Abstract
Abstract The device is a surgical instrument having a pair of pivotally mounted surgical blades for removing a conical section, which blades are coupled by linkage means so that their angular movement is controlled as the handle means acts as a sleeve to permit angular rotation of the supporting means with which the blades coact. The linkage means includes a pair of pivotally mounted support arms which in their extended position extend outwardly from the supporting means and in their retracted position partially extend within a slot in the supporting means and in overlapping relation to each other.
