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
An endoscope as claimed in any of the preceding claims, wherein the surface of the conical prism or the spheroidal or conical recess ground into the distal surface of the glass element is given a specular finish.
