  • Patent number: 9924988
    Abstract: A method for locating a material having thermoplastic properties in pores of bone tissue includes providing a pin having the material having thermoplastic properties and a core, wherein the material having thermoplastic properties is arranged on the circumferential surface of the core constituting an outer region of the pin. An opening is provided in the bone tissue, and the pin is positioned at least partly in the opening. The outer region of the pin is then impinged with mechanical vibration energy for a time sufficient for liquefying at least part of the material having thermoplastic properties, and, in a liquefied state, pressing it into the pores of the bone tissue surrounding the opening. The vibration energy is stopped for a time sufficient for re-solidification of the liquefied material, and then the core is removed.

  • Patent number: 9801673
    Abstract: An implant suitable for being anchored with the aid of mechanical vibration in an opening provided in bone tissue. The implant is compressible in the direction of a compression axis under local enlargement of a distance between a peripheral implant surface and the compression axis. The implant includes a coupling-in face which serves for coupling a compressing force and the mechanical vibrations into the implant, which coupling-in face is not parallel to the compression axis. The implant also includes a thermoplastic material which, in areas of the local distance enlargement, forms at least a part of the peripheral surface of the implant.

  • Publication number: 20170305073
    Abstract: A first object is anchored in a second object. The first object has a material with thermoplastic properties, and the second material has a material that is solid and is penetrable by the first material when in a liquefied state. The second object has an insertion face with an opening having a mouth in the insertion face, and the first object has an insert portion that for anchoring is placed in the opening or about the mouth thereof. For anchoring, energy suitable for liquefaction of the first material impinges in an amount and for a time sufficient for at least partial liquefaction of the first material and interpenetration of the first and second materials. The second object, around the opening, has an anisotropic strength with respect to forces perpendicular to the opening axis.

  • Publication number: 20170297271
    Abstract: A joining element has an anchoring portion for in-depth anchoring in the object and a head portion arranged proximally of the anchoring portion with respect to an insertion axis. The head portion has a lateral outer surface that has a structure that is well-defined, especially within tight tolerances. The joining element is positioned relative to an object of a non-liquefiable material such that the anchoring portion reaches into an opening of the object or is placed adjacent a mouth thereof. Then, the joining element is pressed towards a distal direction, to press the anchoring portion into the opening, while mechanical vibration energy is coupled into the joining element by a tool, in an amount and for a time sufficient for liquefaction of a portion of the thermoplastic material to cause interpenetration of the thermoplastic material into structures of the object.

Each one of the parts includes a joining location, the two joining locations facing each other when the device parts are positioned for being joined together, wherein one of the joining locations includes a material which is liquefiable by mechanical vibration and the other one of the joining locations includes a material which is not liquefiable by mechanical vibration and a structure (e.g. undercut cavities or protrusions) suitable for forming a positive fit connection with the liquefiable material. The joining process is effected by pressing the two device parts against each other and by applying ultrasonic vibration to one of the device parts when the two parts are positioned relative to each other such that the two joining locations are in contact with each other.

  • Patent number: 9662159
    Abstract: An ultrasonic handpiece is used for augmenting a bone screw. The handpieces comprise a housing, an ultrasonic converter shiftingly accommodated in the housing, and a sonotrode connected to one end of the ultrasonic converter. The sonotrode protrudes from the housing into the bone screw. An adjuster wheel is adjustably connected to the housing. A spring is provided the ends of which are supported by the ultrasonic converter and the adjuster wheel, respectively. The ultrasonic converter is preloaded in the direction away from the adjuster wheel by setting the adjuster wheel, thereby the sonotrode is urged with a selected force into the bone screw and the augmentation material is pressed out of the bone screw and into the bone.
