A surgical instrument for the dissection of bone and other tissue includes a spindle, a dissection tool and a coupler disposed between the spindle and the dissection tool. The coupler includes a tool collet and an attachment locking mechanism operable to permit tool collet operation and telescoping movement of an attachment tube with respect to the dissection tool. A method is also provided for convenient coupling of the dissection tool and adjustment of the attachment tube length.

A surgical instrument for the dissection of bone and other tissue includes a spindle, a dissection tool and a male member carried by the spindle. The spindle includes a cavity. 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 and a second end having a generally cylindrical cross-section and a centrally located aperture partially extending along the axis. The male member is carried by the spindle and extends into the aperture of the dissection tool.

Surgical instrument with rotary cutting member and quick release coupling arrangement

A surgical instrument for the dissection of bone and other tissue includes a spindle, a dissection tool and a male member carried by the spindle. The spindle includes a cavity. 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 and a second end having a generally cylindrical cross-section and a centrally located aperture 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 may extend from the drive portion into the tool receiving aperture.

A surgical instrument for the dissection of bone and other tissue includes a spindle, a dissection tool and an adaptor disposed between the spindle and the dissection tool. The spindle includes a cavity and a male member projecting into the cavity. The adaptor includes a drive shaft that extends along an axis and includes a first end having a generally cylindrical cross-section and a centrally located aperture 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 may extend from the drive portion into the tool receiving aperture.
