Abstract
Abstract A pair of forceps has a shank (6) and a pair of resilient arms (2 and 4). A groove (14,16) running along the inner face of each arm (2,4) and communicating with a channel (18) in the shank, accommodates a fibre optic cable which provides illumination at the tip of the forceps for items handled by the forceps. The use of such forceps is particularly suitable for manipulating an artificial lens in a human eye because the surface of the lens is illuminated to make it stand out against the liquid of the eye which has substantially the same refractive index as the lens.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
66 words
A pair of forceps having a shank, and a pair of resilient arms extending from the shank, characterised by a light conducting path extending from the shank to the free end portion of at least one arm, whereby when light is coupled to the path at the shank any item handled by the forceps is illuminated by light emerging from the path at said free end.
Claim 2
Dependent Claim
66 words
A pair of forceps having a shank, and a pair of resilient arms extending from the shank, characterised by a light conducting path extending from the shank to the free end portion of at least one arm, whereby when light is coupled to the path at the shank any item handled by the forceps is illuminated by light emerging from the path at said free end.
Claim 3
Dependent Claim
19 words
Forceps according to Claim 1 characterised in that the light conducting path is provided by an optical fibre cable.
Claim 4
Dependent Claim
39 words
Forceps according to Claim 2 characterised in that the inner face of at least one arm is provided with a groove, and the shank is provided with a channel, the groove and the channel accommodating the fibre optic cable.
Claim 5
Dependent Claim
38 words
Forceps according to Claim 2 or to Claim 3 characterised in that the terminating end of the cable at the free end portion of the arm is provided with an irregular surface to scatter the light emerging therefrom.
Claim 6
Dependent Claim
38 words
Forceps according to any one of Claims 1 to 3 characterised in that the tip portion of each arm comprises a transparent material rigid with the remainder of the arm and is optically coupled to said light path.
Claim 7
Dependent Claim
23 words
Forceps according to Claim 5 characterised in that each tip portion is provided with an irregular surface to scatter the light emerging therefrom.
Claim 8
Dependent Claim
93 words
A pair of surgical forceps having a shank and a pair of resilient arms extending from the shank characterised in that each arm carries a translucent tip portion at each free end thereof, each tip portion having an irregular working surface, and further characterised by an optical conductor extending from an optical coupler mounted on the shank along a passage through the shank to at least one tip portion through a groove in the arm supporting the tip portion whereby to illuminate any member with which the tip portion is brought into contact.
Claim 9
Dependent Claim
93 words
A pair of surgical forceps having a shank and a pair of resilient arms extending from the shank characterised in that each arm carries a translucent tip portion at each free end thereof, each tip portion having an irregular working surface, and further characterised by an optical conductor extending from an optical coupler mounted on the shank along a passage through the shank to at least one tip portion through a groove in the arm supporting the tip portion whereby to illuminate any member with which the tip portion is brought into contact.
