Abstract
This invention relates to an improved guarded surgical scalpel having a movable guard that can be retracted to expose the blade and that can be extended to cover the sharp cutting edge of the blade. The guard is telescopically mounted inside the blade handle and includes a deflectable top wall portion that holds a detent pin. This detent pin engages a slot having upturned ends that is formed in at least one side wall of the blade handle. The detent pin is biased upwardly into the upturned ends to hold the guard in the retracted or extended position.
