  • Publication number: 20150018830
    Abstract: A fixation assembly for securing parts of a sternum has a first section having a first attachment structure for securing the first section to a first sternum part. The fixation assembly includes a second section having a second attachment structure for securing the second section to a second sternum part. A mating arrangement is provided defining a mating direction and a predetermined relative position between the first and second sections in a plane perpendicular to the mating direction. At least one holding member is provided for detachably holding the first and second sections in an abutting relationship in the predetermined relative position. This may be achieved in one variant by simultaneous engagement of the first and second sections substantially along the mating direction.

  • Publication number: 20140364860
    Abstract: A bending instrument for a surgical element has two branches or arms which are pivotable relative to one another. A bending punch and two counter members are provided. The counter members interact with the bending punch to deform the surgical element. An actuator for the bending punch is adapted to convert an actuating movement of the branches or arms into a linear movement of the bending punch in a direction towards a region between the two counter members in order to bend the surgical element therebetween. First and second bending structures are provided for co-operatively bending the surgical element, wherein the bending instrument is configured to convert an actuating movement of the branches into a mating movement of the first and second bending structures towards one another.

  • Publication number: 20140249585
    Abstract: The invention relates to a surgical retaining instrument for bone plates. The retaining instrument comprises a carrying element and two plate retaining jaws arranged on the carrying element. The mutual distance of the plate retaining jaws can be changed in order to pick up or release a bone plate. Furthermore, an actuating device is provided, which has two arms, which can be moved relative to each other and which are designed to change the mutual distance of the plate retaining jaws. The carrying element is rotatably mounted relative to the arms.

  • Publication number: 20140163576
    Abstract: A surgical distance adjusting assembly for a distractor has a base having a first connecting portion configured to hold a first bone attachment member and a carrier having a second connecting portion configured to hold a second bone attachment member. The base and the carrier are movable relative to each other, wherein the first and second connecting portions provide a releasable mechanical coupling to the first and second bone attachment members. The releasable mechanical coupling comprises a hook member at one or both of the first and second connecting portions and configured to engage the respective bone attachment member. Alternatively, the releasable mechanical coupling comprises an opening at one or both of the first and second connecting portions. The opening has a thread for a fixation screw configured to releasable couple the respective bone attachment member to the respective connecting portion.

  • Publication number: 20130245368
    Abstract: A surgical power tool has a head portion having a tool with a tool axis, a shaft which is connected to the head portion for guiding the head portion to the surgical site and a handle portion for exerting pressure to the head portion along the tool axis. The shaft has a longitudinal axis that is angled with respect to the tool axis. A second handle is coupled to the shaft intermediate the head portion and a gripping portion of the shaft for applying a force along the tool axis.

  • Patent number: 8491601
    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: 7682361
    Abstract: The invention relates to a self-retaining implant for fixing a bone cover or a bone fragment in an opening in a skull bone. The implant comprises a support element with an upper side and an lower side facing the bone cover. Arranged on the lower side of the support element is an extension, which supports a spike preferably extending parallel to the support element. The spike can be driven laterally into the bone cover or bone fragment by means of a driving-in device according to the invention. The driving-in device according to the invention comprises a receiving element for the implant. A driving-in mechanism for driving the implant into the bone cover or bone fragment can be coupled with the receiving element.
