Abstract
The invention relates to a bolt-like ultrasound anchor (1) which at the forward end changes by means of an annular step (3) by way of a desired breaking point (6) integrally into a truncated-cone-shaped expander body (4) and which is provided with slots (5) arranged windmill-like on generating lines of the expander body (4). Together with the annular step (3), the slots (5) form the desired breaking point (6). As a result of the action of ultrasound, the expander body (4) is separated from the ultrasound anchor (1) at the desired breaking point (6) and the ultrasound anchor (1) is pushed onto the expander body (4) and in so doing expanded. In addition, as a result of the action of ultrasound, welding of the ultrasound anchor (1) to the expander body (4) and sintering in a drilled hole take place.
