Abstract: 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.

Abstract: A surgical power tool includes a hand unit and a tool holder. The tool holder engages a hub of a tool to hold the tool during use. One tool holder includes a substantially planar support surface, a pair of spaced-apart sidewalls protruding from the support surface, each sidewall having at least one tab extending from the sidewall toward the other of the sidewalls. A tool clamp, including a post protrudes from the support surface with an enlarged head at a distal end thereof. A lock button protrudes from the support surface, the lock button being depressible toward the support surface. Another tool holder includes an output shaft having a driven end and a free end, the free end of the output shaft having a slot formed therein. A collet is disposed coaxially with the output shaft and is rotatable relative thereto. The collet has a collet wall extending between the first and second ends of the collet.

Abstract: A surgical power tool includes a hand unit and a detachable power module received in the hand unit to provide power to the hand unit. The power module includes a housing, an electric motor in the housing to provide mechanical energy to the hand unit, an electrical power supply in the housing to provide electrical energy to the electric motor, and an electronic controller in the housing for controlling the electric motor. Since the power module is received in the hand unit, there is no need for the power module to be sterilized.

Abstract: 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.
