Abstract
A endoscopic device provides improvements in the endoscopic working space by the use of a semi-tubular hood with an arched top wall and self-supporting walls that allow simultaneous manipulations of dissection, cutting, ligation, and retraction, and the like, without requiring constant application of external force; while enhancing visualization and reducing the need for cleaning the endoscopic lens.
