  • Publication number: 20230355285
    Abstract: A method is disclosed for manufacturing a fiber-reinforced implant structure. A fiber-reinforced rigid insert is provided, comprising continuous fibers impregnated with a first thermoplastic polymer. A molding cycle is performed by overmolding. The insert is placed into a mold cavity; and a second thermoplastic polymer in melted form is injection or compression molded into the mold cavity. The insert is thus at least partly covered by the second thermoplastic polymer. The second thermoplastic polymer injection or compression in the mold cavity is cooled, thereby obtaining a molded fiber-reinforced implant structure containing the at least partly covered insert. The insert is in a predefined location in the mold cavity during said injection or compression molding and during said cooling. The first thermoplastic polymer and the second thermoplastic polymer are the same or different. Also disclosed is an implant structure, and an implant comprising said implant structure.

  • Publication number: 20160206306
    Abstract: A method for fixation of soft tissue to bone. A permanent fixing site of the tissue in the bone is selected. A temporary locking site of the tissue in the bone is selected. The temporary locking site is at a distance from the permanent fixing site. A fixing length of the tissue is selected that corresponds a tension state of the tissue. The tissue is temporarily fixed at the permanent fixing site. The tissue is locked at the temporary locking site in a position corresponding to the fixing length. The tissue is permanently fixed to the permanent fixing site. The locking of the tissue is released at the temporary locking site after permanently fixing the tissue. The locking of the tissue at the temporary locking site is carried out by a holder that has a lock to contact the bone, and a grip separate from the lock for gripping the tissue.

  • Patent number: 7824428
    Abstract: The present invention relates a system to be used with an implanting tool having a tip part. The system has a longitudinal axis and comprises a polymeric screw (31) having a head (11) and an adapter between the screw (31) and the implanting tool. The adapter comprises a first part (32) which fits the tip part of the implanting tool. The first part comprises a first element and the system comprises a second element. The first element and the second element are connected to each other with a torque limiting junction having a first maximum torque when the screw is screwed in and a second maximum torque when the screw is screwed off. The shape of the first element and the second element is such that the second maximum torque of the torque limiting junction is greater than the first maximum torque, thus allowing the removal of the polymeric screw (31) from its position.
