Abstract
An endoscope attachment enables an endoscope to capture images of areas in front and at the sides of the endoscope. The endoscope attachment has a transparent attaching part which is used to attach the endoscope attachment to a probe of the endoscope and has two through-holes. A cylindrical transparent image capturing part is used to enable a camera of the probe to capture images and has a trumpet-shaped second mirror on the outer wall of the image capturing part and a wide angle lens with a hyperboloid in the image capturing part. A first mirror is formed at a part of the hyperboloid of the wide angle lens.
Claims8
An endoscope attachment which is attachable to a distal end of a probe of an endoscope used to image a digestive organ, the endoscope attachment comprising:
- a view field obtaining part operable to obtain a front view field and a side view field for the probe;
- and
- a convex-shaped illumination light providing part operable to diffuse illumination light illuminating an area in front of the probe in order to provide the illumination light to an area at a side of the endoscope attachment,
- wherein the view field obtaining part is a mirror having an opening,
- an image of an area at a side of the probe is captured by a camera of the probe via the mirror,
- an image of an area in front of the probe is captured by the camera through the opening of the mirror, and
- the convex-shaped illumination light providing part is a ring-shaped mirror which is used as the view field obtaining part.
