Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
78 words
A flexible forceps instrument comprising a cable sheath, a forceps having a scissor mechanism attached to a distal end of said sheath, a manual operating assembly, and an operating cable within said sheath and attached at a distal end to said scissor mechanism and demountably attached at a proximal end to said manual operating assembly, characterised by a connector attached to a proximal end of said cable sheath for demountably attaching the sheath to the manual operating assembly.
Claim 2
Dependent Claim
78 words
A flexible forceps instrument comprising a cable sheath, a forceps having a scissor mechanism attached to a distal end of said sheath, a manual operating assembly, and an operating cable within said sheath and attached at a distal end to said scissor mechanism and demountably attached at a proximal end to said manual operating assembly, characterised by a connector attached to a proximal end of said cable sheath for demountably attaching the sheath to the manual operating assembly.
Claim 3
Dependent Claim
25 words
A flexible forceps instrument as claimed in claim 1 characterised in that the forceps is demountably attached to the distal end of said cable sheath.
Claim 4
Dependent Claim
41 words
A flexible forceps instrument as claimed in claim 2 characterised in that said cable sheath has forceps-attaching means for demountably attaching said forceps to a distal end of said sheath and said forceps has receiving means engaged by said forceps-attaching means.
Claim 5
Dependent Claim
42 words
A flexible forceps instrument as claimed in claim 3 characterised in that said forceps-attaching means includes a resilient member attached to said distal end of said sheath, and said receiving means of the forceps includes a recess for receiving said resilient member.
Claim 6
Dependent Claim
61 words
A flexible forceps instrument as claimed in claim 3 characterised in that said forceps-attaching means includes a collar attached to said distal end of said sheath, said collar having a resilient member, and said receiving means of said forceps includes a forceps pincer supporting body slidably receivable in said collar, said body having a mounting portion for receiving said resilient member.
Claim 7
Dependent Claim
34 words
A flexible forceps instrument as claimed in claim 5 characterised in that said resilient member comprises a finger having a locking tooth and said mounting portion includes a recess for receiving said locking tooth.
Claim 8
Dependent Claim
27 words
A flexible forceps instrument as claimed in claim 6 characterised in that said mounting portion further includes a flat abutment surface for abutting engagement with said finger.
Claim 9
Dependent Claim
59 words
A flexible. forceps Instrument as claimed in any one of claims 1 to 7 characterised in that said connector comprises a hollow tube having a coupling means at one end for demountably coupling said connector to said manual operating assembly and further having a cable sheath attachment portion at another end for attaching said cable sheath to said connector.
Claim 10
Dependent Claim
75 words
A flexible forceps instrument as claimed in any one of claims 1 to 8 characterised in that said manual operating assembly includes a central shaft having a throughbore for receiving said operating cable; a coupling nut rotatably mounted on a distal end of said shaft, said coupling nut adapted to couple with said connector; and a cable slide slidably mounted on said central shaft, said cable slide having means for releasably receiving said operating cable.
Claim 11
Dependent Claim
30 words
A flexible forceps instrument as claimed in claim 9 characterised in that said manual operating assembly further includes a thumb-ring rotatably mounted on a proximal end of said central shaft.
Claim 12
Dependent Claim
56 words
A flexible forceps instrument as set forth in any one of the preceding claims characterised by a cleaning fixture including a hollow tube having an inlet at one end to receive fluid under pressure and having connecting means at another end for demountably connecting said fixture to said connector in place of said manual operating assembly.
