摘要：
Methods and devices for blunt dissection include a differential dissecting instrument (DDI) comprising a rotary drive train having a distal end configured to be pointed substantially at a complex tissue and a proximal end pointed substantially at, and associated with, a mounting base. The DDI comprises a drive wheel possessing an axis of wheel rotation coaxial with a central, longitudinal axis of the rotary drive train, the drive wheel located distally to, and rotated by, the rotary drive train. The drive wheel comprises a drive point located at a non-zero radius from the axis of wheel rotation. The DDI also comprises a differential dissecting member rotatably mounted distally to the drive wheel and having an axis of member rotational oscillation.
