Abstract
Methods and devices for blunt dissection include a drive mechanism comprising an elongate rotary drive train having a first proximal end connected to a mounting base for attaching to a handle or a surgical robot and a second distal end. The drive mechanism comprises a differential dissecting member (DDM) configured to be rotatably attached to the second distal end. The drive mechanism further comprises a mechanism configured to mechanically rotate the DDM about a substantially transverse axis of member rotational oscillation, thereby causing at least one tissue engaging surface to move in at least one direction against complex tissue and selectively engage the complex tissue such that when the DDM is pressed into the complex tissue, the at least one tissue engaging surface moves across the complex tissue and disrupts at least one soft tissue in the complex tissue, but does not disrupt firm tissue in the complex tissue.
