Estimating the term…
The present invention provides an endoscopic sheath for protecting and/or changing an angle of view of an endoscope. The sheath has a distal portion configured to engage a distalmost portion of an endoscope imaging optics. The distal portion houses structure for changing the angle of view of an endoscope. In a preferred embodiment, this structure includes a prism. The distal portion may additionally house structure for changing the angle of illumination of an illumination portion of an endoscope. This structure may be a prism or a curved light guide or at least one angled optical fiber. Both the structure for changing the angle of view of an endoscope and the optical member for changing the angle of illumination of an endoscope may be positioned within the distal portion to align with the respective imaging or illumination elements of the endoscope.
An attachment for changing the angle of view of an endoscope, the endoscope including a proximal end and a distal end and having an imaging portion and an illumination portion, the imaging and illumination portions each having a defined angle of view, the attachment comprising:
An attachment for changing the angle of view of an endoscope, the endoscope including a proximal end and a distal end and having an imaging portion and an illumination portion, the imaging and illumination portions each having a defined angle of view, the attachment comprising:
An attachment for changing the angle of view of an endoscope, the endoscope including a proximal end and a distal end and having an imaging portion and an illumination portion, the imaging and illumination portions each having a defined angle of view, the attachment comprising:
In combination with an endoscope including proximal and distal end portions and having imaging optics with a defined angle of view and illumination optics with a defined angle of illumination, an endoscope attachment for changing the angle of view and for changing the angle of illumination of the endoscope, the endoscope attachment configured to be positioned adjacent the distal end portion of the endoscope, the endoscope attachment including a support member having a prism mount associated with a distal portion thereof, the prism mount including a prism in general alignment with the imaging optics of the endoscope for providing an inclined angle of view and an optical arrangement independent of the illumination optics of the endoscope for conveying illuminating light in a distal direction to the distal portion of the support member and for directing the illuminating light into the inclined angle of view.
