Capsule endoscopy (CE) is indicated as a first-line clinical examination for the detection of small-bowel pathology, and there is an ever-growing drive for it to become a method for the screening of the entire gastrointestinal tract (GI). Although CE's main function is diagnosis, the research for therapeutic capabilities has intensified to make therapeutic capsule endoscopy (TCE) a target within reach. This manuscript presents the research evolution of CE and TCE through the last 5 years and describes notable problems, as well as clinical and technological challenges to overcome. This review also reports the state-of-the-art of capsule devices with a focus on CE research prototypes promising an enhanced diagnostic yield (DY) and treatment. Lastly, this article provides an overview of the research progress made in software for enhancing DY by increasing the accuracy of abnormality detection and lesion localisation.

“…It has the capability to stretch into to sampling point, bite and cutting off and withdrawing the sample into capsule body by doing this process automatically [4]. This system is relatively large considering the size regulations approved by food and drugs administration in 2001, but apparently is can be useful in the large intestine.…”

Capsule endoscope is commercial design product used as a medical device for endoscopy test in the small intestine preferably. This paper presented a novel conceptual design and power mechanism in order to perform a capsule endoscope robot with micro-hydraulic biopsy tools system. The capsule endoscope presented can moves as active device, powered externally by an electro-magnetic actuation system (EMA). The EMA system can be frequency adjust to activate the micro-hydraulic pump as the main power generator to perform the micro-actuator and/or micro-biopsy tool. The conceptual design is focused in two capsule containers; these are proposed to be able to obtain additional space for the biopsy tools. Preliminary test of the micro-pump power by EMA system are presented for future application of capsule endoscope with active motion maneuvers and micro-biopsy tools operation in real-time.
