Abstract

In this study, side viewing endoscope has been developed for cancer therapy. Polypectomy is a technique for treatment of early cancer and polyp in the gut. Endoscope can not observe backside of the lesion, because only front viewing is available. This device is available to add on for endoscope to observe the backside of the lesion. The device consists of a CMOS imager, two LEDs and a mirror to observe side view in front of CMOS imager. This device has hydraulic actuator or shape memory alloy (SMA) wire as bending mechanism. The external diameter of fabricated devices is 2.5 mm. The fabricated side viewing endoscope achieved to observe the backside of the lesion in the stomach model.
