Abstract
An improved endoscope has been provided which includes an elongated cylindrical shell housing with a transparent window at the distal end thereof. A removable core has an objective endoscope lens or optics at the distal end thereof and an image sensor mounted within the distal end of the core. A transmitting electronic cable with multiple conductors each has a distal end connected to the image sensor circuit board and a proximal end connected to a video control unit. Signals are transmitted from the control unit to the video monitor which displays the image. A sterile separable channel section, removably receives the core in a defined relationship and has at least one longitudinal channel for transmitting fluids or for receiving an operative instrument or carrying light transmitting fiber. A flexible tube is connected to the proximal end of the channel for supplying fluid or for manipulating the operative instrument from a remote location. The separable channel section is disposable after use on a patient. Light transmitting fibers can be integral with the housing or core or inserted into at least one of the channels in the channel or sheath section.
