Abstract
A system for establishing an anchorage or augmentation in hard tissue with the aid of a material having thermoplastic properties, which is brought to the site of the anchorage or reinforcement in a solid state, is liquefied in situ, and, in a liquefied state, is displaced to contact the object. The system includes a housing with a proximal housing part and mounted therein, a transmitting piece possibly coupled to an energy source and a driver spring, a distal housing part releasably coupled to the proximal housing part, a permeable sleeve couplable to the distal housing part, and a thermoplastic element positionable in the permeable sleeve. The two housing parts, the transmitting piece, the driver spring and the permeable sleeve form a closed load frame in which the thermoplastic element is compressed between the transmitting piece and the permeable sleeve.
