Abstract
The present invention relates to endoscope system having means to provide simultaneous forward and rear views of a hollow organ. It comprises of first image assembly comprising of forward image lens and forward illumination source disposed at distal end of the endoscope and; second image assembly comprising of rear image lens and rear illumination source disposed on rear view module operatively engaged with the endoscope. Upon deployment of rear view module, rear image lens and rear illumination source face backwards with respect to the endoscope; and in some embodiments of the invention; face towards forward image lens and illumination source disposed at the distal end of the endoscope. According one aspect of the invention, means is provided to prevent interference between the forward image lens of the endoscope and rear illumination source of the rear view module; and between rear image lens of the rear view module and forward illumination source of the endoscope.
