摘要: | In the recent past, the introduction of miniaturized image sensors with low power consumption, based on complementary metal oxide semiconductor (CMOS) technology, has allowed the invention of an ingestible wireless capsule for the visualization of the small intestine mucosa. These capsules received approval from US Food and Drug Administration (FDA) and gained momentum because they are more successful than traditional techniques of diagnosis of small intestine disorders. However, the present device still suffers from several limitations: they move passively by exploiting peristalsis, are not able to stop controllably for a prolonged diagnosis, they receive power from an internal battery with a short battery life, and their usage is restricted to one organ, either the small bowel or the esophagus. The steady progresses in many branches of engineering, including micro- electromechanical systems (MEMS), are envisaged to affect the performances of capsular endoscope. In 2004 an esophagus-specific capsule was launched, while a solution for colon is still under development. The near future foreshadows capsules that are able to pass actively through the whole gastrointestinal tract, retrieve views from all organs, and perform drug delivery and tissue sampling. In the near future, the advent of robotics could lead to autonomous medical platforms, equipped with the most advanced solutions in terms of MEMS for therapy and diagnosis of the digestive tract. In this thesis, our project team developed an advanced prototype of a capsule endoscope guided by an external magnetic control system (MCS) that is highly effective, low in cost, and safe. |
