#$%^&*AU2019253899A120191114.pdf#####METHODS AND DEVICES FOR SOFT TISSUE DISSECTION ABSTRACT An instrument (4200) for differentially dissecting complex tissue is disclosed, comprising a handle (4210), a central longitudinal axis, and an elongate member (4220), with a differential dissecting member (DDM) (4250) configured to be rotatably attached to a distal end. The DDM (4250) comprises at least one tissue engaging surface (4251), a first torque-point (4253) disposed to a first side of an axis of rotation, and a mechanism configured to rotate the DDM (4250) around the axis of rotation, causing the tissue engaging surface (4251) to move in at least one direction against the complex tissue. The mechanism (4250) comprises at least one force-transmitting member (4261) attached to the first torque-point member (4253) and to a motive source configured to oscillate the DDM (4250). The tissue engaging surface (4251) is configured to selectively engage the complex tissue such that it disrupts at least one soft tissue in the complex tissue, but does not disrupt firm tissue in the complex tissue.
