Abstract: Disclosed is a fenestrated bone anchor suitable for being anchored in live bone tissue of a human or animal patient. The bone anchor comprises a shaft with a proximal end and a distal end and a circumferential surface extending from the proximal end to the distal end. The shaft further comprises a longitudinal cavity extending from the proximal end towards the distal end and a plurality of lateral channels extending through a wall of the shaft from the axial cavity to the circumferential surface. The lateral channel has a pear-shaped cross section and/or the thickness of the wall increases gradually in selected ones of directions towards the lateral channels. The fenestrated bone anchor is e.g. a component of a surgical system comprising an interbody fusion device of the stand-alone type.

Abstract: A surgical apparatus generates energy that is input onto an appliance. The appliance is one of an implant to be implanted in human or animal bone tissue by the input of the energy, and of a tool being an ultrasonic bone cutting and/or punching tool for cutting and/or punching living human or animal bone tissue by input of energy onto the implant in a surgical operation. The apparatus includes a control device and at least one handpiece, the handpiece being equipped to be held by a surgeon during the operation and to couple the energy into the appliance. The apparatus further includes a reading device equipped to read out, from an appliance data carrier, appliance data dedicated to the appliance. The control device checks, depending on the appliance data, whether the handpiece is suitable for the appliance and chooses operating parameters depending on the appliance data.

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.
