Abstract
Abstract Multifunctional instrument for ultrasound surgery having an applicator 2 for a dissection of biological tissue, as well as a device for cutting and/or coagulating of the tissue. At the instrument end separate from the ultrasound applicator 2 at least one RF-current applicator 16 or a laser applicator 15 is arranged in a lateral distance from the distal end 3 of the ultrasound applicator 2, whereby an adjustable arrangement is provided. Each applicator 2, 6, 15 is movable in longitudinal direction in a common applicator housing 9. The applicators may be provided in a revolver unit, which is arranged at the instrument and can be rotated around its longitudinal axis.
