Recently micromachine technology has been actively introduced to the endoscope. It makes endoscopes more compact to get into the organs more easily. And also it makes various functions integrated to enhance the ability of endoscopes. This will lead to advanced diagnosis and therapy. As examples of the above, the following devices are introduced; Active bending catheter with SMA(Shape Memory Alloy)realizes accurate bending of the distal end by remote control and ensures clear observation. Micro tactile sensor, which is fabricated by micromachining technique, can measure the hardness of tissue. Ultra-thin video endoscope is the thinnest video endoscope in the world. We developed Ultra-thin video endoscope by using micro fabricating technology and micro assembling technology. Endoscopic Optical Coherence Tomography is a novel technique based on low-coherence interferometery that provides noninvasive, surface, high-resolution imaging of biological ultrastructure. The optical component inside the probe is fabricated using miniaturization technology. Micro confocal scanning microscope is a laser-scanning microscope extremely miniaturized with micromachine technology and is built into the distal end of the probe. It will realize the observation of the cellular architecture of biological tissue with resolution on the micro scale in vivo without biopsies. Micromachine technology has enhanced the diagnostic capability of endoscopes. It enables endoscopes to reach various organs more easily and obtain much more diagnostic information. Consequently, endoscopes can contribute to less-invasive and more precise diagnosis. Technical challenges is continued to realize the Capsule Endoscope as a dream endoscope.
