摘要

背景/目的:结肠支架置入术在急性恶性结肠梗阻的治疗中发挥着至关重要的作用。自膨胀金属支架(SEMS)的使用越来越多,不同部位的结肠梗阻也带来了各种挑战,这些都凸显了有效培训结肠支架置入术的重要性:方法:模拟器的所有部件均采用硅胶成型技术和三维打印技术制造。来自计算机断层扫描和结肠镜检查图像的三维图像被转换成立体光刻格式。丙烯腈-丁二烯-苯乙烯共聚物已被用于熔融沉积建模来生产模塑件:结果:模拟器复制了从直肠到盲肠的大肠,模仿了人体结肠的纹理和形状。该模拟器可进行结肠镜插入、盲肠插管、肠环缩小和狭窄区域内支架植入的培训。四个部位(直肠、乙状结肠、降结肠和升结肠)的可互换狭窄模块很容易组装起来进行训练。这些模块将肿瘤轮廓和血管结构与半透明中心整合在一起,可在支架植入过程中实时观察。使用可重复使用的 SEMS,支架插入和扩张的演示始终保持成功和可重复:这种创新型模拟器可在不同地点提供安全的结肠支架置入练习,在实际操作过程中提高操作者的熟练程度,从而改善临床效果。

Development of colonic stent simulator using three-dimensional printing technique: a simulator development study in Korea.

Background/aims: Colonic stenting plays a vital role in the management of acute malignant colonic obstruction. The increasing use of self-expandable metal stents (SEMS) and the diverse challenges posed by colonic obstruction at various locations underscore the importance of effective training for colonic stent placement.

Methods: All the components of the simulator were manufactured using silicone molding techniques in conjunction with three-dimensional (3D) printing. 3D images sourced from computed tomography scans and colonoscopy images were converted into a stereolithography format. Acrylonitrile butadiene styrene copolymers have been used in fused deposition modeling to produce moldings.

Results: The simulator replicated the large intestine from the rectum to the cecum, mimicking the texture and shape of the human colon. It enables training for colonoscopy insertion, cecum intubation, loop reduction, and stenting within stenotic areas. Interchangeable stenotic modules for four sites (rectum, sigmoid colon, descending colon, and ascending colon) were easily assembled for training. These modules integrate tumor contours and blood vessel structures with a translucent center, allowing real-time visualization during stenting. Successful and repeatable demonstrations of stent insertion and expansion using the reusable SEMS were consistently achieved.

Conclusions: This innovative simulator offers a secure colonic stenting practice across various locations, potentially enhancing clinical outcomes by improving operator proficiency during actual procedures.
