Abstract

Abstract An endoscope for 360 DEG observation, has a lens system 1 or an optical fibre system for the image, and a fibre light conductor 4 surrounding the imaging system 1 to illuminate the subject. A cylindrical glass ring 9' for diffusively dispersing the light and surrounding the distal extremity of the optical system 1, 2, 3 is situated beyond the fibre light conductor 4, and, in front of the optical system there is situated a reflector 18 fitted by mounting means 10a on the distal extremity of said optical system or of said light conductor. The reflector is either a conical prism having its apex directed towards the optical system or as shown is a glass element 17 whose distal surface comprises a recess 1 of conical or spheroidal shape, which is ground in symmetrically to the optical axis, and acting as a reflector. <IMAGE>

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 132 words
An endoscope for 360 observation, of the kind comprising a lens system or an imageconductor optical fibre system, incorporating a fibre light conductor surrounding the optical system in the'form of a cylinder wherein a cylindrical glass ring diffusively dispersing the light and surrounding the distal extremity of the optical system is situated beyond the fibre light conductor, and wherein, in front of the optical system is situated a reflector fitted by mounting means on the distal extremity of the optical system or of the light conductor, said reflector being a conical prism having its apex directed towards said optical system, or a spherical or cylindrical glass element whose distal surface comprises a recess of conical or spheroidal shape, which is ground in symmetrically to the optical axis, and acting as a reflector.
Claim 2
Dependent Claim 132 words
An endoscope for 360 observation, of the kind comprising a lens system or an imageconductor optical fibre system, incorporating a fibre light conductor surrounding the optical system in the'form of a cylinder wherein a cylindrical glass ring diffusively dispersing the light and surrounding the distal extremity of the optical system is situated beyond the fibre light conductor, and wherein, in front of the optical system is situated a reflector fitted by mounting means on the distal extremity of the optical system or of the light conductor, said reflector being a conical prism having its apex directed towards said optical system, or a spherical or cylindrical glass element whose distal surface comprises a recess of conical or spheroidal shape, which is ground in symmetrically to the optical axis, and acting as a reflector.
Claim 3
Dependent Claim 43 words
An endoscope as claimed in claim 1, wherein the distal glass element is a spheroidal lens which at its proximal end is firmly joined to a rear lens which is installed in said mounting means pushed over the extremity of the optical system.
Claim 4
Dependent Claim 41 words
An endoscope as claimed in claim 1, wherein the glass element constructed as a cylinder is pushed on and secured with its proximal end in a cylindrical metal ring as a mounting on to the distal extremity of the optical system.
Claim 5
Dependent Claim 22 words
An endoscope as claimed in claim 1, 2 or 3, wherein the distal glass element surface is covered by a shielding means.
Claim 6
Dependent Claim 22 words
An endoscope as claimed in claim 4, wherein the shielding means comprises a shielding plate, a protective lid, or a protective cap.
Claim 7
Dependent Claim 37 words
