Abstract
A scalpel includes a blade carrier and blade shield equally movable but in opposite longitudinal directions in response to longitudinal movement of an actuator along the upper edge of the scalpel housing. Equal and opposite motion is achieved using a pinion disposed in the housing and engaged on opposite diametric sides by racks secured to the blade shield and blade carrier. The actuator is compressible to remove stop members secured thereto from respective recesses, thereby permitting movement of the blade carrier and blade shield from defined extreme positions.
