摘要：
A piezo-driven, vibrating beam is applicable to surgical procedures. A rod of piezoelectric material defines a length with proximal and distal ends. A pattern of electrodes, disposed adjacent to and along the length of the rod of piezoelectric material, is adapted for connection to a generator operative to stimulate the piezoelectric material, causing the rod to assume one or more vibratory states. In preferred embodiments, the proximal end of the rod of piezoelectric material is adapted for coupling to a blocking mass causing the vibratory states to be concentrated at the distal end of the rod of piezoelectric material. The pattern of electrodes may comprise interdigitated fingers, and the system may further include a material encapsulating the rod and the pattern of electrodes. Preferred embodiments may further include a plurality of coextensive, parallel rods forming a basic unit, each rod having a separate pattern of electrodes adjacent thereto.
