  • Patent number: 11027497
    Abstract: A method of anchoring a connector in a heterogeneous first object that includes a first building layer and, distally of the first building layer, an interlining layer. The method includes providing the first object and the connector, which includes thermoplastic material in a solid state; contacting the connector with the first building layer; applying a first mechanical pressing force to the connector until the first building layer is pierced by the connector and a distal portion of the connector reaches into the interlining layer; applying a second mechanical pressing force and mechanical vibration to the connector until a flow portion of the thermoplastic material is flowable and penetrates structures of the first object, and a distally facing abutment face of the head portion abuts against the metal profile in a region next to the opening; and letting the thermoplastic material resolidify to yield a positive-fit connection.

  • Publication number: 20210161519
    Abstract: A suture anchor includes a material having thermoplastic properties and is fixated in a hard tissue opening by liquefying at least part of this material and letting it penetrate into walls of the hard tissue opening. During the named fixation and preferably towards the end of it, the suture being held in a distal suture conduit is locked relative to the hard tissue by being clamped between the suture anchor and the wall of the hard tissue opening or by being clamped or braked through collapse of the suture conduit.

  • Publication number: 20210162675
    Abstract: A cover layer is joined to an object by a pressing force and mechanical vibration. The cover layer has a cover layer contact surface, and the object has an object contact surface, and the cover layer contact surface and the object contact surface face each other. At least one of the cover layer and the object include a joining material. The cover layer contact surface is brought into contact with the object contact surface, and a sonotrode presses the cover layer against the object and applies mechanical vibration to an outer surface of the cover layer for a time sufficient for activating the joining material. Cover layer and object are conveyed relative to the sonotrode in a continuous manner in a conveying direction throughout the steps of arranging, of bringing into contact, of pressing and of applying vibration.

  • Publication number: 20210129450
    Abstract: A method for joining two objects by anchoring an insert portion provided on one of the objects in an opening provided on the other one of the objects. The anchorage is achieved by liquefaction of a thermoplastic material and interpenetration of the liquefied material and a penetrable material, the two materials being arranged on opposite surfaces of the insert portion and the wall of the opening. Before such liquefaction and interpenetration, an interference fit is established in which such opposite surfaces are pressed against each other, and, for the anchoring, mechanical vibration energy and possibly a shearing force are applied, wherein the shearing force puts a shear stress on the interference fit.

  • Publication number: 20210122121
    Abstract: A method of anchoring a lightweight building element having a first building layer and an interlining layer distally of the first building layer, and possibly a second building layer distally of the interlining layer. For anchoring, the the distal end of a connector element is inserted into a mounting hole in the lightweight building element, and also a sleeve including a thermoplastic material is inserted into the mounting hole, the sleeve enclosing the connector element. Then, a distally facing liquefaction face of the sleeve is caused to be in contact with a proximally facing support face of the connector element. Energy impinges to liquefy at least a flow portion of the thermoplastic material of the sleeve, and the liquefaction face is pressed against the support face to cause at least a fraction of the flow portion to flow radially outward. After the flow portion has re-solidified, it anchors the connector element in the receiving object.

  • Patent number: 10807313
    Abstract: A profile body of a not liquefiable material is used as a connecting element between a first object and a second object. The profile body may especially be metallic and/or may be bendable. The profile body, in contrast to a conventional wire, however, has a shape defining a first and a second undercut. The method includes embedding the profile body in the second object so that the second undercut is within material of the second object, and embedding the profile body within material of the first object so that the first undercut is within the first object, and wherein at least embedding of the profile body in the first object is caused by mechanical energy impinging on the first object and/or on the second object while the first object and the second object are pressed against each other.

  • Patent number: 10722369
    Abstract: The fusion device for fusing a synovial joint of a human or animal patient, in particular a human facet joint, finger joint or toe joint, includes two pin-shaped anchorage portions and arranged therebetween a stabilization portion. The anchorage portions include a thermoplastic material which is liquefiable by mechanical vibration. The stabilization portion preferably has a surface which is equipped for enhancing osseointegration. The anchorage portions have a greater thickness and a greater depth than the stabilization portion. Then the fusion device is pushed between the articular surfaces and mechanical vibration, in particular ultrasonic vibration, is applied to the proximal face of the fusion device. Thereby the liquefiable material is liquefied where in contact with the bone tissue and penetrates into the bone tissue, where after re-solidification it constitutes a positive fit connection between the fusion device and the bone tissue.
