Abstract:
1. A medical handpiece for dispensing filling material on one or more of a human tissue, an animal tissue, a prosthesis for human tissue, and a prosthesis for animal tissue, the handpiece comprising: a connection device for coupling the handpiece to a filling material container, a vibration unit for generating and transmitting vibrations to the filling material and a conveying device for conveying the filling material from the container, wherein the vibration unit comprises a vibration exciter and a sonotrode coupled to the vibration exciter, and wherein the sonotrode and the connection device are movable relative to each other for conveying the filling material from the filling material container in a first mode of movement by which the sonotrode transmits vibrations generated by the vibration exciter onto the filling material substantially without any net displacement and in a second mode of movement by which the sonotrode is displaced towards the connection device to push the filling material from the filling material container.
