Abstract
Abstract A clamping instrument for use for occluding blood vessels and other fluid ducts in an animal or a human body has a slender tubular shaft provided at one end with a lateral clamping jaw and at its other end with a hand piece. A thin wire is slidably disposed in the shaft and has a lateral clamping jaw at one end disposed in confronting clamping relation with the fixed jaw on the shaft. The wire is slidable through the hand piece and extends rearwardly therefrom with such extension being mounted or attached to the hand piece to prevent turning movement thereof and spring means biasing the movable jaw on the wire into clamping relation with the fixed jaw.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
143 words
A clamping implement, especially suitable for use as a vascular or hemostatic clamp, comprising a tubular shaft having open opposing end portions, one of said end portions defining a fixed clamping jaw angularly related to and extending from the shaft and a hand piece supportively engaging the other end portion, an elongated member slidably housed in the shaft and having opposing end portions, one of said end portions defining a movable clamping jaw and being angularly related to and extending from the member and being disposed in confronting complementary clamping relation with the clamping jaw on the shaft, said other end portion of the member being slidably received by the hand piece and extending therethrough and therebeyond and means structurally associated with said extending portion of the member to continuously urge the movable clamping jaw into claimping relation with the fixed clamping jaw.
Claim 2
Dependent Claim
12 words
The clamping implement of claim 1, wherein said member is a wire.
Claim 3
Dependent Claim
24 words
The clamping implement of claim 2 wherein said means structurally associated with said extending portion of the member is an energy storage spring means.
Claim 4
Dependent Claim
15 words
The clamping implement of claim 3 wherein said spring means is non-integral with said wire.
Claim 5
Dependent Claim
176 words
A clamping implement, especially suitable for use as a vascular or hemostatic clamp, comprising a tubular shaft having open opposing end portions, one of said end portions defining a fixed clamping jaw angularly related to and extending from the shaft and a hand piece supportively engaging the other end portion, an elongated member slidably housed in the shaft and having opposing end portions, one of said end portions defining a movable clamping jaw and being angularly related to and extending from the member and being disposed in confronting complementary clamping relation with the clamping jaw on the shaft, said other end portion of the member being slidably received by the hand piece and extending therethrough and therebeyond and means structurally associated with said extending portion of the member functioning as an energy storage means serving to bias the movable clamping jaw into clamping relation with the fixed clamping jaw, wherein said energy storage means includes a spring means, and wherein said last means includes a spring means formed integrally with the extending portion of the member.
Claim 6
Dependent Claim
176 words
A clamping implement, especially suitable for use as a vascular or hemostatic clamp, comprising a tubular shaft having open opposing end portions, one of said end portions defining a fixed clamping jaw angularly related to and extending from the shaft and a hand piece supportively engaging the other end portion, an elongated member slidably housed in the shaft and having opposing end portions, one of said end portions defining a movable clamping jaw and being angularly related to and extending from the member and being disposed in confronting complementary clamping relation with the clamping jaw on the shaft, said other end portion of the member being slidably received by the hand piece and extending therethrough and therebeyond and means structurally associated with said extending portion of the member functioning as an energy storage means serving to bias the movable clamping jaw into clamping relation with the fixed clamping jaw, wherein said energy storage means includes a spring means, and wherein said last means includes a spring means formed integrally with the extending portion of the member.
Claim 7
Dependent Claim
52 words
The clamping implement of claim 5 wherein said wire has a portion intermediate and connecting the rearwardly extending portion and the spring means which defines a trigger that can be pushed by a finger to move the movable clamping jaw on the wire away from the fixed clamping jaw on the shaft.
Claim 8
Dependent Claim
20 words
The clamping implement of claim 5 wherein said jaws are disposed substantially normal to the coaxially arranged shaft and member.
Claim 9
Dependent Claim
37 words
The claMping implement of claim 5 wherein said fixed jaw is arcuate in cross-section and the movable jaw is round and is of a radius to be seatingly received within the semi-circular confines of the fixed jaw.
Claim 10
Dependent Claim
16 words
The clamping implement of claim 5 wherein said fixed and movable jaws have flat opposed faces.
