Abstract
Abstract A surgical tool comprises a slidable member having a passage therethrough such as a substantially cylindrical hollow tube. The distal end of the slidable member serves as a first jaw component. An elongated member is positioned in the passage and has a second jaw component on its distal end adapted to oppose the first jaw component. A handle is connected to the slidable member for sliding the same over the elongated member to change the spacing between the first and second jaw components and to apply force to the object held between the jaw components.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
117 words
A surgical tool comprising: an elongated slidable barrel having a hollow passageway therethrough and having an outwardly facing cutting section on its distal end; an elongated shaft positioned in said passageway and having an inwardly facing cutting section on its distal end, said inwardly facing cutting section projecting beyond said distal end of said barrel, said cutting sections adapted to oppose each other in jaw-like fashion; and means for sliding said barrel over said shaft to change the spacing between said respective jaw-like cutting sections and to apply force to the object held between the same, said outwardly facing cutting section being formed on an insert, said insert being attached to said distal end of said barrel.
Claim 2
Dependent Claim
117 words
A surgical tool comprising: an elongated slidable barrel having a hollow passageway therethrough and having an outwardly facing cutting section on its distal end; an elongated shaft positioned in said passageway and having an inwardly facing cutting section on its distal end, said inwardly facing cutting section projecting beyond said distal end of said barrel, said cutting sections adapted to oppose each other in jaw-like fashion; and means for sliding said barrel over said shaft to change the spacing between said respective jaw-like cutting sections and to apply force to the object held between the same, said outwardly facing cutting section being formed on an insert, said insert being attached to said distal end of said barrel.
Claim 3
Dependent Claim
133 words
A surgical tool comprising: an elongated slidable, substantially cylindrically shaped barrel having a hollow passageway therethrough and including an insert attached to its distal end, said insert having an outwardly facing cutting edge thereon; an elongated shaft positioned in said passageway and having its distal end upturned beyond the distal end of said barrel, said upturned end having a cutting edge formed on its inside face so that said respective cutting edges oppose each other in jaw-like fashion; a first handle movably connected to said barrel and a second handle fixedly connected to said shaft, said first handle being pivotally connected to said second handle so that squeezing of said handles toward each other decreases the spacing between said respective jaw-like cutting edges and applies force to the object held between the same.
Claim 4
Dependent Claim
133 words
A surgical tool comprising: an elongated slidable, substantially cylindrically shaped barrel having a hollow passageway therethrough and including an insert attached to its distal end, said insert having an outwardly facing cutting edge thereon; an elongated shaft positioned in said passageway and having its distal end upturned beyond the distal end of said barrel, said upturned end having a cutting edge formed on its inside face so that said respective cutting edges oppose each other in jaw-like fashion; a first handle movably connected to said barrel and a second handle fixedly connected to said shaft, said first handle being pivotally connected to said second handle so that squeezing of said handles toward each other decreases the spacing between said respective jaw-like cutting edges and applies force to the object held between the same.
Claim 5
Dependent Claim
24 words
A surgical tool as defined in claim 2 wherein said cutting edges form an angle with respect to the longitudinal axis of said barrel.
Claim 6
Dependent Claim
32 words
A surgical tool as defined in claim 2 which further includes spring means between said handles so that said handles are returnable to their static positions when a gripping force is released.
