  • Patent number: 10722270
    Abstract: A system for establishing an anchorage in an operation site of a human or animal patient with the aid of a material having thermoplastic properties and vibration energy. The system includes a transmitting piece connected or connectable to an energy source for generating vibration energy, and a housing with an opening. The transmitting piece is arranged moveably within the housing, the opening being adapted to the transmitting piece for a distal portion of the transmitting piece to be able to protrude from the opening. The system also includes a driver being activatable for exerting a compression force on the transmitting piece, and a thermoplastic element arranged to be compressible between the transmitting piece and a counter element by the compression force. Furthermore, the system is equipped for shock-free initial positioning and pre-pressing of the transmitting piece against the thermoplastic element.

  • Patent number: 10390957
    Abstract: A human or animal joint is treated by introduction of a device between the suitably prepared articulating surfaces of the joint, and the device is anchored in both these articular surfaces with a material having thermoplastic properties. For allowing at least limited articulation of the joint after implantation, the device includes two articulating portions, wherein one of the articulating portions is anchored in each articulating surfaces of the joint. On implantation a proximal face of the device is contacted with a vibrating tool and the vibration is transmitted through parts of the device to locations in which the material having thermoplastic properties is near the bone tissue of the articulating surfaces of the joint and in which liquefaction is desired. The liquefied material penetrates the bone tissue and, on re-solidification forms a positive fit connection between the device and the bone tissue.

  • Patent number: 10195045
    Abstract: A spine stabilization device having an interbody spacer shaped to be inserted between a vertebral body of an upper vertebra and a vertebral body of a lower vertebra. The device further includes a fixation device to be inserted after placement of the interbody spacer, the fixation device having a support portion securing the interbody spacer against escaping from between the vertebral bodies into a ventral direction. The support portion rests against a portion of an anterior surface of the interbody spacer, and includes an anchor. The anchor has an anchoring material portion that is inserted, in a liquid state, into cancellous bone tissue of at least one of the vertebral bodies of the upper and lower vertebra, to thereby infiltrate the cancellous bone tissue, and to harden thereafter so as to fix the support portion to the vertebral body.

  • Patent number: 9943350
    Abstract: A method for automated implantation of an implant or for an automated augmentation process of hard tissue and/or hard tissue replacement material using a sheath element is provided. The implantation apparatus includes a casing, a converter operable to generate mechanical vibrations the converter inside the casing and displaceable in a longitudinal direction relative to the casing, and a sonotrode coupled to an output location of the converter. A shaft portion with a retention structure is rotationally coupled to the casing and is equipped for cooperating with a rotationally asymmetric element of the sheath element to rotationally couple the casing to the sheath element. An axial coupling is equipped for locking the casing to the sheath element. The shaft portion, the axial coupling and the sonotrode are mutually arranged so that the distal end of the sonotrode may be introduced into a longitudinal opening of the sheath element.

  • Patent number: 9844402
    Abstract: An anterior cervical includes a plate portion for stabilizing a human or animal spine by being placed ventrally of the spinal column and affixed to two or more different vertebral bodies, and a plurality of fastening portions adapted to be anchored in the different vertebral bodies. At least one of the fastening portions is rigidly connected to the plate portion and includes a sheath element with a longitudinal opening that is accessible from a proximal side and at least one hole that reaches from the longitudinal opening to an outside. The anterior cervical plate further includes a thermoplastic element that may be inserted in the sheath element and that is capable of being liquefied by, for example, mechanical energy acting on the thermoplastic element.
