物组织的右半结肠切除术模拟器，并相信它将有助于高效的在职培训。
