Abstract
Abstract An endoscope comprises a sheath, an articulation section adjacent to its distal tip, and two or more separate optical channels that produce two or more distinct views. Each of the optical channels comprises an objective lens and a means of capturing and/or viewing the image. The objective lens or lenses of the optical channel that produces the first distinct view, is located at a first location on the distal tip. The objective lens or lenses of the optical channel that produces the second distinct view is located at a second location on the proximal end of the articulation section or on the sheath of the endoscope adjacent to or located proximally of the articulation section.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
170 words
An endoscope comprising: a single continuous shaft including, a sheath, an articulation section attached to a distal end of said sheath and, a distal tip attached to a distal end of said articulation section, and two or more separate optical channels that produce two or more distinct views, each of said optical channels comprising an objective lens, located at a distal end of said respective optical channel and a means of capturing and/or viewing the image; wherein the objective lens of the separate optical channel, which produces the first of said distinct views is located at a first location, said first location located on said distal tip, and the objective lens of the optical channel, which produces the second of said distinct views is located at a second location, said second location located either on a proximal end of said articulation section or on the sheath of said endoscope; wherein the distance between said first location and said second location, measured along the longitudinal axis of said endoscope, is fixed.
Claim 2
Dependent Claim
170 words
An endoscope comprising: a single continuous shaft including, a sheath, an articulation section attached to a distal end of said sheath and, a distal tip attached to a distal end of said articulation section, and two or more separate optical channels that produce two or more distinct views, each of said optical channels comprising an objective lens, located at a distal end of said respective optical channel and a means of capturing and/or viewing the image; wherein the objective lens of the separate optical channel, which produces the first of said distinct views is located at a first location, said first location located on said distal tip, and the objective lens of the optical channel, which produces the second of said distinct views is located at a second location, said second location located either on a proximal end of said articulation section or on the sheath of said endoscope; wherein the distance between said first location and said second location, measured along the longitudinal axis of said endoscope, is fixed.
Claim 3
Dependent Claim
47 words
An endoscope according to claim 1 , in which each of the distinct multiple views is selected from the group comprising: a monocular view, produced by a single optical channel; a binocular view, produced by two optical channels; and a stereoscopic view, produced by two optical channels.
Claim 4
Dependent Claim
40 words
An endoscope according to claim 1 , in which the components of the optical channels and a display apparatus are chosen such that said endoscope can operate in either the visible, ultraviolet, infrared, or x-ray portions of the electromagnetic spectrum.
Claim 5
Dependent Claim
31 words
An endoscope according to claim 1 , in which the objective lens has a focal length selected from the group comprising: fixed focal length, multiple focal lengths, or variable focal lengths.
Claim 6
Dependent Claim
33 words
An endoscope according to claim 1 , in which each of the distinct views is at an angle of between 0 and 180 degrees with respect to the mechanical axis of said endoscope.
Claim 7
Dependent Claim
30 words
An endoscope according to claim 1 , in which the field of view of each of the optical channels has an angular view of up to 180 degrees or more.
Claim 8
Dependent Claim
46 words
An endoscope according to claim 1 , further comprising a stapling device, said stapling device comprising a staple-firing portion and an anvil portion, wherein one of said portions is located at the first location and the second of said portions is located at the second location.
Claim 9
Dependent Claim
54 words
An endoscope according to claim 1 , wherein the means for capturing or viewing the image comprise one or more of the following elements: (a) an optical relay system; (b) an ocular; and (c) a coupling lens suitable to deliver the image acquired by the objective lens to an image sensor and display apparatus.
Claim 10
Dependent Claim
34 words
An endoscope according to claim 8 , in which the ocular and the coupling lens have a focal length selected from the group comprising: fixed focal length, multiple focal lengths, or variable focal lengths.
Claim 11
Dependent Claim
32 words
An endoscope according to claim 8 comprising an image sensor and a display apparatus, wherein at least two of the two or more distinct views are displayed simultaneously on the display apparatus.
Claim 12
Dependent Claim
19 words
An endoscope according to claim 1 , in which the field of view of the optical channels is circular.
Claim 13
Dependent Claim
19 words
An endoscope according to claim 1 , in which the field of view of the optical channels is rectangular.
