Patent number: 7935126Abstract: Removable guide tips are pre-assembled into threaded holes of a fracture fixation plate. The guide tips may be used with or without drill guides to guide a drill along the axes of threaded holes defined in the plate. In addition, the tips may be used with bending tools to contour the plate laterally, longitudinally and with twist. More particularly, such plate contouring can be performed while the plate is located on the bone.Type: GrantFiled: July 25, 2006Date of Patent: May 3, 2011Assignee: Depuy Products, Inc.Inventors: Jorge L. Orbay, Javier E. Castaneda, Juergen A. Kortenbach, Robert Sixto, Jr.

Publication number: 20110092981Abstract: A bending tool is provided for reshaping a bone plate that is preassembled with a pair of spaced-apart threaded, cylindrical elements removably attached to the bone plate and extending above the top surface of the bone plate. The bending tool has a handle and a distal head attached to the distal end of the handle. The distal head has a cavity that is sized and shaped to fit over the pair of spaced-apart threaded, cylindrical elements. The user, while holding the bone plate, may manually apply a leverage force to the bending tool while the cavity of the distal head is fitted over the pair of spaced-apart threaded, cylindrical elements to transmit a sufficient, regionalized bending moment to the bone plate through the pair of threaded, cylindrical elements to reshape the bone plate.Type: ApplicationFiled: October 15, 2009Publication date: April 21, 2011Inventors: Ho-Kin Ng, Priya Prasad

Publication number: 20090318979Abstract: A system for contouring a locking plate includes a locking plate and at least one bender. The locking plate includes a plurality of threaded screw holes connected to one another by one or more ribs. The at least one bender includes a threaded tip configured to threadably engage one or more of the plurality of threaded screw holes and a shoulder operable to transmit mechanical force to the locking plate once the threaded tip is threadably engaged with one of the plurality of threaded screw holes.Type: ApplicationFiled: June 20, 2008Publication date: December 24, 2009Applicant: OsteoMed L.P.Inventors: Aaron Truett Raines, Brandon G.

Publication number: 20090222020Abstract: Bending forceps (10) for surgical elements such as bone plates (30) are described. The bending forceps (10) have two branches (12, 14) which can pivot relative to one another and with together two counter bearings (26, 28) for the surgical element to be bent. A bending punch (32) for co-operation with the surgical element is provided in a region between the two counter bearings (26, 28). An actuating movement (40) of the branches (12, 14) is converted into a linear movement of the bending punch (32) in the direction of the surgical element by means of an actuating device (40), for example an elliptical linkage gear mechanism.Type: ApplicationFiled: June 22, 2006Publication date: September 3, 2009Inventors: Manfred Schmuck, Karl Greiner, Ludger Klein

Patent number: 7473257Abstract: Bending pliers are described for perforated bone plates with two jaws movable relative to one another. A receiving jaw has two spaced receptacles for insertion into holes of a bone plate to be received. A pressure-exerting jaw comprises a pressure-exerting element which, when the bending pliers are actuated, cooperates with a received bone plate in a region between the two receptacles. The receptacles have an outside diameter which is variable along their axial extent in order to cooperate, preferably in a form-fitting manner, with different hole types.Type: GrantFiled: January 16, 2004Date of Patent: January 6, 2009Assignee: Stryker Leibinger GmbH & Co.
