Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
94 words
An apparatus for placing adjacent bone ends under end to end compression comprising in combination a staple having spaced apart prongs adapted to be forced into adjacent bone ends, said prongs connected by a head member having at least two spaced apart transverse ribs, drive means engaging said ribs to hold the staple during insertion of the prongs into the bone ends to be compressed and means on said drive means forcing said ribs toward one another after said staple is in place so as to urge the prongs together and toe them in.
Claim 2
Independent Claim
94 words
An apparatus for placing adjacent bone ends under end to end compression comprising in combination a staple having spaced apart prongs adapted to be forced into adjacent bone ends, said prongs connected by a head member having at least two spaced apart transverse ribs, drive means engaging said ribs to hold the staple during insertion of the prongs into the bone ends to be compressed and means on said drive means forcing said ribs toward one another after said staple is in place so as to urge the prongs together and toe them in.
Claim 3
Dependent Claim
56 words
An apparatus as claimed in claim 1 wherein the drive means is a pair of scissor legs pivoted together intermediate their ends, gripping means at one end of said legs engaging said ribs and link means at the other end of said legs acting on said legs to cause them to pivot relatively to one another.
Claim 4
Dependent Claim
38 words
An apparatus as claimed in claim 2 wherein the gripping means includes a notched portion on the said one end of said legs engaging the ribs on the head member and removable finger members engaged beneath the ribs.
Claim 5
Dependent Claim
35 words
An apparatus as claimed in claim 2 wherein the link means are connected to a screw operator moving said links toward and away from the scissor leg ends to cause the scissor legs to pivot.
Claim 6
Dependent Claim
65 words
A tool for crimping staples having spaced prongs connected by a header member having spaced apart collapsible ribs comprising a pair of scissor legs pivoted together intermediate their ends, gripping means at one end of said legs engaging said collapsible ribs and link means at the other end of said scissor legs acting on said legs to cause them to pivot relative to one another.
Claim 7
Dependent Claim
65 words
A tool for crimping staples having spaced prongs connected by a header member having spaced apart collapsible ribs comprising a pair of scissor legs pivoted together intermediate their ends, gripping means at one end of said legs engaging said collapsible ribs and link means at the other end of said scissor legs acting on said legs to cause them to pivot relative to one another.
Claim 8
Dependent Claim
38 words
A tool as claimed in claim 5 wherein the gripping means includes a notched portion on the said one end of said legs engaging the ribs on the head member and removable finger members engaged beneath the ribs.
Claim 9
Dependent Claim
35 words
A tool as claimed in claim 5 wherein the link means are connected to a screw operator moving said links toward and away from the scissor leg ends to cause the scissor legs to pivot.
Claim 10
Independent Claim
57 words
The method of connecting and compressing bone ends together comprising the steps of: a. inserting the spaced prongs of a two pronged staple having a head member with a collapsible rib connecting said prongs; and b. collapsing said rib sides toward one another to cause the prongs to move toward one another and compress the bone ends.
Claim 11
