“…For successful surgical gestures, the surgeon must have access to reliable and rich information acquired from the vision system. Improving the quality of the vision system can be achieved by working on the miniaturization of the vision sensors (as the endoeye endoscope developed by Olympus R ) as well as on the mechanical cameras support (deployment, handling, fixation and extraction systems) [19], [2], [7], [6].…”

“…In flexible endoscopy, wire-based transmission of images can easily reach hundreds of megabits per second (58), and power can be supplied through the scope. For WCE, the power available is determined by onboard battery capacity, and the wireless data transmission rate is on the order of a few megabits per second (59).…”

The gastrointestinal tract is home to some of the most deadly human diseases. Exacerbating the problem is the difficulty of accessing it for diagnosis or intervention and the concomitant patient discomfort. Flexible endoscopy has established itself as the method of choice and its diagnostic accuracy is high, but there remain technical limitations in modern scopes, and the procedure is poorly tolerated by patients, leading to low rates of compliance with screening guidelines. Although advancement in clinical endoscope design has been slow in recent years, a critical mass of enabling technologies is now paving the way for the next generation of gastrointestinal endoscopes. This review describes current endoscopes and provides an overview of innovative flexible scopes and wireless capsules that can enable painless endoscopy and/or enhanced diagnostic and therapeutic capabilities. We provide a perspective on the potential of these new technologies to address the limitations of current endoscopes in mass cancer screening and other contexts and thus to save many lives.

“…The module contained CMOS image sensors, a miniature optical lens, Light-Emitting Diodes (LEDs), and a miniature joint. [3] In 2011, Agrawal introduced an endoscope with outer diameter 5.5 mm. [4] Although thoracic endoscopes still use the conventional hard endoscope, replacement of traditional hard endoscope by electronic thoracic endoscope is just a matter of time.…”

A wireless electronic endoscope that transmits signals by Wi-Fi is developed for use in singlehole endoscopic surgery and future application to natural orifice surgery. The innovative electronic endoscope developed in this study has a disposable design, completely preventing patents from taking risks of cross infection. The main components of the endoscope are a disposable component of the front tip and the hand-held part of the rear tip. The front tip consists of a lens, metallic tube, and electronic joint whereas the rear tip consists of a power switch, image converter, wireless transceiver chip, and antenna. Experimental applications of the wireless electronic endoscope show that after 3 hours and 30 minutes of normal use, the temperature of metallic tube at the front tip averages 45 C. Regarding the measured luminance result, when the focal distance is 5 cm, luminance reaches 1410 lux. In an indoor environment, when the measured distance is 3 m and there is no disruptor, the Wi-Fi transmitted signal of the endoscope is at strength À51 dBm. If the disruptor is established between the sending and receiving ends, signal strength is À53 dBm. Increasing the measured distance to 8 m obtains a signal strength of À74 dBm. Test practical applications indicate that the wireless Wi-Fi electronic endoscope fully meets the needs of surgery room.
