Abstract
An implantation pin for implantation in a target structure has a pinhead and a shaft. The pinhead comprises a pinhead molding portion comprising a moldable material which can be liquefied by application of mechanical energy such as ultrasonic vibration energy. A channel extends through the pinhead and the shaft, the channel connecting the pinhead molding portion to a discharge opening located at the shaft. The moldable material can be liquefied by applying mechanical energy e.g. in the form of ultrasonic vibrations via e.g. a fixation device including an ultrasonic sonotrode and a vibrating tip. The pressure applied by the vibrating tip can be transmitted via the border of the pinhead to the target structure while the liquefied moldable material can be forced through the channel and the discharge opening into a gap between the implantation pin and a recess in a target structure thereby fixing the implantation pin in the target structure.
