  • Publication number: 20140114362
    Abstract: A screw for fixation of, for example, a fracture having a hollow shaft, a first outer thread and radial openings at its distal end, and a second outer thread and an inner engagement portion at its proximal end. The second outer thread is adapted to engage with a tissue protection sleeve. The inner engagement portion is adapted to fit to a driving end of a driving tool. By way of this, forces in axial or radial direction may be applied to the screw by the sleeve, and forces in rotational direction may be applied by the driving tool. Therefore, the screw can be installed accurately at the intended site in an object.

  • Publication number: 20140079303
    Abstract: Disclosed herein are systems and methods for automatic detection of clinical relevance of images of an anatomical situation. The method includes comparing a first image and a second image and determining whether a difference between the first and second images is at least one of a local type difference and a global type difference. The local type difference is a local difference of the first image and the second image and the global type difference is a global difference between the first image and the second image. The second image is determined as having a clinical relevance if it is determined that the difference between the first image and the second image comprises a local type difference.

  • Publication number: 20130345764
    Abstract: A device and method for fixation of bone fractures has a bone screw comprising a shank with a threaded end portion, on the outer surface. The screw has a through bore with two bore portions differing in diameter. A step in the diameter is formed between these bore portions and is located within the end of the screw having the thread. This step in diameter can support a metal insert which in turn supports a polymer pin when the latter if pressurized with a sonotrode in the bone screw. Together with an applied ultrasonic vibration the pressure fluidizes the polymer pin and presses the material through holes configured in the wall of the bone screw and into surrounding bone.

  • Patent number: 8551124
    Abstract: An implantation pin for implantation in a target structure has a pinhead and a shaft. The pinhead comprises a pinhead molding portion comprising a moldable material which can be liquefied by application of mechanical energy such as ultrasonic vibration energy. A channel extends through the pinhead and the shaft, the channel connecting the pinhead molding portion to a discharge opening located at the shaft. The moldable material can be liquefied by applying mechanical energy e.g. in the form of ultrasonic vibrations via e.g. a fixation device including an ultrasonic sonotrode and a vibrating tip. The pressure applied by the vibrating tip can be transmitted via the border of the pinhead to the target structure while the liquefied moldable material can be forced through the channel and the discharge opening into a gap between the implantation pin and a recess in a target structure thereby fixing the implantation pin in the target structure.
