ABSTRACT:
An apparatus is disclosed whereby a detachable surgical blade is easily and effectively removed from blade handle adapted for use with detachable surgical blades. The apparatus is a two part assembly comprising a scalpel handle and a blade release slide element. The handle includes a blade mounting tang on the proximal end thereof and a grip on the distal end thereof. The handle has dimensions such that a portion of the rear edge of the scalpel blade protrudes latitudinally beyond the perimeter of that portion of the grip adjacent to the tang. The blade release slide element is slidably mountable on the handle and is of a length such that, when in assembled relation with the handle, the blade release slide element extends forwardly from an intermediate section of the grip to a section of the grip rearward of the tang. The blade release slide element has a blade engaging and release ramp which inclines from the proximal end of the handle to the distal end of the handle as the blade mounting portion of the tang extends upwardly. Removal of the blade is accomplished by a one handed digitally activated sliding movement of the blade release slide element towards the proximal end of the handle whereby the blade engaging and release ramp engages the protruding portion of the rear edge of the blade causing the rear portion of the blade to flex upwardly and slide forward off the tang.
