Abstract
Abstract A plurality of the elongated grippers are mounted in spaced apart, axially parallel, relation to project perpendicularly from opposing, substantially semi-circular, jaws of a pair of blades pivoted at a midportion thereof in scissor-fashion. A pair of lever arms are pivotally connected at one end and have handle portions formed at opposite ends thereof, said blades being symmetrically mounted between said lever arms with one end of each of the blades opposite said jaws pivotally attached to one of the lever arms for actuation thereby and for providing a mechanical advantage to close the jaws on application of a manual force applied to the handle portions. This closing brings the grippers of each jaw toward each other providing a compressive force on a breast requiring closed compression rupture when positioned therebetween.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
223 words
A manually operated compressor for achieving the initial rupturing "pop" in performing the closed compression technique to alleviate a contracted fibrous capsule condition of an augmentation mammaplasty implant comprising a pair of actuating lever arms pivotally interconnected at one end thereof and disposed in angular relation and having opposite free ends adapted as handles for gripping and operating the compressor, a pincers mounted on and between said lever arms for actuation thereby, said pincers comprising a pair of centrally pivoted blades each having a semi-circular shaped jaw, and a plurality of elongated grippers mounted on each of said jaws to project perpendicularly from a rear, breast facing, side of the jaws and arranged in parallel spaced relation, said jaws and grippers defining a substantially circular opening sized to circumferentially fit the base of the implant of a patient's breast when the jaws are in open position, the rear facing jaw having the grippers spaced along the length thereof, the other, front facing, jaw having the grippers spaced along substantially half the length of the jaw adjacent the central pivot of the pincers to permit closing of the jaws to reduce the area of said opening enabling circumferential compressive force to be exerted on the patient's breast at the base of the implant when the breast is positioned within the confines of the grippers.
Claim 2
Dependent Claim
223 words
A manually operated compressor for achieving the initial rupturing "pop" in performing the closed compression technique to alleviate a contracted fibrous capsule condition of an augmentation mammaplasty implant comprising a pair of actuating lever arms pivotally interconnected at one end thereof and disposed in angular relation and having opposite free ends adapted as handles for gripping and operating the compressor, a pincers mounted on and between said lever arms for actuation thereby, said pincers comprising a pair of centrally pivoted blades each having a semi-circular shaped jaw, and a plurality of elongated grippers mounted on each of said jaws to project perpendicularly from a rear, breast facing, side of the jaws and arranged in parallel spaced relation, said jaws and grippers defining a substantially circular opening sized to circumferentially fit the base of the implant of a patient's breast when the jaws are in open position, the rear facing jaw having the grippers spaced along the length thereof, the other, front facing, jaw having the grippers spaced along substantially half the length of the jaw adjacent the central pivot of the pincers to permit closing of the jaws to reduce the area of said opening enabling circumferential compressive force to be exerted on the patient's breast at the base of the implant when the breast is positioned within the confines of the grippers.
Claim 3
Dependent Claim
49 words
The manually operated compressor defined in claim 1 in which said actuating lever arms and pincers are constructed and arranged to provide a mechanical advantage to the closing of said jaws and grippers when manual force is applied to said handles to reduce the angle between said lever arms.
Claim 4
Dependent Claim
101 words
The manually operated compressor defined in claim 2 in which each of said pivoted blades has an actuating section opposite said jaw, each actuating section being pivoted at an end thereof to one of said lever arms at a predetermined distance from said lever arm pivotal interconnection as said pincer mounting, the distances measured along said actuating sections between said end pivot and said central pivot and said predetermined distances being substantially of the same order, and the ratio of said predetermined distance to the overall effective length of said lever arm being approximately 1 to 31/2 providing said mechanical advantage.
Claim 5
Dependent Claim
29 words
The manually operated compressor defined in claim 1 in which each of said grippers has a rounded free end, said ends being in substantially coplanar relation with each other.
Claim 6
Dependent Claim
25 words
The manually operated compressor defined in claim 4 in which each of said grippers has a surface of low heat conductivity to avoid cold-to-the-touch discomfort.
Claim 7
Dependent Claim
51 words
The manually operated compressor defined in claim 1 in which each of said actuating lever arms has an end portion including said handle bent laterally away from said pincers to provide clearance therefrom for gripping said handles when said lever arms are brought toward each other to fully close said jaws.
Claim 8
Dependent Claim
33 words
The manually operated compressor defined in claim 6 in which each of said lever arms is formed as a two-piece structure of bar stock interconnected in angular relation to provide said lateral bend.
