近年来，胃肠道疾病急剧增加。因此，正在开发内窥镜技术来诊断和治疗这些疾病。生物材料特性是开发内窥镜设备特别是胶囊型内窥镜的重要信息。过去几十年来，获取胃肠道材料特性的实验都是在体外状态下进行的。因此，消化器官的材料特性不是体内测试结果，而是体外结果。在这项研究中，我们设计、开发和制造了生物材料特性测量（BMPM）系统。测量系统由探测装置、筋装置和吸力部分组成。当传感模块根据肌腱控制突出时，探针测量从生物材料传输的力，同时抽吸装置抓住器官。通过使用该系统，我们可以测量局部变形力和刺穿力。测得的变形和刺穿力数据可用于胶囊型内窥镜的运动和夹紧机构设计。为了评估 BMPM 的有效性，我们对猪的食道、胃和结肠进行了手术。总之，我们可以在体外状态下测量每个器官的材料特性，而无需解剖消化器官。一些体内测试结果有望用于使用所提出的 BMPM 系统设计内窥镜设备。
Recently, diseases in gastro-intestinal tract have drastically increased. As a result, endoscopic technologies are being developed to diagnose and treat these diseases. Biomaterial property is essential information to develop endoscopic devices especially capsule type endoscope. For the past decades, experiments to obtain material property of gastro-intestinal tract are performed on in-vitro state. Therefore, material properties of digestive organs are not in-vivo test result but in-vitro result. In this research, we design, develop, and fabricate a bio-material property measurement (BMPM) system. The measuring system consists of a probing device, tendon device and suction part. The probe measures the force transmitted from the biomaterial as the sensing module protrudes based on the tendon controls, while the suction device seizes the organ. By using the system, we can measure the local deformation force and the piercing force. The measured deformation and piercing force data can be used for the locomotive and clamping mechanism design of the capsule type endoscope. In order to evaluate the validity of the BMPM, we perform the operation in an esophagus, stomach and colon of a pig. In conclusion, we could measure each organ's material properties under in-vitro state without dissection of digestive organs. Some in-vivo test results are expected to design endoscopic devices using the proposed BMPM system.
