Abstract
Abstract A bone clamp for aiding a surgeon in positioning bones and securing them together and having means for properly orientating drills so that aligned holes may be drilled through the two bones, and also having means for locating the screw to be inserted through the bones to hold them together. One member of the clamp includes a generally V-shaped portion which can be inserted under the innermost bone so that the latter can be accurately located with respect to the guide means for positioning the drills and screw.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
167 words
A bone clamp for holding two bones together in proper relationship while drilling said bones and inserting a screw therein, said clamp comprising, a first member having an elongated threaded portion and a generally V-shaped bone holding portion which is offset from said threaded portion, a second member slidably engaged on said first member and having an elongated opening therethrough including a central portion which is alignable with said V-shaped portion, a nut threadably engaged on said threaded portion for forcing said members toward one another so that said first and second members clampingly engage said two bones therebetween with one of said bones being located in said V-shaped portion, and a pair of drill guide members shiftably mounted in said opening and selectively shiftable into said central portion in said opening in alignment with said bones and said V-shaped portion, said guide members each having an aperture for receiving a drill for drilling through said bones, and said V-shaped portion defines a limit of drill travel.
Claim 2
Dependent Claim
167 words
A bone clamp for holding two bones together in proper relationship while drilling said bones and inserting a screw therein, said clamp comprising, a first member having an elongated threaded portion and a generally V-shaped bone holding portion which is offset from said threaded portion, a second member slidably engaged on said first member and having an elongated opening therethrough including a central portion which is alignable with said V-shaped portion, a nut threadably engaged on said threaded portion for forcing said members toward one another so that said first and second members clampingly engage said two bones therebetween with one of said bones being located in said V-shaped portion, and a pair of drill guide members shiftably mounted in said opening and selectively shiftable into said central portion in said opening in alignment with said bones and said V-shaped portion, said guide members each having an aperture for receiving a drill for drilling through said bones, and said V-shaped portion defines a limit of drill travel.
Claim 3
Dependent Claim
63 words
The clamp set forth in claim 1 further characterized in that said guide members can both be shifted in said opening to a position out of said central portion of said opening after performing their drill guiding function, and screw means can be inserted in said central portion of said opening in alignment with the holes formed by said drills in said bones.
Claim 4
Dependent Claim
55 words
The clamp defined in claim 1 further characterized in that said threaded portion of said first member is non-circular in cross section, and said second member has an aperture therethrough for slidably receiving said threaded portion, said aperture being of a complementary shape to said threaded portion to prevent relative rotation between said clamp members.
Claim 5
Dependent Claim
55 words
The clamp defined in claim 2 further characterized in that said threaded portion of said first member is non-circular in cross section, and said second member has an aperture therethrough for slidably receiving said threaded portion, said aperture being of a complementary shape to said threaded portion to prevent relative rotation between said clamp members.
Claim 6
Dependent Claim
190 words
A bone clamp for holding two bones together in proper relationship while drilling said bones and inserting a screw therein, said clamp comprising, a first member having an elongated threaded portion and a generally V-shaped bone locating and holding portion which is offset from said threaded portion, said V-shaped member terminating in a sharp free end, a generally flat second member having an aperture for slidable mounting on the threaded portion of said first member and also having an elongated opening therethrough including a central portion which is alignable with said V-shaped portion, a nut threadably engaged on said threaded portion for forcing said members toward one another to clampingly engage said two bones between said member with one of said bones being located in said V-shaped portion, and a pair of drill guide members shiftably mounted in said opening and selectively shiftable into said central portion in said opening in alignment with said bones and said V-shaped portion, said guide members each having a hole therein for receiving a drill for drilling into said bones, said V-shaped portion acting as a stop for said drill to limit drill travel.
Claim 7
Dependent Claim
190 words
A bone clamp for holding two bones together in proper relationship while drilling said bones and inserting a screw therein, said clamp comprising, a first member having an elongated threaded portion and a generally V-shaped bone locating and holding portion which is offset from said threaded portion, said V-shaped member terminating in a sharp free end, a generally flat second member having an aperture for slidable mounting on the threaded portion of said first member and also having an elongated opening therethrough including a central portion which is alignable with said V-shaped portion, a nut threadably engaged on said threaded portion for forcing said members toward one another to clampingly engage said two bones between said member with one of said bones being located in said V-shaped portion, and a pair of drill guide members shiftably mounted in said opening and selectively shiftable into said central portion in said opening in alignment with said bones and said V-shaped portion, said guide members each having a hole therein for receiving a drill for drilling into said bones, said V-shaped portion acting as a stop for said drill to limit drill travel.
Claim 8
Dependent Claim
58 words
The clamp set forth in claim 5 further characterized in that said guide members can both be shifted in said opening to a position out of said central portion of said opening after performing its drilling function, and screw means can be inserted in said opening in alignment with the holes formed by said drills in said bones.
Claim 9
Dependent Claim
51 words
The clamp defined in claim 5 further characterized in that said threaded portion of said first member is non-circular in cross section, and said hole in said second member slidably receives said threaded portion being of a complementary shape to said threaded portion to prevent relative rotation between said clamp members.
