Abstract
A surgical scalpel having an extendable blade, said blade being extended by rotating a movable portion of a barrel with respect to a fixed barrel portion, the initial extension being done at a fast rate and the final extension or depth adjustment being done at a slow rate. Additionally, the invention includes a gauge in combination with the scalpel for calibrating blade depth, the gauge consisting of a base, a slidable block with a tapered ridge and width markings and a slidable support for the scalpel, so that the scalpel can be abutted with the block for measurement and backed off for block adjustment.
