A testing environment that imitates gastric geometry and contractile activity is necessary to analyse and validate endoluminal surgical robotic devices developed for gastric pathologies.To Oven Door Lock achieve this goal, a silicone stomach model and a mechanical setup to simulate gastric contractile motion were designed and fabricated.The developed stomach simulator was validated and its usefulness was demonstrated by means of internal pressure measurements and self-assembly tests of Gun Blue mock-ups of capsule devices.
The results demonstrated that the stomach simulator is helpful for quantitative evaluation of endoluminal robotic devices before in-vitro/in-vivo experiments.
