Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
142 words
A surgical tool comprising: a. a first elongated member having a cutting edge; b. a second elongated member pivotally connected to said first member intermediate the ends of both, said second member having a flat surface and a cutting edge, said cutting edge cooperating with the cutting edge on Said first member to produce a continuous shearing action on a piece of tissue interposed between them, said shearing action occurring at a point that advances from the pivotal connection towards an end as one of said members is pivotally moved towards the other of said members; and c. means mounted on said first member in contact with said flat surface of said second member for progressively and continuously crushing between said first and second members the capillaries of said piece of tissue being sheared just prior to said continuously advancing shear point.
Claim 2
Dependent Claim
142 words
A surgical tool comprising: a. a first elongated member having a cutting edge; b. a second elongated member pivotally connected to said first member intermediate the ends of both, said second member having a flat surface and a cutting edge, said cutting edge cooperating with the cutting edge on Said first member to produce a continuous shearing action on a piece of tissue interposed between them, said shearing action occurring at a point that advances from the pivotal connection towards an end as one of said members is pivotally moved towards the other of said members; and c. means mounted on said first member in contact with said flat surface of said second member for progressively and continuously crushing between said first and second members the capillaries of said piece of tissue being sheared just prior to said continuously advancing shear point.
Claim 3
Dependent Claim
34 words
The subject matter of claim 1 wherein the means mounted on said first elongated member comprises an arcuate element pivotally mounted and positioned to roll on the flat edge of the second elongated member.
Claim 4
Dependent Claim
32 words
The subject matter of claim 2 wherein a biasing means consisting of a spring element is connected between a connection point on the first member and a point on the arcuate element.
Claim 5
Dependent Claim
58 words
The structure of claim 3 wherein the arcuate element has a notch formed therein adjacent a point pivotally connecting the arcuate element to the first member, the notch receiving one end of the spring element, the opposite end of the spring element abutting the connection point which constitutes a fixed projection for causing flexing of the spring element.
Claim 6
Dependent Claim
85 words
The subject matter of claim 1 wherein the means mounted on said first elongated member is a flexibly yieldable arcuate element having a first end portion positioned to roll on the flat of the second elongated member, the biasing means comprising: an intermediate portion coiled around a fixed point on the first elongated member; and a second end portion abutting a second fixed point on the first elongated member in a manner biasing the first end portion against the flat of the second elongated member.
Claim 7
Dependent Claim
60 words
The structure of claim 1 wherein the means mounted on said first elongated member comprises a roller having an axial support mounted in a track formed in said first elongated member, whereby the axial support moves in the track as the shearing action proceeds, thus resulting in maintained contact between the roller and the flat on the second elongated member.
