Various embodiments provide surgical cutting devices and systems for orthopedic and other procedures. Specific embodiments provide saw devices for accessing and cutting subjacent bone and other tissue while minimizing injury to surrounding tissue. One embodiment provides a transverse acting saw blade for performing surgical cuts to bone tissue with minimal injury to surrounding tissue. The blade comprises an elongated member having a first portion and a second portion and a longitudinal and lateral axis. The first portion is configured to engage a drive source to produce longitudinal movement of the first portion that is atraumatic to surrounding tissue. The second portion includes a cutting surface. The longitudinal movement of the first portion is converted to a lateral movement of the second portion that is sufficient to cut engaged bone tissue with the cutting surface. The movement of the second portion is substantially transverse to the movement of the first portion.
