Abstract

The inventive device is a mechanical wave inducing device being connectable to a needle. The device has a displacement source and a driving signal connection part in order to connect the displacement source to a signal source. The device has also two connections parts, which are connected to the displacement source, and which each wing part has a connection point to be attached with the needle. The wing parts are converters in order to convert longitudinal mechanical wave movement created by the displacement source into transversal mechanical wave movement for the needle, and at least one connection point is designed to match the transversal mechanical waves to the needle.
