Abstract

Abstract A vascular clamp and forceps systems. The clamp has a pair of clamping blades which are spring-loaded closed, and the forceps has a pair of jaws which are also spring-loaded closed. Forcepsengaging means is connected to the blades, and clamp-engaging means is carried by the jaws. When the jaws are forced apart and then relaxed onto the clamp, the clamping blades are spread apart to receive the tissue to be clamped upon, and when the handles of the forceps are pressed together against their spring-load, the forceps is released from the clamp, and the clamp is left installed in place. The said means may be provided with multiposition arrangements whereby there is made possible a plurality of stable angular relationships between the clamp and the forceps.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 374 words
In combination: a vascular clamp comprising a pair of arms, a pivot joining said arms together for pivotal movement toward and away from one another, spring means in opposition to both of said arms biasing them apart, a clamping blade carried by each arm on the same side of the pivot as its respective arm, said clamping blades being so disposed and arranged relative to their respective arms and to each other that they tend to approach each other as the arms are spread apart, and to move apart from one another when the arms are moved toward one another, each clamping blade having a bearing surface, said bearing surfaces facing one another whereby to bear upon tissue held between the blades and to clamp onto said tissue as a consequence of the bias of the spring means when the arms are released, and forceps-engaging means on each of said arms to engage the jaws of a forceps whereby the arms may be pressed together by said forceps; and forceps for engaging said clamp and spreading the clamping blades apart by pressing said arms together, comprising a pair of jaws, a pivot joining said jaws together for a pivotal movement toward and away from one another, a handle attached to each jaw and extending on the opposite side of the pivot from its respective jaw, said jaws being so disposed and arranged relative to their respective handles and to each other that they tend to approach each other as the handles are spread apart, and to move apart from one another when the handles are moved toward each other, clamp-engaging means on each jaw removably engaged to the forceps-engaging means on the clamp, and springing means engaged to the handles biasing said handles apart, whereby with the clamp-engaging means engaged to the forceps-engaging means, the handles released, the springing means of the forceps will cause the jaws to move toward each other, compressing the spring means of the clamp, moving the arms together and the clamping blades apart, and whereby forcing the handles toward one another so as to compress the springing means, spreads the jaws apart, and enables the spring means to move the arms apart and the clamping blades toward one another.
Claim 2
Dependent Claim 374 words
In combination: a vascular clamp comprising a pair of arms, a pivot joining said arms together for pivotal movement toward and away from one another, spring means in opposition to both of said arms biasing them apart, a clamping blade carried by each arm on the same side of the pivot as its respective arm, said clamping blades being so disposed and arranged relative to their respective arms and to each other that they tend to approach each other as the arms are spread apart, and to move apart from one another when the arms are moved toward one another, each clamping blade having a bearing surface, said bearing surfaces facing one another whereby to bear upon tissue held between the blades and to clamp onto said tissue as a consequence of the bias of the spring means when the arms are released, and forceps-engaging means on each of said arms to engage the jaws of a forceps whereby the arms may be pressed together by said forceps; and forceps for engaging said clamp and spreading the clamping blades apart by pressing said arms together, comprising a pair of jaws, a pivot joining said jaws together for a pivotal movement toward and away from one another, a handle attached to each jaw and extending on the opposite side of the pivot from its respective jaw, said jaws being so disposed and arranged relative to their respective handles and to each other that they tend to approach each other as the handles are spread apart, and to move apart from one another when the handles are moved toward each other, clamp-engaging means on each jaw removably engaged to the forceps-engaging means on the clamp, and springing means engaged to the handles biasing said handles apart, whereby with the clamp-engaging means engaged to the forceps-engaging means, the handles released, the springing means of the forceps will cause the jaws to move toward each other, compressing the spring means of the clamp, moving the arms together and the clamping blades apart, and whereby forcing the handles toward one another so as to compress the springing means, spreads the jaws apart, and enables the spring means to move the arms apart and the clamping blades toward one another.
Claim 3
Dependent Claim 77 words
A combination according to claim 1 in which each bearing surface has a substantial dimension of axial length extending in a direction away from the pivot, and of width extending laterally relative to the dimension of length, there being a substantially smooth area extending axially adjacent to both axially extending edges of the bearing surfaces, and between said smooth areas a plurality of declivities to receive and retain tissue when the bearing surfaces bear against said tissue.
Claim 4
Dependent Claim 28 words
A combination according to claim 1 in which one of said means is an opening, and the other is a projection to enter and engage in the opening.
Claim 5
Dependent Claim 41 words
A combination according to claim 3 in which the wall of the opening and the outer surface of the projection each has a plurality of discontinuities, whereby the said means can stably engage each other at a plurality of angular alignments.
Claim 6
Dependent Claim 27 words
A combination according to claim 4 in which the number of discontinuities in the wall of the opening is greater than the number carried by the projection.
Claim 7
Dependent Claim 36 words
A combination according to claim 4 in which the projection is a four-sided, square-based pyramid, and in which the number of discontinuities in the wall of the opening is a multiple of four greater than one.
Claim 8
Dependent Claim 77 words
A combination according to claim 3 in which each bearing surface has a substantial dimension of axial length extending in a direction away from the pivot, and of width extending laterally relative to the dimension of length, there being a substantially smooth area extending axially adjacent to both axially extending edges of the bearing surfaces, and between said smooth areas a plurality of declivities to receive and retain tissue when the bearing surfaces bear against said tissue.
Claim 9
Dependent Claim 77 words
A combination according to claim 6 in which each bearing surface has a substantial dimension of axial length extending in a direction away from the pivot, and of width extending laterally relative to the dimension of length, there being a substantially smooth area extending axially adjacent to both axially extending edges of the bearing surfaces, and between said smooth areas a plurality of declivities to receive and retain tissue when the bearing surfaces bear against said tissue.
Claim 10
Dependent Claim 162 words
A vascular clamp comprising a pair of arms, a pivot joining said arms together for pivotal movement toward and away from one another, spring means in opposition to both of said arms biasing them apart, a clamping blade carried by each arm on the same side of the pivot as the arm, said clamping blades being so disposed and arranged relative to their respective arms and to each other that they tend to approach each other as the arms are spread apart, and to move apart from one another when the arms are moved toward one another, each clamping blade having a bearing surface, said bearing surfaces facing one another whereby to bear upon tissue held between the blades and to clamp onto said tissue as a consequence of the bias of the spring means when the arms are released; a joggle connecting each arm to its respective blade, whereby the blades are crossed over one another with respect to said arms.
