Patent ID: 8728134

Claim:
A method for implanting an implantation pin in a target structure comprising providing an implantation pin consisting entirely of a material which can be liquefied by applying ultrasonic vibrations, the implantation pin comprises a pinhead, a shaft comprising a discharge opening wherein a channel extends internally along and through the pinhead and the shaft, the channel connecting the pinhead molding portion to the shaft discharge opening, wherein material of the pinhead molding portion when liquefied by applying ultrasonic vibrations, can be pressed through the channel and out of the discharge opening; inserting the implantation pin into bone and applying ultrasonic vibrations with an ultrasonic sonotrode comprising a vibration shaft adapted to generate ultrasonic vibrations at a tip provided on the vibration shaft wherein the tip on the vibration shaft has a width being smaller than a width of the shaft of the implantation pin and being larger than a width of the channel within the shaft of the implantation pin; and guiding the vibrating tip of the ultrasonic sonotrode with a guiding mechanism adapted to cooperate with the implantation pin in order to align the guiding mechanism with respect to the implantation pin.
