Abstract
A small housing which may be held in the hand of a surgeon has an open ended socket into which a rotary bur assembly may be inserted and latched in place. A driven gear on the rotary bur assembly meshes with a driving gear at the end of the socket. The rotary bur assembly includes a sleeve supporting the bur on axially spaced bearings, and the sleeve has an external annular shoulder. A latch moves through a side window in the housing to engage the annular shoulder to hold the gears in proper mesh, and a spring prevents accidental disengagement of the latch.
