食管支架置入后常因吞咽动作导致滑移失效，但目前尚无针对食管支架滑移性能的体外评价方法，这导致医疗器械研发工程师及外科医生难以预判食管支架的临床使用效能。针对这一问题，自主研制了食管支架滑移性能测试装置。该装置由仿真食管环境系统、模拟吞咽蠕动系统和软件及控制系统等组成，能在仿真天然食管环境的基础上模拟吞咽蠕动刺激，评估食管支架的抗滑移性。通过对2种自制的食管支架试样进行测试，验证了测试装置的功能性和可重复性。再结合食管支架的径向支撑力和摩擦力测试结果，进一步证实了该装置测试结果可靠，操作简便高效。测试装置可为食管支架的研发和临床筛选提供重要的理论与数据支撑。
Abstract：Esophageal stents after being placed often fail due to migration caused by swallowing. However, at present, there is no in vitro evaluation method for esophageal stents migration performance, which makes it difficult for medical device R&D engineers and surgeons to predict the clinical performance of esophageal stents. To solve this problem, a migration performance test device for esophageal stents was independently developed. The device consisted of the simulated esophageal environment system, simulated swallowing peristaltic system, and software and control system. It could simulate swallowing peristaltic stimulation on the basis of simulated natural esophageal environment to evaluate the anti-migration performance of esophageal stents. By testing two self-made esophageal stent samples, the functionality and repeatability of the testing device were verified. In combination with the radial support force and friction force test results of the esophageal stents, it was further confirmed that the test results of this device were reliable and the operation was simple and efficient. The test device can provide important theoretical and data support for the research and clinical screening of esophageal stents.
