Abstract
A device and method for perforating a dense bone layer. The device includes a vibration generator for generating mechanical vibration, in particular ultrasonic vibration, and an instrument with an elongated shaft and a distal end piece including a perforator. The distal end piece is arranged at a distal end of the shaft and the proximal end of the shaft is connected or connectable to the vibration generator. The perforator has the form of a solid or a hollow cylinder. The vibration generator, the shaft and the distal end piece are adapted to each other for the shaft to transmit, when connected to the activated vibration generator, mechanical vibration from the vibration generator to the distal end piece and for vibrating the perforator in a direction parallel to its cylinder axis.
