A surgical instrument has a motor including a chuck for releasably receiving a dissecting tool for rotation about an axis of the surgical instrument. The dissecting tool has a cutting end and a shaft and the surgical instrument is provided with a base releasably connected to the motor. A sleeve is releasably connected to the base to support the shaft of the dissecting tool, and the surgical instrument is further provided with sleeve connection means for selectively permitting axial movement of the sleeve relative to the base and the dissecting tool to vary the amount of protrusion of the cutting end of the dissecting tool from the sleeve.
