First Claim
Patent Images
1. An endoscope comprising:
- an elongated shaft, said elongated shaft having a distal end terminating in a distal end surface, a proximal end, an outer side wall extending from said distal end to said proximal end, and at least one internal passageway extending from said distal end to said proximal end;
a multiplicity of image capturing means being disposed on one or both of said outer side wall and said distal end surface so as to face outwardly therefrom in spaced relationship to one another, each of said image capturing means comprising lens means for defining an outwardly facing field of view for that image capturing means, and each of said image capturing means being adapted to capture an image of any object located within said field of view and to convert that image into corresponding signals, with said image capturing means being arranged so that each of said multiplicity of image capturing means has a substantially different field of view, at least one of said image capturing means being disposed adjacent to first and second of the other of said image capturing means and disposed therebetween, and disposed adjacent to third and fourth of other of said image capturing means and disposed therebetween;
processing means associated with said proximal end of said shaft, said processing means being adapted to receive said corresponding signals from said image capturing means and to generate display comprising one or more of said images at said proximal end of said shaft; and
a multiplicity of connecting means for connecting each of said image capturing means to said processing means.

Abstract
A multiple view endoscope for providing "on command" images of a plurality of different fields of view surrounding the distal end of the endoscope without having to move the endoscope from an initially established position in order to access the different fields of view. A multiplicity of image capturing means are disposed in an array on the distal end to permit the operator to select and view either any one of, or any combination of, the multiple views provided by the multiplicity of image capturing means.

15. A method for selectively viewing one or more images of objects located at a remote site, said method comprising the steps of:
-
(a) providing an endoscope comprising; an elongated shaft, said elongated shaft having a distal end, a proximal end, an outer side wall extending from said distal end to said proximal end, and at least one internal passageway extending from said distal end to said proximal end; a multiplicity of image capturing means being disposed on one or both of said outer side wall and said distal end so as to face outwardly therefrom in spaced relationship to one another, each of said image capturing means comprising lens means for defining an outwardly facing field of view for that image capturing means, and each of said image capturing means being adapted to capture an image of any objects located within said field of view and to convert that image into corresponding signals, with said image capturing means being arranged so that a multiplicity of said image capturing means have substantially different fields of view, each of said image capturing means being disposed adjacent to and between first and second of other of said image capturing means and disposed adjacent to and between third and fourth of other of said image capturing means; processing means associated with said proximal end of said shaft, said processing means being adapted to receive said corresponding signals from said image capturing means and to generate a display comprising one or more of said images at said proximal end of said shaft; and a multiplicity of connecting means for connecting each of said image capturing means to said processing means; (b) positioning said distal end of said shaft at said remote site so that said distal end of said shaft lies substantially adjacent to an object located at said remote site; and (c) operating said processing means so as to generate a plurality of different displays comprising one or more of said images without further movement of said endoscope.
