Abstract
Provided is an endoscope system including an elongated tube with one or more channels extending in a longitudinal direction along the elongated tube. The channels allow inserting of a viewing device for obtaining images from the distal end, inserting of surgical instruments to operate at the distal end, or passing of materials such as air or water. The channel for inserting the viewing device is enclosed or has a cover at the distal end of the elongated tube, such that the viewing device has no direct contact of body tissues, thereby eliminating the need for sterilization. Also provided is a safe and economical method for conducting endoscopy involving one-time use of a tube to keep the viewing device from directly contacting the body tissues.
