Abstract
Abstract A plurality of instruments or members are provided to plastically deform spine plates or rods to a configuration which corresponds to a desired configuration for connection with a spinal column. A pair of flat benders have slots which are engageable with a spine plate to bend and/or twist the spine plate. A pair of tube benders are engageable with a rod to bend the rod. One of the flat benders may be used with one of the tube benders to form a bend in the rod. In addition, the two flat benders may be used together to bend the rod. These instruments make possible two dimensional bending of spine plates and three dimensional bending of spine rods.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
543 words
An apparatus for use in bending rods and plates to be connected to a spinal column, said apparatus comprising a first longitudinally extending flat bender, said first flat bender having first and second parallel major side surfaces and a first end portion with first surface means for defining a first elongated slot extending through said first flat bender between said first and second major side surfaces to receive a first portion of a plate, said first elongated slot having a longitudinal central axis extending perpendicular to a longitudinal central axis of said first flat bender, said first surface means including a first end surface defining a first end portion of said first elongated slot, a second end surface defining a second end portion of said first elongated slot, and a pair of parallel side surfaces extending between said first and second end portions of said first elongated slot, said first flat bender having a second end portion with second surface means for defining a first circular opening extending through said first flat bender between said first and second major side surfaces to receive a first portion of a rod, said first circular opening having a central axis which intersects and extends perpendicular to a longitudinal central axis of said first flat bender, a second longitudinally extending flat bender, said second flat bender having third and fourth parallel major side surfaces and a first end portion with third surface means for defining a first elongated slot extending through said second flat bender between said third and fourth major side surfaces to receive a second portion of a plate having a first portion received by the first elongated slot in said first flat bender, said second elongated slot having a longitudinal central axis extending perpendicular to a longitudinal central axis of said second flat bender, said third surface means including a first end surface defining a first end portion of said first elongated slot in said second flat bender, a second end surface defining a second end portion of said first elongated slot in said second flat bender, and a pair of parallel side surfaces extending between said first and second end portions of said first elongated slot in said second flat bender, said second flat bender having a second end portion with fourth surface means for defining a first circular opening extending through said second flat bender between said third and fourth major side surfaces to receive a second portion of a rod having a first portion received by an opening in said first flat bender, said first circular opening in said second flat bender having a central axis which intersects and extends perpendicular to a longitudinal central axis of said second flat bender, said first and second flat benders being movable relative to each other under the influence of force manually applied to end portions of said first and second flat benders to plastically deform a plate extending through the first slots in said fist and second flat benders, said first and second flat benders being movable relative to each other under the influence of force manually applied to end portions of said first and second flat benders to plastically deform a rod extending through openings in said first and second flat benders.
Claim 2
Independent Claim
543 words
An apparatus for use in bending rods and plates to be connected to a spinal column, said apparatus comprising a first longitudinally extending flat bender, said first flat bender having first and second parallel major side surfaces and a first end portion with first surface means for defining a first elongated slot extending through said first flat bender between said first and second major side surfaces to receive a first portion of a plate, said first elongated slot having a longitudinal central axis extending perpendicular to a longitudinal central axis of said first flat bender, said first surface means including a first end surface defining a first end portion of said first elongated slot, a second end surface defining a second end portion of said first elongated slot, and a pair of parallel side surfaces extending between said first and second end portions of said first elongated slot, said first flat bender having a second end portion with second surface means for defining a first circular opening extending through said first flat bender between said first and second major side surfaces to receive a first portion of a rod, said first circular opening having a central axis which intersects and extends perpendicular to a longitudinal central axis of said first flat bender, a second longitudinally extending flat bender, said second flat bender having third and fourth parallel major side surfaces and a first end portion with third surface means for defining a first elongated slot extending through said second flat bender between said third and fourth major side surfaces to receive a second portion of a plate having a first portion received by the first elongated slot in said first flat bender, said second elongated slot having a longitudinal central axis extending perpendicular to a longitudinal central axis of said second flat bender, said third surface means including a first end surface defining a first end portion of said first elongated slot in said second flat bender, a second end surface defining a second end portion of said first elongated slot in said second flat bender, and a pair of parallel side surfaces extending between said first and second end portions of said first elongated slot in said second flat bender, said second flat bender having a second end portion with fourth surface means for defining a first circular opening extending through said second flat bender between said third and fourth major side surfaces to receive a second portion of a rod having a first portion received by an opening in said first flat bender, said first circular opening in said second flat bender having a central axis which intersects and extends perpendicular to a longitudinal central axis of said second flat bender, said first and second flat benders being movable relative to each other under the influence of force manually applied to end portions of said first and second flat benders to plastically deform a plate extending through the first slots in said fist and second flat benders, said first and second flat benders being movable relative to each other under the influence of force manually applied to end portions of said first and second flat benders to plastically deform a rod extending through openings in said first and second flat benders.
Claim 3
Dependent Claim
123 words
An apparatus as set forth in claim 1 wherein said first slot in said first flat bender is spaced from said first circular opening in said first flat bender by a distance which is at least ten times the length of said first slot in said first flat bender and said fist slot in said second flat bender is spaced from said first circular opening in said second flat bender by a distance which is at least ten times the length of said first slot in said second flat bender to provide leverage for the force manually applied to end portions of said first and second flat benders during the plastic deformation of a plate and during the plastic deformation of a rod.
