Ingestible wireless capsules for enhanced diagnostic inspection of gastrointestinal tract

Mahdi RASOULI, Andy Prima KENCANA, Van An HUYNH, Eng Kiat TING, Joshua Chong Yue LAI, Kai Juan WONG, Su Lim TAN, Soo Jay PHEE

Frontiers of Mechanical Engineering 2011, Volume 6, Issue 1, Pages 40-44 doi: 10.1007/s11465-011-0204-4

Abstract:

Wireless capsule endoscopy has become a common procedure for diagnostic inspection of gastrointestinal tract. This method offers a less-invasive alternative to traditional endoscopy by eliminating uncomfortable procedures of the traditional endoscopy. Moreover, it provides the opportunity for exploring inaccessible areas of the small intestine. Current capsule endoscopes, however, move by peristalsis and are not capable of detailed and on-demand inspection of desired locations. Here, we propose and develop two wireless endoscopes with maneuverable vision systems to enhance diagnosis of gastrointestinal disorders. The vision systems in these capsules are equipped with mechanical actuators to adjust the position of the camera. This may help to cover larger areas of the digestive tract and investigate desired locations. The preliminary experimental results showed that the developed platform could successfully communicate with the external control unit via human body and adjust the position of camera to limited degrees.
