Abstract
Abstract An endoscope has two or more branches and each branch may include a source of illumination and a lens train, fiber optic bundle, or solid state image receiving device. Each branch end is independently manipulable or steerable and thus produces an image from a distinct point of view within the body (e.g., front and side views); the images are juxtaposed on a video monitor for simultaneous viewing by the surgeon. Each branch also includes an operating channel or cannula through which various surgical instruments are passed. A first branch may be used to pass an instrument to the situs of a surgical procedure and a second branch may be used to view that situs from a second, separate point of view. Additionally, the second branch may be used to introduce a second surgical instrument through the second branch cannula to approach the situs of the procedure from the angle of the second branch.
