摘要

A surgical instrument for the dissection of bone and other tissue includes a spindle (146), a dissection tool (18) and a male member carried (162) by the spindle. The spindle includes a cavity (160). The dissection tool is releasably received in the cavity. The dissection tool extends along an axis and includes a first end and a second end with the first end having a cutting element (20) and a second end (21) having a generally cylindrical cross-section and a centrally located aperture (180) partially extending along the axis. The male member is carried by the spindle and extends into the aperture of the dissection tool. The cavity may define a drive portion and a tool receiving aperture. One or more alignment projections (148) may extend from the drive portion into the tool receiving aperture.
