Endoscopes are required to have good course guidance, traceability, excellent interface with an operator, improved access due to reduced frictional force on lumen tissue, increased patient comfort, and the like. An endoscopic imaging system includes a reusable control cabinet having a number of actuators that control the orientation of a lightweight endoscope connectable to the control cabinet. This endoscope is used and arranged for one patient. The endoscope includes an illumination mechanism, an image sensor, and a long shaft having one or more holes installed therein. An articulation joint at the distal end of the endoscope directs the distal end by an actuator in the control cabinet. Because the endoscope is coated with a hydrophilic coating that reduces the coefficient of friction and is lightweight, there is less force to advance the endoscope to the desired location inside the patient.
