  • Patent number: 10105134
    Abstract: A surgical staple for compressing bones or bone fragments includes a first leg, a second leg, and a bridge monolithically formed with the first and second legs. The bridge has a first end section from which the first leg extends and a second end section from which the second leg extends. A connection between the first leg and the first end second forms a cross-sectional profile, and the bridge has an engagement portion at the first end section that extends away from the cross-sectional profile for engagement with an external tool to adjust the staple from a relaxed state to an expanded state. When the staple is in the relaxed state, at least a portion of the bridge is bent or curved, and free ends of the legs are closer to one another than are portions of the legs connected to the bridge.

    Abstract: 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.

  • Publication number: 20110092981
    Abstract: 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.

  • Publication number: 20090222020
    Abstract: 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.

  • Patent number: 7473257
    Abstract: 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.

  • Patent number: 7131975
    Abstract: A straightening tool is disclosed for straightening angled tissue cutting instruments including an outer member having a proximal length portion and a pre-formed bend connecting the proximal length portion with a distal length portion extending from the bend at an angle to a distal end, and a flexible inner member movably disposed in the outer member to cut anatomical tissue. The straightening tool comprises a handle and a positioning block extending from the handle coaxial with the straightening tool. The positioning block has a longitudinal bore for receiving the distal length portion therethrough to position the distal end within a cavity of the positioning block and the bend within a longitudinal slot of the positioning block with the proximal length portion extending externally through an opening of the slot.

  • Patent number: 6827720
    Abstract: A system and method for treating a necrotic section of bone. At least one channel is drilled into a bone from a common point. Each channel has a distal end that terminates proximate the necrotic section of bone. A volume of bone growth inducing compound is introduced into each channel. The volume of bone growth inducing compound is biased toward the distal end of each channel with a screw. The screw provides immediate structural support while the bone growth inducing compound permeates the necrotic section of bone. Once the bone growth inducing compound has permeated the necrotic section of bone, it promotes rapid bone growth and thus healing of the necrotic section of bone.
