Abstract
An endoscope includes a hollow handle housing and an insertion tube including a tip part at the distal end of the endoscope. The tip part includes an illumination arrangement with an elongated single-piece light guide having a proximal light guide end and at least one distal light guide end, wherein the proximal light guide end is adapted for receiving at least one light fiber. The at least one distal light guide end has an end surface adapted for emitting the light from a light source. The cross-section of the proximal light guide end differs from the cross-section of the at least another part of the light guide.
Claims22
An endoscope comprising:
- a handle comprising a hollow handle housing;
- and
- an insertion tube extending from the handle towards a distal end of the endoscope, the insertion tube having a tip part at the distal end of the endoscope, said tip part comprising an illumination arrangement adapted for emitting light emanating from a light source,
- wherein said illumination arrangement comprises an elongated single-piece light guide including a proximal light guide end having a central axial bore and a cross-section, the elongated single-piece light guide also including at least one distal light guide end having a cross-section, wherein the central axial bore of the proximal light guide end is adapted for receiving at least one light fiber and the at least one distal light guide end has an end surface adapted for emitting the light received through the central axial bore from the light source, and
- wherein the cross-section of the proximal light guide end differs from a cross-section of at least one other part of the light guide.
An illumination arrangement for an endoscope having a handle and an insertion tube extending from the handle, the illumination arrangement comprising:
- a single-piece light guide including a proximal light guide end and two prongs extending from the proximal light guide end, the two prongs having end surfaces at distal ends of the prongs, the proximal light guide end having a central axial bore;
- and
- a light fiber coupled end-to-end with the proximal light guide end and received within the central axial bore, the proximal light guide end receiving light from the light fiber through the central axial bore and the end surfaces emitting the light distally of the end surfaces, wherein a cross-section of the proximal light guide end differs from a cross-section of at least one other part of the light guide.
An endoscope comprising:
- a handle;
- an insertion tube extending from the handle;
- a single-piece light guide including a proximal light guide end and two prongs extending from the proximal light guide end, the two prongs having end surfaces at distal ends of the prongs, the proximal light guide end having a central axial bore;
- and
- a light fiber coupled end-to-end with the proximal light guide end and received within the central axial bore, the proximal light guide end receiving light from the light fiber through the central axial bore and the end surfaces emitting the light distally of the end surfaces, wherein a cross-section of the proximal light guide end differs from a cross section of at least one other part of the light guide.
