A surgical instrument for the dissection of bone and other tissue includes a spindle, a dissection tool and an 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.
