ABSTRACT:
A scope assembly for an endoscope adapted for use with a portal cannula to provide a generally hemispherically shaped field of view within the body. The scope assembly includes a guiding cannula adapted for rotation within the portal cannula. A distal end of the guiding cannula is bent or offset from a longitudinal axis of the scope assembly. A bendable scope is mounted within the guiding cannula and is adapted for rotation within the guiding cannula. A GRIN lens located at a distal or viewing end of the bendable scope is also offset from the longitudinal axis of the bendable scope such that upon rotation of the guiding cannula or bendable scope a generally hemispherically shaped field of view is scanned.
